Castration, gelding, neutering, orchiectomy, or orchidectomy is any action, surgical, chemical, or otherwise, by which a biological maleloses use of the testes. This causes sterilization, i.e. prevents 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 vasa deferentia, the tubes which connect the testicles to the prostate.

The term "castration" is sometimes also used to refer to the removal of the ovariesin the female, otherwise known as an oophorectomyor, in animals, spaying. This is similar to male castration, as it causes females to stop producing estrogen, and makes them infertile.

Castration in humans

History

The practice of castration has roots before recorded human history. Castration was frequently used in certain cultures, such as in Europe, the Middle East, India, Africaor China, for religious or social reasons. After battles, winners castrated their captives or bodies of the defeated to symbolise their victory and 'seize' their power. Castrated men - eunuchs- were often admitted to special social classes. Eunuchs were also often used to guard harems. Castration also figured in a number of religious cults: see castration cults. Other religions, for example Judaism, were strongly opposed to the practice. Indeed, eunchs in China have been known to usurp power in many parts of Chinese history, most notably in the Ming Dynasty.

African slave traders also frequently castrated their charges in order to increase their commercial value. After denying the victim fluids for a day or two, they would sever the penis and testicles, and use a hot iron to cauterisethe wound closed. They would then force the prospective slave to drink so that hopefully the pressure of the bladder would be able to force an opening in the wound for urine. It is estimated that 90% of the slaves so treated died in the attempt, however, castrated slaves were greatly valued and sought both in Europe and in the East, where Christians and Jews formally discouraged the practice but informally were happy to purchase already-castrated slaves from Muslim traders.

In Europe, when womenwere not permitted to singin church or cathedral choirs in the Roman Catholic Church, young boys were sometimes castrated to prevent their voices breaking at puberty and to develop a special high voice. These men, known as castratiwere very popular in the Eighteenth Century. The practice of employing castrati lasted longest in Italian churches, most notoriously in the Sistine ChapelChoir. [1][2]

Remains of transsexualand transgenderedpeople from as far back as the Roman erahave been uncovered and confirmed to have undergone castration.

Castration in humans has been proposed, and sometimes used, as a method of birth controlin certain poorer regions.

Reasons

Surgical removal of both testicles or chemical castrationmay be carried out in the case of prostate cancer, as hormonetestoterone depletion treatment to slow down the cancer, or as testosterone depletion treatment to greatly reduce sexual drive/interest in those with 'deviant'sexual drives/obsessions and/or behaviors.[3]

Male-to-female transsexuals, as well as some transgenderedpeople, often undergo castration. Castration can be done before, during, or in place of sex reassignment surgery.

A temporary chemical castration has been studied and developed as a preventive measure and punishmentfor several repeated sex crimessuch as rapeor other sexually related violence. Voluntary chemical or surgical castration has been in practice in many countries; reports are available from Scandinavian and European countries in particular, for the past eighty plus years (chemical for the last thirty or so years) as a an option for effective treatment of child molesters, rapists and sexual sadists, allowing them to return to the community from otherwise lengthy detentions. In the case of chemical castration, on-going regular injections of anti-androgensare required. Physical castration is highly effective as, historically, it results in a 20-year re-offense rate of less than 2.2%, much lower than what was otherwise expected. Unfortunately, chemical castration seems to be even harder on bone density than is physical castration. Since the developement of Forteo, this severe bone loss has been able to be reversed in nearly every case... At this time there is a limitation on the use of this medication to 24 months, until the long-term use is better evaluated. There is also evidence that voluntary castration is used in modern societies for reasons such as control of libido, body modification, and in some cases of extreme sexual masochism, for purposes of sexual excitement (see paraphiliaand apotemnophilia). With the advent of chemical castration, physical castration is not generally reccommended by the medical community. An underground network of castrators (generally called "cutters") without medical licenseshas formed. Surgery performed by untrained personnel outside a properly equipped medical facility is dangerous, and there have been cases of severe bleeding and other medical emergencies. Alternatively, self-castration(or autocastration) is occasionally performed, though it carries significant risk. Many who desire castration travel to developing countries, where medicine is less tightly regulated, and have the procedure performed by a doctor. Involuntary castration also appears in the history of warfare, sometimes used by one side to torture or demoralize their enemies. It was also practiced to extinguish opposing male lineages and thus allow the victor to possess the defeated men's women. Involuntary castration under such circumstances involved excruciating pain and humiliation as well as various physical, social, and psychological consequences. Ancient Greek writings report Persian forces castrating defeated foes. Tamerlanewas recorded to have castrated Armenianprisoners of war who had fought as allies of the Ottoman Sultan Bayezid I; others were buried alive. Gibbon's famous work, Decline and Fall of the Roman Empire reports castration of defeated foes at the hands of the Normans. The Vietconghave sometimes been accused of castrating US war prisoners, Vietnamesevillage elders, and others who opposed their policies. Castration has also been used in modern conflicts, as the Janjaweedmilitiamen currently (as of 2005) attacking citizens of the Darfurregion in Sudanoften castrate villagers and leave them to bleed to death as part of a campaign of terror [4].

Sima Qian, the famous Chinese Historian, was castrated by order of the Emperor of China for dissent. Another famous victim of castration was the medieval monk Abelard, castrated by his lover's relatives.

Yet another famous castration victim was Bishop Wimund, a 12th Century English adventurer and invader of the Scottish coast.

Several members of Marshall Applewhite's Heaven's Gate cultunderwent castration for religious reasons, including Applewhite himself.

Medical consequences

A subject of castration who is castrated before the onset of pubertywill retain his high voice, slight build and small genitals, will not develop pubic hair, and will have a small sex drive or none at all. This practice was used to maintain angel-like voices for choir boys in service of the church during the Middle Ages. In the baroque music era these singers were highly appreciated by the Opera composers as well. Famous castrati include: Farinelli, Senesino, Carestini and Caffarelli. The Last "castrato" was Alessandro Moreschi(1858-1922) who served in the Vatican church.

In ancient times, castration often involved the total removal of all the male genitalia. This involved great danger of death due to bleeding or infection, and in some states, such as the Byzantine Empire, was seen as the same as a death sentence. Removal of only the testicles had much less risk. That said, the Hijrasof India still practice the total removal of the male genitalia.

Castrations after the onset of puberty will typically reduce the sex drive considerably or eliminate it altogether. Castrates can, however, still have erections, orgasmsand ejaculations. The voice will normally not change. Some castrates report mood changes, such as depressionor a more serene outlook on life. Body strength and muscle mass can decrease somewhat. Body hair may or may not decrease. Castration prevents male pattern baldness[5].

In China, male castration of a person who entered the caste of eunuchs under imperial times involved the removal of all genitalia, that is, the removal of the penis, testicles and scrotum. The removed organs were returned to the eunuch, to be interred with him once he dies, so upon rebirth, he could become a whole man again. The penis, testicles and scrotum were euphemistically termed as bǎo (寶) in Mandarin Chinese, which literally means 'precious treasure'. These were supposedly deep fried and then dried in the wind, before placing into silk pouches. Eunuchs suffered from a range of urogenital problems associated with the removal of their sexual organs, and they had their own specialist doctors who catered to their health needs.

Castration In Veterinary Practice

Image:Castration horse.jpg Castration is common in animal husbandryand animal fancy, where it is intended for favouring a given desired development of the animal or of its habits. Spaying and neuteringof household pets is encouraged to prevent overpopulation of unwanted animals.

In animal fancy

Usually domestic petsare subject to castration in order to avoid sexual frustration or sexual contacts and consequent reproduction. In the case of pets, this is usually called neutering. Breedingspecimens are kept entireand fetch higher prices when sold.

In animal husbandry

In the foodindustry, cattleand other ruminantsare often castrated in order to increase their weight and improve the taste of the meat (with the advantage of relevant economies of scale for the breeder). Male animals may also be castrated in order to make them more tractable.

Certain animals, like horsesand swine, are usually treated with a scrotal castration (which can be done with the animal standing), while others, like dogsand cats, with a pre-scrotal castration (with the animal recumbent).

Methods of veterinarycastration include surgicalremoval, the use of an elastratortool to secure a band around the testicles that disrupts the blood supply, the use of a Burdizzotool or emasculators to crush the spermatic cordsand disrupt the blood supply, pharmacologicalinjectionsand implantsand immunologicaltechniques to inoculatethe animal against its own sexual hormones.

In veterinary practice an "open" castration refers to a castration in which the inguinal tunic is incised and not sutured. A "closed" castration refers to when the procedure is performed so that the inguinal tunic is sutured together after incision.
