Chemical castration is a medical procedure to reduce libido or treat cancer. Unlike surgical castration, chemical castration does not remove the sexual organs as it uses anaphrodisiac drugs. It is often considered as reversible when the drugs are discontinued. Some of the side effects reported among men include increase in body fat, decreased bone density, and larger mammary glands. Those reported by women include deflated breast glands, decreased bone density and muscle mass, lips discoloration, and reduced body hair. Chemical castration was first used in 1944 as a treatment for sex offenders. In the United States, certain states such as Iowa, Florida, and California, still sanction and utilize chemical castration as one of the possible sentences for sex offenders.
