Male castration is a procedure that involves removing the testes, thereby resulting in sterility, reduced sexual desire, and a lessening of testosterone production, which hampers hair growth and deepening of voice, explains eHow. Some men undergo castration as a means of cancer prevention or in an attempt to punish or prevent sex violations.
Chemical castration involves inactivation of the testes through pharmaceutical medication, whereas surgical castration entails the bilateral removal of both testes, according to Wikipedia. While under anesthesia, men undergoing surgical castration receive a minute incision in the scrotum in order to remove the testes, states the Med Network for Health. Following castration, prosthetic testes are occasionally used as a replacement.
While sexual desire is eliminated for many men after castration, some men experience little to no impact on their sex drive, thus adding to the controversy surrounding using this method of controlling sex offenders, notes the Medindia. Other effects include an increased likelihood of depression and suicidal tendencies, a reduction of calcium in the bones, a loss of proteins in the body, and less hemoglobin in the blood. Alterations in a man's physical appearance can also occur, including a softening of the skin, a loss of body hair, and additional body weight.
Castration that takes place before puberty causes a male to develop a non-muscular build, retain small genitals, and continue through life with a higher pitched voice, as noted on Wikipedia. It can also affect a boy's height, as the lack of testosterone prevents long bone growth.
