The controversy over male circumcision has once again reared its ugly head.  Once favored as a means to reduce the risk of infections and sexually transmitted diseases, then shunned in recent decades as unnecessary and painful for newborn baby boys, the cut is back and looking better than ever.

A new study, highlighted at last week's XVI International AIDS Conference in Toronto, has found that circumcision is almost as good as a high-quality vaccine at preventing HIV infection in South Africa.  An earlier study had found that circumcised men in sub-Sahara Africa were less than half as likely than uncircumcised men to contract HIV.  And the U.S. National Institutes of Health has green-lighted the continuation of circumcision studies in Uganda and Kenya.
