To prohibit the participation of males in athletic programs or activities at the military service academies that are designated for women or girls.

This bill prohibits male students from participating in athletic programs at the U.S. Military Academies (West Point, Annapolis, and Air Force Academy) designated exclusively for women or girls. It allows males to train with such teams only if no female athlete loses a roster spot, competition opportunity, scholarship, or other benefit. The bill defines "sex" as biological sex at birth and clarifies that "athletic programs" include all team-based activities requiring participation. It directly affects the women's sports teams at these three service academies and their eligibility rules.
