Background and Aim: Erectile dysfunction (ED) is an important and commonly seen disorder in patients with non-alcoholic fatty liver disease (NAFLD). The objective of this study was to assess the rate of ED and its causes in a group of NAFLD patients. Materials and Methods: The International Index of Erectile Function questionnaire (IIEF-5) was used to evaluate the presence, causes, and severity of ED. Participants with an IIEF-5 score of <22 who agreed to undergo a urological evaluation were referred to a urologist for further assessment. Results: A total of 136 NAFLD patients were enrolled in the study. According to the IIEF-5, 68 (50.0\%) patients had ED. Multivariate analysis indicated that older age, obesity, and hypertension were associated with ED. Seventeen patients had multiple etiological factors for ED. Psychogenic ED was identified in 19 patients (39.6\%), vasculogenic ED in 35 patients (72.9\%), drug-related ED in 3 patients (6.3\%), and neurogenic ED in 6 patients (12.5\%). Conclusion: ED is frequently seen in NAFLD patients, which may, at least in part, be due to common risk factors. vasculogenic dysfunction is the most common single source of ED in NAFLD patients. Nonetheless, all potential etiologies should be carefully investigated, with special attention given to psychogenic factors, since they may be more frequent and relevant than expected.
