West Virginia v. B. P. J. · ¶105

In any event, the plaintiffs’ premise is the subject of ongoing medical and scientific debate and is not settled in their direction at this time. States and leading athletic organizations disagree with the plaintiffs and have concluded that biological males still retain a physical advantage after taking puberty blockers and hormones. To take one prominent example, the IOC found that “athletes retain Male performance advantage due in part to training effects and fixed traits. There is no current evidence that testosterone suppression or gender-affirming hormone treatment eliminates this advantage.” IOC, Policy on the Protection of the Female (Women’s) Category in Olympic Sport and Guiding Considerations for International Federations and Sports Governing Bodies (Mar. 26, 2026).
