Reproductive markers reveal critical insights into systemic longevity and cellular health
How Women Can Improve Their Fertility & Hormone Health | Dr. Natalie Crawford
Understanding reproductive markers allows women to assess their broader cellular health, longevity, and hormonal wellness beyond family planning.
- 1Ovarian health markers like anti-Mullerian hormone provide essential clues about overall systemic aging and cellular vitality.
- 2Daily environmental exposures and dietary choices directly influence egg quality and long-term hormonal balance.
- 3Proactive fertility tracking serves as a powerful diagnostic tool for broader metabolic and cardiovascular wellness.

Dr. Natalie Crawford explains how tracking ovarian reserve serves as a vital diagnostic window into a woman's overall biological age.
The brief
Reproductive markers are not just about family planning; they serve as a critical window into a woman's overall cellular health, systemic longevity, and biological aging.
Dr. Natalie Crawford explains that metrics like anti-Mullerian hormone levels offer vital diagnostic clues, yet true fertility optimization requires managing daily lifestyle stressors.
From the science of egg quality to the hidden impact of environmental toxins and diet, subtle daily choices directly shape ovarian reserve and hormonal balance over time.

Fertility reflects hormonal, cellular, and metabolic health.
“Fertility is a health marker.”
Listen at 4:03
Infertility is associated with higher risks of several diseases and early death.
“if you have infertility, you have increased rates of metabolic syndrome, cancer, heart attack, stroke, and dying early.”

Listen at 5:58
Women should not have to wait twelve months without periods before considering hormone therapy.
“I think it's a disservice to women to make them have no period ovarian failure for 12 months, no estrogen, feel terrible before we'll allow them to have hormone replacement therapy.”
Listen at 8:02
Hormone therapy may protect cardiovascular, cognitive, and bone health.
“for women, we see it be cardio protective. It can help lower the risk of Alzheimer's disease. Of course it can be protective for your bones.”
Listen at 10:39
Reducing chronic inflammation may extend ovarian lifespan.
“cultivating a lifestyle that's decreasing inflammation. Right. Avoiding certain toxins, eating anti inflammatory foods, the type of exercise, and how we deal with those lifestyle tenants that that likely has the capability to extend our ovarian lifespan to the degree that it can.”
Listen at 18:56
Microplastics can accumulate in the ovaries.
“when it comes to microplastics, as you mentioned, we know they can accumulate in the ovary.”
Listen at 20:23
Plastic endocrine disruptors are associated with poorer IVF and pregnancy outcomes.
“some of the endocrine disrupting chemicals that are in plastics have been associated with worse IVF outcomes, lower live birth rates, longer time to pregnancy.”
Listen at 20:49
Monthly natural fecundability declines to about 5% at 38 and 3% after 40.
“At age 38, it'll be 5% per month. And at 40 and beyond, it'll be 3% per month.”
Listen at 24:13
Infertility care should become more proactive rather than requiring patients to fail first.
“we have to switch how we approach infertility.”
Listen at 26:29
Previous childbirth statistically increases the chance of subsequent conception.
“there is data that having a child previously puts you statistically at a higher chance of getting pregnant again.”
Listen at 26:58
People should receive evaluation after two pregnancy losses.
“after two pregnancy losses, you need an evaluation.”
Listen at 34:49
No direct clinical test currently measures egg quality.
“We don't have a direct test for egg quality.”
Listen at 46:48
Women should obtain AMH testing to understand their reproductive timeline.
“Everybody should get an amh.”
Listen at 52:05
A luteal phase shorter than eleven days can signal ovulatory dysfunction despite regular cycles.
“Less than 11 days is a short luteal phase, but you'll still have regular cycles.”
Listen at 54:02
AMH testing costs approximately $79 out of pocket.
“We're withholding a $79 test.”
Listen at 56:06
IVF and egg freezing do not reduce ovarian reserve.
“doing IVF or egg freezing is not going to decrease your ovarian reserve.”
Listen at 1:02:40
Egg freezing involves attrition: roughly 90% survive thaw, 75% fertilize, and 50% reach implantation stage.
“90% of eggs survive the freeze, thaw, 75% will fertilize, 50% will make it to the implantation stage.”
Listen at 1:13:20
A genetically normal embryo has approximately a 65% live-birth probability.
“even a genetically normal embryo only has a 65% chance of live birth.”
Listen at 1:13:32
Contraceptive use does not increase infertility rates by twelve months after discontinuation.
“No higher rate of infertility, again defined as failure to get pregnant at 12 months.”
Listen at 1:22:14
A single Depo-Provera injection can suppress ovulation for up to eighteen months.
“one single dose can prevent ovulation for 18 months.”
Listen at 1:27:05
Pregnancy termination does not appear to reduce later fertility.
“No study supports that having a termination is going to negatively impact your fertility later.”
Listen at 1:27:28
NSAIDs taken around ovulation can prevent follicular rupture.
“if women take NSAIDs around the time of ovulation, Advil, Ibuprofen, Aleve, they'll prevent the follicle from rupturing.”
Listen at 1:30:37
Poor sleep is associated with approximately twice the infertility rate.
“if you say you have poor sleep, you have double the rate of infertility.”
Listen at 1:34:46
Low-dose melatonin before bedtime may improve conception odds and egg quality.
“doses of 1-3mg 30 minutes before you go to bed can improve your odds of getting pregnant as well, can influence egg quality.”
Listen at 1:36:10
Cold plunges should generally be avoided while trying to conceive.
“I'm not a fan of cold plunges when trying to get pregnant.”
Listen at 1:38:24
People trying to conceive should consider CoQ10, omega-3 fatty acids, and vitamin D.
“we should take CoQ10. We should take omega 3 fatty acids. We should take vitamin D.”
Listen at 1:41:30
Prior-year cannabis use may reduce retrieved eggs and fertilization rates.
“Cannabis use in the prior year can decrease the eggs, you get at egg retrieval by 25% and can decrease fertilization rates by 28%”
Listen at 1:54:36
Nicotine, cannabis, and alcohol use are not beneficial for fertility or health.
“nicotine use, cannabis use, alcohol use, like the data here, none of that is advantageous for your health.”
Listen at 1:57:29
Cigarette smoking accelerates menopause, lowers egg count, and harms egg quality.
“nicotine, cigarette smoking definitely does. You go into menopause early, you'll get fewer eggs. The egg quality is detrimental.”
Listen at 2:00:08
GLP-1 drugs may help chronic inflammatory fertility conditions such as endometriosis.
“The most intriguing part of the conversation for me right now is GLP1s and their UN use for potential chronic inflammatory disease like endometriosis”
Listen at 2:04:01
Very low or high body weight can impair reproductive hormone function and pregnancy maintenance.
“We know at both extremes of body weight, again the hypothalamus is your checkpoint. If you don't have enough body fat, we are worried that you cannot maintain a pregnancy”
Listen at 2:07:07
Paternal age above fifty is associated with increased sperm-related reproductive risks.
“After age 50, we see a few different increases for sperm specifically.”
Listen at 2:13:48
High-dose biotin can distort sex-hormone and steroid-hormone laboratory assays.
“Taking a biotin supplementation of 300 micrograms or more for seven days can actually influence your lab assays for sex hormones or for any steroid hormone actually.”
Listen at 2:16:14
Higher endocrine-disruptor exposure is associated with poorer natural and IVF fertility outcomes.
“those who had higher levels of endocrine disrupting chemicals had a harder time getting pregnant even with IVF and their IVF markers. Fewer eggs retrieved, fewer embryo, poorer sperm counts.”
Listen at 2:19:51
Consumers should choose fragrance-free rather than merely unscented products.
“What you really want to look for is fragrance free. Because fragrance free means we added no fragrance to it.”
Listen at 2:20:46
Replacing animal protein with plant protein is associated with better ovulation and fertility.
“for every serving of plant based protein over animal, people tended to ovulate better and had higher fertility rates.”
Listen at 2:28:56
