To prohibit the availability of Federal funds for certain animal research, and for other purposes.
Summary
This bill prohibits the use of federal funds to conduct, support, or fund animal research involving drugs, hormones, surgery, or other interventions designed to alter an animal's body to no longer correspond to its biological sex. The prohibition applies to non-human vertebrates including mammals, birds, fish, reptiles, and amphibians, but excludes animals that naturally change sex or possess both male and female reproductive organs during their lifetime. The restriction applies to both direct and indirect federal funding of such research.
