Factors associated with erectile dysfunction among men living with HIV: a systematic review.

Erectile dysfunction (ED) is more prevalent among men with HIV than HIV negative men. This study systematically reviewed quantitative studies published since 1997 which sampled men with HIV to examine factors associated with ED. Searches on PsycINFO, Medline, Scopus, Embase and Cinahl databases produced 5552 records, and 14 studies met inclusion criteria. Two researchers independently extracted data and assessed the quality studies using standardized criteria. Age and depression were found to be significantly associated with ED. Importantly, factors unique to HIV emerged as consistently significant across studies, including time on antiretroviral medication and protease inhibitor medication use. However, these relate to organic cause factors associated with ED only. Only four studies examined social factors with inconsistent findings. There was a paucity of research related to psychosocial factors associated with ED. This systematic review used a broad search strategy employed across multiple data-bases, however, it is limited by the over-representation of treatment centre based studies conducted in high-income nations. Future research should examine psychosocial factors, such as undue fear of transmission of HIV or fear of rejection by a sexual partner and develop a psychosocial model of sexual difficulties with HIV, from which casual hypotheses can be derived and tested.
