Abstract
Because available definitions of premature ejaculation (PE) were unable to encompass the various forms of PE, Waldinger et al. proposed a new classification that distinguished four PE syndromes. However, few studies have examined the prevalence rates of these four PE syndromes. The study aims to analyze the prevalence of and factors associated with four PE syndromes in outpatients who complained of ejaculating prematurely. Between December 2009 and December 2011, outpatients who complained of PE completed a detailed verbal questionnaire regarding their demographic data and medical and sexual history. Each patient was classified as having one of four PE subtypes: lifelong PE (LPE), acquired PE (APE), natural variable PE (NVPE), or premature-like ejaculatory dysfunction (PLED). Based on the new classification scheme, PE was classified into four subtypes. The anxiety/depression status of patients was assessed by the Zung self-rating anxiety/depression scales, and erectile function was assessed by the International Index of Erectile Function-5 instrument.
