Dolutegravir, the anchor drug of combination antiretroviral therapy (cART), has been associated with sexual dysfunction. We have evaluated the burden, correlates and nature of sexual dysfunction among Ugandan males living with HIV receiving dolutegravir-based antiretroviral therapy. In a cross-sectional study in one health centre, we collected sociodemographic and clinical data via structured interviews, undertook clinical examinations and performed data abstraction from electronic medical records. Sexual function was evaluated using the International Index of Erectile Function and the Changes in Sexual Functioning Questionnaire. Modified Poisson regression was utilised to estimate prevalence ratios (PRs), modelling dolutegravir exposure as the primary independent variable while adjusting for sociodemographic and clinical factors as secondary covariates. The prevalence of erectile dysfunction among males receiving dolutegravir-based cART for > 1 day to 6 months was twice that of cART-naive males (59
