Episode 4: In 2009, South African sprinter Caster Semenya won gold at the World Championships. But instead of a celebration, she endured endless speculation about her body, her biology, and her gender. And soon, sports organizations would launch a new round of regulations, lead to multiple court cases, and require sporting organizations to justify their claim that DSD athletes have an unfair advantage.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Episode 3: We meet Kenyan sprinter Maximila Imali, who—like Christine Mboma—has been sidelined by DSD policies. She makes a different choice from Christine: to fight the regulations in court.

Episode 2: We go back almost 100 years, to the beginning of women's inclusion in elite sports. It turns out that men had an odd variety of concerns about women athletes.

Episode 1: Would you alter your body for the chance to compete for a gold medal? That's the question facing a small group of elite athletes right now. Last year, track and field authorities announced new regulations that mean some women can't compete in the female category unless they lower their body's naturally occurring testosterone levels. You'll meet one of those runners, Christine Mboma, a reigning Olympic silver medalist, and hear about the difficult choice she faces.

Who gets to compete? Since the beginning of women's sports, there has been a struggle over who qualifies for the women's category. Tested follows the unfolding story of elite female runners who have been told they can no longer race as women, because of their biology. As the Olympics approach, they face hard choices: take drugs to lower their natural testosterone levels, give up their sport entirely, or fight. To understand how we got here, we trace the surprising, 100-year history of sex testing. Tested is a new 6-part series from NPR's Embedded and CBC. Hosted by journalist Rose Eveleth, it launches July 15, ahead of the 2024 Olympic Games.
