Female Hormone Health, PCOS, Endometriosis, Fertility & Breast Cancer | Dr. Thaïs Aliabadi

Imagine someone with cataracts seeing twenty eye doctors and being told nothing is wrong; that’s how women with infertility from PCOS or endometriosis are treated every day, and it’s why I’m here to change that.

Welcome to the Huberman Lab podcast, where we share science and practical tools; today I’m joined by Dr. Thaïs Aliabadi to tackle PCOS, endometriosis, fertility, breast cancer screening, and the often-missed signs that affect women’s health across the lifespan.

Given rising concern about fertility and delayed childbearing, is the standard age-versus-fertility curve even valid if so many women with PCOS or endometriosis are never identified?

Those curves mislead because undiagnosed PCOS and endometriosis quietly drain egg quality and sometimes egg number, so we need early screening for both and routine egg-count testing with AMH even in symptomatic teens.

I’ve operated on severe endometriosis in teenagers, and I see twenty-somethings told they’re “too young” for evaluation while their reserves crash; catch this early and many IVF cycles could be avoided.

Health education should teach PCOS and endometriosis early; with that in mind, what exactly is PCOS?

PCOS is the most common hormonal disorder of reproductive-age women and it’s massively underdiagnosed; you meet the diagnosis by having two of these three: symptoms of high androgens like acne or excess hair or hair thinning, irregular or unpredictable cycles, or ovaries that look polycystic on ultrasound or a high AMH.

Blood testosterone can be normal and you can still have PCOS, which is why so many are missed, and birth control alone is not a treatment plan even though it can reduce symptoms.

Irregular periods can be hard to judge in young people; how should teens be evaluated?

Be cautious labeling teens because early cycles are naturally erratic and their ovaries are follicle-rich, so diagnose based on irregular cycles plus androgen symptoms and avoid using ultrasound morphology or AMH in that age group while treating the pattern you see.

Is this diagnostic confusion evenly spread across the OB-GYN field, and should pelvic ultrasound be standard care?

Most patients go undiagnosed partly because pelvic ultrasound is not done routinely and many clinicians mistake the name to mean visible cysts; a proper pelvic ultrasound should be part of every well-woman exam.

Names matter, and “cystic” can mislead, but changing the label could also reset public awareness.

I oppose renaming because the hard-won recognition of PCOS would be set back just as it’s gaining traction.

How can someone tell if mild acne or some hair thinning points to PCOS, and does it vary across the cycle?

Persistent adult acne or clear scalp thinning plus a history of weight struggle, mood symptoms, or repeated hair removal is a pattern worth evaluating, and symptoms are typically steady rather than cyclical.

PCOS has four phenotypes, so some women have regular periods or normal-looking ovaries yet still do not ovulate reliably, which is why pattern recognition matters more than any single feature.

Are antidepressants causing PCOS or is that a separate issue, and what drives the mood symptoms?

Antidepressants are not causing PCOS; the mood issues stem from hormone-brain interactions and from living with untreated symptoms, so we have to address the biology underneath.

At the core, the brain–pituitary–ovary rhythm speeds up, driving LH higher than FSH, which pushes the ovarian theca cells to make androgens that stall follicles, block ovulation, and still feed the uterine lining so bleeding can occur without true ovulation.

So many will bleed and assume they’re ovulating when they’re not; that’s important for fertility planning.

Only about a quarter ovulate consistently, and even then egg quality and the uterine environment can be suboptimal, which lowers conception rates.

We know stress can alter hypothalamic function, but is PCOS mainly stress-driven or something broader?

PCOS is a multisystem condition with a genetic base and a major pillar of insulin resistance that also appears in lean women, and excess androgens themselves worsen insulin resistance.

High insulin further boosts ovarian androgen output, lowers sex hormone binding globulin so free androgens rise, and diverts blood sugar into triglycerides and visceral fat that inflame the body and promote more insulin resistance.

Add chronic inflammation, gut symptoms, family patterns like a diabetic father, and epigenetics such as sleep, nutrition, and stress, and you see why mood, weight, and cycle issues cluster and why dismissal harms.

You mentioned follicles shrinking under high androgens in both hair and ovary, and I’m also thinking of women in their thirties told they’re fine until IVF reveals problems.

AMH can look great in PCOS because many small arrested follicles secrete it, but count is not quality, and a quick rule is AMH of one maps to roughly ten follicles while unusually high counts at forty often signal PCOS.

For PCOS I advise considering egg freezing sooner for quality, because I often see large egg yields at older ages that fail to make viable embryos.

Access is also an issue, and sometimes technology might triage better than busy clinics, though great clinicians are irreplaceable.

Half of counties in the United States lack an OB-GYN, so scalable tools and even AI triage could prevent years of dismissal while we expand high-quality care.

There’s pushback on hormone contraception lately; where does it fit for PCOS?

Pills can ease symptoms by raising sex hormone binding globulin and making cycles predictable, but they’re rarely my first choice in PCOS because many feel worse on them and they don’t fix the drivers.

I start with sleep, walking after meals, reducing processed foods, stress control, vitamin D, and inositol, then add metformin at effective doses like seven hundred fifty milligrams twice daily and up if needed.

Vitamin D and sunlight matter for metabolism, and inositol has different forms; how about GLP-1s and berberine?

I’ve used GLP-1s since 2014 and they reliably improve insulin handling, reduce inflammation, help weight loss, and often restore more regular cycles in this population.

Berberine can be a short-term tool but I don’t keep patients on it long term; metformin and supplements with vitamin D and inositol are more sustainable.

People now microdose GLP-1s through compounding to avoid nausea, and many report fewer cravings and better mood along with metabolic benefits.

GLP-1s quiet the relentless food noise and even reduce alcohol cravings, which lets patients finally feel in control rather than battling urges all day.

Diagnosis and proper treatment restore confidence, so if you’re gaining weight, breaking out, shedding hair, struggling to conceive, or cycling irregularly, you are not imagining it.

For those wanting pregnancy, what’s your approach before referring to IVF?

I optimize insulin resistance and inflammation with supplements and metformin, then induce ovulation with letrozole first and clomiphene second, and most couples who time intercourse a few times per week conceive within a year if both partners are otherwise healthy.

If that fails or age is a factor, I refer to fertility care, and I also see endometriosis coexisting with PCOS in well over half my cases, so pain and other signs must not be ignored.

People can use your zero-cost OVII risk tools to get oriented, and supplements like CoQ10 and L-carnitine may support egg quality, especially when inflammation is part of the picture.

There isn’t a single definitive blood test for PCOS, so learn the phenotypes and the fact that many do not ovulate even with regular bleeding, and remember that time-limited visits and myths like “normal testosterone means no PCOS” are why so many go untreated.

The first lever people can pull on their own is insulin sensitivity, with sunlight, good sleep, less stress, smart nutrition, exercise, and supplements like inositol, CoQ10, and L‑carnitine.

I built OV for women at home who suspect PCOS and feel lost; start with the quiz, clean up sleep, food, and stress, take the supplement, and if you want kids later, freeze eggs early and know your egg count.

Should women over 30 still freeze eggs?

Yes; PCOS often means many follicles, so bank aggressively because quality can lag, which is why I aim for around twenty eggs when young and far more as age advances.

Costs and yields get worse with age, and after early forties it can be low probability and pricey.

Exactly, paying tens of thousands for a cycle that yields a couple eggs rarely makes sense.

I want every listener, including men for the sake of the women in their lives, to help spread this; women deserve to hear their pain is real and to be their own health advocate.

Self‑advocacy is rising, and I hope you get even more reach with this message.

Quick recap before endometriosis: take the OVI self‑test, improve insulin sensitivity with sleep, stress control, diet, and training, and consider the supplement with inositol and CoQ10.

We also included vitamin D and mulberry leaf, which taken before the heaviest meal can blunt carbohydrate absorption substantially; many feel mood benefits once root issues improve, sometimes before needing antidepressants.

What is endometriosis, what problems does it cause, and what can be done?

It’s tissue like the uterine lining growing outside the uterus that bleeds internally each cycle, often on ovaries, tubes, bladder, or bowel, and it’s far more common than reported.

So it’s internal bleeding in the wrong place.

Yes, and the tragedy is delayed diagnosis from dismissal; there’s no blood test, and careful listening is the most accurate screen—painful periods that disrupt life are not normal.

How do you distinguish normal cramps from pathologic pain?

If pain alters daily life, triggers ER visits, causes bowel or bladder pain, bloating, or recurrent negative‑culture UTIs, assume endometriosis; it’s a leading cause of chronic pelvic pain and infertility and often leads to misdirected opioid use.

An equivalent male condition would be treated as urgent, no question.

Exactly, and years of dismissal leave deep scars; I see people in midlife who lost jobs, relationships, and hope, just needing someone to validate the diagnosis.

Many doctors care, but the system rushes visits and fragments expertise.

Mechanisms likely include menstrual backflow and an immune response that fails to clear cells and instead helps them adhere and inflame tissues.

Normally immune cells should clear it.

In endo they promote adhesion, local estrogen production, new blood vessels, and nerve ingrowth, so lesions behave cancer‑like without being cancer; excision must be followed by hormonal suppression or it returns.

How does it affect IVF outcomes?

It scars tubes, damages eggs, forms ovarian cysts that reduce reserve, and creates a hostile inflammatory environment that raises risks of failed fertilization, ectopic pregnancy, and miscarriage; adenomyosis often coexists and is missed.

Can women get ultrasound and AMH covered, or is access impossible?

Insurance usually covers, but symptoms get normalized and time is short, so ask directly for AMH and pelvic ultrasound and remember normal imaging does not rule out endometriosis.

What’s the definitive approach?

Laparoscopic excision is the gold standard; cautery is temporary, few surgeons are truly trained, and stromal disease looks subtle and is often missed, which is why so many get told they don’t have it.

Do we know the cause, and is it increasing?

There are several theories and I see strong overlap with PCOS via chronic inflammation; it’s not rare and likely affects well over one in five.

Patients know their bodies; women in particular track internal changes closely and should be believed.

When a woman says something’s wrong she’s almost always right, and writing it off as anxiety is harmful.

How would you fix care?

Separate obstetrics from gynecology so surgeons can focus and have time, and expand the well‑woman visit beyond a Pap and mammogram to true preventive and fertility health with imaging and labs.

For treatment, what should people and clinicians consider first?

Use progesterone‑only pills or a progesterone IUD to suppress lesions, avoid added estrogen, and consider GnRH antagonist pills for pain from deep disease, knowing they can cause temporary menopausal symptoms and are time‑limited; after excision I place a progesterone IUD and may add those agents for months to reduce recurrence; stage never predicts pain, and stromal disease often needs cutting.

Is pregnancy protective?

Symptoms usually quiet during pregnancy, and I place a progesterone IUD postpartum to keep it suppressed.

Is postpartum depression more common, and is it related?

Risk is higher with anxiety, PTSD, PMDD, PCOS, and endometriosis, and many women face wave after wave from menarche through perimenopause while being dismissed.

Where do fibroids fit in?

They’re very common, and location drives symptoms; treat if they cause heavy bleeding, anemia, infertility, or pressure, with myomectomy if preserving fertility or hysterectomy if not, and always assess with pelvic ultrasound.

Can a woman insist on ultrasound and an endometriosis workup?

Yes, bring a clear list and ask for imaging or an order to a radiology center; a pelvic ultrasound should be routine.

How do you structure an infertility workup?

Check the woman’s hormones and egg count, the partner’s semen, the anatomy by imaging and tubal patency, screen for endometriosis and PCOS, and consider autoimmunity because clotting and immune issues can cause losses and are treatable.

You wanted to cover breast cancer risk.

Every woman should calculate lifetime risk with the Tyrer‑Cuzick tool; average risk is about twelve and a half percent, and at or above twenty percent you start imaging at thirty and add ultrasound or MRI for dense breasts; genetics and polygenic scores can raise risk and change care, and very high risk can justify alternating imaging, tamoxifen to halve risk over ten years, or prophylactic mastectomy.

You have a personal example.

After atypia my score was thirty‑seven percent, I pushed for preventive mastectomy despite resistance, and hidden cancer was found on pathology; self‑advocacy and comprehensive visits are why I haven’t lost a patient to cancer under my care.

Audience question: are there non‑invasive tests for endometriosis in menstrual blood?

Research is active, but for now listening, ultrasound, and MRI for deep disease are the best non‑invasive tools, with surgery still definitive.

Is menopause‑related brain fog inevitable?

Not always, but it’s common and often improves with hormone therapy.

What’s the most missed cause of infertility?

Undiagnosed endometriosis and PCOS.

Suggestions for PMDD for someone in their forties?

PMDD is a severe, repeating sensitivity of the brain to normal hormone shifts: about ten days before a period until a few days after, mood, energy, and relationships can crash, and suicide risk goes up.

Short, luteal‑phase SSRIs like fluoxetine twenty milligrams or sertraline twenty‑five milligrams can be game‑changing; always screen for underlying anxiety or depression, and in the forties consider whether perimenopause and hormone therapy are part of the picture.

That was incredibly clear; can we address fasting and low‑starch diets?

Food choices matter, but a strict no‑carb plan is hard to sustain; fix insulin resistance with nutrition, movement, sleep, and stress tools so PCOS and weight improve without starvation.

If someone on an estradiol patch notices hair loss, is there another option?

It’s usually hair thinning from the estrogen drop of peri or menopause, not the patch; start minoxidil early, topical or low‑dose oral beginning around 0.5 milligrams daily, expect signs of regrowth by six months and bigger gains by two years.

How can women improve egg quality after age thirty‑five?

Work the basics we covered—optimize metabolism, sleep, and inflammation, and treat PCOS or endometriosis—because egg quality reflects the overall ovarian environment.

Endometriosis and adenomyosis often respond well to a progesterone IUD, and while menopause quiets pain, giving estrogen alone can reactivate implants in a group already at slightly higher ovarian cancer risk.

Even after hysterectomy, endometriosis patients on estrogen should also receive progesterone, which can also help sleep and anxiety.

In PCOS, improving insulin sensitivity and lowering visceral fat restores ovulation and your own progesterone; in perimenopause, use micronized progesterone when appropriate.

Briefly, how does diet shape female hormone health?

Insulin resistance tends to rise as menopause approaches; genes set the stage, and daily habits—nutrition, activity, sleep, and stress—drive where hormone health goes.

What can women do to prolong fertility?

Do not ignore PCOS or endometriosis, know your egg count, and, if possible, freeze eggs earlier.

I’m profoundly grateful for your time and the practical depth you shared, from clear self‑advocacy to tools that can reduce pain, protect fertility, and support cancer detection; we’ll link to your resources and your GMD podcast, and I hope you’ll return soon.

Please join me in thanking Dr. Aliabadi through her channels.

Thank you for the mic and the chance to champion women’s health; I’m surrounded by women at home, and I do this for them and for a world that gets better when we care for women.
