The controversy surrounding gender testing in sports has resurfaced at the Paris Olympics, particularly impacting athletes like Algeria’s Imane Khelif and Taiwan’s Lin Yu-Ting. These boxers were previously disqualified from the 2023 World Championship by the International Boxing Association (IBA) for not meeting its opaque gender criteria, despite being allowed to compete in the Olympics under IOC guidelines that rely on gender identity and sex passports. This issue highlights the broader, contentious history and ethical concerns of sex testing in sports, as well as the problematic nature of using testosterone levels as a measure of eligibility. The case has sparked substantial debate and criticism from various quarters, including prominent figures and politicians, and underscores the long-standing struggle for fair and inclusive policies in women's sports.
