Abstract:
Randomized clinical trials (RCTs) have shown that medical male circumcision (MC) substantially reduces the risk of female-to-male HIV transmission.1 Driven by this evidence base, a growing number of countries have adopted large-scale MC campaigns in an effort to prevent heterosexually acquired HIV in men. In South Africa, for example, >130,000 medical male circumcisions were performed during 2010.2Encouraging adoption of MC will require educating millions of men and women about its protective benefits. The success of these policies will depend critically on what people infer from prevention information and the actions they take as a result.
