Officially: Defining Male and Female Act of 2025
HR 2378 would lock in biological definitions for male, female, and sex across every federal law and agency rule. Gender identity could not be used as a substitute for sex in any federal context. The change could reshape how civil rights protections, government records, and public programs handle sex-based categories.
