Castration, gelding, neutering, orchiectomy, or orchidectomy is any action, surgical, chemical, or otherwise, by which a biological male loses 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 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 t ...

Castration - 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, Africa or 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 ...

Chemical castration is a form of castration caused by certain hormonal drugs. It was developed as a temporary preventive measure and punishment usually reserved for male sex offenders, typically child molesters and rapists. For male sex offenders, chemical castration is considered more humane than actual castration, and additionally it is not permanent. However the ACLU has condemned it as unconstitutional and a form of cruel and unusual punishment. In addition to ethical concerns, chemical castration may increase blood pressur ...

A eunuch is an infertile human male whose testicles have either been removed (deliberately or by accident) or are otherwise non-functional. The earliest records for intentional castration to produce eunuchs are from the Sumerian city of Lagash in the 21st century B.C. Over the millennia since, they have performed a wide variety of functions in many different cultures such as courtiers or equivalent domestics, treble singers, religious specialists, government officials, military commanders, and guardians of women or harem servants. ...

Located deep in the brain's medial temporal lobe, the almond-shaped amygdala (in Latin, corpus amygdaloideum) is believed to play a key role in the emotions. It forms part of the limbic system. In humans and other animals, this subcortical brain structure is linked to both fear responses and pleasure. Its size is positively correlated with aggressive behavior across species. In humans it is the most sexually dimorphic brain structure, and shrinks by more than 30% in males upon castration. Conditions such as anxiety, autism, dep ...

Castration anxiety is an idea put forth by Sigmund Freud in his writings on the Oedipus complex; it posits a deep-seated fear or anxiety in boys and men said to originate during the genital stage of sexual development. It asserts that boys, when seeing a girl's genitalia, will falsely assume that the girl had her penis removed, probably as punishment for some misbehavior. The boy then becomes anxious lest the same happen to him. It is worth noting that in some cultures, notably 19th century Europe, it was not unheard of for par ...

The testicles, known medically as testes (singular testis), are the male generative glands in animals. Male mammals have two testicles, which are often contained within an extension of the abdomen called the scrotum. In mammals the testes are located outside of the body as they are suspended by the spermatic cord and within the scrotum. This is due to the fact that spermatogenesis is more efficient at a temperature somewhat less than the core body temperature of 37 degrees Celsius (98.6 degrees Fahrenheit). The cr ...

Sterilization is a surgical technique leaving a male or female unable to procreate. It is a method of birth control. A vasectomy in males. The vasa deferentia, the tubes which connect the testicles to the prostate, are cut and closed. This prevents sperm produced in the testicles to be in the ejaculated semen fluid (which is mostly produced in the prostate and the seminal vesicles). A tubal ligation in females. The Fallopian tubes, which allow the sperm to fertilize the ovum and would carry the fert ...

Body art is art made on, or consisting of, the human body. The most common forms of body art are tattoos and body piercings, but also includes scarification, branding, scalpelling, shaping (for example tight-lacing of corsets), and body painting. More extreme body art can involve mutilation, or in some way pushing the body to its limits. One of Marina Abramovic's works, for example, consisted of her dancing until she collapsed from exhaustion, while one of Dennis Oppenheim's better known works saw him lying in the sunlig ...

Feminists generally regard this theory as sexist. In turn, feminists themselves have been accused of suffering from penis envy, as traditionally masculine traits have been valued over feminine ones by many 20th Century and 21st Century feminists. Historically, feminists have explained that penis envy existed as the result of a male-dominated patriarchy, and "penis envy" was the understandable frustration and desire to participate in the power structure, which oppressed women. Women were denied entry into business and academia, and medicine a ...

Some men have penile amputations, known as penectomies, for medical reasons. Cancer, for example, sometimes necessitates removal of all or part of the penis. In very rare instances, botched childhood circumcisions have also resulted in full or partial penectomies. Genital surgical procedures for transwomen (transgendered or transsexual women) undergoing sex reassignment surgery, do not usually involve the complete removal of the penis; part or all of the glans is usually kept and reshaped as a clitoris, and the skin of the penile shaf ...

Trematodes are commonly referred to as flukes. This term can be traced back to the Saxon name for Flounder, and refers to the flattened, rhomboidal shape of the worms. There are no known cases of human infection with Aspidogastreans, therefore the use of the term "fluke" in relation to human infection refers solely to digenean infections. The flukes can be classified into two groups, on the basis of the system which they infect. Tissue flukes, are species which infect the bile ducts, lungs, or other biological tis ...

Trap-Neuter-Return begins with the trapping of feral cats using humane cage traps. The captured feral cats are taken (in the trap) to a veterinary clinic where they are sterilized by the castration of males and spaying of females. Typical TNR programs also involve providing the cats vaccinations against certain diseases like rabies, feline panleukopenia, herpes, and calicivirus. Finally the cats are marked so that they can be easily identified as a sterilized feral, usually by cropping the pointed end of the ear so that it has a square appearance (known as ear tipping) or ...

Hesiod

(c 700 bc) A Greek poet In the Theogony he describes the genealogy of the Olympian gods, of whom Zeus was king, and how they came to power and suppressed revolts against their authority.

After praising the muses, divine patrons of the arts, the poet describes the origin of the universe in terms of mating and procreation. The first ruler of the gods was Ouranos ("Sky") and Gaia ("Earth"). Ouranos was overthrown by his children, the Titans, led by Kronos, who castrated his father. Kronos swallowed his own children by Rhea, until she tricked him by giving him a stone to swallow in place of the infant Zeus, who grew up to overthrow his father. The succession of dynasties clearly reflects the succession myth known in the ancient Near East.

For Hesiod, Zeus is not only the ultimate victor in the struggles between the gods but the guarantor of justice and human morality.
