Africa and the Middle East
Over the 13 centuries of the
Arab slave trade in Africa, unknown numbers of Africans were enslaved and shipped to the Middle East.
"The Caliphate in Baghdad at the beginning of the 10th Century had 7,000 black eunuchs and 4,000 white eunuchs in his palace."
The Arab slave trade typically dealt in the sale of castrated male slaves. Black boys at the age of eight to twelve had their penises and scrota completely amputated. Reportedly, about two out of three boys died, but those who survived drew high prices.
Europe
Slavery
The employment or enslavement of eunuchs (castrated men) was practiced in classical and

China
According to legend, during the reign of the legendary Emperor Shun and Yu in China, in 2281 BC, castration was passed into law as a punishment, remaining so until the reign of
Gaozu of Tang (618–626 AD). However, it was still practiced after his reign. According to historians, it was incorporated into Chinese law during the Zhou dynasty. It was one of the five physical punishments that could be legally inflicted on criminals in China.

Chengtian took power at age 30 in 982 as a regent for her son. Some reports suggest that she personally led her own army against the Song Chinese in 986. Her army defeated them in battle, fighting the retreating Chinese army. She then ordered the castration of around 100 ethnic

Vietnam
The Vietnamese adopted the eunuch system and castration techniques from China. Records show that the Vietnamese performed castration in a painful procedure by removing the entire genitalia with both penis and testicles being cut off with a sharp knife or metal blade. The procedure was agonizing since the entire penis was cut off. The young man's thighs and abdomen would be tied, and others would pin him down on a table. The genitals would be washed with pepper water and then cut off. A tube would be then inserted into the urethra to allow urination during healing. Many Vietnamese eunuchs were products of self-castration in order to gain access to the palaces and power. In other cases, they might be paid to become eunuchs. They served in many capacities, from supervising public works, to investigating crimes, to reading public proclamations.

Early accounts recorded that the Vietnamese captured Chinese whose ships had blown off course and detained them. Young Chinese men were selected by the Vietnamese for castration to become eunuch slaves to the Vietnamese. It has been speculated by modern historians that the Chinese who were captured and castrated by the Vietnamese were involved in trade between China and Vietnam instead of actually being blown off course by the wind and they were punished as part of a crackdown on foreign trade by Vietnam.

The boy would have the option of serving as a eunuch official or serving the palace women when he became ten years old. This law was put in place in 1838 during the Nguyễn dynasty.

Prevention of crime
Chemical or surgical castration is practiced in many countries for people convicted of sex crimes as a prerequisite for their release from prison. The castration may be voluntary or mandated. The assumption is that it prevents future crimes. Reports are available from American and European countries for over 80 years (chemical for circa 30). The effectiveness and ethics of this treatment are heavily debated.

According to the reports compiled by Council of Europe, a human-rights forum, the central European country physically castrated at least 94 prisoners in the 10 years up to April 2008. The Czech Republic defends this procedure as voluntary and effective. According to Dr. Martin Hollý, director of the Psychiatric Hospital Bohnice in Prague, none of the nearly 100 sex offenders who had been physically castrated had committed further offences. One serial offender stated that being castrated was the "best decision" he ever made: "On the one hand you have to protect the potential victims and on the other hand I wanted to be protected from myself, I wanted to live like a normal person."

Previously, in several states, convicted offenders could choose castration, including where it was a prerequisite for parole.

Some criminologists argue that the reported lower recidivism rates in castrated male sex offenders compared to non-castrated ones does not conclusively prove that it is a biological effect of castration, but might be explained by other factors. One suggested factor from

is that men who are willing to accept castration to get a shorter prison sentence are those who value freedom from prison higher than men who are not willing to pay the price for freedom in the form of their testicles. This hypothesis could explain their apparent lower recidivism as a result of working harder to conceal the evidence for their crimes, and argue that their parole is a danger of releasing offenders who only hide their crimes more efficiently and are not any less likely to commit new crimes. These criminologists also argue that police investigators treating castrated men as less likely to reoffend than non-castrated men may cause an investigation bias and
self-fulfilling prophecy.

Isaiah 56:3–5 references in a positive welcoming manner eunuchs who follow after God's laws. "Neither let the son of the stranger, that hath joined himself to the LORD, speak, saying, The LORD hath utterly separated me from his people: neither let the eunuch say, Behold, I am a dry tree.

brought them into contact with eunuchs. By the eighth century, the palaces of the caliphs were staffed with many eunuch slaves which sold at a premium. A regular trade in eunuchs developed with slaves being taken to locations in Spain or Africa to be castrated, as the practice of castration was forbidden for Muslims. Eunuchs were used as harem supervisors, as mediators or servile roles, but they could also rise to be trusted advisors or military commanders.

Medical consequences
A subject of castration who is altered before the onset of puberty will retain a high voice, as well as the effects of hypogonadism, which include non-muscular build, an infantile penis, a lack of a beard, more developed subcutaneous fat. He may be taller than average, with long limbs, so called "eunuchoid appearance", as the production of sex hormones in puberty—more specifically, estrogen via aromatization of testosterone—stops long bone growth in a process called osseous maturation. The subject may lack the male distribution of axillary hair, and may develop pubic hair

Historically, many eunuchs who additionally underwent a penectomy reportedly had urinary incontinence associated with the removal of the penis.

Livestock may be castrated when used for food to prevent indiscriminate breeding, control aggression, and improve meat and carcass quality. In domestic pigs the undesirable odour or taint of uncastrated males, called boar taint, is caused by androstenone and skatole

concentrations stored in the fat tissues of the animal after sexual maturity.[Genetics of Boar Taint: Implications for the Future Use of Intact Males](_blank)
Boar taint is only found in a small minority of pigs and can be controlled through breeding selection, diet and management. It is released when the fat is heated and has a distinct odor and flavor that is widely considered unpalatable to consumers.
Consequently, in commercial meat production, male pigs are either castrated shortly after birth or slaughtered before they reach sexual maturity. Recent research in Brazil has shown that castration of pigs is unnecessary because most pigs do not have the 'boar taint'. This is due to many breeds of pigs simply not having the heredity for the boar taint and the fact that pigs are normally slaughtered at a young market weight.
In the case of pets, castration is usually called neutering
Neutering, from the Latin ('of neither sex'), is the removal of a non-human animal's sex organ, reproductive organ, either all of it or a considerably large part. The male-specific term is castration, while spaying is usually reserved for female ...
, and is encouraged to prevent overpopulation of the community by unwanted animals, and to reduce certain diseases such as prostate disease and testicular cancer in male dogs (oophorectomy in female pets is often called spaying). Testicular cancer is rare in dogs, and also prostate problems are somewhat common in castrated male dogs when they get older. Neutered individuals have a much higher risk of developing prostate problems in comparison to intact males. Castrated male cats are more likely to develop an obstruction in their urethra, preventing them from urinating to some degree. A specialized vocabulary has arisen for neutered animals of given species:

Castration of cattle has historically been done without pain medications. All methods of castration cause pain and distress, which can be minimized by castrating as early as possible, preferably within the first week of life.
