Antiretroviral therapy is associated with sexual dysfunction and with increased serum oestradiol levels in men

Abstract

Our objective was to determine the relationship between highly active antiretroviral therapy (HAART), serum total oestradiol and sexual dysfunction in HIV-infected men. Sexual difficulties were recorded prospectively in a cohort of HIV-negative (or unknown status) gay/bisexual men (MSM) and a cohort of HIV-infected men. The HIV-infected men were divided into those on and not on HAART and by sexuality. Serum total oestradiol and testosterone levels were evaluated where possible. One hundred HIV-negative MSM and 73 HIV-infected men (88% MSM) were analysed. Low libido and erectile dysfunction (ED) were reported in the control group in 2% and 10% respectively. This compared to a prevalence of 26% for both problems in HIV-infected MSM not taking HAART. In those MSM on HAART reduced libido was noted in 48% and ED in 25%. In the group of men taking HAART the mean oestradiol level was 228 pmol/L and was significantly above normal limits. Low libido and ED are more commonly reported in HIV-infected men compared to gay men of negative or unknown status. HAART is associated with a higher prevalence of lack of sexual desire and raised serum oestradiol levels.
