This week we’re looking at the contentious medical and ethical history of circumcision. We're joined by Sarah B. Rodriguez, medical historian and lecturer in global health and bioethics at Northwestern University, to talk about about her book “Female Circumcision and Clitoridectomy in the United States: A History of a Medical Treatment." And we'll discuss the medical and ethical implications of infant male circumcision with Brian Earp, University of Oxford Research Fellow in Science and Ethics.
