Last spring in Feminist Theory, my group did a presentation on Female Genital Mutilation (now called female genital cutting in deference to those who practice it). Of couse, I had the balls to bring up Male circumcision, for perspective. Talking about penises in a room full of feminists? Haha.
I did get most of my research from
http://www.cirp.org, which isn't quite unbiased, I think, but it does have really extensive info and was quite helpful. I could talk about why I think circumcision shouldn't take place in infancy, but a lot of people have already covered my points.
I'll add just one: at a few days old, the penis is not fully developed, and it can expose tissue that's still growing to bacteria from excretia in the diaper, etc. Sorry, that wasn't quite articulate. (I view it a bit like peeling apart two layers that aren't quite separated yet.) To elucidate, foreskin helps keep the head moist, hardening can decrease sensitivity in the future (the skin of the glans hardens a bit over time).
But then, I don't have a penis, so can only rely on what I read/experience.
In terms of FGM, it is much more extreme than male circumcision in most cases. Also, strangely enough, most women welcome it. Both are very *cultural* procedures. In societies practicing FGM, it is seen as the norm. In order to be a woman (and eligible for marriage and having a family) you must have it done. It is often done as part of a right of passage, and the elder women do it. It is sometimes done with glass, though. Most women want it because otherwise they will be different, they will not be accepted, they will not find a husband, they will not honor their families, etc.
Some parents decide to circumcise so they're son looks like his father or the other boys at school. Another instance of cultural pressures. *shrug*
Could be wrong, but this is how I've come to understand things. If I ever have children I don't plan on circumcising them, I will leave that decision up to them.
