(Note: This program originally aired back in October.) On this edition of ST Medical Monday, our guest is Randi Hutter Epstein, M.D., M.P.H., who is an adjunct professor at Columbia and a lecturer at Yale. She joins us to discuss her book, "Aroused: The History of Hormones and How They Control Just About Everything." Per Publishers Weekly: "Science writer Epstein gives readers a lucid and entertaining look at the social and scientific history of endocrinology. Epstein roots her history in people, such as 19th-century 'rooster-testicle-swapping' German researcher, Arnold Berthold (1803–1861), who showed that glands released hormones into the blood rather than into the nervous system, and Park Avenue doctor Louis Berman (1893–1946) who, when he wasn't treating celebrities, wrote popular books offering hormone remedies and predicting that once Western medicine learned how to exploit the endocrine system, Earth would be full of superhumans.... The author's beguiling prose...makes for a lively and accessible introduction to hormones and the important work they do in the lives of humans."
