Trial among MSM finds protective effect

Voluntary medical male circumcision (VMMC) can reduce the risk of HIV acquisition among men who have sex with men who primarily practice insertive anal sex, a randomised controlled trial conducted in China has found. Previous trials had shown that being circumcised reduces men’s chances of acquiring HIV through vaginal sex, but the new study, presented at the International AIDS Society Conference on HIV Science in Brisbane, Australia, is the first to show the procedure may limit transmission among men who have sex with men. The authors conclude that large-scale trials may be needed to confirm efficacy (Healio, 21 July 2023).
