Castration
Castration is any action, surgical, chemical, or otherwise, by which an individual loses use of the testicles: the male gonad. Surgical castration is bilateral orchiectomy (excision of both testicles), while chemical castration uses pharmaceutical drugs to deactivate the testes. Castration causes sterilization (preventing the castrated person or animal from reproducing); it also greatly reduces the production of hormones, such as testosterone and estrogen. Surgical castration in animals is often called neutering. The term ''castration'' is sometimes also used to refer to the removal of the ovaries in the female, otherwise known as an oophorectomy, or the removal of internal testes, otherwise known as gonadectomy. The equivalent of castration for female animals is spaying. Estrogen levels drop following oophorectomy, and long-term effects of the reduction of sex hormones are significant throughout the body. Castration of animals is intended to favor a desired develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Castration
Chemical castration is castration via anaphrodisiac drugs, whether to reduce libido and sexual activity, to treat cancer, or otherwise. Unlike surgical castration, where the gonads are removed through an incision in the body,"Can Castration Be a Solution for Sex Offenders? Man Who Mutilated Himself in Jail Thinks So, but Debate on Its Effectiveness Continues in Va., Elsewhere" by Candace Rondeaux for the Washington Post, July 5, 2006 chemical castration does not remove organs, nor is it a form of sterilization. ...

Eunuch
A eunuch ( ) is a male who has been castrated. Throughout history, castration often served a specific social function. The earliest records for intentional castration to produce eunuchs are from the Sumerian city of Lagash in the 2nd millennium BCE. Over the millennia since, they have performed a wide variety of functions in many different cultures: courtiers or equivalent domestics, for espionage or clandestine operations, castrato singers, concubines, or sexual partners, religious specialists, soldiers, royal guards, government officials, and guardians of women or harem servants. Eunuchs would usually be servants or slaves who had been castrated to make them less threatening servants of a royal court where physical access to the ruler could wield great influence. Seemingly lowly domestic functions—such as making the ruler's bed, bathing him, cutting his hair, carrying him in his litter, or even relaying messages—could, in theory, give a eunuch "the ruler's ear" a ...

Spaying
Neutering, from the Latin ''neuter'' ('of neither sex'), is the removal of an animal's reproductive organ, either all of it or a considerably large part. The male-specific term is castration, while spaying is usually reserved for female animals. Colloquially, both terms are often referred to as fixing. In male horses, castrating is referred to as '' gelding''. An animal that has not been neutered is sometimes referred to as '' entire'' or ''intact''. Neutering is the most common method for animal sterilization. Humane societies, animal shelters, and rescue groups urge pet owners to have their pets neutered to prevent the births of unwanted litters, which contribute to the overpopulation of unwanted animals in the rescue system. Many countries require that all adopted cats and dogs be sterilized before going to their new homes. Methods of sterilization Females (spaying) Spaying is the surgical removal of the ovaries and uterus in female animals. It is commonly performed a ...

Oophorectomy
Oophorectomy (; from Greek , , 'egg-bearing' and , , 'a cutting out of'), historically also called ''ovariotomy'' is the surgical removal of an ovary or ovaries. The surgery is also called ovariectomy, but this term is mostly used in reference to animals, e.g. the surgical removal of ovaries from laboratory animals. Removal of the ovaries of females is the biological equivalent of castration of males; the term ''castration'' is only occasionally used in the medical literature to refer to oophorectomy of women. In veterinary medicine, the removal of ovaries and uterus is called ovariohysterectomy (spaying) and is a form of sterilization. The first reported successful human oophorectomy was carried out by (Sir) Sydney Jones at Sydney Infirmary, Australia, in 1870. Partial oophorectomy or ovariotomy is a term sometimes used to describe a variety of surgeries such as ovarian cyst removal, or resection of parts of the ovaries. This kind of surgery is fertility-preserving, althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emasculation
Emasculation is the removal of both the penis and the testicles, the external male sex organs. It differs from castration, which is the removal of the testicles only, although the terms are sometimes used interchangeably. The potential medical consequences of emasculation are more extensive than those associated with castration, as the removal of the penis gives rise to a unique series of complications. There are a range of religious, cultural, punitive, and personal reasons why someone may choose to emasculate themselves or another person. Consensual emasculation may be seen as a form of body modification that enhances a recipient's identification with their community or sense of self. By comparison, non-consensual emasculations, such as those performed punitively or accidentally, may constitute genital mutilation. The medical treatment for an emasculated person differs depending on whether the procedure was consensual. The term ''emasculation'' may be used metaphorically to ...

Orchiectomy
Orchiectomy (also named orchidectomy, and sometimes shortened as orchi or orchie) is a surgical procedure in which one or both testicles are removed. The surgery is performed as treatment for testicular cancer, as part of surgery for transgender women, as management for advanced prostate cancer, and to remove damaged testes after testicular torsion. Less frequently, orchiectomy may be performed following a trauma, or due to wasting away of the testis or testes. Procedure Simple orchiectomy A simple orchiectomy is commonly performed as part of gender reassignment surgery for transgender women, or as palliative treatment for advanced cases of prostate cancer. A simple orchiectomy may also be required in the event of testicular torsion. For the procedure, the person lies flat on an operating table with the penis taped against the abdomen. The nurse shaves a small area for the incision. After anesthetic has been administered, the surgeon makes an incision in the midpoint of the s ...

Harem
Harem ( Persian: حرمسرا ''haramsarā'', ar, حَرِيمٌ ''ḥarīm'', "a sacred inviolable place; harem; female members of the family") refers to domestic spaces that are reserved for the women of the house in a Muslim family. A harem may house a man's wife or wives, their pre-pubescent male children, unmarried daughters, female domestic servants, and other unmarried female relatives. In harems of the past, slave concubines were also housed in the harem. In former times some harems were guarded by eunuchs who were allowed inside. The structure of the harem and the extent of monogamy or polygamy has varied depending on the family's personalities, socio-economic status, and local customs. Similar institutions have been common in other Mediterranean and Middle Eastern civilizations, especially among royal and upper-class families, and the term is sometimes used in other contexts. In traditional Persian residential architecture the women's quarters were known as ''andar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testicles
A testicle or testis (plural testes) is the male reproductive gland or gonad in all bilaterians, including humans. It is homologous to the female ovary. The functions of the testes are to produce both sperm and androgens, primarily testosterone. Testosterone release is controlled by the anterior pituitary luteinizing hormone, whereas sperm production is controlled both by the anterior pituitary follicle-stimulating hormone and gonadal testosterone. Structure Appearance Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's anatomy. For 85% of men, the right testis hangs lower than the left one. Measurement and volume The volume of the testicle can be estimated by palpating it and comparing it to ellipsoids of known sizes. Another method is to use calipers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testosterone
Testosterone is the primary sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone in both sexes is involved in health and well-being, including moods, behaviour, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss. Testosterone is a steroid from the androstane class containing a ketone and a hydroxyl group at positions three and seventeen respectively. It is biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites. It exerts its action through binding to and activation of the androgen receptor. In humans and most other vertebrates, testosterone is secreted primarily by the testicles of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anaphrodisiac
An anaphrodisiac (also antaphrodisiac or antiaphrodisiac) is a substance that quells or blunts the libido. It is the opposite of an aphrodisiac, something that enhances sexual appetite. The word ''anaphrodisiac'' comes from the Greek privative prefix ἀν-, denoting negation, and ''aphrodisiac'', from the Greek goddess of love, Aphrodite. Some people use anaphrodisiacs in order to curb a very high libido or due to hypersexuality. However anaphrodisiacs are also used by those with an average libido, at times due to having incessant schedules. Available anaphrodisiacs classes of substances Some common anaphrodisiacs are ethanol (alcohol) and tobacco, but this is typically an unintended consequence and not often the main reason for use. While alcohol is used socially because it initially reduces mental inhibitions, studies have shown that over time alcohol physically decreases arousal and makes achieving climax more difficult. For this reason alcohol is considered an anaphrodisiac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgery
Surgery ''cheirourgikē'' (composed of χείρ, "hand", and ἔργον, "work"), via la, chirurgiae, meaning "hand work". is a medical specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas. The act of performing surgery may be called a surgical procedure, operation, or simply "surgery". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments or surgical nurse. The person or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and a surgeon's assistant is a person who practices surgical assistance. A surgical team is made up of the surgeon, the surgeon's assistant, an anaesthetist, a circulating nurse and a surgical technologist. Surgery usually ...
