USA - For the first time in Olympic history, men who identify as "women" are being allowed to compete against women during the Winter Games in South Korea. “For the first time, the IOC [International Olympic Committee] has ruled that transgender athletes can take part in the Olympics. Female-to-male athletes can compete “without restriction,” while male-to-female athletes must undergo hormone therapy. Previously, IOC guidelines called for athletes to have reassignment surgery followed by at least two years of hormone therapy in order to be eligible. The only remaining regulation is that male-to-female athletes must demonstrate that their testosterone levels have consistently been below the cutoff point for at least one full year prior to competition.
