Introduction:
Lower urinary tract symptoms (LUTS) affect ≥60% of adult men and are associated with erectile dysfunction (ED) and sexual dissatisfaction.
Aim:
The aim of this study was to evaluate the relationship among male LUTS, ED, and sexual satisfaction.
Methods:
This was a secondary analysis of the Brazil LUTS study, a cross-sectional, epidemiological survey conducted by telephone interview in 5 cities in Brazil. This analysis included men aged ≥40 years.
Main Outcome Measure:
LUTS were identified using International Continence Society definitions. LUTS severity was assessed using the International Prostate Symptom Score questionnaire. Erectile function was assessed using the International Index of Erectile Function-5 (IIEF-5) questionnaire and sexual satisfaction was rated on a 5-point scale.
Results:
2,433 men participated in the study. Of 2,183 men reporting data on LUTS, 873 (40%) had LUTS "about half the time" or more. The prevalence of ED and sexual dissatisfaction was 14.4% and 7.8%, respectively. The proportion of men reporting ED and sexual dissatisfaction was higher among men with LUTS (24.6% and 13.8%, respectively) than men without LUTS (8.7% and 4.5%, respectively; P < .001). LUTS severity was negatively correlated with IIEF-5 scores (r = -0.199; P < .001); we estimated a 0.431-point decrease in IIEF-5 score per 3-point increase in International Prostate Symptom Score. Increased age and the presence of LUTS were associated with a greater chance of ED and sexual dissatisfaction; depression/anxiety and diabetes were associated with a greater chance of sexual dissatisfaction only. Among men with LUTS, urgency with fear of leaking, urgency urinary incontinence, and nocturnal enuresis were associated with a greater chance of ED, whereas slow stream and urgency urinary incontinence were associated with a greater chance of sexual dissatisfaction.
Conclusion:
These results demonstrate that the presence of LUTS is associated with an increased chance of ED and sexual dissatisfaction in Brazilian men and reinforce the importance of a comprehensive assessment of these conditions.
