According to a 2005 World Health Organization estimate, about 97.9% of Somalia's women and girls underwent Female genital mutilation, a pre-marital custom mainly endemic to the horn of Africa and parts of the Near East. Encouraged by women in the community, it is primarily intended to protect chastity, deter promiscuity, and offer protection from assault. By 2013, UNICEF in conjunction with the Somali authorities reported that the prevalence rate among 1- to 14-year-old girls in the autonomous northern Puntland and Somaliland regions had dropped to 25% following a social and religious awareness campaign. About 93% of Somalia's male population is also reportedly circumcised.
