Carole Hooven is an evolutionary biologist at Harvard University and author of T: The Story of Testosterone, the Hormone that Dominates and Divides Us (2021). In this episode of Transparency, Carole was invited to ask Aaron K, Aaron T and Mars F questions about the changes they experienced upon initiating testosterone injections. Carole's research on the subject of testosterone and its impact on behaviour is both fascinating and highly informative.
