Extract
Objective
Besides lifelong premature ejaculation (LPE) and acquired premature ejaculation (APE), Waldinger and Schweitzer proposed two addition PE syndromes (Natural variable PE [NVPE] and Premature-like ejaculatory dysfunction [PLED]). We assessed the associations between 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., Intravaginal Ejaculatory Latency Time [IELT], and self-estimated scales (e.g., NIH-CPSI).
Results
Of 3,016 of the men evaluated, 25.80% complained of PE. Distribution of the four PE syndromes among men with complaints of PE was as follows: LPE, 12.34%; APE, 18.77%; NVPE, 44.09%; PLED, 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 PLED. 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).
