Types of female genital mutilation
Type Description Type I (Clitoridectomy) Removing part of the clitoris Type II (Excision) Parital or total removal of the clitoris and the labia minora. The labia majora may also be removed. Type III (Infibulation) The vaginal opening is narrowed by a covering seal. The outer lips are then sewn together leaving a small hole to allow urine and menstrual blood to leave the body. There may also be partial or total removal of the clitoris, and inner and outer labial lips. The outer lips are then sewn together leaving a small hole to allow urine and menstrual blood to leave the body Type IV Any other harm caused to the genitalia, e.g., piercing, prickling, scraping, pulling, stretching, or burning
