Protection of Women and Girls in Sports Act of 2025
Received in the Senate.
This bill amends Title IX to require that for athletics, a person’s sex is determined solely by reproductive biology and genetics at birth. It prohibits recipients of federal funds from allowing persons whose sex is male at birth to participate in teams or athletic activities designated for women or girls.
Progressives emphasize discrimination and harms to transgender youth
Relative to its intended legislative type, this bill clearly accomplishes a narrowly defined substantive amendment to Title IX athletics provisions and adds a required federal study.

It is precise in establishing the legal rule and in locating the amendment within the existing statutory framework, but it omits practical implementation details, fiscal acknowledgement, timelines, and comprehensive treatment of foreseeable edge cases.

Why the argument around this bill splits.
Progressives emphasize discrimination and harms to transgender youth
Likely to view the bill as discriminatory toward transgender girls and women because it uses birth-assigned sex only.
Supporters of inclusion will argue it overrides identity-based policies and may violate civil rights protections.
They will emphasize harms to transgender youth and potential legal conflicts with existing nondiscrimination interpretations.
Views the bill as addressing legitimate concerns about fairness in women's sports but too blunt to account for medical, legal, and practical complexity.
Interested in clear standards and evidence, while worried about legal exposure and implementation burdens on schools.
Likely to strongly support the bill as a necessary protection of female athletic opportunities.
Sees a clear birth-sex standard as the fairest, most objective approach that prevents males from occupying girls' roster spots and scholarships.
