Female Hormone Health: PCOS, Endometriosis, Fertility & Breast Cancer
Summary
Dr. Thaïs Aliabadi, a board-certified OB/GYN with 30 years of clinical experience, discusses why PCOS and endometriosis — the two leading causes of female infertility — go undiagnosed in the vast majority of women. She outlines the underlying biological mechanisms, the multi-pillar treatment approach, and why dismissing women’s symptoms as normal or psychological has created a widespread fertility crisis. The conversation covers diagnostic criteria, insulin resistance, hormone pathways, and practical interventions ranging from supplements to GLP-1 medications.
Key Takeaways
- 90% of women with PCOS or endometriosis are never properly diagnosed, even by OB/GYNs — making patient self-education critical
- PCOS requires only 2 out of 3 diagnostic criteria to be met; a normal testosterone blood test does NOT rule it out
- A very high AMH does not mean good fertility — in PCOS, elevated AMH reflects frozen, non-ovulating follicles with poor egg quality
- 80% of PCOS patients have insulin resistance, even lean ones; addressing insulin is the central treatment target
- Supplements including inositol, vitamin D, chromium, and curcumin can meaningfully improve PCOS symptoms, especially for those without medical access
- Metformin (750mg twice daily, titrated up slowly) is a key pharmaceutical tool for improving insulin sensitivity in PCOS
- GLP-1 medications have been used effectively for PCOS since 2014 — not just for weight loss, but for regulating insulin, reducing inflammation, and restoring ovulation
- Women with endometriosis can have the ovarian reserve of a 40-year-old at age 14 — early screening is essential
- A pelvic ultrasound should be mandatory in well-woman exams; many OB/GYNs currently skip it entirely
- Egg freezing is ideally done by age 28–30, especially in PCOS patients, despite seemingly high egg counts
Detailed Notes
The Scale of the Problem
- PCOS affects 15% of women in the US (over 20% in some Middle Eastern populations)
- An estimated 70–90% of cases go undiagnosed or undertreated
- Women’s symptoms — painful periods, mood changes, hair thinning, weight gain — are routinely dismissed as normal or psychological
- Many women only receive a diagnosis when they arrive at a fertility clinic, by which point significant damage to egg quality or ovarian reserve may have occurred
- 50% of US counties have no OB/GYN, making self-education and telemedicine critical
Understanding Female Fertility Basics
- Women are born with millions of eggs and do not produce new ones
- Egg count and quality decline with age; at menopause, approximately 1,000 eggs remain
- The standard age-based fertility curve is misleading because it does not account for undiagnosed PCOS or endometriosis
- AMH (anti-Müllerian hormone): A simple, mostly insurance-covered blood test measuring ovarian reserve
- Normal range up to ~6 in the 20s–30s
- Drops below 1 in the 40s
- Rule of thumb: every 0.1 of AMH ≈ 1 follicle
- A 40-year-old with AMH producing 30 follicles almost certainly has PCOS
PCOS: Diagnostic Criteria
Diagnosis requires 2 of the following 3 criteria:
- Symptoms of elevated androgens: facial/body hair, acne, oily skin, male-pattern hair thinning
- Ovulatory dysfunction: irregular periods (cycles >35 days, or fewer than 8 periods/year)
- PCOS morphology on ultrasound: 20+ follicles in a “string of pearls” pattern, OR elevated AMH (added as a criterion in 2023)
Important clarifications:
- A normal testosterone blood level does NOT rule out PCOS
- Polycystic ovary syndrome does not mean ovarian cysts — the name is misleading
- For teenagers, only criteria 1 and 2 apply (ultrasound morphology and AMH are not used diagnostically in adolescents)
- 70–80% of PCOS patients do not ovulate, even when they appear to have regular cycles (the bleeding is estrogen withdrawal, not true ovulatory cycling)
Four PCOS Phenotypes:
- Type A (Classic): All three criteria met
- Type B: High androgens + irregular periods, normal ovaries on ultrasound
- Type C (Ovulatory PCOS): PCOS ovaries + high androgen symptoms, but regular (or semi-regular) cycles
- Type D: No androgen symptoms; only irregular ovulation + PCOS ovaries on ultrasound
The Underlying Pillars of PCOS
1. Brain–Pituitary–Ovary Axis Dysregulation
- In healthy cycles: GnRH → FSH → follicle growth → estrogen peak → LH surge → ovulation → progesterone release
- In PCOS: GnRH pulses too rapidly, shifting the FSH/LH balance so LH dominates
- Excess LH stimulates theca cells in the ovary to overproduce androgens
- High androgens freeze follicles before ovulation can occur — creating the characteristic “string of pearls”
2. Insulin Resistance
- Present in 80% of PCOS patients, including lean women
- High androgens from the ovaries make cells more insulin resistant
- Excess insulin → stimulates ovaries to produce more androgens (a vicious cycle)
- Excess insulin → suppresses sex hormone-binding globulin (SHBG) in the liver → more free testosterone
- Excess insulin → glucose stored as fat → visceral fat accumulation
3. Chronic Inflammation
- Visceral fat releases cytokines that worsen inflammation
- Chronic inflammation → more androgen production → worse insulin resistance
- Contributes to GI symptoms, food sensitivities, and bloating common in PCOS
4. Genetics
- Family history of diabetes, pre-diabetes, gestational diabetes, or obesity on either parent’s side is relevant
- “Your genes load the gun; your environment pulls the trigger”
5. Epigenetics / Lifestyle
- Poor sleep, high stress, processed food diet, and lack of exercise all activate the genetic predisposition
- These are modifiable factors that form the first line of treatment
PCOS Treatment Protocol
Step 1 — Lifestyle (epigenetic pillars):
- Walk 10–15 minutes after each meal
- Reduce refined carbohydrates and processed foods
- Prioritize sleep and stress management
- Resistance exercise
Step 2 — Supplements (especially for those without medical access):
- Inositol (specifically myo-inositol and D-chiro-inositol): Improves insulin sensitivity, can restore regular ovulation
- Vitamin D: Deficiency worsens insulin resistance; supplementation helps
- Chromium: Supports insulin signaling
- Curcumin: Anti-inflammatory
- Dr. Aliabadi developed a supplement called OV and a free assessment tool at ovi.com
Step 3 — Metformin:
- Mechanism: Improves insulin sensitivity, clears glucose from the blood into cells
- Starting dose: 750mg at night, increase to 750mg twice daily if tolerated
- Can increase to 1,000mg twice daily if needed
- Common side effects: nausea, diarrhea (start low, titrate slowly)
- 500mg once daily is generally insufficient for PCOS
Step 4 — GLP-1 Receptor Agonists:
- Used by Dr. Aliabadi for PCOS since 2014 (initially trulicity/dulaglutide)
- Mechanism: Regulates insulin spiking after meals, improves insulin sensitivity, reduces visceral fat and inflammation
- Average outcome
