Abstract:
PURPOSE: Lower urinary tract symptoms and erectile dysfunction both have a profound impact on the quality of life elderly men, but there are few reports that would enable us to clearly elucidate the relation between them. We investigated the prevalence of erectile dysfunction and its correlation with the severity of lower urinary tract symptoms as judged by the International Prostatic Symptom Score (I-PSS). MATERIALS AND METHODS: The total sample was 855 men aged 30 years and older (653 aged over 50) in 31 randomly selected areas of Jeong-Eup, Korea. Two questionnaires were sent. The first, on sexual activities, was based on DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th ed.) and was composed of several questions on the frequency of sexual intercourse, erectile ability, and the degree of any erectile dysfunction. The second, for men over 50 years of age, was the I-PSS. We analyzed the results with multivariate logistic analysis using an SAS program running on a personal computer. RESULTS: The response rate was 71.3% (466/653), and data sexual activities and I-PSS from 304 men were suitable for analysis. The prevalence of erectile dysfunction, defined as inability to achieve an erection sufficient for penetration, was 58.9% (179/304), and increased with age: 37.2% in men in their 50s, 69.2% in men in their 60s, 83.3% in men in their 70s, ans 100% in men over age: 37.2% in men in their 50s, 69.2% in men in their 60s, 83.3% in men in their 70s, and 100% in men over age 80 (p = 0.001). According to the intensity of lower urinary tract symptoms - mild (0-7), moderate (8-19), and severe (20-35) - the prevalence of erectile dysfunction was 46.6% (75/161), 68.8% (75.109), and 85.3% (29.34), respectively, and the prevalence of complete erectile dysfunction was 8.7% (14.161), 20.2% (22.109), and 47.1% (16.34), respectively. After adjustment for age, there was a statistically significant correlation between the severity of lower urinary tract symptoms and erectile dysfunction with the odds ratios being 2.395 and 4.125 in the moderately and severely symptomatic groups. CONCLUSIONS: There was a significant correlation between the presence of lower urinary tract symptoms and erectile dysfunction. We suggest that these two conditions are closed related by pathophysiologic mechanism, although clinical and basic research should be advanced to clarify the relation between them.
