The science, culture, and history of periods

Half the world has a menstrual cycle, and yet it’s still greatly misunderstood. Kate Clancy, professor of anthropology at the University of Illinois, Urbana-Champaign, joins host Krys Boyd to discuss the science of periods, reproductive health, and the ways we hide this simple fact of nature from daily life. Her book is “Period: The Real Story of Menstruation.”
