A bill 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 males from participating in athletic programs or activities at the U.S. Military Academy, Naval Academy, and Air Force Academy that are designated for women or girls. It requires the Secretary of Defense to ensure these academies do not allow male participants in such women-focused teams. However, males may train or practice with these teams if no female loses a roster spot, competition opportunity, scholarship, or other benefit. The bill defines "sex" as a person's reproductive biology and genetics at birth, and "athletic programs" as any team-based activity with conditional participation. The law directly affects athletic team composition at these three military service academies.
