Overview
This bill establishes biological definitions of male and female in law, directly addressing how gender is defined and recognized in state statute.

What this changes
Creates a new law or program
Law today: The bill does not spell out the prior law. Federal statute does not currently contain a single uniform definition of biological sex that applies across all federal laws and programs.
If passed: This bill would establish federal definitions of 'male' and 'female' based on biological characteristics, likely affecting which facilities, programs, and policies apply to individuals in federal law. For Christian families, this could impact school policies, sports eligibility, bathroom access, and other regulations that distinguish between males and females.

Likely supporters & opponents
Likely support
- Religious-liberty and religious-conservative organizations — Defining sex biologically aligns with biblical teaching on creation and protects religious parents' ability to raise children with traditional views of male and female.
- Parental-rights advocates — Clear biological definitions support parental authority to guide children's understanding of sex and prevent schools from adopting competing gender ideologies without parental input.
Likely opposition
- Civil-liberties and LGBTQ-advocacy organizations — A uniform biological definition excludes transgender and intersex individuals from legal recognition and restricts their access to facilities and programs consistent with their identity.
- Medical and psychological associations — Medical consensus recognizes that sex and gender are complex; a narrow biological definition contradicts professional standards for care of transgender patients.

Should I support this?
Likely helpful for Christian families
For Christian parents who teach that sex is a fixed biological reality rooted in God's design, this bill protects the legal recognition of that distinction and reduces pressure on schools and programs to adopt gender-identity frameworks that conflict with those beliefs. It affirms parental authority over their children's understanding of sexuality and biology.
