Prevalence of premature ejaculation and its correlation with chronic prostatitis in Chinese men.
OBJECTIVE
Chronic pelvic pain syndrome is a common and serious health problem affecting the quality of life of men. We evaluated the prevalence of premature ejaculation (PE) in Chinese men with chronic pelvic pain syndrome and studied its correlation to chronic prostatitis.


METHODS
A total of 15,000 men (aged 15-60 years) were randomly recruited to take part in a survey to provide questionnaire-elicited information for sociodemographics, sexual function, National Institutes of Health-Chronic Prostatitis Symptom Index, and International Index of Erectile Function 5-item questionnaire. The eligible subjects of the present investigation were married with sexual activity.


RESULTS
Responses were collected from 12 743 men (84.95%). Of these men, 1071 (8.4%) reported having prostatitis-like symptoms. The incidence of chronic prostatitis was 4.5% (n = 571) for the entire group. Of the 7372 eligible men, the incidence of prostatitis-like symptoms, chronic prostatitis, and PE was 10.5% (n = 771), 5.0% (n = 370), and 15.3% (n = 1127), respectively. The group with PE had worse National Institutes of Health-Chronic Prostatitis Symptom Index scores (P < .05) and lower International Index of Erectile Function 5-item questionnaire scores (P < .05) than the patients without PE. Also, the percentage of prostatitis-like symptoms in the PE group was greater than that in the non-PE group (P < .05). The prevalence of PE was 64.1% and 36.9% in the prostatitis-like symptom and chronic prostatitis group, respectively, of the 7372 eligible men.


CONCLUSIONS
The results of our study showed a high prevalence of PE in patients with chronic prostatitis. An examination of the prostate, physically and microbiologically, should be considered during the assessment of patients with PE.
