castration

[kastrā′shən]
Etymology: L, castrare, to castrate
the surgical excision of one or both testicles or ovaries, performed most frequently to reduce the production and secretion of certain hormones that may stimulate the proliferation of malignant cells in women with breast cancer or in men with prostate cancer. The patient must be informed that bilateral excision of the gonads causes sterility. See also oophorectomy, orchidectomy.

castration

The removal of gonads; castration occurs in various contexts:
1. Forensic–a controversial procedure intended to ↓ sexual drives in repeat sex offenders.
2. Pathologic–due to infection, which renders both testes functionally inactive–eg, with filariasis in elephantiasis.
3. Therapeutic–to remove the source of androgens in Pts with androgen-sensitive prostate CA–which can also be accomplished by RT. See Chemical castration, Medical castration, Surgical castration Psychiatry The fantasized loss of the genitals; a mental state of impotence, powerlessness, helplessness, or defeat Urology Surgical removal of testes in ♂ with androgen-dependent prostate CA.

Burdizzo castration
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
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.
