Antiretroviral treatment means that an increasing number of men who have sex with men (MSM) are living with HIV.

Antiretroviral treatment means that an increasing number of men who have sex with men (MSM) are living with HIV. The present review focuses on continuing transmission of HIV, risk factors for HIV infection in HIV-negative MSM, risk behaviour and risk reduction interventions among HIV-positive MSM, sexually transmitted infections, HIV and ageing and new and emerging populations of MSM communities.

Transmission of HIV infection continues in populations of MSM; transmission may be particularly high from main partners. Serosorting offers limited protection against HIV infection for HIV-negative MSM; negotiated safety and strategic positioning may be partially protective. For HIV-positive men, serosorting is a strategy to prevent HIV transmission, but has contributed to high rates of new non-HIV sexually transmitted infections. Sexual networks are important to the understanding of emerging sexually transmitted infections; ageing brings a new dimension to research on HIV.
