This article, published in the Journal of Infectious Diseases, examined the association between male circumcision and the risk of HIV infection among a subset of heterosexual men in the U.S.
Electronic clinic records were reviewed for heterosexual African American men who were HIV tested between 1993-2000. The patients were divided as to whether they had a “known HIV exposure” or “unknown HIV exposure.” Their HIV test results and whether they were circumcised were recorded.
The results showed that for African American men in Baltimore with known HIV exposure, circumcision reduces the risk of heterosexually acquired HIV infection. This result is consistent with three other published randomized studies from South Africa, Uganda and Kenya.
