In 2022, the Canadian Centre for Ethics in Sport (now called Sport Integrity Canada) published "Transgender Women Athletes and Elite Sport: A Scientific Review," an in-depth review of scientific literature on transgender athlete participation in competitive sport. Today, it was discovered that this report has been removed or blocked from their site; all materials are under the " Resources " section of this site. The CCES report reviewed published literature from 2011 to 2021

Sport has always claimed to be about fairness.... But when you look closely at the history of sex testing in women’s sports, a different pattern emerges: one rooted not in fairness, but in fear, control, and a persistent discomfort with women who don’t fit narrow expectations of what a female athlete “should” look like. Today, as governing bodies move back toward sex verification policies, it’s critical to understand this history, not as a relic of the past, but as a warning

“Fairness in sports” is one of the most common phrases used in public debate. It’s often framed as a core value - something that must be protected at all costs. But here’s the reality we rarely acknowledge: Sports have never been fair. They never have been, and they were never designed to be.

Although framed around elite or Olympic sport, these policies often apply to youth, club, r

The U.S. Supreme Court will hear oral arguments in the case of B.P.J. v. West Virginia , a case that could significantly reshape how transgender athletes are treated under federal law. While the case focuses on one transgender girl’s right to play school sports in West Virginia, its outcome could affect Title IX protections , transgender athlete participation , and the future of fairness in youth sports  nationwide. Understanding what’s at stake is critical not just for trans

The conversation around women’s sports and transgender athletes is often framed as a zero-sum debate: that in order to protect women’s sports, someone else must be excluded. This assumption is widespread - and deeply misleading. The reality is far more straightforward. The best way to elevate all  women in sports isn’t by restricting who can participate or policing people’s bodies and expression. It’s by creating inclusive environments where more people feel safe, supported,

Transgender Athlete Statistics and the Reality of High School Trans Athletes One of the most common myths about transgender athletes is the belief that large numbers of trans kids are playing sports everywhere  -  in every city, every school, and every level of competition. This myth shows up repeatedly in media coverage and political debates, especially when people talk about high school transgender athletes . But when we look at the actual data, a very different picture eme
