Stacy Sims, Natalie Crawford, Mary Claire Haver & Vonda Wright — A panel of four top women's-health experts: Stacy Sims (exercise physiologist/sports-med researcher), Natalie Crawford (fertility doctor/reproductive endocrinologist), Mary Claire Haver (OBGYN and menopause specialist) and Vonda Wright (orthopedic sports surgeon and aging/longevity researcher), with over 80 years' combined experience.
The gist
Host Steven Bartlett convenes four female-health experts to explain why women's bodies have been understudied and women's symptoms routinely dismissed. The conversation walks through the menstrual cycle as a vital sign, hormones as the body's communication system, and conditions like PCOS and endometriosis driven by insulin resistance and chronic inflammation. They cover contraception trade-offs, iron deficiency, fertility decline with age and the case for egg freezing, and the realities of miscarriage and postpartum recovery. The back half focuses on perimenopause and menopause, the harm of low estrogen, and hormone therapy as one tool among lifestyle changes, plus how employers can better support women.
Big reveals
- Women weren't required to be represented in US research studies until 1993.
- Infertility is linked to an 80% higher chance of heart attack and 75% higher chance of metabolic syndrome later in life.
- Team member Liv took 7 years to get an endometriosis diagnosis after 17 years of pain, with a 4cm endometrioma found at surgery.
- Bartlett reveals interviewing UFC fighter Ronda Rousey after her seventh failed IVF round pushed him to consider egg freezing.
- Experts assert 50% of infertility is due to male factor, not the woman.
- Haver got one one-hour lecture on menopause in medical school and nothing on perimenopause.
- Panel argues the year-long wait to diagnose menopause needlessly makes women suffer while their bones, brain and heart starve of estrogen.
- Haver discovers her mother's calming 'mommy's little helper' (Butol) was a phenobarbital-derivative sedative prescribed heavily to women.
Things worth remembering
- Of $450 billion spent on US research, less than 1% goes to women over 40, who number nearly 90 million.
- Women live ~6 years longer than men but spend 20% more of their lives in poor health.
- Up to 50% of women with gestational diabetes develop type 2 diabetes within 10-15 years.
- The WHO estimates ~30% of women aged 15-49 are anemic, mostly from iron deficiency, rising to ~50% in parts of South Asia and sub-Saharan Africa.
- Pilot data suggests timed cold-water exposure (around 10C, not ice baths) can dampen inflammation and ease endometriosis symptoms.
- A female fetus has 6-7 million eggs at 5 months, dropping to 1-2 million at birth and ~400 ever ovulated in a lifetime.
- Monthly chance of pregnancy falls from ~20% at age 30 to ~5% at 38 and ~3% at 40.
- Men make ~1,500 sperm per second; sperm take ~72 days to make, so a single health change can shift sperm quality.
- One in four pregnancies ends in pregnancy loss; two in a row warrants evaluation.
- As of a 2023 US study, only ~4% of eligible women are filling FDA-approved menopause hormone therapy prescriptions.
