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, Host Rose Eveleth (they/them) traces the surprising, 100-year history of sex testing.

  1. Episode 1: The Choice

    EPISODE 1

    Episode 1: The Choice

    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 athletes can’t compete in the female category unless they lower their body’s naturally occurring testosterone levels. In this episode you’ll meet one of those runners, Christine Mboma, a reigning Olympic silver medalist, and hear about the difficult choice she faces.

    Episode 2: Questions of a Physical Nature

    We go back to the beginnings of women’s inclusion in elite sports. It turns out that men had an odd variety of concerns about women athletes. Some doubted these athletes were even women at all. And that skepticism resulted in the first sex testing policies. For early access to Tested episodes and to listen ad-free, subscribe to CBC's Stories channel here.

    Episode 3: Card-Carrying Females

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

    Episode 4: Running In Circles

    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.  For early access to Tested episodes and to listen ad-free, subscribe to CBC's Stories channel here.

  • If laughter really was the best medicine, Gavin Crawford would have cured his mother of Alzheimer’s disease. As a son, his mother’s dementia has been devastating. As a comedian though… it’s been sort of funny. Honestly, how do you respond when your mom confuses you with her teenage crush and wants you to take her to the high-school dance? Well, you laugh. Because it’s the only thing you can do. In this seven-part series, Gavin tells the story of losing his mother — his best friend and the inspiration for a lot of his comedy — to a disease that can be heartbreaking, but sometimes also hilarious. He’s joined by comedian friends who share their experience caring for family members with dementia. The result is a cross between an improv act and a support group.
