Lower Urinary Tract Symptoms Correlate with Erectile Dysfunction and Premature Ejaculation but Not with Men's Sexual Activity: Results from a Large Population-Representative Study

Background: Lower urinary tract symptoms (LUTS) contribute to erectile dysfunction (ED) and premature ejaculation (PE). However, only a few studies have been conducted with representative groups of men that had well-balanced demographic characteristics. Thus, we aimed to confirm the effect of LUTS on ED and PE and to analyze the association between LUTS and men's sexual activity in a large representative cohort. In addition, we evaluated the sex-specific and overall quality of life of men who had LUTS with either ED or PE. Methods: We used the latest census and estimated the sample size to build a group of men representative of the population. LUTS, ED, and PE were evaluated with reliable instruments. Regression models were used to analyze the data. Results: All included men were representative in relation to their age and residential location (n = 3001). ED and PE were more common in men who reported LUTS compared with men who did not have LUTS (p < 0.001). Age, comorbidity, and lifestyle did not affect the negative effect of LUTS on ED or PE (regression coefficients of 0.159 and 0.528 for ED and PE, respectively, p < 0.001). However, regression models did not validate the impact of LUTS on sexual activity, defined by intercourse frequency and number of sexual partners (odds ratio of 0.981, CI 0.961-1.001, p = 0.061). Nevertheless, men with LUTS and either ED or PE had worse quality of sexual life and general quality of life compared with the remaining respondents. Conclusion: LUTS worsened ED and PE but had no impact on men's sexual activity. Our findings confirm the recommendations to assess for LUTS in men reporting ED or PE. Clinical Trial Registration: The study was registered with ClinicalTrials.gov (NCT05462171).
