According to the World Health Organization (WHO), there are 140 Million circumcised women worldwide. The practice is spread throughout 28 African countries, mostly in northern, eastern and western Africa, but also in some Asian states and the Middle East.
There are various forms of circumcision that involve the removal of parts of the female genitalia for no medical purpose. In 1995 the WHO categorized the different forms of genital mutilation. From clitoridectomy, considered the “least harmful” type, to excision, the most widespread, and finally to the most devastating form known as infibulation. As a result, many girls and women suffer from severe, often chronic health problems, including pregnancy and birth complications, which can be fatal, and mental disorders.
