In Sudan in 2006, a significant percentage of infibulated women and girls reported a less severe type. Types
Standard questionnaires from United Nations bodies ask women whether they or their daughters have undergone the following: (1) cut, no flesh removed (symbolic nicking); (2) cut, some flesh removed; (3) sewn closed; or (4) type not determined/unsure/doesnt know. The most common procedures fall within the "cut, some flesh removed" category and involve complete or partial removal of the clitoral glans. The World Health Organization (a UN agency) created a more detailed typology in 1997: Types I–II vary in how much tissue is removed; Type III is equivalent to the UNICEF category "sewn closed"; and Type IV describes miscellaneous procedures, including symbolic nicking. Type I
Type I is "partial or total removal of the clitoral glans (the external and visible part of the clitoris, which is a sensitive part of the female genitals), and/or the prepuce/clitoral hood (the fold of skin surrounding the clitoral glans)". Type Ia involves removal of the clitoral hood only. This is rarely performed alone. The more common procedure is Type Ib (clitoridectomy), the complete or partial removal of the clitoral glans (the visible tip of the clitoris) and clitoral hood. The circumciser pulls the clitoral glans with her thumb and index finger and cuts it off. Type II
Type II (excision) is the complete or partial removal of the inner labia, with or without removal of the clitoral glans and outer labia.
Christian missionaries in Africa were among the first to object to FGM, but Christian communities in Africa do practise it. In 2013 UNICEF identified 19 African countries in which at least 10 percent of Christian women and girls aged 15 to 49 had undergone FGM; in Niger, 55 percent of Christian women and girls had experienced it, compared with two percent of their Muslim counterparts. The only Jewish group known to have practised it is the Beta Israel of Ethiopia. Judaism requires male circumcision but does not allow FGM. FGM is also practised by animist groups, particularly in Guinea and Mali. History
Antiquity
The practices origins are unknown. Gerry Mackie has suggested that, because FGMs east–west, north–south distribution in Africa meets in Sudan, infibulation may have begun there with the Meroite civilization (c. 800 BCE – c. 350 CE), before the rise of Islam, to increase confidence in paternity. According to historian Mary Knight, Spell 1117 (c. 1991–1786 BCE) of the Ancient Egyptian Coffin Texts may refer in hieroglyphs to an uncircumcised girl (mt):

The spell was found on the sarcophagus of Sit-hedjhotep, now in the Egyptian Museum, and dates to Egypts Middle Kingdom. (Paul F. ORourke argues that mt probably refers instead to a menstruating woman.) The proposed circumcision of an Egyptian girl, Tathemis, is also mentioned on a Greek papyrus, from 163 BCE, in the British Museum: "Sometime after this, Nephoris [Tathemiss mother] defrauded me, being anxious that it was time for Tathemis to be circumcised, as is the custom among the Egyptians.
