Relationships between intravaginal ejaculatory latency time and national institutes of health-chronic prostatitis symptom index in the four types of premature ejaculation syndromes: a large observational study in China

Introduction Besides lifelong premature ejaculation (LPE) and acquired premature ejaculation (APE), Waldinger and Schweitzer proposed two addition PE syndromes (variable PE [VPE] and subjective PE [SPE]). Aim 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). Main Outcome Measures IELT; NIH‐CPSI; the new classification of PE syndromes. 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%; 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 r = −0.68, P r = −0.70, P r = −0.67, P r = −0.64, P Conclusion 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. Gao J, Xu C, Liang C, Su P, Peng Z, Shi K, Tang D, Gao P, Lu Z, Liu J, Xia L, Yang J, Hao Z, Zhou J, and Zhang X.
