Male testosterone, with Melissa Fales. April 2014

This month, in our fifth anniversary episode (WUHOO!), I speak to Melissa Fales of UCLA about her new research on men’s hormone levels and how they vary over the course of their girlfriend’s menstrual cycle. We’ll also look at two other experiments on ovulation and attraction out this month: one on relationship conflict, and another on the sexual allure of musicians.
