How to Safeguard Your Hormone Health & Fertility | Dr. Shanna Swan

About this video

Huberman hosts Dr. Shanna Swan, a professor of environmental medicine and public health, who studies how environmental exposures affect reproductive health. Dr. Swan argues that compounds in air, food, water, cosmetics, and household items can act as endocrine disruptors, affecting testosterone, estrogen, and related brain and body pathways in fetuses, children, and adults. She discusses research linking such exposures to declining fertility, falling testosterone and sperm counts, and rising polycystic ovarian syndrome, as Huberman frames the episode. In the slices, Dr. Swan also describes studies measuring pesticide metabolites in urine and recounts Tyrone Hayes’s work on atrazine exposure and sexual development and behavior in frogs. Throughout, Dr. Swan emphasizes practical agency, describing everyday steps to do and to avoid in order to limit exposure, rather than presenting reproductive trends as unchangeable.
