"Three randomised studies in countries with high HIV rates - South Africa, Tanzania and Uganda - have confirmed that male adult medical circumcisions can reduce HIV transmission from women to men by as much as 60 per cent, and from men to women by about 15 per cent. This significant reduction in HIV transmission also correlates with the reduction in transmission of other sexually transmitted diseases such as syphilis, herpes, hepatitis and HPV (Human Papilloma Virus)."
