HB 1053 Missouri House · 2025 Regular Session

Modifies provisions relating to the biological definition of male and female

HB 1053 defines key biological terms in state law, specifying that "female" refers to individuals with an egg-producing reproductive system (accounting for anomalies) and "male" refers to those with a sperm-producing system. It requires that "gender," when used alone in existing laws, must mean biological sex - not gender identity or expression - and explicitly prohibits using "gender" as a synonym for "sex." The bill also ensures individuals with disorders of sex development retain protections under the Americans with Disabilities Act. This directly affects legal documents, policies, and administrative rules that reference sex or gender classifications.
