Biology and culture collide! We discuss the intersection of sex, gender, and sports with Dr. Adrianna San Roman, a postdoctoral fellow at the Whitehead Institute in Cambridge who studies sex chromosome aneuploidy. Adrianna first walks us through the biological basis of sex and explains why it is more complicated than just male and female. Definitions in place, we then talk about the cases of Dutee Chand and Caster Semenya, Olympic athletes who have been banned from competition due to elevated testosterone levels. You’ll be Sry if you miss this one!
