Um, we learned about this topic in passing during 9th grade. Apparantly, it is prevalent in Africa and it involves cutting off women's clitorises so that they won't be able to feel pleasure in sex and as a result will not seek promiscous activity. In cultures that practice it, it is supposedly the female equivalent of male circumcision. But do cross-reference my sources, I could have been taught biased or inaccurate information.

I actually wrote a research paper on Female Genital Mutilation for my World Civ. class last year and I found all my information on the internet.

Just type "Female Genital Mutilation" or "Female Genital Cutting" into your search engine. also try "Female Circumcision".
