Relationship between premature ejaculation and chronic prostatitis/chronic pelvic pain syndrome.

Abstract

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common etiology of premature ejaculation (PE). However, the current data are insufficient to explain this relationship and to support routine screening of men with PE. This study aims to evaluate the relationship between PE and CP/CPPS. A cross-sectional study was conducted that included 8,261 men who had participated in a health examination. The Premature Ejaculation Diagnostic Tool (PEDT), the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), and the International Index of Erectile Function-5 (IIEF) were used for assessment of symptoms. A full metabolic work-up and serum testosterone level checks were also performed. We then investigated the relationship using the Spearman correlation test, multiple linear regression, and logistic regression analyses. Associations of PEDT with NIH-CPSI. The mean age was 50.4 ± 5.5 years. In total, 2,205 (24.9%) men had prostatitis-like symptoms (NIH-CPSI pain score of ≥4 and perineal or ejaculatory pain), and 618 (7.0%) men had moderate to severe symptoms (NIH-CPSI pain score of ≥8). Additionally, 2,144 men (24.2%) were classified as demonstrating PE (PEDT > 10). The PEDT score was found to have a significant positive correlation with the NIH-CPSI pain domain score (correlation coefficient = 0.206; P < 0.001). After adjusting for age, metabolic syndrome status, testosterone level, and IIEF score, there was no change in the positive correlation between the NIH-CPSI pain domain score and PEDT score (Beta = 0.175; P < 0.001). After adjusting for age, testosterone level, metabolic syndrome, and IIEF score, the odds ratio (OR) for PE significantly increased with the severity of pelvic pain (mild prostatitis-like symptoms, OR for PE: 1.269, 95% confidence interval: 1.113-1.447; moderate to severe symptoms, OR for PE: 2.134: 95% confidence interval: 1.782-2.557). Our data showed a significant correlation between the PEDT score and the NIH-CPSI score. We suggest routine screening for CP/CPPS in men with PE and PE in men with CP/CPPS.
