Uptake and acceptability of medical male circumcision among young males in two culturally distinct settings in South Africa: A longitudinal, community-based study (the MACHO study).

Background: Young South Africans experience high rates of HIV infection. While nationally scaled medical male circumcision (MMC) can help to curb HIV infection rates in countries such as South Africa (SA), MMC uptake has not been consistent or universal, suggesting variable acceptability among men. Both MMC and traditional male circumcision (TMC) are practised in SA.
