The act of removing the testicles.
Any act that removes power from a person (particularly a man) or entity.
Castration is any action, surgical, chemical or otherwise, by which a biological male loses use of the testes. This causes sterilization, i.e. prevents them from reproducing; it also greatly reduces the production of certain hormones, such as testosterone. The term "castration" is sometimes also used to refer to the removal of the ovaries in the female, otherwise known as an oophorectomy or, in animals, spaying. The estrogen that the females produce becomes obsolete with this surgical procedure. The procedure may be purposely performed on humans variously as a punishment, or to decrease the libido of sex offenders. In animals, castration is intended for favouring a given desired development of the animal or of its habits, or preventing overpopulation.
