This spring, the Court of Arbitration for Sport upheld rules imposed by the International Association of Athletic Federations (IAAF) limiting the participation of female athletes with high levels of testosterone. On the other side of the decision was Caster Semenya: a South African runner who has repeatedly been penalized by sports officials throughout her career. The IAAF has gone through many iterations of their female regulations throughout the past decade, and Caster Semenya has been targeted with each successive policy. Most recently, the regulation has been a testosterone limit of five nanomoles per liter.

Throughout the past decade, the media has been following Semenya's story closely and shaping a narrative that is often misguided or inaccurate. In this video we piece together the underlying issues relevant to sex testing in sports and contextualize them within the long history of scrutinizing female athletes. By covering the controversy surrounding 2016 women’s 800 meters Olympic gold medalist Caster Semenya, along with historical events concerning Polish sprinter Ewa Klobukowska and Indian sprinter Dutee Chand, the goal is to help explain how athletic officials have repeatedly failed in their attempt to establish definitive sex testing regulations for female competitors.

So Kawhi is a woman now?

the strongest woman in the world is no where near as strong as the strongest man in the world, transgender females have an inherent unfair advantage and that is just a fact, no one is talking about transgender males because they don't possess the same hormonal advantage, if you honestly think that it is fair to women to allow transgender women to shatter athletic records then that is on you

testing would only commence for those who look suspicious (basically those who look manly)??? That is neither science or fair.

Lady Boys get ready to compete in the women sports
After listening to "her" and looking at the "adam's apple" it's pretty clear there's something funny going on...

lol notice how the athletes affected are black, the IAAF is racially discriminating these athletes because the europeans are not winning anymore because they’re not as fast as these black athletes. if you’re going to praise a white man on his genetic differences allowing him to excel at his sport why wouldn’t you do the same for black women? all people seem to do is praise white people for stuff but scrutinise black people for the same thing.
You so right. 🚀

Thanks for preparing this. Informative and is supportive of athletes.

Easy solution, create a non-binary category so trans and intersex people can continue to compete.
