Summary

Prohibits recipients of federal financial assistance that run or support athletic programs from allowing any person whose sex is male to participate in athletic programs or activities designated for women or girls. It defines “sex” for this rule as the sex assigned at birth based solely on reproductive biology and genetics, allows limited practice/training by males only when no female loses roster spots or other opportunities, and directs the Comptroller General to study and report on harms to girls from allowing males in girls’ sports.
