The purpose of this legislation, known as the Truth in Gender Act of 2025, is to affirm and protect women's rights by establishing clear definitions of biological sex and ensuring that federal policies and practices reflect these definitions. The act aims to counter what it describes as "gender ideology," which it claims undermines the biological distinctions between men and women. Key provisions of the act include the establishment of definitions for sex, women, men, and related terms, emphasizing that these are based on biological characteristics rather than gender identity.
