From the WHO; http://www.who.int/hiv/topics/malecircumcision/en/
The push against male circumcision today appears to be primarily from those who believe it horrifically painful or barbaric, or reject it because people associate it with religion. Having been present when my son was circumcised (in a hospital), I assure you it is neither. I allowed it because I was aware of the impact on STD transmission. I wish more were aware of the benefits. There would be several hundred thousand fewer orphans in Africa.
