Guest: Randi Hutter Epstein

We blame a lot on our hormones – weight gain, sex drive, sleep loss, mood swings, illness and more. And justly so, as science writer RANDI HUTTER EPSTEIN details in her new book, Aroused: The History of Hormones and How They Control Just About Everything. This hour, Epstein walks us through the fascinating history of endocrinology, the early and sometimes bizarre experiments around chemicals like leptin, oxytocin, estrogen, and testosterone, the medical advances that changed the lives of countless patients, and the missteps along the way.
