A news release from the World Health Organization (WHO) summarises the highlights of updated guidelines based on more than 10 years of further evidence that voluntary medical male circumcision (VMMC) for HIV prevention is having a substantial effect in real-world settings. It describes how the new VMMC guidelines present the latest evidence on the impact and cost-effectiveness of VMMC services, the safety of the use of prequalified devices to perform male circumcision, and interventions to enhance uptake of VMMC services among men.
