Prevalence and Associated Factors of Premature Ejaculation in the Anhui Male Population in China: Evidence-Based Unified Definition of Lifelong and Acquired Premature Ejaculation

Abstract

IntroductionIn 2014, new evidence-based definitions of lifelong premature ejaculation (LPE) and acquired premature ejaculation (APE) were proposed by the International Society for Sexual Medicine. Based on the new PE definitions, the prevalence of and factors associated with LPE and APE have not been investigated in China.AimTo evaluate the prevalence of and factors associated with LPE and APE in men with the complaint of PE in China.MethodsFrom December 2011 to December 2015, a cross-sectional field survey was conducted in five cities in the Anhui province of China. Questionnaire data of 3,579 men were collected in our database. The questionnaire included subjects' demographic information and medical and sexual histories. Men who were not satisfied with their time to ejaculate were accepted as having the complaint of PE. Men with the complaint of PE who met the new definition of PE were diagnosed as having LPE or APE.Main Outcome MeasuresNew definition of LPE and APE.ResultsOf 3,579 men who completed the questionnaire, 34.62% complained of PE. Mean age, body mass index, and self-estimated intravaginal ejaculatory latency time for all subjects were 34.97 ± 9.02 years, 23.33 ± 3.56 kg/m2, and 3.09 ± 1.36 minutes, respectively. The prevalences of LPE and APE in men with the complaint of PE were 10.98% and 21.39%, respectively. LPE and APE were associated with age, body mass index, and smoking and exercise rates (P < .001 for all comparisons). Men with APE reported more comorbidities than men with LPE, especially in the presence of hypertension, diabetes mellitus, and heart disease (P < .001 for all comparisons).ConclusionIn this study, the prevalences of LPE and APE in men with the complaint of PE were 10.98% and 21.39%, respectively. Patients with APE were older and more likely to smoke, had more comorbidities, and had a higher body mass index than patients with LPE.

Clinical characteristics of men complaining of premature ejaculation together with erectile dysfunction: a cross‐sectional study

“…When compared with PE‐only patients, those with ED and PE have a higher prevalence of hypertension, diabetes, and heart diseases, more organic risk factors for sexual dysfunction (as denoted by a higher SIEDY scale 1 score), worse penile blood flows and, accordingly, a greater estimated 10‐year CV risk. This suggests that ED‐PE men should be regarded as patients at higher CV risk and not considered similar to PE‐only men, who are not usually characterized by cardio‐metabolic risk factors (Corona et al ., ; Lotti et al ., ; Gao et al ., ). Hence, in PE patients, clinicians should carefully investigate the concomitant presence of ED not only for choosing the most proper treatment, but also for identifying overall unhealthier subjects.…”

Penile sensory thresholds in subtypes of premature ejaculation: implications of comorbid erectile dysfunction

“…This phenomenon may be due to the higher percentage of APE in the IELT >1 min group because a previous study reported that patients with APE were more likely to smoke. 29 In normal men, no correlation between the penile vibratory threshold and IELT was found, and penile sensitivity cannot explain variability in IELT. 30 We validated this conclusion in the PE population by finding no difference in the penile sensory thresholds between the IELT ≤1 min and IELT >1 min groups, and there was no correlation between penile sensitivity and IELT.…”

Surgical treatment for primary premature ejaculation with an inner condom technique

“…Premature ejaculation is one of the common male sexual problems, with the reported prevalence rate of 20% to 30% in China. [1] Subjects with premature ejaculation would have short intravaginal ejaculatory latency time (IELT) of less than 1 min. Personal distress and interpersonal difficulty were often experienced along with ejaculatory dysfunction.…”
