A recent study conducted by Lance Price of the Translational Genomics Research institute (TGen) and his colleagues, showed that circumcision lowers the chances of contracting HIV. They conducted a detailed genetic analysis of microbes among a group of Ugandan men using the latest technology, before circumcision and again a year later after circumcision. The results were pretty dramatic. Circumcised men carried way fewer bacteria that contribute to easier HIV entrance by lowering the immune defenses than uncircumcised men. Circumcision lowers the risk of transmitting HIV by as much as 50%.
