How Women Can Improve Their Fertility & Hormone Health | Dr. Natalie Crawford
Andrew Huberman
0:00 Everybody should get an AMH test.
0:01 I think it's a very important marker.
0:03 If you are listening to this and you want kids one day,
0:06 ask your doctor for this test.
0:08 It is not a test of egg quality.
0:10 And we talked about what egg quality is, right?
0:11 Genetics and egg competency.
0:14 But it is a check of how many eggs you have and that knowledge
0:18 can be really impactful for how you view your future and your plan.
0:22 Welcome to the Huberman Lab Podcast where we
0:24 discuss science [music] and science-based tools for everyday life.
0:31 I'm Andrew Huberman and I'm a professor
0:33 of neurobiology and ophthalmology at Stanford School of Medicine.
0:37 My guest today is Dr.
0:38 Natalie Crawford.
0:39 Dr.
0:39 Natalie Crawford is a double board
0:41 certified physician specializing in obstetrics and gynecology,
0:44 fertility, and reproductive health.
0:46 Today we discuss the actionable steps that all women can take to improve
0:51 their reproductive and hormone health both
0:53 to enhance probability of successful pregnancy,
0:56 but also because fertility and hormone health
0:58 are strong correlates of general health and longevity.
1:01 Dr.
1:01 Crawford shares what all women, regardless of age or reproductive goals,
1:05 can do to enhance their health using lifestyle, nutrition, supplementation,
1:10 and prescription medical tools that she indeed uses in her practice.
1:14 We also have a very honest discussion
1:16 about biological versus chronological age and fertility.
1:19 Why age is not just a number,
1:21 but also why it is that many women do successfully conceive in their 40s.
1:26 Of course, there's a lot of information online nowadays about women's hormones,
1:30 fertility, and health.
1:31 Today, thanks to Dr.
1:32 Crawford, you'll learn what is known and documented and what she has
1:36 herself consistently observed clinically in her practice
1:39 about women's health and fertility.
1:41 Few, if any, people have Dr.
1:43 Crawford's training, clinical acumen, understanding of the new research,
1:47 and incredible ability to communicate the well
1:49 and lesser-known actionable steps for improving female health.
1:53 Dr.
1:53 Crawford also has a new book out entitled The Fertility Formula:
1:57 Take Control of Your Reproductive Future,
1:59 which again focuses on reproductive health,
2:01 but also hormone health and how both of those things
2:04 impact female health in the short and long term.
2:07 Before we begin, I'd like to emphasize that this podcast
2:09 is separate from my teaching and research roles at Stanford.
2:12 It is, however, a part of my desire and effort to bring zero
2:15 cost to consumer information about science
2:17 and science-related tools to the general public.
2:19 In keeping with that theme, today's episode does include sponsors.
2:23 And now for my discussion with Dr.
2:24 Natalie Crawford.
2:26 Dr.
2:26 Natalie Crawford, welcome back.
2:28 Thank you so much for having me.
2:29 I'm thrilled to be here.
2:30 And congratulations on your new book, The Fertility Formula.
2:34 It's no small feat to complete a book and it's and it's especially
2:38 a big feat to complete a book that offers people so much advice,
2:41 not just people who want to get pregnant,
2:45 but also looking at things through the lens
2:47 of fertility as an important health metric.
2:50 Yes.
2:50 Thank you so much.
2:51 You know what goes into writing a book and it's always been this aspirational
2:55 goal of mine and after educating and talking
2:58 about fertility with patients and people online,
3:00 it's been something I've wanted to do,
3:02 but I will say it is a much bigger feat to go through it,
3:06 to work with editors, to try to refine within your word count.
3:10 I was, you know, I was 20,000 words over and try to bring it back in.
3:13 So, thank you for having me and for holding it up
3:16 and reading it early and sharing your endorsement for it, too.
3:19 That means so much.
3:20 Yeah, I I'm insisting, as much as one can insist,
3:23 that various people in my life read this book,
3:26 um, including family members and other people because, again,
3:29 it's not just about people who want
3:31 to have children or who already have children,
3:34 but fertility as a way of kind of knowing where
3:37 one is in their health arc and their life arc.
3:40 Um, so if you don't mind, um,
3:43 how should people think about fertility purely as uh a read-out of health?
3:48 I mean, what just how do you how do you frame
3:49 this for like if somebody comes to you and says, "Listen,
3:52 they have kids or they don't want kids or they're not sure if they want kids,
3:55 but um, why use fertility as a lens on general health?
4:02 Yeah, fertility is a health marker and I love that you bring
4:05 that up the top of the episode here because so often patients,
4:09 women specifically, think fertility is only the ability to get pregnant.
4:13 We really simplify it into this one phase of life.
4:16 But if we want to zoom out,
4:18 your fertility is a sign that you have good hormonal health, good cellular,
4:21 good metabolic health because it takes
4:24 so many different moving parts to ovulate,
4:27 for an egg to allow a sperm to fertilize, to implant, to get pregnant.
4:31 But also your hormonal health and the ovarian
4:33 function is really going to impact your entire life,
4:36 how you feel on a day-to-day as a woman.
4:39 But if we want to be really specific, if you have infertility,
4:43 you have increased rates of metabolic syndrome,
4:46 cancer, heart attack, stroke, and dying early.
4:50 So, those are extremely scary statistics and you know,
4:53 I had my own infertility journey, so I fall into this category.
4:57 But the reason why is not that infertility causes any of those things directly.
5:02 It's that for most people, it's one of the first warning signs that something
5:06 is not right in their body and that there's
5:08 higher levels of chronic inflammation or insulin resistance
5:12 that we know can impact long-term health outcomes.
5:16 For women who are still of reproductive age,
5:19 and I realize there's no strict cut-off,
5:21 um, we can and and certainly will talk about what are the measures,
5:26 direct and indirect, of fertility that, um,
5:28 can give them a window into their kind of health span risk factors,
5:32 life span risk factors.
5:34 For women that have already reached menopause or in perimenopause,
5:38 um, how should they think about fertility as a health marker?
5:42 Meaning, if somebody is has passed the point
5:45 where they can safely, um, get pregnant, Mhm.
5:49 does that mean that their periods are no longer informative?
5:52 I imagine their periods features about their menstrual
5:54 cycle are still very informative about their general health.
5:58 As long as you're having a menstrual cycle,
6:00 it is a sign that you're ovulating and you theoretically could get pregnant.
6:04 So, I think it's really important to say that even in perimenopause,
6:07 which is the transitional time between having regular,
6:10 appropriate hormonal function,
6:12 that reliable characteristic of the ovary responding to the brain,
6:16 this is the transition time as you're starting to get to a lower
6:18 egg count that you will eventually start to see some cycle changes,
6:22 but you also have a lot of hormone dysfunction.
6:25 But you can still get pregnant and in fact,
6:26 I see a fair amount of patients who said,
6:29 "I thought I was past that stage of my life
6:31 based on my age." But if you're still having periods,
6:34 it's a really important window into your hormonal health.
6:39 It can tell you a lot about your body,
6:41 especially if you know when you ovulate and we
6:43 can look at the distinct phases of the cycle,
6:46 the follicular phase and the luteal phase.
6:49 When we're a little bit past this, menopause by definition,
6:52 which I hate, is 12 months without a period.
6:54 So, menopause is one single day in time.
6:56 Really, it means you've been in ovarian failure
6:58 for 12 months before you'll magically get this diagnosis.
7:02 But menopause at its purest is ovarian failure.
7:05 The ovaries no longer have the capability to respond to the brain signals.
7:09 You're not going to make estrogen or progesterone anymore.
7:12 At that time, a woman's metabolic health completely changes,
7:15 but the age of which you went through
7:16 menopause really can impact your reproductive health outcomes long-term.
7:21 And some of the characteristics you might have had in your cycle
7:25 when we look backwards can inform us some about your cellular health now.
7:29 So, it's still really important to think back and move forward.
7:32 And then on a bigger scale,
7:35 we're seeing the tide turn on hormone replacement therapy
7:37 and I know that's not what this entire episode's about,
7:39 but as a reproductive endocrinologist, I love estrogen.
7:42 I love hormones.
7:44 And I think it's really important for women to know
7:45 that you can start hormone replacement therapy at any time.
7:48 So, even though long time ago we felt really
7:51 comfortable starting it right at the time of menopause,
7:55 we're starting to see benefits starting in the perimenopausal period.
7:58 We see a benefit starting at once you have menopause,
8:02 but I think it's a disservice to women to make them have no period,
8:06 ovarian failure for 12 months, no estrogen, feel terrible,
8:10 before we'll allow them to have hormone replacement therapy.
8:14 Yeah, this is such an important theme and and if I may,
8:17 um, I I realize I have to be very careful,
8:21 uh, to not draw parallels to men's hormonal health when
8:25 talking about women's hormonal health because it's not a one-for-one.
8:28 They're very distinct processes.
8:30 On the other hand, I think thematically, what I'm about to say, I believe holds.
8:34 So, hopefully it won't upset too many people, which is,
8:37 you know, for many years now, um, for reasons that, uh,
8:42 are unfair, um, hormone replacement therapy was sort of became
8:49 widely available for men before it became widely available for women.
8:52 Uh, there are reasons for this.
8:54 We don't have to go into it, but they're they're the kind of obvious ones.
8:56 Um, uh, that things were pushed to market more quickly and and so forth.
9:01 But there's been this idea, you know,
9:03 should and there it's usually testosterone replacement therapy, right?
9:07 Um, and there was this idea that unless
9:10 somebody fell below 300 ng/dL for for a male, that they weren't, um, uh,
9:17 that they shouldn't get testosterone replacement therapy.
9:19 Now it's kind of understood that if somebody chooses,
9:22 they can usually find a doctor that if they're the low end of normal,
9:26 they can push to the high end of normal or to the middle
9:28 of the of the range so that they can get their symptoms away and and just feel,
9:33 right, to optimize within the normal range.
9:34 That's sort of And so,
9:36 I'm relieved to hear that you're saying the same is true for women.
9:39 And I'm relieved to hear it because I think that having
9:42 these strict cut-offs of like no periods for a year,
9:44 well, I mean, it could take a long time to reach that.
9:47 I mean, what if it's, you know, two periods per year, right?
9:50 Does that mean that that person doesn't deserve the therapy,
9:52 which is what essentially what I think you're saying.
9:54 So, the R in hormone replacement is the dangerous letter
9:57 in my opinion because there is this notion of augmenting hormones.
10:03 Exactly.
10:03 Okay, so for forgive me for going long,
10:04 but I think the two situations it would be
10:06 great if both women and men could augment their hormones
10:10 to be at the high end of normal or wherever
10:12 puts them in a place where they're not experiencing symptoms.
10:14 Absolutely.
10:15 We know that as humans,
10:17 we now have longer lifespans, we outlive our reproductive hormones,
10:20 yet they are essential for our day-to-day function and to feel our best,
10:24 and we should at least be given the opportunity to have our symptoms evaluated,
10:29 to be offered hormone therapy if we want it,
10:32 and to not have to have these harsh cutoffs,
10:35 especially for something that can be so protective long-term.
10:39 I mean, for women we see it be cardioprotective,
10:41 it can help lower the risk of Alzheimer's disease,
10:43 of course it can be protective for your bones.
10:46 So, I love this greater discussion,
10:48 and it really stems from learning about your body,
10:51 knowing what's normal so you can advocate for what's not normal,
10:55 and really feeling like you have your own
10:56 agency over your health and your own future.
11:01 I'd like to take a quick break to acknowledge one of our sponsors, David.
11:05 David makes protein bars unlike any other.
11:07 Their newest bar, the bronze bar, has 20 g of protein,
11:11 only 150 calories, and 0 g of sugar.
11:14 I have to say, these are the best tasting protein bars I've ever had,
11:18 and I've tried a lot of protein bars over the years.
11:22 These new David bars have a marshmallow base,
11:24 and they're covered in chocolate coating, and they're absolutely incredible.
11:28 I of course eat regular whole foods.
11:30 I eat meat, chicken, fish, eggs, fruits, vegetables, etc.
11:33 But, I also make it a point to eat one or two David bars per day as a snack,
11:37 which makes it easy to hit my protein goal
11:39 of 1 g of protein per pound of body weight.
11:41 And that allows me to take
11:42 in the protein I need without consuming excess calories.
11:46 I love all the David bronze bar flavors,
11:48 including cookie dough, caramel chocolate,
11:50 double chocolate, peanut butter chocolate.
11:52 They all actually taste like candy bars.
11:54 Again, they're amazing.
11:55 But again, they have no sugar,
11:57 and they have 20 g of protein with just 150 calories.
12:01 If you'd like to try David, you can go to davidprotein.com/huberman.
12:05 Right now, David is offering a deal where if you buy four cartons,
12:08 you get the fifth carton for free.
12:10 You can also find David on Amazon or in stores such as Target,
12:13 Walmart, and Kroger.
12:14 Again, to get the fifth carton for free, go to davidprotein.com/huberman.
12:19 Today's episode is also brought to us by BetterHelp.
12:22 BetterHelp offers professional therapy with a licensed
12:25 therapist carried out entirely online.
12:27 Now, I've been doing therapy for a long time,
12:29 and I can tell you that it's a lot like physical workouts.
12:32 There are days when I want to do it,
12:33 and there are days when I don't want to do it.
12:35 But, when I finish a therapy session,
12:36 every single time I come away feeling better, knowing the time was well spent,
12:40 and that's because typically I come away with a valuable
12:43 insight or new perspective that I hadn't considered before.
12:47 Something perhaps that I'm working through with regards
12:49 to work or relationships or simply my relationship to myself.
12:53 With BetterHelp, they make it very easy to find an expert
12:55 therapist who can help provide the benefits that come from effective therapy.
12:59 They have a short questionnaire to help match you to a therapist,
13:02 and while BetterHelp has an industry-leading match rate,
13:04 if you aren't happy with your match,
13:06 you can switch to a different therapist at any time.
13:09 And it works.
13:10 BetterHelp has an average rating of 4.9 out of five
13:13 for its live sessions based on over 1.7 million client reviews.
13:17 Also, because BetterHelp is done entirely online, it's very time-efficient.
13:21 There's no driving to a therapist's office, looking for parking, etc.
13:25 If you'd like to try BetterHelp,
13:26 go to betterhelp.com/huberman to get 10% off your first month.
13:31 Again, that's betterhelp.com/huberman.
13:34 I wish that um the medical profession um
13:37 could agree on nomenclature that included hormone replacement,
13:41 the R, replacement therapy for people that are out of range.
13:45 You know, they're two too low, out of the normal reference range.
13:49 Hormone augmentation therapy um for people
13:51 that want to push within the normal range.
13:54 And then of course, there's super physiological stuff,
13:56 and that's kind of how all of this got here was
13:58 there were a bunch of mainly guys taking tons of anabolic steroids,
14:03 and then estrogen's a steroid, you know, testosterone's a steroid,
14:06 and then it just became a long road to get to this point
14:10 where people like you are able to even talk about this, right?
14:13 I mean, I think 10 years ago, I think the medical profession was not
14:16 open to the idea that a 40-year-old woman,
14:19 for instance, who had not yet undergone menopause by the strict definition,
14:23 would take estrogen.
14:24 It was seen as a risk as opposed to a benefit.
14:26 Isn't it interesting?
14:27 And, you know, by professional organizations,
14:30 they would even call it menopausal hormone therapy,
14:33 MHT, not even just hormone replacement therapy.
14:36 And I talk about this a lot with my patients,
14:37 the difference in replacing a hormone we'll use in an embryo transfer cycle.
14:42 If I'm going to give you estrogen,
14:44 you haven't ovulated, I now have to replace your progesterone.
14:47 I have to give it in a certain format
14:49 that it can get to high enough levels versus supplementing.
14:52 Your body's making some,
14:53 and we're supplementing that or augmenting it like you said to get
14:57 it to the appropriate level or to make sure we have enough.
15:01 I've given hormone therapy for a long time, right?
15:03 I've been out of practice for over 10 years,
15:05 and what's so interesting is that we'll use premature ovarian failure.
15:08 So, going into ovarian failure before age 40,
15:12 well accepted that these women need hormone replacement even
15:16 when they still have the low end of hormonal function.
15:19 So, in this population,
15:20 we've been doing it for a really long time, but for menopause,
15:24 it's been and so frowned upon because of the WHI
15:27 and fear-based tactics about what would happen with hormone replacement.
15:31 So, it's interesting, and I'm really glad to see the tide is turning,
15:35 and we're really allowing people to stand up for themselves,
15:40 to also know what's normal within their body, which sounds so common,
15:45 but if we think about it, many women have been dismissed and gaslit for so long.
15:50 And if you go to your doctor and you
15:52 talk about your painful periods or your irregular
15:54 cycles or your bloating that you have with your period
15:56 and some of these red flag warning signs,
15:59 the spotting, the this, and it gets pushed to the side,
16:02 when you start to go through actual hormonal change later,
16:05 it's really hard to then believe yourself.
16:09 And so, I think it's really important, you know,
16:12 I have a whole chapter in the book about how to learn to track your cycle
16:15 and your ovulation and really learn to see the red flags your body gives you,
16:19 not just if you want to get pregnant now,
16:20 but to know that your hormones are really functioning as they should,
16:24 and that's going to help you stand up
16:25 for yourself later when you're in this transitional period,
16:28 because perimenopause or diminished ovarian reserve like
16:31 we call it in the fertility world, I mean, that can last 5 to 10 years.
16:34 That can be a really long transitional period that women are going through,
16:38 and they deserve support if they're not feeling their best.
16:41 Are all um now I want to call it hormone augmentation,
16:45 hormone let's just call it hormone replacement for for sake of uh simplicity.
16:49 Um hormone therapies uh for women,
16:52 do they always start with estrogen when it comes to trying
16:56 to encourage fertility or push fertility or well-being out into um more years?
17:02 That's an interesting question.
17:04 I think when it comes to hormone replacement therapy in general,
17:07 we've got estrogen, progesterone, testosterone.
17:10 Most women when they start not reliably making estrogen,
17:13 that's when they really start to feel bad.
17:15 And so, typically some type of estrogen replacement,
17:18 and there's many different ways, right?
17:19 There's patches, there's pills, there's vaginal inserts, there's vaginal cream,
17:23 often helps some of the symptoms they're having.
17:26 But, progesterone alone or in combination can be a big player.
17:29 Progesterone also is not made if you're not ovulating well,
17:33 so there's this tandem where often you need both of them,
17:36 but I have some perimenopausal patients who feel great on just progesterone.
17:41 To me, testosterone's the last one we add to the mix,
17:44 and it will always depend on clinical scenario.
17:46 There's nuance.
17:48 Estrogen and testosterone can convert back and forth,
17:50 so for most women, if they are adequately being replaced on estrogen,
17:55 and they still have functioning ovaries,
17:56 so in this transitional period, they tend to not need testosterone.
18:00 But, that's never 100% of the time.
18:03 I think greater to your question about how is there a way
18:06 for us to extend the ovarian lifespan is a really good one.
18:11 We know that women who go into ovarian failure early,
18:13 so when we look at that, we call it POI,
18:15 the premature ovarian insufficiency group,
18:18 their ovaries have more inflammatory markers,
18:20 they have more chronic inflammation and fibrosis inside the ovary.
18:23 There's a higher prevalence with autoimmune
18:25 disease or chronic inflammatory disorders.
18:28 So, I think there's also something to be said,
18:30 despite having not having the perfect paper to sit here and say
18:33 that we know a variety of different things that increase chronic inflammation,
18:39 cause you to have a lower egg count,
18:41 and are associated with earlier menopause or earlier ovarian failure,
18:44 that paying attention to these factors earlier in your life,
18:47 whether it's controlling an autoimmune disease,
18:50 earlier diagnosis of Hashimoto's, whether it's treating your endometriosis,
18:55 or cultivating a lifestyle that's decreasing inflammation, right?
18:59 Avoiding certain toxins, eating anti-inflammatory foods, the type of exercise,
19:03 and how we deal with those lifestyle tenants,
19:05 that that likely has the capability to extend
19:08 our ovarian lifespan to the degree that it can.
19:11 I know these days people are very concerned about plastics, Yeah.
19:15 and you mentioned toxins, so I was going to get to this later,
19:18 but I'll just ask now.
19:19 How concerned are you about plastic water bottles and um I mean,
19:24 we can't avoid exposure to plastics, and I think one thing that Dr.
19:28 Rhonda Patrick has done nicely is to highlight the fact that the really small,
19:32 hence microplastics, are really the ones that we worry about
19:35 the most because they can get into so many tissues,
19:37 but we're constantly ingesting plastic.
19:39 Some of them are just excreted um because they're big,
19:42 but some of them get into our cells, right?
19:45 Are there any data that have you or observational um data that have
19:49 you genuinely concerned that plastics are
19:53 becoming more of an issue vis-a-vis fertility.
19:57 There definitely is concern.
19:59 I always want to frame this and you did a nice job of it,
20:01 so I'll I'll double down.
20:03 The goal when we talk about toxin avoidance is you can't avoid everything.
20:07 You cannot avoid every toxin in this world,
20:09 nor should we try to have this all or nothing mentality,
20:12 which is what so many people do.
20:14 Oh, if I can't avoid it, I just will totally ignore it then in general.
20:19 When we want to think about toxins,
20:20 there's many different mechanisms why plastics can be harmful.
20:23 When it comes to microplastics as you mentioned,
20:25 we know they can accumulate in the ovary.
20:27 So, if we want to be really transparent and simple,
20:30 your ovaries must function in order for you to make estrogen and progesterone,
20:35 in order for you to ovulate, in order for you to get pregnant.
20:38 So, if microplastics can accumulate inside the ovary,
20:42 that's obviously detrimental towards fertility or ovarian function.
20:47 On a greater scale, we know that some of the endocrine disrupting
20:51 chemicals that are in plastics have been associated with worse IVF outcomes,
20:55 lower live birth rates, longer time to pregnancy.
20:58 And these are population-based cohort studies,
21:00 so there's no randomized control trial.
21:02 So, we have to limit it.
21:05 And there's some truth to the fact
21:06 that people who might be more exposed to plastics
21:09 may have other lifestyle factors such as we
21:13 know plastics can also be in food wrappers, right?
21:16 So, maybe they have more of an ultra-processed food diet.
21:18 So, it's never one specific thing.
21:21 But I look at all of these lifestyle
21:24 factors and I include toxins as one of them.
21:27 These are all either contributing
21:28 to your inflammatory burden or they're helping you.
21:30 And when we start thinking about optimal hormonal health and fertility,
21:35 it is your decision every single day.
21:37 Am I drinking water out of this cup or out of a plastic bottle?
21:40 Am I going to lift weights, do nothing?
21:42 Am I going to run?
21:43 How much sleep am I going to get?
21:45 What foods am I going to eat?
21:47 How do I deal with stress?
21:49 And these choices, even though one single one
21:51 is not going to make it or break it,
21:52 together they can add up to that inflammatory
21:55 burden or they can help decrease it.
21:57 And that chronic inflammation does in fact
21:59 matter to your fertility and does worry me.
22:02 I realize I'm jumping jumping around here a bit,
22:04 but um in just thinking about what seems to be on a lot of people's minds,
22:08 I took a informal poll of some people heading into this cuz
22:12 obviously I I only know my own experience as a male.
22:14 So, to a number of women,
22:18 I asked the question um you know, what what are you wondering about?
22:21 And a common question was um it seems that for some women,
22:27 if they've been pregnant once before,
22:30 uh they have it in mind that it's going to be
22:32 easy for them to get pregnant again later or easier.
22:36 And of course, they understand the logic
22:37 that they were younger before by definition, even if it's a year, right?
22:41 Um and that fertility drops off with time.
22:44 But there seems to be this um kind of belief uh that if one was pregnant before,
22:51 that it's going to be possible to get pregnant again
22:53 within the normal windows of biological windows for getting pregnant.
22:58 Is there any evidence that having been pregnant
23:01 before makes it easier to get pregnant again?
23:04 That's separate from the fact that obviously, they were pregnant before.
23:07 I realize that's a convoluted question,
23:09 but it's not a perfect experiment, right?
23:11 Because they've been pregnant before, obviously they can get pregnant.
23:13 If they haven't, the control group is not a very Yeah.
23:17 uh it it's not a good control group for an experiment.
23:20 But for within the person, if they've been pregnant before,
23:23 can they exhale a little bit that yes, they can get pregnant?
23:27 I did fellowship research with the primary investigator on a large cohort study,
23:32 one of the biggest ones we have on natural fertility,
23:34 and this study was called time to conceive.
23:36 And it was looking at women who did not have a history of infertility,
23:39 who were trying to get pregnant, who were 30 and older.
23:41 And then we looked at different variables of them.
23:44 And one of the most startling pieces of data
23:46 is that there's a huge age-related impact of fertility, right?
23:50 This data set set the standards for the numbers that we quote.
23:54 Meaning, if I will sit here and say if you're
23:55 trying to get pregnant with your first child and you're 30,
23:59 you'll have a 20% chance per month, right?
24:01 The finest point we look
24:03 at in natural fertility studies is called fecundability,
24:06 the probability of pregnancy per month.
24:08 But as you age, when you're 35 to 36, that number will be 11 to 12% per month.
24:13 At age 38, it'll be 5% per month.
24:16 And at 40 and beyond, it'll be 3% per month.
24:19 Importantly, for the person hearing this, none of those numbers are zero.
24:23 And so, by no means do we mean you can't get pregnant.
24:25 But in the group who had a child before
24:28 and were trying to conceive with the same partner,
24:30 that number stayed between 18 to 20% up till age 37.
24:34 And then it dropped.
24:36 So, we do see that there is
24:38 this protective benefit for a multitude of reasons, right?
24:41 You conceived with that person, so they had sperm, right?
24:44 Sometimes I find out some patients,
24:46 the male partner has no sperm and we didn't know all that time they were trying.
24:50 Goodness.
24:50 Right?
24:50 Oh, I've had patients try for years, be dismissed by their doctor.
24:54 Because men and women mistakenly think
24:56 that because there's semen, there's sperm.
24:58 Exactly.
24:58 There's ejaculate, so there must be sperm inside of it.
25:02 And then when we find out there's none, it's it's heartbreaking.
25:05 It's a big reason why we can segue and say one of the things
25:09 I really hate the most right now about my field is that by definition,
25:15 infertility is a failure.
25:16 And we don't even recommend testing or screening or talk
25:20 about a preventive approach at all until you have failed.
25:24 Yet if we look at the population, say okay,
25:26 the definition of infertility is trying to get pregnant for 12 months.
25:29 And then once you've reached that point, well now we'll check a semen analysis.
25:33 Now we'll do an anatomical investigation.
25:35 Now we'll check your ovarian reserve.
25:37 Now we will discuss if you're ovulating.
25:40 So, we're making you go through this period of time where you're trying and yes,
25:45 maybe the majority of people will get pregnant.
25:48 But most people who do will get pregnant the first 6 months.
25:51 So, 72% of people will get pregnant in that first 6 months of trying
25:55 and only 13% will get pregnant in the next 6 months of trying.
25:59 That's why if you're 35 and older,
26:01 we will shorten that testing interval down to 6 months.
26:04 But sitting across from so many people who've tried and tried,
26:07 went to their doctor, their doctor said, "Oh, you're fine.
26:11 You're young.
26:12 You're this, you're that." Forced them to try longer and fail.
26:15 And then to find out fallopian tubes were blocked.
26:18 They had a birth defect of the uterus.
26:20 He had no sperm.
26:21 She had low ovarian reserve.
26:23 And they would have intervened differently back
26:25 at time period A had they had that data.
26:28 Really makes me feel like we have to switch how
26:30 we approach infertility in the world where infertility rates are rising,
26:35 women are waiting later to get pregnant.
26:38 It doesn't really make sense to make people
26:40 fail first before we'll even do an investigation.
26:43 We should test things and if it's all normal,
26:45 maybe you do just go try your 6 or 12 months.
26:49 We would capture people who don't get pregnant and be
26:52 able to help them at a sooner time period, which is so valuable.
26:56 So, to your origin question, there is data that having a child previously puts
27:01 you statistically at a higher chance of getting pregnant again.
27:06 But secondary infertility is real.
27:08 This is where you've gotten pregnant before and now
27:10 you're having a hard time conceiving your second child.
27:13 I want to acknowledge that it's really hard
27:15 for people who walk it because they weren't expecting it.
27:19 They're a little underprepared for it because they said, "Oh,
27:22 I got pregnant so fast before." They come
27:24 into it just assuming it will be as easy.
27:28 They watch their children have a longer age gap,
27:30 a bigger age gap than they wanted.
27:31 But also, they don't really fit into the community.
27:33 Meaning, there's a really robust infertility
27:35 community and they support each other.
27:38 And so many patients who have secondary infertility say they feel caught
27:41 in between feeling guilty that their child's not enough for wanting more.
27:46 Of course, they're thankful for their child,
27:48 but not really fitting into that category.
27:51 Yet also simultaneously feeling left behind their friend group
27:56 or their family group or watching their family start to look differently.
28:00 And so, even in women who've had a prior child, age does become impactful.
28:04 It's not the only variable.
28:06 We also see that, you know, sperm counts change with age.
28:09 So, your partner's sperm count will change with age.
28:11 We see egg quality starts to change with age,
28:13 largely because metabolic health changes with age as well.
28:17 And then we see things like endometriosis and adenomyosis,
28:20 which are tincture of time diseases.
28:22 It's simply you've had more time,
28:24 so there's a higher probability that these diseases could be present.
28:28 So, I think it's important to say yes,
28:30 you can probably take a sigh of relief that most likely,
28:34 you won't have trouble again.
28:35 But if you've been trying those 6 months after and you're not pregnant,
28:39 I would say kind of at the longest, go and get an evaluation.
28:42 And if you're a little bit older, maybe started your journey a little bit later,
28:46 it's never too early to get an evaluation for anybody at any
28:48 time cuz you can't make decisions on data you don't know.
28:52 I'm a big fan of knowing the data and then making the choice that's right
28:55 for you and your circumstance versus taking population-based
28:59 data and just applying it to every single person.
29:02 Yeah, all excellent points.
29:03 And um with respect to the sperm testing,
29:06 since clearly there are men who think they're making sperm and they're not,
29:11 um there are at-home tests of that as well.
29:14 So, once again, men have it a little bit easier.
29:16 They can do it at home.
29:17 Although, I don't know how high quality the at-home tests are.
29:19 There are some that are just telling you,
29:21 almost like a pregnancy test, plus minus, are sperm present, are sperm not?
29:25 Of course, that's not really telling you the full picture.
29:27 There are those some mail-in tests that go
29:29 to a true lab that we would even take as valid.
29:32 So, it's a it's called a CLIA certified lab, CLIA, for somebody listening.
29:36 And you can find some of these online mail-in sperm tests and collect a sample.
29:39 They send you the whole kit, you mail it off.
29:41 It's very valid.
29:42 And you get all the sperm parameters that we would then look for.
29:45 So, that's a great way to get data yourself and not have
29:49 to have your doctor tell you no or go to a fertility clinic.
29:52 I mean, we'll do a semen analysis for anybody who calls and most clinics will.
29:56 It's usually earlier that patients are getting roadblocked,
29:59 whether it's their PCP or their regular OBGYN.
30:02 They're getting dismissed and just oh, just try first, it's probably fine.
30:06 Mhm.
30:06 You mentioned that if a woman has had a successful
30:09 pregnancy that the probability of getting
30:11 pregnant again is significantly higher, although with the caveats you mentioned.
30:15 Is there any data about if someone has
30:18 been pregnant and either terminated or lost the pregnancy,
30:21 whether or not that's related to ability to get pregnant again later?
30:24 It's a good question.
30:25 Most of the data that exists is looking at prior live birth.
30:27 So, I think there's a couple things if you've
30:30 gotten pregnant regardless of the outcome of that pregnancy,
30:33 if it's with the same partner,
30:35 we can feel confident that they had sperm present.
30:37 So, that's already one leg up over never getting pregnant.
30:41 If it was an intrauterine pregnancy,
30:43 we know at least one fallopian tube was functioning.
30:46 So, that's also in the camp of we're checking some
30:49 mental boxes of some of the things that we think about.
30:52 And we know your body could accept an embryo implanting at least to some degree.
30:55 The top cause of pregnancy loss is going to be random genetic abnormality.
31:00 This wasn't the right embryo or the embryo didn't
31:02 have the right capacity or capability to truly implant.
31:07 So, I think that should give you some sigh of relief that it's
31:10 probably going to be a little bit easier because certain boxes are checked.
31:15 I think it's also really important to say I mean,
31:17 I had four pregnancy losses myself.
31:19 I don't know if you know this.
31:19 So, I had four pregnancy losses.
31:21 Yeah.
31:21 I mean, and and by the way, could I really appreciate the personal story
31:26 uh sharing in the book because it um
31:29 it really clearly was in service to your patients and to the to the reader.
31:34 And even as a male who can't relate certainly to certain aspects
31:38 of all this, um it was it was not only very moving,
31:42 but it was it was really a testament to just how that sort
31:46 of thing lands and then the process of trying to sort out what's real.
31:50 And it just made me even more
31:51 grateful for the the other information because otherwise,
31:55 I mean, it would sort of be like if I'm talking about ovarian health, right?
31:58 Which I've I've talked about on podcast, but yeah, with all the caveats,
32:02 you know, that that how but of course, how could I possibly know?
32:05 So, the your personal experience well the reader and I,
32:09 you know, feel feel and felt for you in in reading it.
32:12 It is it is super impactful because people there's a level
32:15 of trust that just comes from somebody who's been through that whole jungle.
32:18 Thank you.
32:20 I'll try not to cry on this show about it,
32:21 which is funny cuz it's so long ago, right?
32:23 I have two children now.
32:25 Had them after this journey.
32:27 And it was terrible for so many different reasons.
32:31 Of course, going through pregnancy loss is an emotional roller coaster.
32:35 I started to have a lot of self-blame against myself.
32:38 I felt like it was my own body, something was wrong.
32:41 And professionally, what I was unprepared for is I was This was
32:46 the end of OBGYN and then
32:47 the beginning of my reproductive endocrinology fellowship.
32:50 So, I felt like how am I going to be a fertility doctor,
32:54 Andrew, if I can't even get myself pregnant?
32:56 Right?
32:56 The professional impact of how it made me view myself and my space,
33:02 I was so unprepared for, right?
33:04 We especially in an era where you separate your personal and professional life,
33:08 which is, you know, what was 100% accepted back then.
33:12 You know, my last pregnancy loss was an ectopic pregnancy.
33:14 My fertility nurse had to give me my methotrexate shot.
33:17 I mean, everybody knew about it.
33:20 And I felt like a really big failure.
33:23 And when I sought help to say it'll happen, just relax,
33:27 there's nothing you can do or even just do IVF,
33:31 felt so dismissive of what I felt like was true as the patient experience.
33:37 Say, well, what about this symptom or what about this question?
33:40 And just really, really pushed aside.
33:41 And I'll be honest, it made my whole career is different because of it,
33:46 which isn't it interesting how sometimes things happen to us that are not ideal.
33:51 And that can be really terrible.
33:52 I have the two kids I'm meant to have,
33:55 but also I have forever viewed fertility differently.
33:58 In fact, all my fellowship research was on natural
34:01 fertility because of it cuz I said at the core, I want to know why some people
34:05 get pregnant naturally and why other people don't.
34:07 Like I really want to know that.
34:09 I want to do epidemiologic research.
34:11 I got a master's in clinical research
34:12 because that research is very complicated to understand.
34:16 And most fellows do an IVF lab project, which is great,
34:19 but it's a lot more of a controlled environment.
34:22 And then I've been so passionate about talking about it since then.
34:25 And so, I think to walk back what I wanted
34:28 to say though is if you've gone through pregnancy loss,
34:30 I don't want to ever dismiss how terrible that experience is.
34:34 And sometimes it can feel that way by me
34:36 sitting here as a professional and saying oh,
34:39 you had a pregnancy loss, so that could be a good sign for the future.
34:42 Mhm.
34:42 And I don't want anybody to ever feel that hearing it,
34:45 but it does tell us that certain systems are intact.
34:48 On the other hand, after two pregnancy losses, you need an evaluation.
34:52 The evaluation is for certain blood tests, a semen analysis,
34:56 a sperm fragmentation, and a uterine and tubal evaluation.
35:00 That can be moved up to one if you had heavy blood loss,
35:05 you know, needed a D&C procedure, if your periods have changed afterward,
35:09 if anything was really off, you can always get tested.
35:13 And we never want to be in the world where we used
35:15 to make women go through three pregnancy
35:17 losses before they would get an evaluation.
35:19 And I fell into that camp.
35:20 After two, I said, shouldn't we do tests?
35:24 I'm starting to fall off the curve here.
35:25 Isn't something wrong?
35:27 And I was told, you need to have
35:28 another pregnancy loss before we'll do those tests.
35:31 And that's the worst thing,
35:32 the worst feeling that I had to fail again to a certain
35:36 degree and lose a pregnancy before they would even investigate why.
35:40 Yeah, that this theme it seems of like it's only
35:44 menopause when you haven't had a period for a year,
35:46 you have to have two pregnancy losses and then
35:47 we can put you into this category of like oh,
35:50 amenable for treatment.
35:52 I mean, it's so it's um something really backwards about all of that.
35:56 I imagine with your book and um you being public facing with health information
36:00 and hopefully others um with you in your field that eventually this will change.
36:05 I mean, I if I were to draw the parallel to psychiatry, which isn't a fair one.
36:08 I mean, should someone really have to um be waking
36:11 up at 3:00 in the morning for an entire year
36:13 and have no uh hope for the future and be
36:16 near suicidal before they get whatever the adequate treatment is?
36:20 or whatever is going on.
36:21 It doesn't [clears throat] it doesn't make sense.
36:23 I don't think it serves us.
36:25 And I will say this, too.
36:26 And we're starting to see a change.
36:29 My big lofty hope for the book is that it changes the entire field of fertility.
36:34 Like I understand why OBGYN used to take care of this.
36:38 And then at some point they said, some people have infertility,
36:41 let's draw a line in the sand and have some people specialize in this, right?
36:45 And I had 3 years of training in that after OBGYN.
36:49 But at the same point, it doesn't make sense to practice that way.
36:53 It doesn't make sense to force people to fail.
36:56 And I might tell you, hey,
36:57 the greatest likelihood is all the tests will come back normal.
37:00 But we should do them because sometimes it doesn't, right?
37:04 If I look across somebody who has recurrent pregnancy loss,
37:06 I say, 80% of the time, every test will come back normal.
37:09 But 20% is is a big number.
37:12 That's a lot of people who maybe it's a simple medication,
37:16 maybe it's a procedure,
37:17 something can markedly change what they're going through.
37:21 And in the same breath,
37:22 and the 80% really need specialized care because what's really
37:26 going on if we don't have an easy test for it.
37:29 So, I agree with you.
37:29 I think the whole field needs to change.
37:31 I think we need change how we define terms, how we address women,
37:35 how we approach reproductive health and hormones and fertility.
37:38 And really in a more proactive patient-centric approach.
37:42 And women and men are driving this really by talking about it.
37:46 10 years ago when I started on social media, nobody talked about fertility.
37:50 And patients who did had nameless, faceless accounts.
37:54 And now you see celebrities talking about IVF, talking about endometriosis,
37:59 talking about their termination for genetic reasons or whatever happened.
38:04 And those stories are so powerful to drop the stigma,
38:08 but also highlight how wrong it is that we force women
38:11 to fail before we'll even evaluate what's going on, let alone treat.
38:17 As many of you know, I've been taking AG1 for nearly 15 years now.
38:21 I discovered it way back in 2012, long before I ever had a podcast,
38:25 and I've been taking it every day since.
38:27 The reason I started taking it and the reason I still take it is because AG1 is
38:31 to my knowledge the highest quality and most
38:33 comprehensive of the foundational nutritional supplements on the market.
38:37 It combines vitamins, minerals, prebiotics, probiotics,
38:41 and adaptogens into a single scoop that's easy to drink and it tastes great.
38:45 It's designed to support things like gut health,
38:48 immune health, and overall energy.
38:50 And it does so by helping to fill
38:52 any gaps you might have in your daily nutrition.
38:54 Now, of course, everyone should strive to eat nutritious whole foods.
38:57 I certainly do that every day.
38:59 But I'm often asked if you could take just one supplement,
39:01 what would that supplement be?
39:03 And my answer is always AG1 because it has just been
39:06 oh so critical to supporting all aspects of my physical health,
39:09 mental health, and performance.
39:11 I know this from my own experience with AG1,
39:13 and I continually hear this from other people who use AG1 daily.
39:17 If you would like to try AG1,
39:19 you can go to drinkag1.com/huberman to get a special offer.
39:24 For a limited time, AG1 is giving away six free travel
39:27 packs of AG1 and a bottle of vitamin D3K2 with your subscription.
39:31 Again, that's drinkag1 with the numeral one.com/huberman to get six free
39:36 travel packs and a bottle of vitamin D3K2 with your subscription.
39:41 One theme that I heard over and over again was um women would say, "Okay,
39:49 they thought that they might have been pregnant before
39:51 or they knew they had been pregnant once before." Circumstances varied,
39:55 but they sort of had it in mind that they could get pregnant at some point.
39:58 And that their mom had one either them or a sibling let's
40:04 say at like age 42 or 43 and they're in good health themselves.
40:10 And so they had it have in mind that there's time.
40:14 I think this is not uncommon.
40:17 And given that life is very expensive,
40:20 most people in the world seem to be underpaid nowadays.
40:23 And people are waiting longer to get married and have children.
40:28 And the other common narrative that I was
40:32 hearing was that there people that want kids, but they it's under the well,
40:36 if I found the right person, I would do it,
40:38 but otherwise I wouldn't do it on my Yeah.
40:40 That's not always the case,
40:41 but it's it's pretty it's a it's a it's a common theme, right?
40:45 So for those women, which I think is quite a few,
40:48 whether or not they're in their 20s or their 30s or their 40s,
40:52 what sorts of things do you recommend they would
40:54 add to that rather just kind of real life analysis?
40:57 Those are not meaningless metrics like how would
41:00 one's mother had a a child or for instance.
41:03 But things have changed.
41:05 Microplastics, maybe certain things have gotten better, right?
41:07 We're no longer eating margarine.
41:08 I'm I'm not trying to be facetious Yeah.
41:10 here.
41:10 I think that there's so many variables.
41:12 People are living longer, yet there are more environmental toxins perhaps.
41:16 I mean people are smoking less.
41:17 So it the Are they though?
41:19 Are they?
41:20 We'll talk about nicotine for sure.
41:22 So for those women in their let's say 20s, 30s, and early 40s Yeah.
41:29 What's the level of urgency that they get certain
41:32 things checked out and what should they get checked out?
41:34 Oh, and I should say that they'll say that they're having regular periods.
41:38 I'd love to answer it and I'm going
41:39 to, but for the person who's maybe coming to this discussion let me
41:44 let's explain egg quality really quickly cuz it really is going
41:46 to tie into what we can test and what we cannot.
41:49 As you know well, women are born with all the eggs they're ever going to have.
41:52 The eggs are kept I like to think about it
41:54 as in a vault inside your ovary and so they're stored there.
41:57 You have the most eggs when you're 5 months old inside your mom.
42:00 You have 6 to 7 million eggs.
42:02 By the time that you're born, you have 1 to 2 million.
42:04 By the time you start your first period, you have half a million.
42:07 So you lose eggs over time.
42:09 A lot of the determination of that starting number will be influenced some
42:13 by genetics and some from your mom's health while she's pregnant with you.
42:16 Things she's exposed to, her current disease state.
42:19 What I want people to think about is every single month you are losing eggs.
42:23 So I like to imagine and describe to my patients
42:25 a group of eggs is coming out of the vault.
42:27 Each egg grows inside a small fluid-filled structure called a follicle.
42:30 The brain sends out follicle-stimulating hormone or FSH,
42:34 well-named, gets a follicle to grow.
42:36 As the follicle grows, it makes estrogen.
42:38 This is called the follicular phase.
42:40 Estrogen levels talk back to the brain.
42:42 Remember that the brain does not see what's happening anywhere in the body.
42:46 It is simply waiting for the hormone signal.
42:48 That's what hormones are.
42:50 They're communication signals.
42:51 I like to think about it like text messages between friends.
42:54 When estrogen is high enough for long enough,
42:56 200 picograms for 50 hours and that's the level
43:00 it'll tell the brain it's time to ovulate.
43:02 The brain will send out a surge of LH.
43:05 Follicle will then rupture.
43:06 Egg will be released.
43:08 It only has 24 hours to be fertilized,
43:10 but that follicle will actually reform and become the corpus luteum.
43:14 Now we're entering to the back half of the cycle called the luteal phase.
43:17 The corpus luteum makes progesterone stimulated from LH pulses from the brain.
43:22 So then it makes progesterone pulses throughout the luteal phase.
43:26 Can only live for about 2 weeks unless a pregnancy occurs.
43:30 When you have an embryo come in and implant,
43:32 it makes HCG, the pregnancy hormone we check in a pregnancy test.
43:36 Fun nerdy fact, HCG and LH share a receptor.
43:39 So HCG comes into the corpus luteum
43:41 and now stimulates a constant production of progesterone.
43:44 But if that doesn't happen, corpus luteum will die,
43:47 progesterone will drop, and you'll get a period.
43:50 Okay.
43:51 Also back to the vault, you have a different number of eggs that come
43:54 out every month that is proportional to how many remain.
43:57 So when you are younger, when you have more eggs,
44:00 more eggs come out of the vault every month.
44:02 As you get older and you have fewer eggs, fewer come out every month.
44:06 That explains why you go from 6 to 7 million to 1 to 2 million and why
44:10 you go from 1 to 2 million to half
44:11 a million because you had more, you're losing more.
44:15 At some point everybody will be out of eggs, right?
44:18 We're going to call that ovarian failure
44:20 and not menopause for the sake of our discussion,
44:22 but so everybody will go into ovarian failure.
44:25 Now the timeline once you have your your clock is now up.
44:29 Because at that point there's no more eggs,
44:30 you cannot get pregnant with your own genetic child.
44:34 You still have a functioning uterus.
44:36 It's just not being stimulated.
44:38 So importantly, those women can get pregnant with donor eggs or donor embryos.
44:42 They can still carry a pregnancy.
44:44 That's sometime a myth that people think about.
44:47 But once you're out of eggs, that's kind of the end of your clock.
44:50 Now two things are happening with time
44:53 that are really important because your eggs are inside
44:55 that vault inside your ovary is that they absorb the wear and tear of your life.
45:00 And your egg has many different functions.
45:02 It has to respond to hormone signals and make estrogen,
45:06 make progesterone, and ovulate.
45:08 The mitochondria inside the egg, which everybody knows the mitochondria,
45:11 the powerhouse of the cell, gets exclusively passed on to the embryo.
45:15 It completely controls embryo growth and development.
45:19 In fact, the male genome doesn't even
45:20 kick in until day three after fertilization.
45:22 All those first few days are 100% maternal.
45:26 The egg also has a hold the chromosomes in correct position.
45:30 So an interesting fact is that inside the egg,
45:32 it is frozen in metaphase of meiosis two for whatever reason.
45:37 And so the chromosomes have met in the middle and they're held
45:39 apart by those meiotic spindles and they do not separate until you ovulate.
45:43 And so then you get your egg that has all we think about as your 23 X.
45:47 The other part goes into a polar body.
45:50 Okay, this means that when you're 25,
45:52 your eggs have only been held in metaphase for 25 years.
45:55 Your chromosomes are for the most part still in the right position.
45:58 Your proteins are strong that are holding them apart.
46:01 Most people have better generalized metabolic health.
46:04 Their mitochondria are stronger.
46:06 When you are 40 40 years have passed.
46:10 We've asked those chromosomes to hold there longer.
46:12 And we say if I have a line of kindergarteners
46:14 and I ask them to stand for 40 years, like somebody's going to get out of line.
46:17 So tincture of time adds up.
46:19 But the other thing that happens as we get older is as a population,
46:22 we get more metabolically unhealthy.
46:24 So we see more chronic inflammation, more insulin resistance, more obesity.
46:29 And all of those factors influence oxidative stress,
46:32 mitochondrial health, DNA damage.
46:35 They can damage the meiotic spindles holding those chromosomes apart.
46:39 So we also see more genetic abnormalities as we age,
46:43 but that is worsening as metabolic health worsens, too.
46:47 Okay.
46:48 We don't have a direct test for egg quality.
46:50 That's what we call egg quality.
46:52 Genetic normalcy and egg competency.
46:54 How good are the mitochondria?
46:56 Can it do its job?
46:58 We approximate it to age.
47:00 Which has some faults because not all 40-year-olds are created equal.
47:04 When we think about ovarian reserve, this is how many eggs you have remaining.
47:08 So this is how many eggs are inside the vault.
47:11 And we can approximate it with a blood test called AMH.
47:14 AMH stands for anti-Müllerian hormone.
47:16 It's made from the granulosa cells that surround each follicle.
47:19 So in its purest form, more eggs inside the vault, more come out, more AMH.
47:25 Fewer eggs in the vault, fewer come out, lower AMH.
47:28 Not a perfect test.
47:29 The vault also is not perfect,
47:31 so there's some month-to-month variability in how many exactly get sent out.
47:35 And in prolonged periods of not ovulating, AMH can be suppressed,
47:40 whether it's from birth control pills,
47:41 pregnancy, postpartum, whatever the reason is.
47:44 So AMH is imperfect, but it is something and it's a very simple blood test.
47:49 It's not telling us if you can get pregnant or not,
47:52 but it is telling us how many eggs do we have outside the vault.
47:56 And the way I like to frame this is that every woman who wants
48:00 to have children or understand her own
48:02 reproductive timeline should get an AMH checked.
48:06 That is against medical advice,
48:08 meaning the American College of OBGYN says that women
48:11 should not get an AMH checked unless they have infertility.
48:14 Okay, this is wild to me, right?
48:16 I mean to me as well.
48:17 I mean it just seems like like this failure criteria
48:21 it just seems so it seems just very extreme and unnecessary.
48:26 Unless there's some hidden agenda to try
48:28 and prevent people from maintaining fertility
48:30 or having children because and that doesn't square with at least my assumptions.
48:36 The idea here is that it can be really stressful.
48:39 This is what they say in their document.
48:40 American College of OBGYN,
48:41 it can be very stressful for a woman to find out
48:43 she has a low AMH and that it doesn't predict fertility.
48:48 And there's some truth to that.
48:49 So let's think about I have two 30-year-olds.
48:52 One has 20 eggs outside the vault, which would be age-related norm,
48:56 and one has five eggs outside the vault.
48:58 Well, if every single other factor is
49:00 the same and they each are ovulating one egg,
49:03 they have the same chance of getting pregnant, right?
49:05 So that's not a faulty statement.
49:08 However, the person who has five eggs will not have as long to grow her family.
49:12 She will not get as many eggs if we're doing advanced treatment like egg
49:16 freezing or IVF because I can only get the eggs outside the vault to grow.
49:20 So it's hugely impactful for what your journey may look like in treatment.
49:24 But more so than that, Andrew,
49:26 so many of the causes of a low AMH directly contribute to infertility.
49:31 Things like autoimmune disease,
49:33 insulin resistance, endometriosis, smoking cigarettes.
49:37 So if there are factors, some of which you can control,
49:40 some of which you can treat.
49:43 If I have a woman who has a low AMH,
49:46 I'm not going to sit here and say, "Okay, well, you can still get pregnant,
49:48 no worries." I'm going to say, "I don't know that you'll have infertility,
49:51 but some of the reasons your AMH is low can cause infertility.
49:55 You will get fewer eggs if we're freezing your eggs or doing IVF.
49:58 You will go into menopause earlier.
50:00 So, we need not wait, right?
50:02 To your point, the woman who's 20, 30,
50:04 40 thinking about this, she might make a very different decision when
50:09 she knows she's really faced with a timeline that is less than ideal.
50:14 And why should we allow time to be making that decision
50:17 for us instead of at least playing an active role?
50:20 I sit across from women every day find out they have a low AMH,
50:22 and I say this, like, let's do the investigation to see if we can find out why.
50:26 Probably 50% of the time we find an autoimmune disease.
50:30 I can't reverse the clock, but I can slow down the rate of inflammation, right?
50:34 If say [clears throat] if it's Hashimoto's,
50:36 suddenly we can do thyroid replacement, we can work on decreasing inflammation.
50:39 If inflammation harms our ovary, maybe we can slow down that rate of egg loss.
50:45 At least she's being treated and probably feeling better
50:47 and will have improved fertility outcomes because her Hashimoto's is treated.
50:50 So, we should look at why.
50:51 Why is it low?
50:53 And treating that why very well may impact fertility.
50:56 We also might say, what should we do about this?
50:58 You know, I have a lot of couples who are partnered
51:01 who are just waiting for the right time to get pregnant.
51:04 So, sometimes we say, well, we could get pregnant, but I'm in medical training,
51:09 I'm going to law school, I'm doing XYZ, it's not a good time.
51:13 Well, when faced with their perfect time, they may not have eggs anymore.
51:17 Suddenly, we reevaluate where we are, and there's no one right answer.
51:21 We might choose to try to get pregnant now.
51:23 If we don't have a partner, we might buy donor sperm and try to get pregnant.
51:26 Maybe we freeze eggs.
51:28 Maybe we freeze embryos.
51:29 Maybe we do none of those things, but we made the active choice, right?
51:33 Sitting here saying,
51:34 "I chose not to pursue treatment knowing my AMH was low and that I might
51:39 be in ovarian failure at the point when I was planning to have a family,
51:43 and I know that" makes the journey so much easier to walk because you made
51:47 that active choice from a place of a knowledge
51:49 that was your autonomous decision versus saying,
51:53 "I asked my doctor for an AMH test 5 years ago.
51:56 They told me it wasn't medically recommended because I don't have infertility,
52:00 and had I known that information then,
52:01 I might have done something different." Well,
52:04 that was the longest discussion to say everybody should get an AMH.
52:07 I think it's a very important marker.
52:09 It's a newer-ish test.
52:11 We've only been checking it for about the past 10 years.
52:14 It's not a perfect test.
52:15 I don't have the nomogram for exactly how it should drop over time,
52:19 and I like to think about it as categories.
52:21 Normal, above average, below average, critically low.
52:25 And based on your category, we should probably talk and do different things.
52:29 If you are listening to this and you want kids one day,
52:32 ask your doctor for this test.
52:34 If they say no, you can order it yourself at a LabCorp request,
52:38 many of the online platforms like Function Health,
52:41 you can have an AMH checked through them.
52:43 You can ask your doctor for it and say, "Well, if it's low,
52:46 I know I'll talk to a fertility doctor to find out more
52:49 information." Or call a fertility clinic
52:51 and just say you want fertility testing.
52:53 The end.
52:54 Okay, I think it's such an important [clears throat] marker.
52:56 It is not a test of egg quality.
52:58 You know, we talked about what egg quality is, right?
53:00 Genetics and egg competency, but it is a check of how many eggs you have,
53:05 and that knowledge can be really impactful
53:08 for how you view your future and your plan.
53:10 So, I think everybody should get an AMH.
53:12 I think we've got to learn to track our cycle,
53:14 and I know you said in the vignette that these women have regular cycles.
53:20 Having a regular period is really good.
53:22 It's much better than having an irregular period,
53:25 but knowing when you ovulate and tracking ovulation is a much more sensitive
53:30 health marker than simply when you bleed or when you have a period.
53:34 Because tracking ovulation is going to allow us to know how
53:37 long is your luteal phase and how long is your follicular phase.
53:41 And ovulation disorders progress through a very predictable pattern,
53:45 and we know this well.
53:47 The first stage of an ovulation disorder is a luteal phase defect,
53:51 meaning a shortening of your luteal phase.
53:53 So, you're ovulating, but the brain and ovary have a miscommunication,
53:58 and we don't make progesterone long enough to sustain the luteal phase.
54:02 Less than 11 days is a short luteal phase, but you'll still have regular cycles.
54:07 So, if I sit across from somebody and I just say,
54:09 "Are your cycles regular?" and they say yes,
54:12 and we carry on, I've missed the fact
54:14 that they actually have a shortened luteal phase,
54:17 and that warrants further investigation.
54:19 Prolactin, thyroid, AMH, PCOS, looking at different causes.
54:25 The second stage of ovulation disorder is a long luteal phase.
54:29 Takes the ovary longer to actually respond to the FSH stimulus from the brain,
54:35 and then from there we'll progress into irregularity
54:38 and true amenorrhea or absence of periods, but those first stages,
54:43 you might miss the little red flag warning sign that something's
54:47 wrong inside your body because you're just tracking when your bleed is,
54:50 and it's every 34 days, so you think it's normal,
54:54 but if we were looking at when you actually ovulated, we have more data.
54:58 So, learning to track ovulation as opposed to just cycle tracking,
55:03 I think is one of the most important skills a woman
55:05 can have for learning to listen to her own hormonal cues.
55:11 Amazing.
55:12 Um just I don't say that lightly.
55:14 You just explained egg quality, the biology of the of the ovulation cycle,
55:19 and how it links to the actionables, and um I'm just struck.
55:22 It's awesome.
55:24 Um And it has me asking a couple of practical questions.
55:29 Um some people will have insurance, some won't.
55:31 What's the cost of an AMH test?
55:33 Let's assume insurance doesn't cover it.
55:36 Um and they just have to go completely out of pocket.
55:38 Uh and before you answer, I will say whatever it is,
55:41 I think it should probably be compared against what it would
55:44 be to try and um I don't want to say rescue,
55:47 but but to not take the test, and then,
55:50 you know, 3 years later you're trying to harvest eggs.
55:52 It could be multiple cycles because you you
55:54 realize it was only five eggs per you know,
55:57 per month as opposed to age match, right?
56:00 15, right?
56:00 Exactly.
56:01 So, um so, are we talking hundreds of dollars, thousands?
56:05 $79.
56:07 a $79 test, and I I feel really strongly about this.
56:13 I do not view myself as the gatekeeper of information about your body.
56:17 Do you want hormone levels checked?
56:18 Do you want an AMH?
56:19 I do not think that is the role of a physician.
56:21 I know I can say your insurance doesn't cover it.
56:24 You can make the decision if $79 is worth it to you,
56:27 but in the age of information,
56:29 where that's an easy test to do, every lab runs it,
56:32 and it's relatively inexpensive compared to freezing your eggs or IVF.
56:37 I mean, right?
56:38 Multitudes.
56:39 $79.
56:39 We're throwing a fit over a $79 test.
56:43 Wow.
56:44 Um [cough and clears throat]
56:46 I I'm going to make sure that message goes far and wide.
56:49 Um because I you know,
56:49 I thought you were going to say maybe in the high hundreds or thousands,
56:52 which for some people is going to be, you know, prohibitively expensive.
56:55 Yes, I So, get AMH checked.
56:57 I think I'll avoid going into too
56:59 much editorializing here because I'm really just interested
57:01 in in how you view this, but how you describe the the sort of the the way
57:06 your field has a originated and where it's headed reminds me a little bit
57:11 of I remember in the '80s there was
57:12 a genetic testing was starting to become possible.
57:16 And a lot of it was happening at Stanford.
57:17 I happen to grow up near campus,
57:18 and I remember hearing you could get tested for like Huntington's disease,
57:21 which is it can be a devastating disease.
57:24 Um and the idea was people don't want to know.
57:27 People don't want to know.
57:28 I think everything I've I've observed, I can't speak for everyone,
57:31 but everything I've observed about people's interest
57:34 in their own health and genetics and what
57:37 genetics does and doesn't mean tells me
57:39 that people are actually much more interested,
57:43 and they're much smarter than let's just call it the traditional medical field,
57:47 certainly medical genetic testing, gave them credit for.
57:51 It's like people aren't idiots.
57:52 You can sit someone down and say, "Hey, listen, you have this gene.
57:55 There's an X probability.
57:56 Here's the things you can do to protect yourself." And but there
57:59 was this assumption like people don't want to know because now they're going
58:01 to live in dread and their life is going to be destroyed
58:04 if they know they're going to get
58:05 full-blown Huntington's or something like that.
58:07 It's so paternalistic.
58:08 It's actually I mean, it borders on unethical.
58:12 Um people are smart.
58:13 People can take in information,
58:15 and they can make decisions that don't necessarily
58:17 crater them on the basis of just knowledge.
58:20 I mean, it feels like we sort of treat people like children,
58:23 like little children.
58:24 And even little children would probably want to know certain things.
58:27 Although you don't want to give them genetic information,
58:29 but certain things like, "Hey, you have a challenge with X, Y, and Z,
58:33 and you can overcome it in the following ways." Technology's advanced.
58:37 It has.
58:37 How we counsel and how we approach health care needs to advance also,
58:42 meaning we don't live in a universal health care system.
58:45 We don't have only X dollars to spend on every single patient.
58:48 And in certain circumstances,
58:49 when that's the case or a patient has limited money,
58:51 we do have to make very judicious decisions about the best use of those dollars.
58:57 But for the majority of people who will be listening
58:59 to this, they are willing to spend money on their health,
59:03 and it shouldn't be a society or a physician or somebody standing
59:06 in the way of getting data that can dramatically impact your life.
59:10 And because you mentioned Huntington's, I should say, right?
59:13 Autosomal dominant disorder.
59:14 People have very strong feelings on if they want to know they have it or not,
59:17 and I've had patients because we can test for this with IVF.
59:21 So, we do genetic testing of embryos,
59:23 and we often do screening to see if the chromosomes are in the right position,
59:27 which we talked about for age, that can be really beneficial.
59:30 We can do single gene testing as well,
59:32 PGT-M for monogenetic diseases and Huntington's is one of them.
59:36 And I've had some patients say, I my mom had Huntington's.
59:41 It was the worst experience to watch her go through that.
59:43 I would love to test my embryos,
59:45 but I I've committed to myself that I don't want to know if I have it or not.
59:49 Okay?
59:50 And I think it's really important just to mention that disease to say,
59:53 we can blind test you.
59:55 You you know, we can you can make a probe to see if you carry it or not.
59:59 You don't have to know and we can still test the embryos.
1:00:02 And I've had a few patients who then themselves did not want to know,
1:00:05 but we went through the steps to make a probe in case they did.
1:00:08 In both cases, the patient did carry it, didn't find out that they did,
1:00:12 but they could assuredly transfer an embryo
1:00:14 that did not have it because often they
1:00:16 these people have felt so strongly watching
1:00:19 a family member die from a terrible progressive disease.
1:00:22 They've said children are not in the cards for me.
1:00:26 Or I'm not going to have genetic kids.
1:00:27 Or sometimes they'll come to me saying,
1:00:29 we have to use an egg donor or sperm donor
1:00:31 because I might carry this and don't want to know.
1:00:34 So, again, it's the idea that that should be
1:00:37 your own individual choice whether you want to know or not,
1:00:40 but it shouldn't be the society or somebody else putting this roadblock up.
1:00:44 And it's such an antiquated approach in the era of technology
1:00:48 and access where you really can get so many data points.
1:00:53 Why should somebody be making the decision
1:00:55 on if that information's valuable to you?
1:00:57 Yeah, and I think with blood testing, the price coming down, um,
1:01:01 it seems to me maybe it's just the circles I
1:01:03 run in that people want more information as opposed to less.
1:01:05 But I'm glad that you raised this um these cases
1:01:08 where people don't want to know certain certain amounts of information.
1:01:12 Um one thing that well, I'll just pose this as a question.
1:01:17 How many women out there,
1:01:19 um do you think know if I'll have to be careful how I word this.
1:01:26 If doing a egg harvest cycle um decreases their ovarian reserve or not.
1:01:33 The majority of patients that I sit across from will tell me,
1:01:38 I'm afraid to freeze my eggs or do IVF
1:01:40 because I don't want to go into menopause earlier.
1:01:43 So, the myth that doing that is going to tap into the vault and pull out
1:01:48 eggs is inaccurate and a fear that really
1:01:51 does need to be busted because it doesn't.
1:01:54 It's a limitation of the science that I can
1:01:56 only get the eggs outside the vault to grow.
1:01:58 If I could tap into the vault, it would change the game.
1:02:01 But right now I am limited by the eggs you give me,
1:02:05 the number of them controlled by whatever's outside the vault.
1:02:08 We in IVF, we just give FSH, same hormone your brain makes,
1:02:11 trying to stimulate more than one egg to grow.
1:02:14 Your body doesn't want to have five kids or 12 kids or 20 kids,
1:02:18 so it has checks and balances to prevent that from happening.
1:02:21 I, however, would like every egg outside the vault to grow because in nature,
1:02:25 you will ovulate one and everything else will die.
1:02:28 You are constantly losing eggs no matter what.
1:02:32 When you're pregnant, when you're breastfeeding, when you're on birth control,
1:02:34 before you start your first period, constantly losing them.
1:02:38 I cannot change that right now.
1:02:40 So, doing IVF or egg freezing is not going to decrease your ovarian reserve.
1:02:44 It is simply going to influence one month
1:02:46 in time trying to not have all those eggs die.
1:02:49 And I think the myth is that um by doing a cycle
1:02:53 of of egg freezing that you're taking more eggs from your reserve.
1:02:58 Um but as you pointed out, women are losing the same number of eggs
1:03:01 each month or follicles each month regardless.
1:03:04 You're maximizing on that process by just maturing more
1:03:08 and taking them as opposed to letting them die.
1:03:11 Exactly.
1:03:11 We are not running out of eggs early.
1:03:14 I think it's just based on again, nobody understands basic biology,
1:03:17 so we think in our brain, I'm just losing that one egg since I'm ovulating.
1:03:21 We're not thinking about all of the ones
1:03:23 that were sent out of the vault who weren't chosen.
1:03:26 Yeah, and [clears throat] I think people will also assume um because
1:03:28 they haven't been told that if you do an egg, you know,
1:03:32 if you stimulate for more to mature that you're somehow
1:03:35 um taking away from eggs that you would have had,
1:03:38 you know, stuck around somehow.
1:03:40 Uh so, we're we're hitting we're at you
1:03:41 we're saying the same thing three different ways.
1:03:43 you're giving I mean, it's fascinating to me if you think
1:03:46 about it because we are allowing the possibility
1:03:48 for you to have children in your family that likely you would not, right?
1:03:53 Because if you were to get pregnant naturally that month,
1:03:55 the greatest probability is it would just be one that you would ovulate.
1:03:58 Yeah, for IVF, we can sometimes take one month's
1:04:01 group of eggs in time and have a couple
1:04:03 different embryos and those become a couple children
1:04:05 for you that you have from this one exact cohort.
1:04:08 I think it's so fascinating.
1:04:10 You know, early IVF days, I mean, IVF is not that old.
1:04:14 It's only been around like 46 years.
1:04:16 I think the oldest IVF babies we didn't have gonadotropins.
1:04:20 We didn't have FSH um that was, you know, synthetic or purified.
1:04:24 And so, we couldn't get multiple eggs to grow.
1:04:26 So, original IVF patients had to go live
1:04:30 at their IVF clinic and they had urinary-based
1:04:33 hormone measurements done every day so they could
1:04:36 try to gauge when as estradiol was rising,
1:04:39 when they were getting closer to ovulation.
1:04:42 And in those days, this is just science,
1:04:44 they went and they did abdominal surgery to aspirate the egg.
1:04:46 Now we do a vaginal egg retrieval where
1:04:48 we take a needle attached to a vaginal ultrasound.
1:04:50 It's a minimally invasive procedure.
1:04:52 But back in the origin IVF studies,
1:04:54 they had to go and do an abdominal incision to put a needle
1:04:57 in the one single follicle to get the follicular fluid and the egg out.
1:05:01 So, it was very low odds of working.
1:05:04 It was crazy to even think of, but the advent of gonadotropins,
1:05:08 the ability to it first started by purifying FSH and LH and be
1:05:12 able to give that to people to stimulate more than one egg,
1:05:15 understanding this concept that there's so many more
1:05:17 eggs that you have outside the vault every month,
1:05:20 that has changed the game and is such an amazing advancement
1:05:23 in science that we can leverage that physiology for egg freezing or IVF.
1:05:29 Uh very practical uh question.
1:05:32 Um it's clear that the younger that a woman is,
1:05:35 the the more eggs that uh could be uh frozen in a given cycle.
1:05:39 But I think it's fair to say that many people,
1:05:42 either because of finances or life circumstances,
1:05:46 that could be not having a partner and wanting a partner before having kids,
1:05:49 this sort of thing, um are waiting.
1:05:52 They're just waiting.
1:05:53 What stands between um us now in the United
1:05:58 States and egg freezing being covered by insurance 100%.
1:06:04 I don't hold any superpowers, but there are, you know,
1:06:06 there are pretty powerful ways to lobby um all the administrations
1:06:11 regardless of who happens to be in office when that actually happens.
1:06:13 I mean, it is possible, right?
1:06:15 That the the phone is a powerful tool.
1:06:17 Advocacy is a powerful tool.
1:06:18 I do think that um things can happen um if there's a lot of advocacy.
1:06:24 So, um first question is, you know, what would that require?
1:06:29 And um is that a good idea?
1:06:32 I am a fan of knowledge and options.
1:06:34 And egg freezing is not a guarantee.
1:06:35 So, you know, how I pose it to patients is,
1:06:38 we are going to keep the door of opportunity open longer for you.
1:06:41 And that is our goal.
1:06:42 If we want to compartmentalize it as some
1:06:45 people will falsely sit across from me and say,
1:06:47 oh, egg freezing's an insurance policy for my fertility.
1:06:51 And it's not cuz an insurance policy always pays off,
1:06:54 but it's an investment in my fertility.
1:06:56 Like investing in the stock market.
1:06:57 Like probably will pay off,
1:06:59 but it depends on external factors that we don't have yet, right?
1:07:02 So, the ROI is yet to be determined,
1:07:04 but in general considered to be a good thing.
1:07:08 I think it would be absolutely incredible to be
1:07:10 in a place where egg freezing could be covered.
1:07:12 And you know, there's definitely countries where it is.
1:07:15 That they have said with the birth rate is dropping,
1:07:17 we want to keep the reproductive lifespan open for some patients.
1:07:21 We want to offer this.
1:07:22 I think to be honest and transparent,
1:07:25 the number one restriction against that that we see as a field right now is
1:07:30 the camp of people who are ethically or morally
1:07:32 opposed to IVF for reasons of embryo disposition.
1:07:38 [clears throat] Embryo disposition.
1:07:39 the personhood of an embryo.
1:07:40 Is an embryo a person?
1:07:42 I see because embryos that are not used
1:07:45 are going to be either kept frozen or discarded.
1:07:47 And to those people, that's seen as essentially killing a baby.
1:07:51 Correct.
1:07:52 Right, that's their that's their view.
1:07:53 Yeah, and and we should acknowledge that.
1:07:55 I have many patients right now who are donating embryos,
1:07:57 you know, when they are done with their family,
1:07:58 which is an amazing way to kind of pass forward
1:08:02 the opportunity and for other couples to have a family.
1:08:06 And I also just want to say at the top of this is that IVF is incredible.
1:08:10 17 million babies have been born in this world because of IVF.
1:08:14 So, I think this technology's great.
1:08:16 Does that mean everybody has to do IVF?
1:08:17 No.
1:08:18 You are allowed to have your own feelings
1:08:21 and decisions about anything that you do, IVF included.
1:08:25 And there's often things we can do within
1:08:27 the procedure for patients who might have religious or ethical
1:08:31 concerns to limit the number of embryos that we
1:08:34 make or only transfer embryos that are created.
1:08:36 And that's important to know to bring that up if that's your line
1:08:40 in the sand is that we can often do things differently based on your beliefs.
1:08:45 It might be less efficient.
1:08:47 It might cost more money.
1:08:48 It might have a lower rate of success.
1:08:50 But I've had patients walk that road
1:08:52 and that's the way it felt comfortable to them.
1:08:54 In this country, there's a camp and that's not too political.
1:08:57 Um they're really pushing something called restorative
1:08:59 reproductive medicine and they're opposing a lot
1:09:01 of the American Society for Reproductive Medicine's um
1:09:05 attempt to get fertility treatment and fertility preservation covered.
1:09:09 And their rationale, even though a lot of RRM, I'm a huge fan of.
1:09:13 It's about teaching women cycle tracking and getting
1:09:15 to the root cause and really supporting understanding your fertility.
1:09:19 Like bullet point 10 on their list is that IVF is unethical.
1:09:23 But these people are ostensibly pro-child.
1:09:25 So, that I sorry.
1:09:27 I'm I'm not a pro- my political stance, I people often speculate.
1:09:29 Like, I'll be really honest, I don't like politics and I'm very disappointed
1:09:34 in the current state of politics um on both
1:09:37 sides and I try and go issue by issue
1:09:39 and I realize that itself is a controversial statement.
1:09:41 You're supposed to take a hard stance for or against,
1:09:43 but I think that as a biologist, um I look at certain things and I go,
1:09:48 "All right." Like, and I look at other things and go,
1:09:50 "Oh my goodness, like like what Stone Age are we living in?" And so,
1:09:53 I think that um to argue uh whatever it is that one
1:09:57 believes about it seems to me that IVF, at least to me,
1:10:02 maybe I just I'm too uh through my own lens,
1:10:06 but the whole notion of freezing eggs
1:10:08 and creating embryos seems very pro-child to me.
1:10:11 So, it doesn't square with with number 10 on this list.
1:10:14 with you.
1:10:16 I agree with you and I think a lot of the people
1:10:17 who are a fan of ARM might actually agree with you and I,
1:10:21 but there's definitely people who are very adamantly opposed to IVF
1:10:24 who put number 10 in there because they have a different agenda.
1:10:27 Okay.
1:10:28 I'm a fertility doctor, right?
1:10:29 I want as many people to have a family as they desire.
1:10:33 I want you to fulfill your life's dreams.
1:10:36 If having a child is a part of it,
1:10:37 I want to do everything I can to help you have that.
1:10:40 I am not here to sell IVF or force IVF.
1:10:44 I, at the end of the day, it impacts me zero what you individually choose to do.
1:10:48 But I believe that across the board, people deserve the tools in the toolbox.
1:10:53 They deserve to be presented with all the choices.
1:10:55 We could try Clomid, we could try IUI, we could try surgery, we could try IVF.
1:11:00 Oh, you're getting older, we could freeze your eggs.
1:11:02 There's just more tools, there's more opportunities.
1:11:04 And then based on your circumstance, your financial,
1:11:07 your beliefs, you should be allowed to choose.
1:11:10 I feel very adamantly that one's own beliefs that cause you to want to put it
1:11:15 at number 10 on the list should not be the beliefs that we enforce on everybody,
1:11:20 especially when we know that IVF can be so
1:11:23 powerful to help so many people have a family.
1:11:27 It should be something that is offered
1:11:29 to you if indicated and you get the choice.
1:11:31 And so, back to the origin, it would be incredible to live in a world,
1:11:37 a country where egg freezing was offered to women as we
1:11:41 do see people are waiting longer to start their families.
1:11:44 It would allow more people to feel less pressure,
1:11:47 less pressure with a partnership and on their relationship,
1:11:49 not to feel like, "Oh,
1:11:50 this better work out because my clock is ticking." And be able to really
1:11:54 feel like they could chase one dream and not at the expense of another.
1:11:59 I think we're further in this country than we want to admit from that.
1:12:01 We can't even get fertility treatments covered for patients with cancer
1:12:05 when we know that chemotherapy is going to deplete their ovarian reserve.
1:12:10 We have some states that we can't even get egg freezing covered for them.
1:12:14 So, this is state by state?
1:12:15 This is state by state right now.
1:12:17 We would We would love federal protection for everybody.
1:12:20 We would love to be able to see I don't know, to me that's my litmus.
1:12:24 What your state or your country would do for patients who have cancer,
1:12:28 you know, are are in this position.
1:12:30 And if we're not even willing to move to help them,
1:12:33 the idea that we could cover it for everybody,
1:12:36 we're still ages away from that, I think.
1:12:39 Yeah, because uh it's not I don't know if
1:12:41 what we're talking about is forcing anyone to do anything.
1:12:45 Um nor is it necessarily the destruction of an embryo.
1:12:49 I mean, it's there is a world where
1:12:50 the embryos are created and kept frozen, right?
1:12:52 There is a there is no uh Yeah.
1:12:55 We call that embryo banking.
1:12:56 I mean, to specify maybe for somebody who doesn't understand, right?
1:12:58 Egg freezing, getting those eggs outside the vault to grow,
1:13:01 taking them out of your body and we freeze them right there at the egg state.
1:13:05 Making an embryo is going to be thawing that egg, fertilizing it with sperm,
1:13:11 letting it grow out to the implantation stage, which is day five or six.
1:13:14 Not every egg will survive, fertilize, grow.
1:13:17 There's a ton of attrition in culture.
1:13:19 So, 90% of eggs survive the freeze-thaw.
1:13:22 75% will fertilize.
1:13:25 50% will make it to the implantation stage and then not
1:13:28 everyone will be genetically normal based on your age and other factors.
1:13:31 And then even a genetically normal embryo only has a 65% chance of live birth.
1:13:36 Like, the science has come far, but we're not there all the way.
1:13:40 With that being said,
1:13:41 they do morally really feel like an embryo could be a potential life
1:13:45 and they do struggle with what to do if they have leftover embryos.
1:13:50 And I have some patients who've told me,
1:13:51 "Every embryo we make, we're going to transfer." Okay,
1:13:54 well, we want to be really mindful what we do in that circumstance.
1:13:57 And even though it's unlikely,
1:13:59 I have a patient right now with four children and one embryo in the freezer
1:14:02 cuz we froze five knowing that everyone
1:14:05 shouldn't implant based on that 65% number, but we've gone four for four.
1:14:09 Okay?
1:14:10 So, like we have to know that if that's what we're doing,
1:14:12 we're prepared for how the data may fall
1:14:15 because data just helps us guide decisions, right?
1:14:17 Especially when it comes to live birth, it's a zero or 100.
1:14:19 It happens or doesn't.
1:14:21 Now, if I freeze them as eggs for some patients who
1:14:24 have really strong beliefs and they are afraid of that number five,
1:14:27 we might take more time or time more money, but we might say,
1:14:30 "Let's thaw them and only fertilize two." Leave everything else frozen.
1:14:34 And then whatever makes it embryo, we can transfer.
1:14:36 And yes, that's not a cost-effective way to go
1:14:39 through the process cuz we might be having to pay
1:14:41 for thawing and the fertilization and the transfer more times
1:14:45 because there may be nothing to transfer based on that attrition.
1:14:48 It can let some patients say, "Okay, I feel better with that process." So,
1:14:53 just freezing eggs, to your point, isn't not making embryos, right?
1:14:57 And there's different things we can choose along
1:14:59 the way to make an individual person feel comfortable,
1:15:02 but we shouldn't be dictating how the field has to function.
1:15:06 I think it would be incredible if we could encourage egg freezing earlier.
1:15:09 I think it would open the door of opportunity.
1:15:12 And not everybody who freezes eggs will need them,
1:15:14 but the peace of mind knowing that there's
1:15:16 a chance is really impactful on the human mind.
1:15:21 I'd like to take a quick break and acknowledge our sponsor, Eight Sleep.
1:15:24 Eight Sleep makes smart mattress covers with cooling,
1:15:27 heating, and sleep tracking capacity.
1:15:29 One of the best ways to ensure you get a great night's sleep
1:15:31 is to make sure that the temperature of your sleeping environment is correct.
1:15:35 And that's because in order to fall asleep and stay deeply asleep,
1:15:38 your body temperature actually has to drop by about 1 to 3°.
1:15:42 And in order to wake up feeling refreshed and energized,
1:15:44 your body temperature actually has to increase by about 1 to 3°.
1:15:48 Eight Sleep automatically regulates the temperature of your bed
1:15:51 throughout the night according to your unique needs.
1:15:53 I've been sleeping on an Eight Sleep mattress cover for nearly 5 years
1:15:56 now and it has completely transformed and improved the quality of my sleep.
1:16:01 The latest Eight Sleep model is the Pod 5.
1:16:03 This is what I'm now sleeping on and I absolutely love it.
1:16:06 It has so many incredible features.
1:16:08 For instance, the Pod 5 has a feature called Autopilot,
1:16:11 which is an AI engine that learns your sleep patterns and then
1:16:14 adjusts the temperature of your sleeping
1:16:15 environment across different sleep stages.
1:16:17 It'll even elevate your head if you're snoring
1:16:20 and it makes other shifts to optimize your sleep.
1:16:22 If you'd like to try Eight Sleep,
1:16:23 go to eightsleep.com/huberman to get up to $350 off the new Pod 5.
1:16:29 Eight Sleep ships to many countries worldwide including Mexico and the UAE.
1:16:33 Again, that's eightsleep.com/huberman to save up to $350.
1:16:38 So, in insurance I would think would want to do
1:16:43 this because um covering all the other stuff is expensive, too.
1:16:48 Most insurance doesn't cover IVF.
1:16:51 You're not wrong, right?
1:16:52 In principle, if I freeze a 25-year-old's eggs,
1:16:55 I will have three times as many eggs to work with, you know,
1:16:59 than I would if she's going through IVF when she's 37.
1:17:03 So, if I'm going to pay for her to do IVF at 37,
1:17:05 it'll take so many more cycles, I'll spend so much more money.
1:17:08 That one cycle of egg freezing is
1:17:10 much more cost-effective if I'm covering them both,
1:17:14 but we don't even cover the latter.
1:17:16 So, many times patients, this is such a hard stretch for everybody.
1:17:21 And look, the technology is incredible.
1:17:25 As somebody who has an IVF lab,
1:17:27 as somebody who keeps embryos on site, it's I mean, it's outrageously expensive.
1:17:32 I mean, our generator alone is like a million dollars, right?
1:17:35 Because if the power goes out, like what do we have to keep going?
1:17:39 We always say, "If there's zombies coming,
1:17:40 like come to the clinic." The technology to keep up with all the advancements,
1:17:46 to have trained embryologists, I mean,
1:17:48 their micro-manipulation skills, it's impressive.
1:17:51 So, it costs money to run a lab like that that will provide results.
1:17:54 So, the process and the technology is really, really expensive.
1:17:57 That being said, like I shouldn't be the one sitting here
1:18:00 making assumptions again on what you're going to do with your money.
1:18:03 And if somebody's in a position where they know
1:18:06 their egg count's low and they should freeze their eggs
1:18:09 because they're not partnered or they're not ready
1:18:11 to get pregnant and they don't have the financial resources,
1:18:16 we can sometimes find more money, right?
1:18:18 We make decisions every day when it comes to money.
1:18:19 We can't find more time.
1:18:21 We can't find more eggs or more ovary.
1:18:23 So again, this idea that, "Well, what are they going to do about it if
1:18:26 they find out they have a low AMH?" Or, "Oh,
1:18:27 they can't afford to freeze their eggs anyway." Or, "Oh,
1:18:30 it's too expensive." We all make individual
1:18:33 choices on how we leverage our different resources,
1:18:36 which I consider to be your time,
1:18:37 your money, your physical energy, and your emotional energy.
1:18:41 And every day, you're leveraging them.
1:18:43 But when it comes to reproductive health, having a family,
1:18:46 like I I feel strongly, you feel strongly,
1:18:48 which I love, that we should be giving more access
1:18:51 and more options to people so that they can pursue this.
1:18:54 So, the arguments are across the board, too.
1:18:56 Like, why not check an AMH in somebody who's younger?
1:18:58 Well, they can't afford egg freezing anyway,
1:19:00 so what are they going to do about it?
1:19:02 Again, like we shouldn't be making the assumptions of what somebody
1:19:05 will or will not do with their resources or with their data.
1:19:09 We should be ones helping them get the data and interpret the data,
1:19:12 understand what resources or options exist,
1:19:15 and then the individual has what they need to make the decision.
1:19:20 In the Bay Area where there a of tech companies,
1:19:23 um there's a uh my understanding is there's a an opportunity
1:19:28 at many of these companies for female employees to freeze their eggs.
1:19:31 That landed much more controversial than I thought it would.
1:19:35 Isn't it crazy?
1:19:35 Um because the the assumption, the sort of uh to some people uh
1:19:41 the tacit message there is "Don't have kids now.
1:19:44 Work work work work like crazy and then have them later, right?" But
1:19:49 having known some people that work there and froze
1:19:51 their eggs in their um late 20s or early 30s, I think they would say,
1:19:56 the ones I know would say, "I'm really grateful that I did that um
1:19:59 and that the company I worked for paid for it.
1:20:01 And they got to keep their eggs even
1:20:02 though they don't work for the company anymore.
1:20:04 So there's that.
1:20:05 But it was kind of interesting.
1:20:06 So anyway, we're getting kind of we are.
1:20:08 But what we are finding is that Yeah, what data supports is that when companies
1:20:14 do leverage a fertility package in their benefits,
1:20:18 they retain employees longer, employees are happier,
1:20:22 and more people utilize the service than would without it.
1:20:25 Meaning people freeze their eggs when
1:20:26 it's offered to them through their company,
1:20:28 and that gives them that peace of mind.
1:20:31 Understanding is not everything,
1:20:32 but they feel more comfortable exploring bigger opportunities,
1:20:36 and they are grateful to the company.
1:20:38 They stay with the company longer because
1:20:40 that is an investment in your employees.
1:20:42 I think it's incredible.
1:20:43 In Austin, right, a lot of these tech companies have second homes.
1:20:45 So we see a lot of these patients also.
1:20:47 And I do think that has changed game
1:20:50 for so many people to be able to have access.
1:20:53 Because for many it's not ethical or moral, it's financial.
1:20:58 The often the time when you would freeze your eggs,
1:21:00 when it would give you the highest rate of return,
1:21:02 you don't have the resources to do so.
1:21:05 So having a company that's able to come
1:21:06 in and do that is really I think impactful.
1:21:10 I wish more companies would do that.
1:21:11 Maybe we can change their minds.
1:21:12 I tend to get pretty loud and pretty consistently
1:21:14 loud about the things that uh I believe in.
1:21:17 Once I understand the landscape, so I I plan to be vocal about it.
1:21:21 Um for what it's worth.
1:21:22 Uh you mentioned that birth control can
1:21:24 reduce AMH levels um on a month-to-month basis.
1:21:28 Is there and we should define birth control cuz it's such a broad category.
1:21:33 Um but is there any evidence that taking hormonal birth control
1:21:38 can lower chances of pregnancy when somebody comes off birth control?
1:21:44 In my friendships and knowledge space, my um and this isn't I have a friend.
1:21:50 I just I know a number of people who have kids now who um were on birth control,
1:21:54 came off birth control, and got pregnant right away.
1:21:56 Right.
1:21:56 So I think a lot of people assume that's how it works.
1:21:59 But are there any uh good examples of how certain forms of birth
1:22:02 control can actually suppress fertility in women
1:22:06 long after women come off birth control?
1:22:08 Excellent question.
1:22:08 Okay, let's break the data down from big to little.
1:22:11 Number one, big studies looking at all different types of contraception,
1:22:14 no higher rate of infertility,
1:22:16 again defined as failure to get pregnant at 12 months.
1:22:20 So you come off your contraception at 12 months later when we look,
1:22:23 there's no higher rate of infertility than
1:22:24 we would have on the population based level.
1:22:26 So that data leads us to comfortably
1:22:28 say birth control is not causing infertility.
1:22:31 Now if we go and we look more nuanced at different types of contraception.
1:22:35 If you look at the birth control pill, what most people are talking about,
1:22:38 the birth control pill is a combination of synthetic estrogen,
1:22:42 ethanol estradiol, and a type of progesterone or a progestin.
1:22:45 These work by telling the brain, essentially tricking it,
1:22:49 so the brain doesn't send out FSH or LH.
1:22:51 And as we described earlier, those are important in getting you to ovulate.
1:22:54 So you don't ovulate when you have taking the birth control pill,
1:22:57 and that's why it's a very effective contraceptive choice.
1:23:00 However, the half-life of the birth control pill is only 28 hours.
1:23:03 So it's actually quite short.
1:23:05 So you can miss even just one pill and you could ovulate.
1:23:08 So when you stop the birth control pill,
1:23:10 your period should come back that next month.
1:23:13 So immediately you should have resumption of ovulation.
1:23:17 A couple of problems with this one is
1:23:20 that the birth control pill has some valid medical uses,
1:23:25 has some non-valid ones, but very often,
1:23:27 especially in the generation of women that we see right now,
1:23:30 they were given the pill potentially for a valid
1:23:33 medical reason without any investigation of what it was.
1:23:36 So maybe a woman had irregular cycles or some acne, and her doctor said,
1:23:39 "Well, here, take the birth control pill, it will help." And it did help.
1:23:43 But just based on that history, I would sit here and say,
1:23:45 "I bet she has PCOS." And the woman though never was told,
1:23:50 "I think you have PCOS.
1:23:52 Here's what it is.
1:23:53 You probably will not ovulate when you stop the birth control,
1:23:55 and your acne will come back, and you should talk to a fertility doctor,
1:23:58 and here's lifestyle things we can do
1:24:00 to decrease insulin resistance." Never had that discussion.
1:24:03 [clears throat] So in her mind, had some symptoms, started the pill.
1:24:06 Those symptoms resolved.
1:24:07 Now we stop the pill and we're not getting pregnant,
1:24:09 and we have irregular cycles, and we start to blame the pill as the reason why,
1:24:14 instead of understanding that the pill was maybe
1:24:16 masking it or treating certain aspects of it.
1:24:18 So we do see failure to get to a diagnosis
1:24:22 in women who were prescribed the birth control pill young,
1:24:25 and then with the idea I'm going to stop the pill and get pregnant right away.
1:24:28 What I like to say is you're not ovulating on the pill.
1:24:31 If ovulation and knowing when you ovulate is one of your most
1:24:34 sensitive health markers and really essential
1:24:36 information in trying to get pregnant.
1:24:38 If you are trying to get pregnant, the egg only lives for 24 hours.
1:24:42 The fertile window is the 5 days before and the day of ovulation.
1:24:46 Meaning sperm can live in the reproductive tract for up to 5 days.
1:24:49 Most will stay around for 2 days.
1:24:52 That's why the 2 days before and the day of ovulation have
1:24:54 a 20 to 30% chance of getting pregnant compared to a 0 day,
1:24:58 the day after ovulation, 0%.
1:25:00 So very defined fertile window.
1:25:02 So if you know when you're ovulating and you target intercourse,
1:25:05 you're going to have higher odds and get pregnant faster.
1:25:07 Data supports that very much so.
1:25:10 But you don't know how to track your ovulation cuz you've been on the pill.
1:25:13 So you don't know how to do that.
1:25:15 So I recommend that you stop the pill three to six months before
1:25:18 you're really wanting to start your family so you can track your cycle,
1:25:21 learn to detect ovulation.
1:25:23 And if you do have an abnormality,
1:25:25 you're not now six months of trying or one year of trying before it's evaluated,
1:25:29 you can say, "Oh, I can't detect ovulation or my cycles are irregular.
1:25:33 Let me go get that investigated now so we're not kind of behind
1:25:37 in our own timeline." The progesterone IUD is
1:25:41 another one that we talk about a lot.
1:25:42 The progesterone IUD is local progesterone that is placed inside the uterus.
1:25:46 There's different types that can release progesterone in different amounts.
1:25:50 It typically suppresses ovulation in the first 2 years,
1:25:53 but then progesterone levels drop and it tends not to suppress ovulation,
1:25:57 but that chronic progesterone exposure thins the endometrial lining
1:26:01 to the degree that many women do not have periods anymore.
1:26:05 That can be great if you don't like having a period.
1:26:08 That can decrease the chance of anemia or menstrual cramping.
1:26:11 So it can be very lifestyle positive during those years.
1:26:15 But when you stop the IUD, we do see a change in endometrial receptivity
1:26:19 at least for 6 months after it's been removed,
1:26:22 and it can take time to build that lining back up.
1:26:25 So I always recommend that a progesterone IUD is removed
1:26:27 at least 6 months before you want to get pregnant.
1:26:30 Give the endometrium time to rebuild and regrow,
1:26:33 and then you'll have better odds at conceiving.
1:26:36 We do see a little bit of lower pregnancy rates in those first
1:26:40 6 months of conceiving in women coming off of the IUD.
1:26:43 More of them are getting pregnant in the back 6 months.
1:26:45 So kind of shift your own timeline.
1:26:48 And the birth control thing that's always important to mention
1:26:50 in this conversation is one that's not as common,
1:26:52 but it's the Depo-Provera shot.
1:26:54 So this is a high-dose intramuscular progesterone
1:26:56 shot that can prevent ovulation for 3 months.
1:26:59 On population based levels, to use it as an effective contraceptive,
1:27:03 must get every 3 months.
1:27:04 But one single dose can prevent ovulation for 18 months.
1:27:09 So this is that one exception where if you
1:27:11 want to get pregnant potentially in the next 2 years,
1:27:15 please don't get Depo-Provera.
1:27:17 Great.
1:27:17 Incredibly thorough and clear.
1:27:20 Is there any evidence one way or the other that intentional
1:27:23 termination of a pregnancy can disrupt chances of getting pregnant again later?
1:27:28 No study supports that having a termination
1:27:30 is going to negatively impact your fertility later.
1:27:33 One caveat I just want to mention is that any intrauterine procedure
1:27:37 has the potential to damage the endometrium and result in scar tissue.
1:27:41 So that could be having an IUD,
1:27:43 could be having a fibroid removed, could be a prior C-section,
1:27:46 it could be a prior D&C because you had a pregnancy loss,
1:27:49 it could be from a termination.
1:27:51 Where we see the greatest risk in all of these circumstances
1:27:54 is from heavy bleeding or from an infection associated with it.
1:27:59 So in general, most terminations are done early, very routine.
1:28:03 Where we are fearful is when they are accessed in non-safe environments,
1:28:08 we're seeing more infection or heavy bleeding,
1:28:10 or even when women are having to travel statewide to access care,
1:28:14 and they're getting the procedure done later with a higher risk of complication.
1:28:18 In Texas, where I practice, there's obviously an abortion ban,
1:28:21 and so women who need an elective termination for a medical reason,
1:28:25 I had one patient who's been very open about her story.
1:28:29 Her baby had anencephaly.
1:28:30 So she went through IVF and had a baby that had no brain develop.
1:28:35 And they made the decision that they wanted
1:28:36 to terminate that pregnancy since that's not compatible with life.
1:28:39 They don't want to have to carry the entire pregnancy.
1:28:41 They had to travel out of state to access care.
1:28:44 Their first appointment was canceled.
1:28:46 So they had to make another one in a different state.
1:28:49 Took them much longer than they wanted, had the procedure much later.
1:28:53 And then she had residual scar tissue inside
1:28:55 her uterus that was because it was done
1:28:57 at a later term that we then had to fix before she could get pregnant again.
1:29:01 So I think it's just important to say that across
1:29:03 the board any intrauterine procedure poses a little bit of a risk.
1:29:07 No matter what it is, if your periods are different afterward,
1:29:10 the hallmark sign is going to be a lighter cycle.
1:29:12 So no matter what thing on that list you had done,
1:29:14 if your cycle is now lighter afterward,
1:29:17 I am worried there could be scarring inside the uterus,
1:29:20 and we'd rather evaluate that in the clinic.
1:29:22 We can do a saline sonogram to just check and make
1:29:24 sure there's no scar tissue because that will impact your fertility.
1:29:28 Thank you.
1:29:29 Um some practical questions about metabolic health,
1:29:35 mitochondrial health, and egg quality.
1:29:36 Let's do it.
1:29:38 Um in your book you go into this in some degree of detail,
1:29:40 but um when you think about the things
1:29:43 that can really um help support egg quality, aside from age, Yeah.
1:29:49 um in fact, I should say at any age,
1:29:51 uh what are the you know, sort of top contour of those?
1:29:56 Um you mentioned inflammation is the enemy,
1:29:58 but inflammation happens all the time, and we can't avoid it.
1:30:02 Um but we can certainly avoid exacerbating it.
1:30:04 So, what are the things that people can do, not do, and take?
1:30:08 We can do the inverse of that.
1:30:10 Do, not do, and take.
1:30:11 Okay.
1:30:12 So, yes, inflammation is prevalent in our world,
1:30:16 and the goal is not to avoid all of it.
1:30:18 In fact, acute inflammation is required for conception, right?
1:30:23 We need acute inflammation with ovulation.
1:30:25 If we just think real physiology, a follicle is rupturing,
1:30:31 allowing the egg to be released and then reforming.
1:30:33 Like, we need our acute inflammatory response to allow that to happen.
1:30:36 To the degree that if women take NSAIDs around the time of ovulation,
1:30:39 Advil, ibuprofen, Aleve, they'll prevent the follicle from rupturing.
1:30:44 Really?
1:30:44 Yes, so they'll go through the hormonal changes of ovulation,
1:30:47 but the egg will not be released.
1:30:49 So, that's why we recommend, and you know, fun fact or important to know,
1:30:53 if you're trying to get pregnant,
1:30:54 you can take those medications only when you're on your period.
1:30:57 So, period cramping, fine, but we don't want you taking them for the rest
1:31:00 of the cycle because you can prevent ovulation from occurring.
1:31:03 How many people in your experience you think know that?
1:31:06 I don't think very many, honestly, right?
1:31:09 Which is which is one it's sort of like banner across the sky.
1:31:12 Like, these you're not going to lose eggs by doing a a free cycle,
1:31:15 collecting free cycle, the um I mean,
1:31:18 Basic facts about our biology that we are never taught.
1:31:21 So, if somebody's trying to get pregnant, NSAIDs can be problematic.
1:31:24 They can be problematic.
1:31:25 They can prevent the egg from being released with ovulation.
1:31:28 So, I think that this is important because I will sometimes have patients say,
1:31:32 "Well, if inflammation's bad, can I just take medicine for it?" Right?
1:31:36 Like, that in our brain might make sense.
1:31:39 And I always want to say,
1:31:39 "Your immune system is essential for ovulation and also for implantation." So,
1:31:43 I can't I don't want to turn off your immune system.
1:31:46 What I want to do though is not have
1:31:48 it be so burdened with what we call chronic inflammation,
1:31:50 that constant activation, where it can't even do the job that we need it to do.
1:31:55 So, I like to think about this as that inflammatory burden,
1:31:58 and it's so we're all exposed to some,
1:32:00 but how do we to your degree make it better?
1:32:03 How do we add to it and make it worse?
1:32:06 And really framing ourselves so that we can cultivate and I
1:32:08 like to think about it as resilience within your body.
1:32:12 I mean, you're going to be exposed to inflammation.
1:32:14 Life is going to throw things at you,
1:32:16 but you want to cultivate these best practices of your life
1:32:19 so that you are reducing inflammation to the degree that you had,
1:32:23 and this goes hand in hand with insulin resistance, which we'll get into.
1:32:26 And I usually divide it into like what I call my five non-negotiables of sleep,
1:32:30 stress, muscle, food, and toxins.
1:32:33 And thinking about how we leverage these to our benefit by giving
1:32:37 people the knowledge that they can if they understand their bodies,
1:32:43 they can then be empowered to make choices that are in line with their goals.
1:32:48 And so, I really I'll just want to say really importantly,
1:32:51 I hate the narrative that there's nothing you can do for your fertility
1:32:53 or that it's all luck because the truth is even if we can't control everything,
1:32:58 we have a huge control over our metabolic and cellular health,
1:33:02 which as we just said plays a huge role
1:33:04 in our ability to get pregnant for both men and women.
1:33:07 So, taking control of what we can,
1:33:10 I think is really important information and one person can
1:33:13 take with that and make the choices they want to make.
1:33:16 But the worst thing that I hear every
1:33:17 single day is people sitting across from me saying,
1:33:19 "Gosh, I wish I'd known that information.
1:33:22 I would have made a different decision." Why do
1:33:24 we make people go through a failed IVF cycle, they have no embryos form,
1:33:28 and only then do they make lifestyle changes when we know
1:33:30 the lifespan of a sperm is 90 days and sperm are so sensitive.
1:33:34 And then we know that even though eggs are in your body your whole life,
1:33:37 the 60 days before you get pregnant is when
1:33:40 the egg is most susceptible to the world around you.
1:33:42 So, this is this time period that I like to call trimester zero,
1:33:46 the time before you're getting pregnant where the choices you
1:33:49 make can influence your egg and sperm quality the most.
1:33:52 And what you said earlier, if we're making them even earlier in life,
1:33:55 can we influence ovarian function longer?
1:33:57 I think there is good thought to that.
1:33:59 But how do we leverage these choices and diving into them?
1:34:03 Number one for me is sleep, and I think that this is an important one
1:34:06 because it can leverage that inflammatory burden in both ways,
1:34:08 and I know you're a big fan of sleep,
1:34:10 so this isn't going to take much to convince you.
1:34:12 When you sleep, this is when your body's
1:34:14 going to get rid of some excess chronic inflammation,
1:34:16 lowers our inflammatory markers.
1:34:19 We know that when we get less sleep,
1:34:22 it's going to cause us to have more cellular stress, more oxidative stress.
1:34:26 Your gonadotropins, so FSH and LH,
1:34:28 are released from the brain in the early morning hours.
1:34:31 So, when you don't sleep long enough,
1:34:33 you're not going to have the same hormonal response.
1:34:35 And we know really directly, men who get less sleep,
1:34:38 they have lower testosterone levels and lower sperm counts.
1:34:41 Women who get less sleep get fewer eggs at IVF cycle.
1:34:45 And we see that if you say you have poor sleep,
1:34:48 you have double the rate of infertility.
1:34:49 If you just objectively say, "Yeah,
1:34:50 I have poor sleep," you have double the rate.
1:34:53 And that people who are not sleeping well,
1:34:56 either partner, it will take them longer to get pregnant.
1:34:58 They have lower fecundability, that month-to-month pregnancy rate.
1:35:01 So, it's not just me sitting over here saying, "Oh, yeah,
1:35:03 you need to sleep better." Like, your physiology is meant to sleep.
1:35:07 It is a sign to your brain,
1:35:09 if we go back and we view that hypothalamic response as central command station,
1:35:14 looking for clues that your life is stable enough,
1:35:18 you're healthy enough to carry a pregnancy for a woman,
1:35:20 which is a huge metabolic spend.
1:35:23 It's looking to make sure you're taking care of yourself primarily,
1:35:26 and sleep is one of the most powerful markers that we can move.
1:35:30 7 to 9 hours.
1:35:31 Most women need closer to 7 and 1/2, especially in the luteal phase.
1:35:35 Making progesterone is a big body spend.
1:35:38 We really have to cultivate better sleep.
1:35:41 You know, all the things you talk about.
1:35:42 Dark room, sound machine, a sleep mask, a cooler temperature.
1:35:46 Takes two to tango, so if you sleep in the bed with somebody,
1:35:49 they need to be on board.
1:35:50 You need to go to bed at the same time,
1:35:51 you need to have similar sleep practices.
1:35:53 And we know that day-to-day consistency is also impactful in fertility.
1:35:58 So, not just the length of time,
1:35:59 but really having that good circadian rhythm is so important for your hormones.
1:36:04 Melatonin is obviously released before you go to bed.
1:36:07 Slow doses of melatonin supplementation can impact fertility,
1:36:10 so doses of 1 to 3 mg 30 minutes before you
1:36:13 go to bed can improve your odds of getting pregnant as well,
1:36:17 can improve egg quality.
1:36:19 And we know that naturally you make more melatonin when you ovulate
1:36:22 to kind of counter some of the oxidative stress to the ovary.
1:36:25 Really have to be careful though,
1:36:26 a lot of over-the-counter products have like 10 times the amount of melatonin,
1:36:29 so I always want to tread lightly with that one in recommending it to patients.
1:36:33 Often a pediatric dose is like 1 mg,
1:36:35 and that's the perfect amount just to augment.
1:36:38 Again, we're not trying to replace your body's melatonin.
1:36:40 We want to augment it and kind of help
1:36:42 your body I always like to think about like a toddler,
1:36:44 really get good consistency with your wind-down
1:36:47 routine so that you can get enough sleep.
1:36:49 I don't want to disrupt your flow,
1:36:50 but if a woman is already sleeping well, should she take melatonin?
1:36:54 I would say for the average person, probably don't need to.
1:36:57 I would say the exception to the rule would
1:36:59 be that if we know we have increased chronic inflammation,
1:37:01 maybe we have endometriosis or an inflammatory autoimmune disease,
1:37:05 or we're going through IVF with unexplained infertility,
1:37:08 or ever been kind of told you have quote bad egg quality,
1:37:12 then the anti-inflammatory properties of it might be advantageous.
1:37:16 Since NSAIDs can disrupt the inflammation requirement for ovulation,
1:37:22 um I'm curious about other things
1:37:24 that are known to potently reduce inflammation.
1:37:27 Um I I think enough terrible things have been said about
1:37:30 cold plunges um that we don't need to add any more,
1:37:32 but we're seeking reality here.
1:37:35 Uh and I don't have and despite common belief,
1:37:37 I don't have anything inherently attached to cold plunges.
1:37:40 I do them sometimes,
1:37:41 but we know that one shouldn't do them after resistance training um or any
1:37:45 kind of exercise where you want the inflammation
1:37:48 to get the adaptation to the exercise.
1:37:49 We know that.
1:37:50 And it's a pretty potent inhibitor of inflammation.
1:37:53 So, is there any reason to think that in the time where
1:37:56 somebody's trying to conceive that perhaps they should avoid the cold plunge?
1:37:59 I usually recommend against them for reasons stated here.
1:38:02 I think there's very few things we have that are going to really
1:38:05 turn off that acute inflammatory response to the degree that NSAIDs do,
1:38:09 but we should proceed with caution in doing those things.
1:38:12 Most everything else is trying to just
1:38:15 get rid of the excess inflammation we have,
1:38:17 but if something's dampening down into that acute inflammatory response,
1:38:20 then I think we have to be a lot more judicious in saying, "Yeah,
1:38:23 go for this." So, I'm not a fan of cold plunges when trying to get pregnant.
1:38:27 A lot of people will be very happy to hear that cuz I don't Unlike the sauna,
1:38:31 nobody likes the cold plunge.
1:38:32 I hate a cold plunge.
1:38:33 I tried it I tried it one time, and that was one time too many.
1:38:36 I would say if you if you like it, great.
1:38:38 If you think you benefit, great, but otherwise, don't worry about it.
1:38:41 Um one thing that's commonly used is um curcumin.
1:38:44 Yeah.
1:38:45 And it's a pretty potent anti-inflammatory.
1:38:47 Do you recommend people stay away from Let's not cooking with curcumin,
1:38:51 but the high-dose curcumin that comes in a lot of of supplements.
1:38:55 usually recommend it in a supplement form.
1:38:56 Like, I I I never recommend it.
1:38:58 I think if you have a doctor who's giving it for very specific purpose,
1:39:01 you might be a unique person who
1:39:03 has excess inflammation they're trying to target,
1:39:06 but that's not something that I recommend.
1:39:07 But cooking with it is fine.
1:39:09 NAD and NR are I get asked about them thousands of times
1:39:14 per week and I'm more or less a fan of NR
1:39:18 or NMN if one is trying to I don't know I don't
1:39:21 think it will extend lifespan but it does seem to at least
1:39:24 in my experience increase energy these kinds of things um but it's
1:39:29 NR in particular there's data that it can be very anti-inflammatory so if
1:39:33 a woman is trying to conceive should she stay away from NMN
1:39:36 NAD and NR cuz I often see it listed in in fertility protocols.
1:39:41 Animal data looks like NAD and NMN can
1:39:44 be advantageous especially for unexplained infertility which to be
1:39:49 clear is different than I just want to get
1:39:51 pregnant right in unexplained infertility you're not conceiving we
1:39:54 do the basic test anatomy ovulation ovarian reserve
1:39:58 semen analysis they're all fine so I view
1:40:00 that as chronic inflammation unless proven otherwise and so
1:40:04 that's a unique situation that patients may have potential benefit.
1:40:10 But unlike certain things across the population
1:40:12 that we can feel really comfortable recommending I
1:40:15 don't recommend that to everybody so I think
1:40:16 that there might be utility in certain subgroups
1:40:20 who are kind of really falling off
1:40:22 the curve and we think there's excess inflammation
1:40:24 that it could make sense for so I don't ever say no and I sometimes use it.
1:40:28 But on like the flip hand we could say
1:40:29 like CoQ10 which has robust human data that is advantageous
1:40:34 without a negative benefit that's an easier place to leverage
1:40:37 your supplement dollars if you're going to spend cuz most
1:40:40 of us don't want to spend endless amounts on all
1:40:42 the things that we can craft for our supplement
1:40:44 list but the human data is yet yet to be
1:40:46 out although animal data looks promising for the right patients.
1:40:50 I'm glad you mentioned coenzyme Q10 CoQ10 and L-carnitine are the two
1:40:55 at least I'm aware of there's some decent data on supporting sperm
1:40:59 and egg quality so do you encourage patients to start taking that what
1:41:04 60 days before trying to conceive and then continuing that through pregnancy?
1:41:08 We usually stop CoQ10 in pregnancy just because of lack
1:41:11 of data we're very cautious in pregnancy of not
1:41:15 exposing you to anything additional you may not need
1:41:18 so we just want to be really mindful of that.
1:41:21 But I think it's in my like everybody should take before you get
1:41:24 pregnant yep at your trimester zero your hey we want to get pregnant
1:41:27 soon we should take a prenatal vitamin that has folic acid we should
1:41:30 take CoQ10 we should take omega-3 fatty acids we should take vitamin D.
1:41:35 These are all going to optimize make giving
1:41:37 you the nutrients you need for a pregnancy
1:41:39 helping support my good mitochondrial health which is
1:41:41 important for egg quality without risk of harm
1:41:45 to any of these specific supplements so these are
1:41:47 the universal we're trying and then for sperm
1:41:50 health L-carnitine we like a lot and then
1:41:52 zinc and selenium can have benefits as well.
1:41:55 I know you cover specifics in the book so
1:41:57 we'll we'll leave it to people to find it there.
1:42:00 everybody who's like very curious based on disease state and and more info.
1:42:05 I'd like to take a quick break and acknowledge our sponsor Function.
1:42:08 Function provides over 160 advanced lab tests to give
1:42:12 you a clear snapshot of your bodily health.
1:42:14 This snapshot gives insights into your heart health
1:42:17 hormone health autoimmune function nutrient levels and much more.
1:42:21 They've also recently added access to advanced MRI and CT scans.
1:42:25 Function not only provides testing of over
1:42:27 160 biomarkers key to your physical and mental
1:42:30 health it also analyzes these results and provides
1:42:33 recommendations for improving your health from top doctors.
1:42:36 For example in a recent test with Function
1:42:39 I learned that some of my blood lipids were slightly out of range as a result
1:42:43 I decided to start supplementing with nattokinase which
1:42:45 can naturally help reduce LDL cholesterol and it
1:42:48 did in a follow-up test I could confirm
1:42:50 that this strategy worked my blood lipids are
1:42:53 now back where I want them in range.
1:42:55 Comprehensive lab testing of the sort that Function offers
1:42:58 is so important for health and while I've been doing
1:43:01 it for years it's always been overly complicated and expensive
1:43:04 but now with Function it's extremely easy and affordable.

1:43:15 I'm sure there are sort of standards and a lot of communication in your field
1:43:20 about you know how many follicles to try and mature if one does IVF
1:43:26 and or is pulling eggs I don't know if that's the right term forgive me there
1:43:31 it is again I you know it's pulling eggs taking eggs out carefully and for sake
1:43:37 of freezing or fertilization um but how
1:43:41 much conversation is there at the various meetings
1:43:43 and in the journals about things like
1:43:45 coenzyme Q10 L-carnitine I'm not trying to punch
1:43:48 holes in these I'm obviously a big fan of supplements and my friends joke
1:43:51 when people ask me which supplements do you take they just shout all of them
1:43:55 he takes all of them which is not true I don't take all of them
1:43:57 but I've been experimenting with them since I was in my teens and they're
1:44:00 not the be-all end-all but some work
1:44:02 so how much conversation is there about things
1:44:05 like coenzyme Q10 L-carnitine is there a consensus
1:44:09 or is there sort of a distribution
1:44:10 of old school new school and I am very curious not trying to be political
1:44:15 or politically correct whether or not this divides
1:44:18 on male female fertility docs or like
1:44:22 the culture within a field often tells us a lot so I'm not asking you
1:44:26 to throw any of your colleagues under the bus but if you have to No.
1:44:32 [laughter]
1:44:31 I will say this over the past 10 years we've seen a huge change in how we
1:44:36 talk about fertility even at meetings you know
1:44:38 the first ASRM which is the American Society for Reproductive
1:44:42 Meeting that I went to was probably 15 16 years ago and it's was so IVF heavy
1:44:48 now to be fair like the science was rapidly
1:44:51 evolving like genetic testing was just introduced for embryos
1:44:54 but as we also see more patients
1:44:57 and the general public really curious about well what can
1:45:00 I do and I think this is such a good question because I look at people and say
1:45:04 IVF is incredible but I can only work with the eggs and sperm you give me so
1:45:07 come to the table with the best eggs
1:45:09 and sperm you can right control all of these variables.
1:45:12 That public curiosity drives research to a degree
1:45:18 because if you're hearing it from your patients
1:45:20 that's the formation of research questions right what
1:45:22 we're looking at now granted all data that exists
1:45:25 is is limited in its own form right
1:45:27 in general we look at cohort studies of course
1:45:29 people who tend to take CoQ10 have other
1:45:32 advantageous lifestyle factors than people who do not.
1:45:35 When we do randomized control trials though which
1:45:37 we often do in the IVF subset because we
1:45:39 can look at more distinct criteria I can
1:45:42 say well how many how many eggs were mature
1:45:45 or how many embryos formed or how many were
1:45:47 genetically normal or the pregnancy rate per embryo transfer
1:45:51 which is a little bit of a finer point
1:45:52 than just how many people got pregnant per month.
1:45:55 We definitely see robust data that certain supplementation CoQ10 vitamin
1:45:59 D omega-3 fatty acids those are clearly associated with improved
1:46:03 reproductive outcomes and I we're starting to see more I
1:46:06 don't want to say fringe but of the specifics right inositol
1:46:09 for PCOS decreases insulin resistance
1:46:11 huge benefit N-acetylcysteine for endometriosis
1:46:15 or chronic inflammatory disease so we're seeing more interest
1:46:19 in the nuance it's a hard question on the field I
1:46:21 think there's definitely an old school versus a new school approach.
1:46:24 I've always been slightly controversial because I've always been educating
1:46:30 I think at the end of the day my job's not
1:46:32 to say just do IVF my job's to explain what's going
1:46:35 on what the options are and help you make that decision.
1:46:40 I think a lot of older trained physicians practice
1:46:44 medicine in the day where this field specifically patients did
1:46:48 not have knowledge and access to knowledge therefore when
1:46:52 a doctor said do this they just blindly said okay
1:46:56 and they view that as a simpler way to practice
1:46:59 and therefore can be very dismissive of patient questions
1:47:02 when they are say what about CoQ10 or any any
1:47:06 merit of the other lifestyle factors that we talk about
1:47:09 the plethora of research that exists which is more
1:47:11 and more now is that these lifestyle factors matter
1:47:13 a lot that decreasing inflammation can influence your fertility
1:47:17 from a how your hormones function how your ovaries respond when
1:47:20 you're how many eggs you pull out to the what
1:47:23 you say how how many embryos you form
1:47:25 and that supplementation is one piece of the puzzle it's
1:47:29 not the end all be all I think we can probably
1:47:32 should always you know focus first on where we
1:47:35 can move the needle the biggest so those more core
1:47:38 lifestyle practices this should be tenant number one when we
1:47:42 feel like we've mastered those and we want to add
1:47:44 to the puzzle that's when we can start to say
1:47:46 what supplements help me and one thing that I
1:47:49 really encourage is allowing ourselves space in each patient
1:47:52 to be their own N-of-1 experiment meaning how can I
1:47:55 get so in tune with my body that I can say this makes me feel this way and trust
1:48:01 that sense for yourself because we are all unique
1:48:04 and our response will be different to different medications or different
1:48:07 interventions and learning to trust that and think about
1:48:11 what's working for you or oh this isn't that's really
1:48:15 important when it comes to optimizing your own health
1:48:17 regardless of what tenant of health that we're talking about.
1:48:20 If we'd been sitting here 15 years ago
1:48:22 and I said you know red light therapy can be
1:48:26 useful for skin and for offsetting age-related vision loss
1:48:31 um any reasonable physician would be like that's nonsense.
1:48:37 Um I spoke to an ophthalmologist yesterday
1:48:39 there's been a clinical trial using red
1:48:40 light and infrared light for what's called
1:48:43 dry AMD a dry macular degeneration to offset
1:48:47 age-related vision loss and it is looks
1:48:49 promising I mean it doesn't reverse age-related
1:48:51 vision loss completely but seems to help
1:48:53 the mitochondria in the photoreceptors people are holding
1:48:55 onto some vision that they would lose there was a cover of what I am
1:48:58 told is the premier dermatology journal exploring
1:49:01 the recent studies on red light and infrared
1:49:03 light so it's a common practice now so it takes time but this stuff
1:49:07 was considered super woo nation nonsense by most
1:49:12 {quote} traditional physicians 10 15 years ago.
1:49:16 In the field that you're in, how are things like red
1:49:18 light infrared light therapy looked at currently and if they are used,
1:49:25 where is it directed?
1:49:26 Mhm.
1:49:26 Is it actually on top of the ovaries?
1:49:28 Is that the idea or that it's a more of a systemic effect?
1:49:31 Great question.
1:49:33 I think again, let's just think about the fact that chronic inflammation impacts
1:49:35 your body when it comes to your hormones
1:49:37 and your fertility multiple ways, right?
1:49:39 So, if you have chronic inflammation,
1:49:41 it's going to interfere with hypothalamic receptivity.
1:49:44 So, your brain can't interpret your hormonal signals as well.
1:49:47 It's also going to send out signals differently.
1:49:49 You're also going to have distinct ovarian changes and how
1:49:52 the ovary responds and then of course for the egg quality.
1:49:55 So, the bigger answer of like what type of therapy matters maybe depends
1:49:58 on the outcome that we're looking at or how we're trying to show benefit.
1:50:01 And in short, that is inconclusive,
1:50:03 but all appears to be beneficial for the reasons you stated,
1:50:06 whether it is to improve ovulation patterns,
1:50:08 which we've seen signs showing that.
1:50:11 That's more of the systemic probably.
1:50:13 Like you're sitting in front of your red light panel,
1:50:15 that's going to decrease some whole body inflammation.
1:50:18 That's the inflammation that's most likely
1:50:19 contributing to some of the brain sensitivity.
1:50:22 So, you're improving the ovulatory pattern.
1:50:24 There have been some studies looking at ovarian directed red light therapy,
1:50:28 so through the abdomen.
1:50:29 But there is now, I mean we don't have definitive data,
1:50:31 but there's even a vaginal ultrasound wand that's got red light therapy.
1:50:35 So, we don't have data on that yet,
1:50:36 but seeing intravaginally you're much closer to the ovaries,
1:50:39 that's why we do [clears throat] vaginal ultrasound
1:50:41 monitoring for IVF to try to see if directing
1:50:45 the response closer to the ovary can have
1:50:47 more benefit or could potentially benefit egg quality more.
1:50:51 I think most people are going to say,
1:50:52 you know, we don't have definitive data yet.
1:50:55 Yet everything's pointing to likely benefit.
1:50:57 Mhm.
1:50:58 I don't know if this study could be done,
1:50:59 but um one arm of this my podcast company funds research
1:51:05 and one thing I'd love to see the experiment done is um either
1:51:10 maintaining or doing fertilization of of eggs under red light because so
1:51:15 much of the proper chromosomal arrangement
1:51:17 seem to be dependent on mitochondrial health.
1:51:19 That's a short-term exposure.
1:51:21 But um the more I learn about the different
1:51:23 wavelengths of light and how they impact mitochondria
1:51:25 and I think about the horrible lab lighting
1:51:27 that I lived under for many years of my life.
1:51:29 I think are these these such precious embryos
1:51:32 is there a way to put them under um
1:51:35 beneficial lighting as opposed to either neutral or I'm
1:51:38 not saying detrimental lighting, but I don't know.
1:51:40 It'd be a fun study to to fund if um if there's a way to do it.
1:51:43 Yeah.
1:51:43 I think it definitely could Okay.
1:51:44 I think it definitely could be done.
1:51:45 You mean we have incubators.
1:51:46 They that could definitely be done and where you fertilize, too.
1:51:50 I was going to say off topic,
1:51:51 my daughter did her science fair project on chicken eggs,
1:51:54 but they looked at blue light, green light, and natural light Ooh, cool.
1:51:59 if they, you know, they're all fertilized,
1:52:00 but to see if their hatchability was different and the group that was
1:52:04 exposed to blue light actually had the highest hatchability and you know,
1:52:07 UV light was actually the lowest.
1:52:10 But in their research,
1:52:11 what so fascinating is that red light is really detrimental to chicken eggs.
1:52:14 So, anyways, I think Yeah, well that's why science is fun.
1:52:17 Oh, congratulations to her.
1:52:18 She should write it up.
1:52:19 You know, there's a journal where kids can write up their Yeah,
1:52:22 I'll send you a link to it.
1:52:23 She'll be published and that's what's so cool about science.
1:52:26 Sometimes we think, oh the red light is going to be the beneficial one,
1:52:29 the UV light is going to or the blue light is going to be the bad one,
1:52:32 but then you know, vitamin D production is dependent on blue and UV.
1:52:36 So, you know, nature's mysterious.
1:52:38 You know, that's awesome.
1:52:40 It It keeps it interesting for us.
1:52:41 Awesome.
1:52:41 Is she going to become a scientist?
1:52:43 Or she's already a scientist, but 11, but she's a scientist right now.
1:52:46 I love it.
1:52:47 I love it.
1:52:47 I'll send you that link.
1:52:48 It'd be cool if she would write that up.
1:52:50 Um So, red light maybe.
1:52:53 Yeah.
1:52:53 And I should point out I red light and infrared comes from sunlight.
1:52:56 So, and of course there's circadian good circadian effects of getting sunlight.
1:53:01 All circadian benefits of getting sunlight are pro-fertility,
1:53:04 pro-hormonal health.
1:53:05 Yes.
1:53:06 Yeah, I don't want to give people
1:53:06 the impression that they have to purchase a panel.
1:53:09 Um there's no hidden agenda here.
1:53:11 So, those are the things that one can take that do not,
1:53:15 I think broadly as don't smoke, don't drink.
1:53:17 I was shocked, but I need to ask um to learn what I found was that 15
1:53:24 15% of women in the United States report having
1:53:28 used cannabis in some form or another while pregnant.
1:53:30 Does that concern you?
1:53:32 Cannabis use is probably the most concerning
1:53:34 thing that I see in clinical practice.
1:53:36 So, both you can just say if that many are using it in pregnancy,
1:53:40 let's extrapolate to how many are using it beforehand.
1:53:43 And ultimately something that we are just now getting robust
1:53:46 data on because it's hard to study something when it's illegal.
1:53:49 All cannabis use is hugely detrimental
1:53:51 to sperm for sure across the board, right?
1:53:53 Both production, the quantity of sperm,
1:53:56 testosterone production, also the quality of the sperm,
1:53:59 specifically the DNA fragmentation inside the head of the sperm
1:54:02 to the degree that female partners who conceive
1:54:04 from a male partner who's using cannabis have much
1:54:07 higher miscarriage rates than partners who do not utilize cannabis.
1:54:11 And I will say clinically in the IVF lab when I
1:54:13 see embryos halt at that male developmental stage on day three,
1:54:17 we say, "Oh, here's a young couple.
1:54:19 They've got no embryos and we were expecting them to have
1:54:21 some." When we go back nine out of 10 times,
1:54:24 he is using cannabis that he previously denied.
1:54:28 So, it is one of the most movable
1:54:30 factors right now in this country for improving, you know, fertility outcomes.
1:54:36 For women, cannabis use in the prior year can decrease the eggs you get at egg
1:54:40 retrieval by 25% and can decrease fertilization
1:54:44 rates by 28% and can increase miscarriage rates,
1:54:48 therefore decreasing live birth rates.
1:54:49 So, huge numbers in science, right?
1:54:52 I mean like we get excited when something's a few,
1:54:54 you know, percentage points different, but these numbers are really high.
1:54:59 To the degree that it's really easy to sit here
1:55:00 and say if you're trying to get pregnant the fastest,
1:55:03 if you want to have the best pregnancy outcomes
1:55:05 or even you want to have the best hormones you can,
1:55:09 have longevity of your ovaries or have
1:55:11 the best sperm counts or the most testosterone,
1:55:13 cannabis use should not be a part of that.
1:55:16 And THC crosses the placenta directly.
1:55:19 And THC levels in, you know, edibles are usually the highest.
1:55:22 So, I think it's really important that sometimes people are like,
1:55:24 "Oh, well I don't smoke it, so I'm okay." We want to be really careful
1:55:29 that this is not something your body is meant
1:55:33 to be exposed to when we want to think about
1:55:35 the core of how your body is meant to function.
1:55:38 Critical message.
1:55:39 Thank you so much.
1:55:39 I I've been put through the ringer around this cannabis thing cuz I've hosted
1:55:43 people that said it does increase the risk
1:55:45 of psychosis in certain typically young males, although not everyone.
1:55:49 I've been accused of all sorts of things related to that, then
1:55:53 had someone on who confirmed that, someone who refuted it and um
1:55:56 cannabis I believe is recently rescheduled from schedule one no
1:56:01 at the federal level it's assigned to no medical application to schedule three.
1:56:07 So, there's going to be a lot more cannabis use going forward.
1:56:09 It's so critical that people hear this.
1:56:11 And the argument I always hear and it's always dudes typically on X,
1:56:15 they'll say um that they smoked a lot of weed and they
1:56:19 got their or took edibles and they got their wife or girlfriend
1:56:22 pregnant X number of times and it sort of becomes this sort
1:56:25 of point of boasting and then I never want to make the comment,
1:56:27 but I'll make it now.
1:56:28 It's like, "Yeah, but you're talking about brain development
1:56:31 in your kid." And I'm not saying your kid is dumb,
1:56:34 but I'm saying they're maybe not as smart as they
1:56:35 could be or as um healthy as they could be.
1:56:39 I'll just say that cuz I'm talking to the guys
1:56:40 out there and that's how we talk to one another.
1:56:43 Yeah, you had a bunch of kids, but they could be a lot healthier.
1:56:45 And so, I think to me it just seems like anything that one
1:56:48 could do since it's a ostensibly
1:56:51 a short-term decision certainly for the man, right?
1:56:54 The woman who's going to breastfeed
1:56:56 should probably avoid cannabis during breastfeeding, too.
1:56:58 You see where I'm going with this.
1:56:59 The outcome is so important, right?
1:57:01 And when we want to think about even just male cannabis use.
1:57:04 Yes, sperm count, etc.
1:57:07 Decreases the sperm quality.
1:57:08 That sperm quality is important for programming
1:57:10 of the embryo for how the placenta develops.
1:57:12 If the placenta is not as good, you know, association with earlier birth.
1:57:16 I mean, it's just not worth the risk when the outcome is so important, right?
1:57:22 We're all weighing risk every day with different decisions.
1:57:25 To me, there's a lot harder decisions you have to make,
1:57:27 but you know, nicotine use, cannabis use, alcohol use, like the data here,
1:57:33 none of that is advantageous for your health,
1:57:35 especially if we're looking primarily through a fertility lens,
1:57:38 a hormone lens, or even or [clears throat] specifically a pregnancy lens.
1:57:42 Like there's there's no place for it.
1:57:44 You can choose to do what you want with that data, right?
1:57:46 And people will always say, "I know so-and-so who did this and they
1:57:50 got pregnant." And there will always be those people.
1:57:52 But you're the one making decisions for your journey.
1:57:55 And the recommendation even stronger if you
1:57:57 are having infertility, if you are older,
1:58:00 depending on your scenario because you want to control
1:58:03 what you can because you can't control everything.
1:58:06 So, I call those the behavioral toxins that there's
1:58:08 really no place that we need to add these to the world if we're talking about
1:58:11 how do we get my body to function optimally.
1:58:14 It's interesting that um certain substances get politicized.
1:58:19 You know, in the past experience this thing
1:58:22 that you can tell with some degree of friction.
1:58:25 Um in the past cannabis was associated with the left.
1:58:28 It was like pro-cannabis was left.
1:58:29 Now, pro-cannabis is actually very strongly correlated with the
1:58:33 with the with the um the laws anyway this rescheduling is
1:58:37 very and you watch the media just kind of pivot and it's
1:58:40 just very clear that they're not paying that the media is
1:58:43 in the traditional media isn't paying attention to the to the actual data.
1:58:47 It's sort of like, "How can we use this as a weapon?" On both sides.
1:58:50 On both sides.
1:58:51 And so, depending on where people get their news,
1:58:53 it can be very confusing to people um along those lines.
1:58:58 For whatever reason,
1:58:59 nicotine has become kind of this right-wing associated thing.
1:59:02 I know.
1:59:03 I recently spoke to about 4,000 young men and women and I would say about
1:59:08 30 to 40% of them raised their hand
1:59:10 that they're using oral nicotine every single day
1:59:14 anywhere from probably I did I did some
1:59:17 crude analysis by hand so these aren't you
1:59:20 know hard data but it was somewhere between 12 and 70 mg of nicotine a day.
1:59:28 Wild.
1:59:28 So for women in particular is oral nicotine use
1:59:33 detrimental to either egg quality or probability of successful pregnancy?
1:59:38 It's definitely correlated because of how it works
1:59:41 in the brain to you know ovulation getting pregnant hormone response.
1:59:45 So it should not be something that we're adding to you know
1:59:49 our day-to-day life in any form if we're trying to get pregnant.
1:59:53 Most the egg quality data from nicotine comes from cigarette smoking so
1:59:56 I think it's a little bit more nuanced because smoking directly we want
2:00:00 to look at that you know I would say it's one
2:00:02 of the few things that gets into the vault and decreases our egg count.
2:00:05 I used to say chronic inflammation can get
2:00:06 in there but you know nicotine cigarette smoking definitely does.
2:00:10 You go into menopause early you'll get
2:00:12 fewer eggs the egg quality is detrimental.
2:00:15 It makes sense based on what nicotine does to your body
2:00:18 and how it kind of changes your cellular response that it probably
2:00:21 is impacting your egg quality also even with these oral nicotine pouches
2:00:25 you know that we're seeing everybody utilize and it's tanking sperm counts.
2:00:29 I mean that one's really clear.
2:00:32 I mean then it of course everyone's talking about the reduction in in uh
2:00:36 in just population growth which when I was growing up we were told
2:00:40 that like the earth is going to be overcrowded now we're told that there's
2:00:43 not going to be enough people everyone's going to be alone on their phones.
2:00:45 I don't think either extreme is true um
2:00:48 but these are these are vitally important things
2:00:50 for people to think about cuz these are easy
2:00:52 decisions to make and they can be short-term decisions.
2:00:54 They are.
2:00:54 You know we make decisions every day and and you don't have to be perfect
2:00:57 and you don't have to be all or nothing and it doesn't have to be forever.
2:01:01 A lot of these things once you really start making
2:01:04 a bunch of them and decreasing inflammation you will tangibly feel better.
2:01:08 I think we are creatures of our own world and humans
2:01:11 by nature adjust to the environment we put our body into.
2:01:15 So even things like we talked about sleep
2:01:16 but you know chronic stress how it's directly associated
2:01:19 with insulin resistance how building skeletal muscle is one
2:01:23 of the top ways you can reverse insulin resistance.
2:01:25 It's the best mechanism for hormonal health
2:01:28 we have is to build more skeletal muscle.
2:01:31 These things can impact your fertility and your health long-term.
2:01:35 And so once we start to make these little
2:01:37 decisions eating more fiber anti-inflammatory
2:01:39 foods cutting down the ultra-processed
2:01:40 foods removing the toxins changing the toxic behaviors sleeping more
2:01:45 really trying to manage stress in a more productive way.
2:01:49 Together when your inflammatory burden lowers people feel
2:01:52 better and then they get it then they say oh like this running on just caffeine
2:01:57 and eating whatever food I could on the go
2:01:59 and not getting enough sleep and then using
2:02:02 100 nicotine like that was my body giving
2:02:05 me 100 red flags that it is working overtime to deal with what I'm handing it.
2:02:10 So how's it supposed to do its normal day-to-day
2:02:12 function which at its purest that's where your body should
2:02:16 try to be especially when it comes to trying
2:02:18 to get pregnant and have the best egg and sperm quality.
2:02:21 I would never ask you to assign any validity to something for which there's
2:02:24 no data but in your experience
2:02:27 your clinical and scientific experience is there something
2:02:31 that you've heard from your patients and then
2:02:32 observed in terms of outcomes that is
2:02:35 intriguing to you that if that you would like to see more science on?
2:02:39 Um and the reason I ask this is is there's this um incredible
2:02:43 intuition that comes from just being in regular contact with a certain process.
2:02:48 For instance anytime I've spoken to an embryologist who does the kind of work
2:02:52 that they do in your clinic they read
2:02:54 journals and there's a process they learn protocols
2:02:56 but they also they develop an intuition to pick that sperm to wait just a little
2:03:01 bit longer maybe even maybe even fertilizing that egg at the end of the day
2:03:05 Oh I know it's a couple of hours.
2:03:07 It's a little small it's a little this this is the this is the art not
2:03:10 je ne sais quoi Right right the art not the science
2:03:12 of it the same way you know cooking is chemistry
2:03:15 but there's an art to it too and that nothing
2:03:18 can replace those millions of hours in contact with the process.
2:03:22 So you've had so many hours in this process at every level.
2:03:26 Um is there something that intrigues you
2:03:27 and that you'd like to see more science on?
2:03:30 I love that question.
2:03:32 One thing I think I want most people to take away then I'll
2:03:35 answer the question is that you can make tangible improvement in your fertility.
2:03:41 By looking at these lifestyle factors and coming up
2:03:43 with a plan to try to decrease your inflammatory
2:03:46 burden you can have a different outcome and I
2:03:48 think that conversation's even more important if you're waiting
2:03:51 longer to get pregnant or if you're at an older
2:03:53 age or you have lower ovarian reserve because
2:03:55 knowing that you are controlling all these variables to put
2:03:57 the best egg and sperm forward is really important.
2:04:01 The most intriguing part of the conversation for me right now
2:04:03 is GLP-1s and their use
2:04:06 for potential chronic inflammatory disease like endometriosis.
2:04:10 As a field we quickly accepted that they are hugely powerful for PCOS
2:04:14 and states of obvious insulin resistance
2:04:16 for reasons that make sense to everybody.
2:04:18 They also help obviously patients lose weight.
2:04:22 Fat cells make estrogen they impact the ovulatory process.
2:04:25 Fat cells are inflammatory.
2:04:27 So all the things that we said were negative.
2:04:28 So by simply losing weight we can restore ovulation we can have improved
2:04:32 IVF outcomes and it is just a more effective mechanism for weight loss.
2:04:37 So easy to jump on and say I have a patient who needs to lose weight.
2:04:42 I have a patient with PCOS GLP-1 agonist can be a very powerful tool to that.
2:04:47 Where I see right now are patients who have known
2:04:49 endometriosis or what I call probable endo they have unexplained infertility.
2:04:54 50% of those patients will end up having endometriosis.
2:04:57 Maybe you know one of the problems with endo
2:05:00 is gold standard is a surgical diagnosis only.
2:05:03 We don't have a lab test for endometriosis.
2:05:06 But when we are getting unexplained IVF outcomes that do not match what
2:05:10 we would expect or we have these known chronic inflammatory diseases I will
2:05:14 have patients go on a GLP-1 low dose for 3 months we should
2:05:20 take stop them and then go through a cycle with different IVF outcomes.
2:05:24 We will see more embryos in the lab and we don't have
2:05:26 to study to say that but talking to colleagues across the country
2:05:31 we know that GLP-1s can be very anti-inflammatory and the way
2:05:36 to kind of target that what appears to be that inflammatory burden
2:05:40 and I think that there will be utility there within the context
2:05:44 of these chronic inflammatory disease that might be able to help
2:05:47 a patient population that we've struggled with with difficulty to get
2:05:50 to a diagnosis or limited data points on what to do with it.
2:05:55 So the data's not out yet but it is a tool I add to the box
2:05:59 especially if we're not getting outcomes we would
2:06:01 expect and we don't have another reason why.
2:06:04 So do you think there could be direct effects of the GLP-1s
2:06:06 in reducing inflammation that are independent of less adipose tissue?
2:06:11 some of these patients do not have much adipose tissue.
2:06:13 So I think obviously that person's going to get
2:06:17 even more benefit if they have adipose tissue
2:06:19 to lose that's causing inflammation but I think
2:06:21 especially if we think about autoimmune disease where people's
2:06:25 immune system their inflammatory response is mistriggering I think
2:06:30 that there's benefit for the GLP-1s in that population
2:06:32 specifically that is giving them an added benefit
2:06:36 to decrease inflammation in a really profound way.
2:06:39 It's really interesting cuz I would have
2:06:40 thought GLP-1s reducing body fat for a woman
2:06:45 who doesn't isn't carrying excess body fat
2:06:47 that might actually be detrimental to getting pregnant.
2:06:49 fair point that we have to be really careful when it comes to skinny culture.
2:06:55 I mean we are seeing just societal norms shift again to be very
2:06:59 thin after being more you know body body positive be of a healthy weight.
2:07:03 We're definitely seeing celebrities go back to being extremely thin and we
2:07:07 know at both extremes of body weight again the hypothalamus is your checkpoint.
2:07:10 If you don't have enough body fat we are worried that you
2:07:14 cannot maintain a pregnancy so it can stop how it's sending
2:07:17 off hormones and again we can see like a luteal phase
2:07:20 defect is that first warning sign before you're in true hypothalamic amenorrhea.
2:07:24 So you have to be really careful in that patient group and it has to be
2:07:27 done with the right person who's a lot
2:07:29 of experience with GLP-1s are super low doses.
2:07:31 The goal is not weight loss it's really a different goal.
2:07:35 And again I don't have a paper to like prove it
2:07:37 but we are seeing that clinical experience to say at the end
2:07:41 of the day because there's merit in trying to decrease inflammation especially
2:07:44 in people who we suspect is contributing to the circumstance they are in.
2:07:48 And you said low dose GLP.
2:07:50 Yeah.
2:07:50 Yeah.
2:07:50 Are these available in generic form now or they just
2:07:53 still are they still under patent where they have to be
2:07:55 know the answer to that one.
2:07:56 Okay.
2:07:57 I don't know I know compounding pharmacies are making them.
2:07:59 I know today today the gray market for peptides in this country was shut down
2:08:04 so no more you can no longer buy that just for research purposes but compounding
2:08:08 pharmacies seem to be protected but I just asked because of the GLPs at least
2:08:14 the non-generic forms in their full dosage
2:08:16 my understanding is that they can be rather expensive.
2:08:19 Yes.
2:08:20 But the lower dosages from in generic form perhaps are
2:08:24 more for I would I have to be more affordable.
2:08:26 One would think yeah and I think again these add-on or there's
2:08:29 a lot of kitchen sink approach we do in fertility medicine right?
2:08:32 I've used human growth hormone for years and years and years right?
2:08:35 There's no FDA approval to use HGH for egg quality.
2:08:39 Yet we see that it can improve egg quality in the right patient in the lab.
2:08:42 So if somebody has a cycle and they don't get as many mature eggs
2:08:46 or their embryos don't do as well my partner actually did a study where she put
2:08:50 them through the same protocol so the same
2:08:52 medications in a subsequent cycle and the only
2:08:54 change was adding human growth hormone and had
2:08:57 improved embryo development and maturity of eggs.
2:08:59 Amazing.
2:09:00 So it's like an IUI night or something like that.
2:09:02 Like some low dose of of HGH during during that.
2:09:05 I see.
2:09:05 Just during the stems.
2:09:06 So it's like 2 weeks of use.
2:09:07 And so then now that's starting to be extrapolated and people
2:09:09 are starting to look at it longer or before stem.
2:09:13 You know, and so we have to take that I
2:09:15 love the fact that my field's always viewed cutting edge research.
2:09:19 You know, it's a double-edged sword.
2:09:20 Like there's some good and there's some bad.
2:09:22 We really want to think about mechanistically
2:09:24 if it could potentially help having, you know,
2:09:26 a low threshold to attempt it in patients who
2:09:28 are getting at the end of their journey specifically, right?
2:09:31 When they've they've done all the basics.
2:09:32 They're controlling the lifestyle factors.
2:09:34 I will say one thing I dislike is this just do IVF mentality,
2:09:39 meaning nothing you can do can impact your egg quality.
2:09:42 Let's just do IVF and then we're compounding dollars and dollars and dollars.
2:09:47 Yet we're not eating anti-inflammatory food and we're drinking
2:09:50 wine every night and we're not getting enough sleep, right?
2:09:52 Like so I think that we've got to really look at these, you know,
2:09:57 five non-negotiable areas and optimize them to the degree
2:10:00 we can knowing each day will be different,
2:10:02 but building our body the resilience to be
2:10:04 able to respond as it's appropriate to.
2:10:06 Cuz sometimes you'll fly to Texas and get less
2:10:09 sleep or you'll go out to eat and, you know,
2:10:11 you'll eat differently and your body's meant to handle those challenges,
2:10:14 but it can't when it's constantly challenged every
2:10:17 single day all the moments of the day.
2:10:19 So there's a ton of experimental stuff that we do that's really
2:10:22 cool and some of it will be introduced into practice in 10 years.
2:10:26 You know, probably 15 years ago if I had said human growth hormone,
2:10:29 people would have scoffed and now it's commonly added on when we're
2:10:33 not getting the outcome we want and that's how medicine should be.
2:10:36 We should not be afraid to say that the perfect study
2:10:39 doesn't have to exist if it physi- the physiology makes sense,
2:10:43 if there's suggested studies, if we explain it to the patients,
2:10:48 we help have shared decision-making with them because
2:10:50 if we're always waiting for the perfect RCT,
2:10:54 there will be thousands of patients we could
2:10:55 have helped in the interim that we didn't.
2:10:58 What are your thoughts on platelet-rich plasma?
2:11:00 Oh, such a good question.
2:11:02 Which is not stem cells, by the way.
2:11:03 Sorry to to just shout out there.
2:11:05 People think it's stem cells.
2:11:06 Stem cells are not allowed by the FDA in the United States.
2:11:10 A vision clinic, they were injecting them into the eye for macular degeneration
2:11:14 and the patients all went blind and I'm very familiar with those cases.
2:11:17 It was that specific clinic that shut down stem cell.
2:11:20 You can't advertise stem cells online anymore.
2:11:23 So now they just P- but PRP is not stem cells.
2:11:25 Forgive forgive me for interrupting.
2:11:27 PRP has two potential different mechanisms by which
2:11:30 it can be used and it's different.
2:11:32 So one is intrauterine PRP,
2:11:34 where we are injecting it into the uterine cavity similar to how
2:11:37 we put an embryo inside or how you would do an intrauterine insemination.
2:11:41 So small catheter, not invasive,
2:11:43 just but kind of goes through the cervix right into the uterus.
2:11:46 The other is looking at ovarian PRP, which is a more invasive procedure.
2:11:51 This is using the same needle like we do for IVF.
2:11:54 Yet instead of extracting the follicular fluid and the eggs,
2:11:57 I'm putting the PRP into the ovaries.
2:12:00 Looking at it for two different reasons,
2:12:02 implantation failure or potential Asherman's scarring of the uterus
2:12:06 in the uterine PRP group and looking at it for, you know,
2:12:10 low ovarian reserve or age-related fertility in the PRP of the ovary group.
2:12:16 Where it shows the most promise is intrauterine PRP.
2:12:18 So which is nice because it's less invasive.
2:12:22 That's the minority of people who are having recurrent implantation failure.
2:12:27 You know, most people don't have success because they don't make enough embryos.
2:12:31 That's the rate-limiting step for most people with IVF.
2:12:33 Meaning if you have three genetically normal embryos,
2:12:35 almost 95% of people will have a live birth.
2:12:38 So we're talking about a very small subset of the population here,
2:12:41 but showing the most promise though
2:12:43 not universally accepted and isn't done everywhere.
2:12:46 Ovarian PRP is a little bit more nuanced
2:12:49 because clinics can charge a lot for it.
2:12:53 It's a procedure.
2:12:54 You need anesthesia.
2:12:56 I'm putting a needle in the ovary.
2:12:57 I'm always a lot more skeptical of potentially damaging the ovary or, you know,
2:13:04 potential developing eggs.
2:13:05 Although no study has supported that it does do that.
2:13:08 There are some more hypothetical concerns with that versus uterine,
2:13:13 where you're not really damaging any structure, you're just adding it.
2:13:16 That being said, ovarian PRP is currently being studied.
2:13:18 We don't have definitive data.
2:13:20 Potentially could be something to consider
2:13:22 if you're really approaching that end game.
2:13:23 You know, you're [clears throat] really not getting the outcome you want.
2:13:25 You are older.
2:13:26 You have low ovarian reserve.
2:13:28 There are people who have some success stories.
2:13:30 So I think it's again the exception, not the rule.
2:13:34 Has potential benefit, but yet to be determined.
2:13:38 A few years back, uh there were some more discussion
2:13:40 about the age of the sperm and the probability of autism.
2:13:44 Yes.
2:13:45 Could you update me on the the uh the data?
2:13:48 Yeah, after age 50, we see a few different increases for sperm specifically.
2:13:52 So advanced paternal age is real both when it comes to how you make sperm,
2:13:56 but also the quality of that sperm.
2:13:58 We see overall on a population base increases of autism,
2:14:02 of autosomal dominant new mutations,
2:14:05 specifically certain types of like dwarfism or very specific um
2:14:10 diseases that are ultimately overall rare that can can happen.
2:14:14 And then you also can see an increase
2:14:15 in some other mental health diseases like schizophrenia.
2:14:19 That data is scary.
2:14:21 Not the end-all, be-all.
2:14:22 At the end of the day, when you have an opportunity to bank sperm younger,
2:14:27 it would make sense and utilize that preferentially.
2:14:30 You know, if somebody came to me and let's say they had banked
2:14:33 sperm and it's gone now and I have a 52-year-old man across from me.
2:14:37 I mean, this is who we want to have children with, then this is who we want
2:14:40 to have children with and we accept that risk
2:14:42 cuz on a population so very low, right?
2:14:44 A small percentage point increase means still the most probable
2:14:48 chance is you're going to have a very healthy baby.
2:14:51 It plays more into the the idea that nobody's fertility is finite,
2:14:56 that, you know, age-related impacts impact everybody.
2:14:59 I would say the same thing is that if the mechanism
2:15:01 is the the DNA essentially or the quality of the sperm,
2:15:05 then those lifestyle tenants in the 90 days prior to getting
2:15:09 sperm or banking it or using it in IVF cycle probably matter
2:15:13 the most and I would make sure I would want to be
2:15:14 controlling all of those factors I was so I wasn't adding to risk.
2:15:19 No cannabis, reduced heat, um all the things that mutate DNA.
2:15:24 Exactly.
2:15:23 Yeah.
2:15:23 Nicotine out, that kind of thing.
2:15:25 Um yeah, it's interesting.
2:15:27 I I think about the the sort of high signal to noise anecdotes.
2:15:32 Um things like, oh, you know,
2:15:35 um so-and-so smoked weed every day and has eight kids or uh you know,
2:15:39 or or um you know, so-and-so had kids
2:15:42 when he had another kid when he was whatever.
2:15:45 I'm thinking of some actors or something that I don't follow this stuff closely.
2:15:48 He was when he was like 78 or something.
2:15:50 The the problem with stories like that is
2:15:52 that they they grab people's attention cuz they're
2:15:55 high signal to noise and they distract
2:15:57 from the stuff that like really matters to most everybody.
2:16:01 Like freezing eggs is not going to take
2:16:04 more eggs out of your reserve than you need.
2:16:05 The NSAIDs, I mean, I'm just like still wide-eyed about this NSAID thing.
2:16:09 It's something to avoid while trying to get pregnant.
2:16:11 do another one.
2:16:12 Uh biotin levels of taking a biotin
2:16:15 supplementation of 300 micrograms or more for 7
2:16:19 days can actually influence your lab assays
2:16:22 for sex hormones or for any steroid hormone, actually.
2:16:26 So when I will sometimes see patients who are going through an IVF
2:16:28 cycle and their estradiol levels are not
2:16:30 matching what we're seeing for follicular development,
2:16:33 if we go and talk to them and they're taking hair,
2:16:35 skin, and nail supplements or something with a high
2:16:37 dose of biotin because commercial supplementa- like you know,
2:16:41 there's certain very popular hair supplements that have,
2:16:44 you know, 10 to 30 times that amount in them.
2:16:47 These is binding to the lab test.
2:16:50 So we're getting false reads on these labs.
2:16:53 Not changing in your body,
2:16:55 but it actually This is an REI board question, an oral board question.
2:16:57 Is that it binds to the steroid assay.
2:16:59 So this can happen to estradiol,
2:17:01 to progesterone, to HCG, to TSH, to testosterone.
2:17:05 So if you are back where we started and you want to get data about your body,
2:17:08 maybe you feel off or you're going through IVF
2:17:11 or you want to get a hormone panel done,
2:17:13 if you're taking a supplement that has more than 300 micrograms of biotin,
2:17:16 you're going to have results that are inaccurate and we cannot trust.
2:17:19 So really making sure that you're looking
2:17:21 at what's in your supplements and biotin is
2:17:23 that specific one that I want to make sure we're not taking excess amounts of.
2:17:27 Wow.
2:17:28 Um as long as we're talking about things that people take or put on their body,
2:17:31 uh the last time we sat down and spoke,
2:17:33 we had a conversation about endocrine disruptors.
2:17:35 people really loved and hated us for that.
2:17:37 I will say cuz it's tricky with comments.
2:17:39 Again, signal to noise.
2:17:40 I think many, many more,
2:17:41 meaning millions of people appreciated it as opposed to had issues with it.
2:17:46 I mean, it is you can tell how frustrated I get
2:17:48 with with My frustration is not with medicine or with science.
2:17:52 It's with the um lack of open ears Mhm.
2:17:55 in a certain generation of of physicians and scientists.
2:17:58 I mean, my colleagues at Stanford are very open-minded.
2:18:00 And by the way, many of them call me saying like, what should I take for this?
2:18:04 Or like, I love that.
2:18:04 I do that's not TRT for testosterone?
2:18:06 And like I mean, it's they're humans, too.
2:18:09 And I think the issue around endocrine disruptors for the longest
2:18:13 time was seen as kind of hippie science with no data.
2:18:17 And then now, because the Environmental Working Group
2:18:20 started getting really vocal about this and Shanna Swan,
2:18:22 who's, you know, a long-time researcher.
2:18:23 Yeah.
2:18:24 Um but then there was this sort of political backlash because somehow people
2:18:28 decided to slot her and the Environmental
2:18:30 Working Group as kind of anti-standard science.
2:18:33 You sit down with her, this is far the thing from the truth.
2:18:35 Like she's all about data.
2:18:37 So I think as we toe into this uh you know, endocrine disruptor thing, I mean,
2:18:43 I'll just say it for you and then if you if you want to add,
2:18:45 like none of what we're about
2:18:47 to talk about negates anything about standard medicine.
2:18:50 It's just way ways and places to be uh
2:18:53 additionally cautious about things that you are around and might
2:18:57 You make decisions every day.
2:18:59 You should be making it from a place of knowledge.
2:19:01 And the things that you're exposed to more frequently matter the most, right?
2:19:05 So a one-time exposure cuz you used hand soap and it had lavender,
2:19:09 tea tree oil, or whatever, I'm much less concerned about than the products you
2:19:13 buy for your home that you're using every single day.
2:19:16 Because when it comes to endocrine disruptors,
2:19:18 a lot of it is the quantity of exposure that really adds up and this typically
2:19:21 comes from frequency because typically it's low
2:19:24 levels in a variety of different products.
2:19:26 But they absolutely can disrupt hormone function.
2:19:29 They cause longer time to pregnancy.
2:19:31 There's now been robust data looking at, you know,
2:19:34 one of the biggest cohort studies we have and it's, you know,
2:19:36 called the Earth study where they're looking at different
2:19:38 environmental compounds on reproductive health and they're looking
2:19:42 at cohorts of people trying to get pregnant naturally
2:19:44 and they did a sub-study looking at endocrine disrupting
2:19:46 chemicals specifically of those people who went on to do
2:19:49 IVF and showed that those who had higher
2:19:52 levels of endocrine disrupting chemicals had a harder time
2:19:55 getting pregnant even with IVF and their IVF markers,
2:19:58 fewer eggs retrieved, fewer embryos, poorer sperm counts.
2:20:02 So it's definitely not hippie science at this point.
2:20:04 It's well demonstrated that it impacts our bodies in multiple ways.
2:20:08 And as I recall, the things to be cautious of are lavender,
2:20:11 evening primrose, or basically anything with a scent.
2:20:14 Essential oils for the most part tend to be fine, but it is lavender,
2:20:18 tea tree, and evening primrose that have more endocrine properties for them.
2:20:23 When it comes to other products, scented products have a lot of phthalates
2:20:26 in them and then that's an endocrine disrupting chemical.
2:20:29 And an important note here,
2:20:30 which is wild to me because we see so much greenwashing
2:20:33 on products where they'll slap a label on it and they'll say unscented.
2:20:38 But unscented is a scent to mask other scents.
2:20:43 Really?
2:20:44 So unscented just means you've masked a scent.
2:20:46 What you really want to look for is fragrance-free
2:20:48 because fragrance-free means we added no fragrance to it.
2:20:51 To be called unscented,
2:20:53 we could have added something to counter the fragrance that was in it.
2:20:57 Amazing.
2:20:57 Amazing.
2:20:58 And Uber drivers?
2:21:00 I'm not saying riding in your Uber with your terrible air freshener
2:21:02 is going to prevent people from getting
2:21:04 pregnant or conceiving with their partner,
2:21:06 but um take the freshener out of your Uber
2:21:10 cuz you might not be able to have children.
2:21:12 Yeah, no, I was saying for the drivers are the ones exposed to it the most.
2:21:15 these things, you know, another like one of the top exposures
2:21:18 of BPA right now is actually thermal paper.
2:21:20 So receipts.
2:21:21 So think about receipts at the grocery store or the airline counter.
2:21:24 So for one of them, you know,
2:21:27 getting it one time and touching it is probably not a big deal.
2:21:30 But for the people who are do that job
2:21:31 and are exposed all the time to thermal paper,
2:21:34 that actually can be such a high level exposure.
2:21:37 So it's a good example where I say you need to use gloves if
2:21:39 you that's your industry that you're going to be exposed to thermal paper a lot.
2:21:43 So same thing for it, let's say the Uber driver.
2:21:46 This is what you're spending your time doing,
2:21:48 you don't need that fragrance for your own health and certainly we don't want
2:21:52 to get in the Uber with I know I'm so mean if this smells,
2:21:55 I'll like I'll I'll star them lower which because
2:21:58 it's like I think you should know, you know.
2:22:00 You're paying for a service.
2:22:02 I mean, I usually roll the window down, stick my head out the window.
2:22:04 If they're coughing, I hate being sick and I'm like I didn't pay to get sick.
2:22:07 So I I try to be polite about it, but you know,
2:22:11 there's just But again, we control the things we can, right?
2:22:14 So let's control the fragrance in our home
2:22:16 and in our products because to your point, we can't control what's in the Uber.
2:22:20 And so we're not going to stress about it and that's the argument I get number
2:22:22 one is that you're causing people to be
2:22:24 stressed about toxins that otherwise they wouldn't be.
2:22:28 And I again, like that's paternalistic.
2:22:30 Like toxins are impactful to your health.
2:22:32 I should give you the data so that you can cultivate the day-to-day life
2:22:35 that is to the degree where you don't stress about it when you're on the plane
2:22:39 or you're in an Uber or you're at a party because that one-off isn't such
2:22:43 a big deal because you're not exposed
2:22:45 to it every single day inside of your home.
2:22:47 I like to think that people want information.
2:22:51 Um I realize they can feel overwhelmed by too much information, but in the end,
2:22:55 even though what we're talking about here seems
2:22:56 like a lot of to-dos and not to dos, it there's a logic to it.
2:23:00 I think the logical backbone is you do what you can.
2:23:03 Um you do your best to control the the key variables.
2:23:06 Um I mean, the point about cannabis I think is really important
2:23:09 that especially men hear um because I think most people don't know.
2:23:13 And women don't know they should get their AMH checked.
2:23:15 I mean, that's changing because of people
2:23:17 like you being out there doing public education,
2:23:19 but I like to think that people want knowledge.
2:23:21 I really do.
2:23:22 I actually think people do want knowledge and I
2:23:24 don't think they're the ones giving the counterargument, to be honest, right?
2:23:27 I think it's our colleagues who say, "Oh,
2:23:30 people don't want to hear that." Or they make assumptions.
2:23:32 And again, in today's world where we have data,
2:23:34 like why are we talking about assumptions?
2:23:35 Let's give people data and let them make the choices they make.
2:23:39 Yeah, ignorance is not bliss when you're running up against a health challenge.
2:23:43 Yeah, if you haven't had your own health challenge,
2:23:45 maybe it's hard to understand what it is.
2:23:47 And for infertility for most people,
2:23:49 this is their first time their health is really being challenged,
2:23:52 usually because of the age range of which it is.
2:23:55 I mean, that was my story.
2:23:56 A decade later, I got diagnosed with celiac
2:23:58 disease despite having unexplained recurrent pregnancy loss.
2:24:03 I can tell you that this can, you know,
2:24:05 colliding with my fertility fellowship when I advocated
2:24:08 for doing vitamin research and all this epidemiology,
2:24:11 I saw the word inflammation in all of that text,
2:24:13 yet we weren't talking about it with our patients.
2:24:16 And I went on this journey to get rid of Teflon in our kitchens.
2:24:20 I studied PFCs and we changed the foods that we ate,
2:24:22 changed how we exercised and how we slept.
2:24:26 And one of the things that I cut out learning
2:24:28 to listen to my body was gluten at the time.
2:24:30 Even though I would have never said I had like GI symptoms from it.
2:24:33 I just said, "Oh, I felt more inflamed." Like vague symptoms,
2:24:37 kind of headache, kind of more fatigued.
2:24:40 And when I conceived my children before we ever had to do IVF,
2:24:43 we got pregnant naturally in that time period when I didn't have gluten.
2:24:48 So decade later, I get the diagnosis that was
2:24:52 actually contributing to why we had these different pregnancy losses.
2:24:55 So it wasn't unexplained at all.
2:24:57 And not that everybody needs to cut gluten out,
2:24:59 but understanding how chronic inflammation impacts our bodies
2:25:03 and learning to listen to our body
2:25:06 is one of the most powerful tools that we have and it starts with, you know,
2:25:11 education and knowledge, learning how to advocate for ourselves, right?
2:25:14 When you know what's normal, you can sit in front of somebody and say
2:25:17 this isn't normal and mean it with your full heart.
2:25:20 And then how do you optimize all the things at home?
2:25:23 Cuz back to the other point, even if you need IVF,
2:25:26 I can only work with the eggs and sperm you give me.
2:25:28 And maybe if we're focusing on some of the stuff earlier,
2:25:31 there's probably a subset of people who can
2:25:33 get pregnant without IVF or who can freeze eggs
2:25:36 and have an easier journey because they had
2:25:38 this information and they made choices based off of it.
2:25:40 What I'm realizing hearing you today is that we need to listen to our bodies.
2:25:44 Women need to listen to their bodies
2:25:45 cuz we're mainly talking about women's health here.
2:25:47 Men do too, but we're talking about women.
2:25:49 But also learn to be scientists of our bodies.
2:25:52 Yes.
2:25:52 And when it comes to nutrition, I'm very curious because of your example,
2:25:56 do you think there's any value
2:25:58 to people experimenting with a quote-unquote cleaner diet
2:26:03 if for no other reason than to figure out which ingredients don't work for them?
2:26:07 Meaning, if you have granola for breakfast and a side of eggs and some toast
2:26:11 or one day you have eggs and the next day you have toast or both, whatever.
2:26:15 And then for lunch you're having a sandwich and then for dinner
2:26:17 you're having some pasta with some sauce and you don't feel well.
2:26:21 You don't know what the problem is.
2:26:22 So I'm not advocating for, you know, a Spartan diet where it's like, you know,
2:26:25 chicken breast next to rice next to broccoli
2:26:28 with a tablespoon of olive oil next to it, although that sounds pretty okay.
2:26:32 There's worse.
2:26:33 There's worse.
2:26:34 But when you eat that way for a short period of time,
2:26:38 that sort of cleaner and more or less individual ingredients, Mhm.
2:26:42 I do think that you can get insight into what works
2:26:44 for you and what doesn't independent of all the other information out there.
2:26:48 Like for instance, there's certain forms of fibrous foods,
2:26:50 I definitely believe in fiber, that I just don't feel well.
2:26:53 Yeah.
2:26:53 And then my sister, who is not a scientist,
2:26:56 um she'll chuckle at that, but she had this intuition about histamine Mhm.
2:27:00 that has now been confirmed by two guests on this podcast
2:27:03 who are MD PhDs who work on these sorts of issues.
2:27:07 Um in one case, pain, in other case, gut inflammation.
2:27:09 And she was convinced that she had some
2:27:11 histaminergic thing that she read about in some book.
2:27:14 Suggests I take this histamine enzyme tablet before I eat and it's
2:27:19 opened up this whole array of other foods that I can eat.
2:27:21 But for years I would get super sleepy after I would eat certain foods.
2:27:24 I'm like, "This makes no sense.
2:27:25 I like starches.
2:27:26 I like fiber." Turns out I have a sort
2:27:28 of mild histamine sensitivity to like four different foods.
2:27:32 I don't think you can figure that out unless you separate out the ingredients.
2:27:36 Absolutely.
2:27:36 It's like I planted this question for you
2:27:38 even though I didn't because I advocate,
2:27:40 especially if you are falling off the curve, right?
2:27:43 I think if you're trying to learn to listen to your body, you say,
2:27:46 "I want to optimize my own health." For a very
2:27:49 temporary but restricted clean eating pattern where you're having lots
2:27:52 of fruits and vegetables and fiber and you're cutting down
2:27:55 some of the things that cause more commonly cause certain reactions,
2:27:59 cutting out gluten, cutting out dairy, cutting back on red meat.
2:28:02 And then you add them back in and start
2:28:04 to listen to how your body is functioning.
2:28:06 But you have to really kind of eliminate first
2:28:08 and then you can add back and see, "Oh,
2:28:10 I feel better, worse, the same." Okay, well,
2:28:13 if it's worse, that's maybe not something you should have.
2:28:15 And then learn to listen for it.
2:28:17 The tenets of a fertility diet are really not eye-opening, right?
2:28:21 Fiber is hugely important for the gut microbiome
2:28:23 and hormone health and inflammation and insulin resistance.
2:28:25 So high fruits and vegetables, high fiber diet,
2:28:28 whole grain carbohydrates over your refined carbohydrates,
2:28:31 ultra-processed foods don't have a place in the modern diet,
2:28:34 added artificial sugars, those non-nutritive sweeteners,
2:28:37 they don't have a place in this.
2:28:39 We want to have quality of our protein.
2:28:41 Most people could benefit from some increased plant protein due
2:28:44 to the increased fiber than they actually get in the standard American diet,
2:28:48 but meat is not universally bad nor necessarily good.
2:28:51 It's the quality of the meat that probably matters a lot.
2:28:54 The meat data to notice is
2:28:55 that for every serving of plant-based protein over animal,
2:28:57 people tended to ovulate better and had higher fertility rates.
2:29:01 Probably more suggestive of an overall healthier fiber
2:29:04 first dietary pattern on the population base level
2:29:08 because ultra-processed foods don't have a lot
2:29:11 of fiber in them or any fiber in them.
2:29:13 Animal-based products don't have fiber in them,
2:29:15 so we want to be mindful of that ratio.
2:29:17 Red meat's the really controversial one and increased servings of red meat,
2:29:21 of course, dietary studies quartile it lowest exposure, highest exposure.
2:29:26 Highest exposure groups had poor embryos develop,
2:29:29 worse outcomes with IVF and an increase
2:29:32 in staging of endometriosis when they went to surgery.
2:29:35 That doesn't mean to me that all red meat is bad,
2:29:37 but it probably is for a subset of people more inflammatory, causes more IGF-1.
2:29:42 We want to be mindful of it.
2:29:43 The question I always get is does source matter?
2:29:46 I mean, probably, but we weren't looking at it in any of those studies.
2:29:49 So, I think being very mindful of where your animal-based protein
2:29:53 is coming from is really important in today's kind of food world.
2:29:58 Not all foods are created equal even when they fall into the same category.
2:30:02 And it's worth saying that healthy fats are really, really important, right?
2:30:05 Cholesterol's the backbone for steroid hormones,
2:30:07 so you need cholesterol in your body.
2:30:09 So, we really want to encourage those mono-unsaturated,
2:30:12 poly-unsaturated fatty acids.
2:30:14 So, the nuts, olive oil, fish, algae, chia seeds, flax,
2:30:19 those things have such so many benefits when
2:30:22 it comes to the omega-3 fatty acids they have,
2:30:25 but also that they're great healthy sources of cholesterol,
2:30:27 which your body needs.
2:30:29 And in fact, if you don't intake enough,
2:30:31 you're not going to make progesterone as well.
2:30:32 It'll be really minute.
2:30:33 You need progesterone for implantation,
2:30:35 don't have enough unsaturated fat in your diet,
2:30:37 you're not going to make as much progesterone.
2:30:39 So, there's some nuance there, but to the heart of your question,
2:30:43 I'm a huge advocate for that especially if
2:30:45 you're struggling with something you're not feeling your best,
2:30:48 if you say you kind of hit the marker
2:30:50 on a lot of these inflammatory symptoms and you don't know
2:30:52 what's going on, it can be a really helpful tool
2:30:56 once you're controlling the other ones to try to leverage.
2:30:58 But again, sleep, stress, building muscle, avoiding those excess toxins,
2:31:03 like those are huge piece of the puzzle, too.
2:31:06 And a lot of them go hand in hand, right?
2:31:07 A lot of times we eat a food that's also wrapped in something that has,
2:31:12 you know, toxic chemicals in it.
2:31:14 So, we really want to think about the fact that when you work from home,
2:31:17 when you have access, whole foods and is really important
2:31:21 as always leveraging processed or ultra-processed versions.
2:31:25 Would you say that uh what you just described, in fact,
2:31:27 everything we talked about, um also pertains to perimenopause, menopause?
2:31:32 Absolutely, absolutely.
2:31:32 It's so fascinating cuz when I sit with a lot
2:31:34 of people who just do menopause, you know,
2:31:36 we have the same recommendations for lifestyle
2:31:39 and decreasing inflammation because it's going to improve,
2:31:42 you know, ovarian response,
2:31:43 it's going to improve how your body feels, decreasing inflammation.
2:31:47 We know that when you go into menopause,
2:31:49 estrogen has such profound anti-inflammatory benefits that one
2:31:52 of the biggest problems is a baseline increase in your inflammation.
2:31:56 So, don't wait till you're in perimenopause
2:31:58 or menopause to start to learn these things.
2:32:00 Learn them whatever play point you are now is the perfect time
2:32:04 where we can start to make a difference both for hormonal health now,
2:32:07 fertility now or later, but also your ovarian function long term.
2:32:12 Amazing.
2:32:13 Uh Dr.
2:32:14 Natalie Crawford, thank you so, so much.
2:32:17 I mean, I can't tell you how much I
2:32:19 learn every time you speak on this podcast and elsewhere.
2:32:22 People should definitely get your book.
2:32:24 Again, I've read it.
2:32:25 I've read it cover to cover.
2:32:27 Um The Fertility Formula, Take Control of Your Reproductive Future,
2:32:30 Natalie Crawford, MD, did all the training, runs the clinic,
2:32:34 is out there doing public education amidst everything else, managing,
2:32:39 co-managing a family, um and just really expanding the field.
2:32:44 I mean, you're taking it in new directions,
2:32:45 which is really the to me the most important thing, right?
2:32:48 That you're out there teaching people, but you're also going back to the clinic
2:32:51 and you're paying attention to the science
2:32:53 and evolving the science because this field is just going to improve over time,
2:32:57 but you've given people so many actionable things to contemplate,
2:33:02 to definitely do, if I may insert my own uh beliefs there,
2:33:06 and just a lot to think about in terms of the general landscape
2:33:10 of how we think about reproductive health both our own and and societally.
2:33:13 So, thank you so much for coming back.
2:33:15 We will do it again if you're willing, and um just grateful to you.

2:34:14 It's entitled Protocols, An Operating Manual for the Human Body.

2:34:19 years and that's based on more than 30 years of research and experience.
2:34:24 And it covers protocols for everything from sleep to exercise to stress control,
2:34:29 protocols related to focus and motivation.
2:34:32 And of course, I provide the scientific
2:34:34 substantiation for the protocols that are included.
