Affects

Given the lack of cleanliness, it is not unexpected that female circumcision comes with many complications. In fact, there are no health benifits at all; it is a procedure that is intended to make the body look more beautiful on the outside, while the inside starts to fall apart.

Female genital mutilation causes severe bleeding, especially when the operation is being done. Since the instruments used are so unprofessional in their nature, it is not uncommon for the victims to lose a large amount of blood, which could be fatal. The victim will mostly likely experience serious infections and problems urinating after the operation and later on in life as well. In the future, cysts could form in the body of the victim because female circumcision  often affects the menstrual cycle. Sometimes the hole is not wide enough to let the menstrual blood flow so it remains in the body and causes exremely serious infections and complications. Complications are also present with childbirth and fertility. Girls who have undergone female circumcision are at a higher risk of giving birth to a still born baby, or having a newborn death, presumeably because the vaginal hole has been narrowed to such an extent that it affects the newborns ability to exit the body safely.

Aside from the medical affects, female genital mutilation affects the girl's emotionally and mentally. Every woman who has been asked to describe the day they were circumcised testifies that it was the most traumatic experience of their lives; the pain was so immense that they had wished death upon themselves rather than continue on with the procedure. For the rest of their lives they often live in fear of engaging in sexual reproduction because of the pain they know it will bring. They often develop trust issues with the family members that encouraged/tricked them into getting the operation done, and some cases of Post Traumatic Stress Syndrome have been found with the victims as well.
