Objective: We assessed the associations between intravaginal ejaculatory latency time (IELT) and National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) in men with different PE syndromes.

Methods: From September 2011 to September 2012, a total of 4,000 men were enrolled from the Anhui province of China. Subjects were required to complete a verbal questionnaire, including demographic information, medical and sexual history (e.g., IELT), and self-estimated scales (e.g., NIH-CPSI).

Results: Of 3,016 of the men evaluated, 25.80% complained of premature ejaculation (PE). Distribution of the four PE syndromes among men with complaints of PE was as follows: LPE, 12.34%; APE, 18.77%; VPE, 44.09%; and SPE, 24.81%. Men with complaints of PE reported worse NIH-CPSI scores and lower IELT than men without complaints of PE (P<0.001 for all). Moreover, total and subdomain scores of NIH-CPSI were higher in men with APE, and IELT was higher in men with SPE. IELT was negatively associated with NIH-CPSI scores in men with complaints of PE. Negative relationships between total and subdomain scores of NIH-CPSI and IELT were stronger in men with APE (total scores: adjusted r=−0.68, P<0.001; pain symptoms: adjusted r=−0.70, P<0.001; urinary symptoms: adjusted r=−0.67, P<0.001; quality of life impact: adjusted r=−0.64, P<0.001).

Conclusions: Men with complaints of PE reported worse NIH-CPSI scores than men without complaints of PE. Relationships between IELT and NIH-CPSI scores were strongest in men with APE.
