The Distribution of Patients Who Seek Treatment for the Complaint of Ejaculating Prematurely According to the Four Premature Ejaculation Syndromes

摘要

Introduction. In addition to "lifelong" and "acquired" premature ejaculation (PE) syndromes, two more PE syndromes have recently been proposed: "Natural variable PE" and "premature-like ejaculatory dysfunction." Aim. The purpose of this study was to analyze the prevalence of the four PE syndromes among patients who were admitted to a urology outpatient clinic with the complaint of ejaculating prematurely. Methods. Between July 2008 and March 2009, patients admitted to a urology outpatient clinic with a self-reported complaint of PE were enrolled into the study. After taking a careful medical and sexual history, patients were classified as "lifelong," "acquired," "natural variable," PE or "premature-like ejaculatory dysfunction." Main Outcome Measures. In addition to medical and sexual history, self-estimated intravaginal ejaculatory latency times (lELTs) of patients were used in the classification of patients. Results. A total of 261 potent men with a mean age of 36.39 +- 10.45 years (range 20-70) were recruited into the study. The majority of the men was diagnosed as having lifelong PE (62.5%); the remaining men were diagnosed as having acquired (16.1%), natural variable PE (14.5%), or premature-like ejaculatory disorder (6.9%). The mean age of patients with acquired PE was significantly higher than the other groups {P = 0.001). No significant difference was observed for educational status or income level of patients in the different PE groups (P= 0.983 and P= 0.151, respectively). The mean self-estimated lELT for all subjects was 65.16 +- 83.75 seconds (2-420 seconds). Patients with lifelong PE had significantly lower mean self-reported lELT, whereas the patients with premature-like ejaculatory dysfimction had the highest mean lELT (P= 0.001): (i) life-long PE: 20.47 +- 28.90 seconds (2-120 seconds); (ii) aquired PE: 57.91 +- 38.72 seconds (90-180 seconds); (iii) natural variable PE: 144.17 +- 22.47 seconds (120-180 seconds);(iv) premature-Uke ejaculatory dysfunction: 286.67 +- 69.96 seconds (180-420 seconds). Conclusions. The majority of patients who seek treatment for the complaint of ejaculating prematurely describes lifelong PE. Eurther population-based studies are required to determine the actual prevalences of these four PE syndromes.
