Castration is any action, surgical, chemical, or otherwise, by which a male loses use of the testicles: the male gonad. Surgical castration is bilateral orchiectomy, while chemical castration uses pharmaceutical drugs to deactivate the testes. Castration causes sterilization ; it also greatly reduces the production of hormones, such as testosterone and estrogen. Surgical castration in animals is often called neutering.
