Circumcision may stop millions of HIV deaths
Circumcising men routinely across Africa could prevent millions of deaths from AIDS, World Health Organization researchers and colleagues reported Monday.
They analyzed data from trials that showed men who had been circumcised had a significantly lower risk of infection with the AIDS virus, and calculated that if all men were circumcised over the next 10 years, some two million new infections and around 300,000 deaths could be avoided.
