Castration in the context of "Overpopulation"

Aphrodite (/ˌæfrəˈdaɪtiː/ , AF-rə-DY-tee) is an ancient Greek goddess associated with love, lust, beauty, pleasure, passion, procreation, and as her syncretised Roman counterpart Venus, desire, sex, fertility, prosperity, and victory. Aphrodite's major symbols include seashells, myrtles, roses, doves, sparrows, and swans. The cult of Aphrodite was largely derived from that of the Phoenician goddess Astarte, a cognate of the East Semitic goddess Ishtar, whose cult was based on the Sumerian cult of Inanna. Aphrodite's main cult centers were Cythera, Cyprus, Corinth, and Athens. Her main festival was the Aphrodisia, which was celebrated annually in midsummer. In Laconia, Aphrodite was worshipped as a warrior goddess. She was also the patron goddess of prostitutes, an association which led early scholars to propose the concept of sacred prostitution in Greco-Roman culture, an idea which is now generally seen as erroneous.

A major goddess in the Greek pantheon, Aphrodite featured prominently in ancient Greek literature. According to many sources, like Homer's Iliad and Sappho's Ode to Aphrodite, she is the daughter of Zeus and Dione. In Hesiod's Theogony, however, Aphrodite is born off the coast of Cythera from the foam (ἀφρός, aphrós) produced by Uranus's genitals, which his son Cronus had severed and thrown into the sea. In his Symposium, Plato asserts that these two origins actually belong to separate entities; Aphrodite Urania (a transcendent "Heavenly" Aphrodite, who "partakes not of the female but only of the male", with Plato describing her as inspiring love between men, but having nothing to do with the love of women) and Aphrodite Pandemos (Aphrodite common to "all the people" who Plato described as "wanton", to contrast her with the virginal Aphrodite Urania, who did not engage in sexual acts at all. Pandemos inspired love between men and women, unlike her older counterpart). The epithet Aphrodite Areia (the "Warlike") reveals her contrasting nature in ancient Greek religion. Aphrodite had many other epithets, each emphasizing a different aspect of the same goddess or used by a different local cult. Thus she was also known as Cytherea (Lady of Cythera) and Cypris (Lady of Cyprus), because both locations claimed to be the place of her birth. Sappho's Ode to Aphrodite is one of the earliest poems dedicated to the goddess and survives from the Archaic period nearly complete.

A eunuch (/ˈjuː.nək/ YOO-nək, Ancient Greek: εὐνοῦχος) is a boy or man 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 BC. 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" and impart de facto power to the formally humble but trusted servant.

An ox (pl.: oxen), also known as a bullock (in British, Australian, and Indian English), is a large bovine, trained and used as a draft animal. Oxen are commonly castrated adult male cattle, because castration inhibits testosterone and aggression, which makes the males docile and safer to work with. Cows (intact females) or bulls (intact males) may also be used in some areas.

Oxen are used for ploughing, for transport (pulling carts, hauling wagons and even riding), for threshing grain by trampling, and for powering machines that grind grain or supply irrigation among other purposes. Oxen may be also used to skid logs in forests, particularly in low-impact, select-cut logging.

A bull is an intact (i.e., not castrated) adult male of the species Bos taurus (cattle). More muscular and aggressive than the females of the same species (i.e. cows proper), bulls have long been an important symbol in many religions, including for sacrifices. These animals play a significant role in beef ranching, dairy farming, and a variety of sporting and cultural activities, including bullfighting and bull riding.

Due to their temperament, handling of bulls requires precautions.

A eunuch (/ˈjuːnək/ YOO-nək) is a man who has been castrated. Throughout history, castration often served a specific social function. In China, castration included removal of the penis as well as the testicles (see emasculation). Both organs were cut off with a knife at the same time.

Eunuchs existed in the Chinese court starting around 146 AD during the reign of Emperor Huan of Han, and were common as civil servants as early as the time of the Qin dynasty. From those ancient times until the Sui dynasty, castration was both a traditional punishment (one of the Five Punishments) and a means of gaining employment in the Imperial service. Certain eunuchs gained immense power that occasionally superseded that of even the Grand Secretaries, such as the Ming dynasty official Zheng He. Self-castration was a common practice, although it was not always performed completely, which led to it being made illegal.

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, chemical castration does not remove organs and is not a form of sterilization.

Chemical castration is generally reversible when treatment is discontinued, although permanent effects in body chemistry can sometimes be seen, as in the case of bone density loss increasing with length of use of depot medroxyprogesterone acetate (DMPA). In men, chemical castration reduces sex drive and the capacity for sexual arousal, side effects of some drugs may include depression, suicidal ideation, hot flashes, anemia, infertility, increase in body fat and higher risks of cardiovascular diseases and osteoporosis. In women, chemical castration acts by decreasing testosterone levels in order to lower their sex drive, side effects include the deflation of breast glands, expansion of the size of the nipple and shrinking of bone mass.

Oophorectomy or Oöphorectomy (/ˌoʊ.əfəˈrɛktəmi/; from Greek ᾠοφόρος, ōophóros, 'egg-bearing' and ἐκτομή, ektomḗ, '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 non-human 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.

Attis (/ˈætɪs/; Ancient Greek: Ἄττις, also Ἄτυς, Ἄττυς, Ἄττης) was the consort of Cybele, in Phrygian and Greek mythology.

His priests were eunuchs, the Galli, as explained by origin myths pertaining to Attis castrating himself. Attis was also a Phrygian vegetation deity. His self-mutilation, death, and resurrection represents the fruits of the earth, which die in winter only to rise again in the spring.
