Effect of the Severity of Chronic Prostatitis Symptoms on Premature Ejaculation among Korean Males in Their 40-50s

Abstract

Purpose: The purpose of this study was to analyze the effect of the severity of chronic prostatitis symptoms on premature ejaculation among Korean males in their 40-50s. Materials and Methods: From September 2011 to December 2012, we conducted a survey targeting 319 Koreans who had undergone medical examinations in our institution, using National Institute of Health chronic prostatitis symptom index (NIH-CPSI) and premature ejaculation diagnostic tool (PEDT). Results: The average age of 319 volunteers was 50.8 years (40-59), the average total NIH-CPSI score was 8.6±6.2. And total PEDT score was 7.7±5.0. Twenty eight persons had chronic prostatitis-like symptoms (8.8%). Statistically significant differences in the prevalence of premature ejaculation were observed between persons with chronic prostatitis-like symptoms (82%) and those without (37.5%). In the same manner, the prevalence of premature ejaculation was higher in the moderate and severe symptom groups than in the mild symptom groups according to the symptom scale score (pain plus voiding score) and total score of NIH-CPSI (mild: 38.2%, moderate/severe: 59.6% by symptom scale score and mild: 36.7%, moderate/severe: 65.4% by total score). In univariate and multivariate analyses, presence or absence of chronic prostatitis-like symptoms and classification according to total NIH-CPSI score were independent predictive factors for the prevalence of premature ejaculation on PEDT. Conclusions: Significant statistical relationships were observed between NIH-CPSI and PEDT in Korean males in their 40-50s who have chronic prostatitis-like symptoms or were classified into moderate and severe symptom groups according to total NIH-CPSI score.
