Circumcision
Circumcision is very important to most branches of Judaism, with over 90% of male adherents having the procedure performed as a religious obligation. The basis for its observance is found in the Torah of the Hebrew Bible, in Genesis chapter 17, in which a covenant of circumcision is made with Abraham and his descendants. Jewish circumcision is part of the "brit milah" ritual, to be performed by a specialist ritual circumciser, a "mohel", on the eighth day of a newborn son's life, with certain exceptions for poor health. Jewish law requires that the circumcision leaves the glans bare when the penis is flaccid. Converts to Conservative and Orthodox Judaism must also be circumcised; those who are already circumcised undergo a symbolic circumcision ritual. Circumcision is not required by Judaism for one to be considered Jewish, but some adherents foresee serious negative spiritual consequences if it is neglected.
History of male circumcision
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. In Judaism, circumcision has traditionally been practised among males on the eighth day after birth. Male 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. 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%.
