Castration (also referred as: gelding, neutering, orchiectomy, and orchidectomy) is any action, surgical, chemical, or otherwise, by which a biological male loses use of the testes. This causes sterilization, preventing him from reproducing; it also greatly reduces the production of certain hormones, such as testosterone. It is usually considered painful, and in some countries is used as torture. It should not be confused with penectomy, which is the whole or partial removal of the penis, nor with vasectomy, which is a procedure to sterilize a male by blocking the vas deferens, the tubes that connect the testicles to the prostate.
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. This is similar to male castration, as it causes females to stop producing estrogen, and makes them infertile.
