The origin of circumcision is not known with certainty. It has been variously proposed that it began

as a religious sacrifice;

as a rite of passage marking a boy's entrance into adulthood;

as a form of sympathetic magic to ensure virility or fertility;

as a means of reducing sexual pleasure;

as an aid to hygiene where regular bathing was impractical;

as a means of marking those of higher social status;

as a means of humiliating enemies and slaves by symbolic castration;

as a means of differentiating a circumcising group from their non-circumcising neighbors;

as a means of discouraging masturbation or other socially proscribed sexual behaviors;

as a means of increasing a man's attractiveness to women;

as a demonstration of one's ability to endure pain;

as a male counterpart to menstruation or the breaking of the hymen;

to copy the rare natural occurrence of a missing foreskin of an important leader;[5][6]

as a way to repel demonesses;[7] and/or

as a display of disgust of the smegma produced by the foreskin.

Circumcision has ancient roots among several ethnic groups in sub-equatorial Africa, and is still performed on adolescent boys to symbolize their transition to warrior status or adulthood.[1] Circumcision and/or subincision, often as part of an intricate coming of age ritual, was a common practice among Australian Aborigines and Pacific islanders at first contact with Western travellers. It is still practiced in the traditional way by a proportion of the population.[2][3][full citation needed]

In Judaism, circumcision has traditionally been practised among males on the eighth day after birth. The Book of Genesis records circumcision as part of the Abrahamic covenant with Yahweh (God). Circumcision was common, although not universal, among ancient Semitic people.[citation needed] Herodotus, writing in the 5th century BCE, lists the Colchians, Ethiopians, Phoenicians, and Syrians as circumcising cultures. In the aftermath of the conquests of Alexander the Great, however, Greek dislike of circumcision (they regarded a man as truly "naked" only if his prepuce was retracted) led to a decline in its incidence among many peoples that had previously practiced it.[citation needed] The writer of 1 Maccabees wrote that under the Seleucids, many Jewish men attempted to hide or reverse their circumcision so they could exercise in Greek gymnasia, where nudity was the norm. First Maccabees also relates that the Seleucids forbade the practice of brit milah (Jewish circumcision), and punished those who performed it, as well as the infants who underwent it, with death.[citation needed]

According to “National Hospital Discharge Survey” in United States, as of 2008, the rate of circumcision of infant boys in hospitals in United States was 55.9%
