Predicting risk of erectile dysfunction in patients with nonalcoholic fatty liver disease

Nonalcoholic fatty liver disease (NAFLD) is one of the risk factors for erectile dysfunction (ED). We aimed to predict the risk of ED in patients with NAFLD. The study included 146 male patients complaining impotence admitted to the urology outpatient clinic aged 24-80 years without a history of alcohol use who underwent abdominal ultrasonography between February 2018 and January 2019. 106 patients with NAFLD and 40 men without NAFLD were included in the study. Clinical and laboratory parameters, ED status according to International Index of Erectile Function-5 were compared between patients with and without NAFLD. The mean age of patients was 51.47 ± 10.34 years. NAFLD was detected in 72.6% of the patients. No statistically significant difference was found regarding mean age, BMI, IIEF-5 scores, DM status, serum glucose levels (p > .05). Fasting insulin levels, hypertension (HT), insulin resistance (IR) and ED status of the patients with NAFLD were significantly higher than patients without NAFLD (p < .05). NAFLD was found to be a significantly independent associated with ED. We also found that patients with NAFLD have risk of ED 2.92 times higher than without NAFLD (OR: 2.92). For the patients presenting with erectile dysfunction, hepatic steatosis should also be considered.
