The International Olympic Committee has barred transgender athletes from competing in the women’s category of the Olympics and said that all participants in those events must undergo genetic testing.
The decision, the most consequential since Kirsty Coventry was elected last year as the first woman to serve as president of the I.O.C., followed a board meeting and months of speculation over the organization’s policy on one of the most contentious issues facing global sports. The rules will be applicable starting at the next Olympics, in Los Angeles in 2028.
