I would do it to my son because now it is know to help prevent AIDS infection, so I would do it.....
"Going through previous analyses, researchers found that circumcision reduced the risk of HIV infection in men by 50% and by 70% in the highest-risk men. A new study included over 300 couples from Uganda where transmission came from men and showed that 299 women caught HIV from uncircumcised partners and only 44 from circumcised."
These studies fail to consider demographics. In Uganda, circumcised men are Muslims, who are likely to have had fewer partners.
Rather than cutting off parts of his body, wouldn't it be better to make sure your son is instructed in safe sex methods?
Certainly the vast majority of male AIDS deaths in the USA were circumcised men, it didn't help them one bit.
