Episode notes
WHI Used Non-Human Hormones
- The Women's Health Initiative used non-human conjugated equine estrogens and a synthetic progestin, creating results that do not generalize to bioidentical hormones.
- Felice Gersh argues the study produced widespread misinformation and fear about all hormone therapy.
Estrogen Is Not One Thing
- Estrogen is a family of different molecules (estradiol, estrone, estriol) that bind different receptors and have distinct effects.
- Treating all 'estrogen' as one ignores receptor specificity and physiology, leading to poor conclusions.
Differentiate Synthetic From Bioidentical
- Do not conflate synthetic conjugated equine estrogens and progestins with human bioidentical hormones when discussing safety.
- Use physiologic, bioidentical estradiol and progesterone when clinically appropriate rather than labeling all hormones 'unsafe'.
