Erectile dysfunction (ED) is a common condition that affects men’s quality of life. Thus, a study was undertaken to highlight the comorbid associations of ED among the Lebanese population. Considering the high prevalence of smoking in Lebanon, dietary changes, and metabolic diseases, it is important to evaluate the role of these factors in ED. Thus our study analyzes how diabetes mellitus (DM), hypertension (HTN), and cardiovascular disease (CVD) correlate with the severity of ED.

This cross-sectional study assessed 150 Lebanese males diagnosed with DM, HTN, and/or CVD. The International Index of Erectile Function (IIEF-5) and comorbidity data were extracted from medical records provided by urologists and used to classify ED severity. Chi-square tests and multivariate logistic regression were performed to identify predictors of severe ED.

The mean age was 62.6 years, and the mean BMI was 28.3. Among participants, 40.7% had moderate ED, 31.3% had mild ED, 16.7% had severe ED, and 10% had normal erectile function. Hypertension was present in 83 patients, with 85.5% experiencing moderate to severe ED (χ² = 36.1, p < 0.001). Diabetes mellitus was the strongest predictor, with 75.9% of diabetic patients having severe ED (χ² = 42.1, p < 0.001). Cardiovascular disease had a weaker association (χ² = 7.6, p = 0.054).

The findings indicate that both diabetes and cardiovascular disease significantly contribute to the severity of erectile dysfunction, with diabetes being the most influential factor. These associations point to a strong vascular and metabolic component in ED pathophysiology and emphasize the need to address these comorbidities as part of comprehensive ED management.

Diabetes and hypertension are two important causes for severity of ED in Lebanese men. Although cardiovascular disease was not statistically significant, it should be further studied. Due to metabolic disorders common in Lebanon, using a multidisciplinary management approach can help alleviate the severity of ED.
