Burdizzo castration

see burdizzo emasculatome.

closed castration

see covered castration (below).

covered castration

the covering of the scrotal sac is incised and the testicle released still enclosed in its tunica vaginalis. The cord is ligatured and the testicle and its enveloping tunic removed in toto. Preferred for adult stallions or when the inguinal canal is considered to be sufficiently enlarged to permit eventration. Called also closed castration.

elastrator castration

see elastrator.

female castration

removal of the ovaries, or bilateral oophorectomy; spaying.

male castration

removal of the testes, or bilateral orchiectomy.

mutilatory castration

castration of companion animal males is thought by some to be an unnecessary mutilation. The view applies particularly to dogs. In the conflict between the animal liberators and those concerned with restraining the growth of the cat and dog populations, the zero population growth advocates hold most of the cards.

open castration

incision through the tunica vaginalis. Compare with covered castration (above).

prepubertal castration

in sheep, castration of males before puberty may result in a greater risk of subsequent obstructive urolithiasis because of failure of the urethra to fully develop its potential for dilatation.

castration-responsive dermatosis

some dogs with hyposomatotropism or growth hormone-responsive dermatosis will regrow hair after castration. The etiology is unclear.

standing castration

one done under sedation with local anesthetic with the animal standing. Most commonly done in horses.
