HB 156 Missouri House · 2025 Regular Session

Modifies provisions relating to the biological definition of male and female

HB 156 redefines key terms like "female," "male," and "gender" in state law to explicitly reference biological sex based on reproductive anatomy, rather than gender identity. It specifies that "gender" in state law must mean biological sex (not gender identity, expression, or role), and defines "female" and "male" as individuals with naturally developing reproductive systems for egg or sperm production. This bill directly affects all state agencies, laws, and administrative rules that use these terms, requiring them to align with the new biological definitions. The change aims to standardize terminology across state policy without creating new programs or altering existing rights.
