Testosterone and sport

We look at the science behind the debate.

In early December 2021 a member of Penn University Women’s Swim Team caused a stir. Lia Thomas not only won three events but she had the fastest time in elite college swimming in the country in two out of three races. This achievement reignited a debate as Lia Thomas is a transgender woman; we examine the rules around testosterone and trans women’s participation in elite sport.
