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 aims to prohibit the participation of males in athletic programs or activities specifically designated for women or girls at the United States military service academies. It mandates that the Secretary of Defense ensure the U.S. Military Academy, Naval Academy, and Air Force Academy do not permit individuals whose sex is male to join these designated programs. However, the legislation includes a rule of construction allowing males to train or practice with women's teams, provided no female is deprived of a roster spot, opportunity, scholarship, or other benefits. The bill explicitly defines "sex" as a person's reproductive biology and genetics at birth, establishing a clear basis for its provisions.
