About the Project

Rationale

International research has demonstrated that effective antiretroviral therapy can substantially decrease the risk of HIV transmission in heterosexual serodiscordant couples. This study explores the effectiveness of “treatment as prevention” in gay male serodiscordant couples.

Aims

To determine if HIV incidence in HIV negative men in serodiscordant relationships is associated with whether the HIV positive partner is on antiretroviral therapy, and to explore the extent to which HIV viral load is used in negotiating unprotected sex within serodiscordant couples.

Design & Method

Prospective cohort study of gay male serodiscordant couples. Results of HIV viral load tests and CD4 counts (in HIV positive partners) and HIV antibody tests (in HIV negative partners) are recorded at up to four clinic visits per year. At each visit, questionnaires are completed concerning sexual behaviour, attitudes, knowledge, treatments, and communication. A subsample of HIV positive men participate in a Semen Sub-Study tracking HIV viral load in semen.  

Progress/Update

The study starts recruitment in early 2012.

Benefits

The Opposites Attract Study will provide globally unique data on the role of HIV antiretroviral treatments in preventing HIV transmission in gay male serodiscordant couples.
