International Olympic Committee (IOC) announced a sweeping policy overhaul in July 2024, banning transgender women and athletes with differences in sex development (DSD) who underwent male puberty from competing in women's events at all IOC-sanctioned competitions starting at the 2028 Los Angeles Games. The decision mandates a one-time SRY gene screening to determine eligibility, marking a stark reversal from its 2021 stance that left criteria to individual sports. This shift follows high-profile controversies, including the Tokyo 2021 inclusion of transgender weightlifter Laurel Hubbard and the Paris 2024 women's boxing scandal involving Imane Khelif and Lin Yu-ting, who faced disqualification for sex eligibility issues before winning golds.
