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."
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.
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."
In addition to medical and sexual history, self-estimated intravaginal ejaculatory latency times (IELTs) of patients were used in the classification of patients.
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 IELT for all subjects was 65.16 +/- 83.75 seconds (2-420 seconds). Patients with lifelong PE had significantly lower mean self-reported IELT, whereas the patients with premature-like ejaculatory dysfunction had the highest mean IELT (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); and (iv) premature-like ejaculatory dysfunction: 286.67 +/- 69.96 seconds (180-420 seconds).
The majority of patients who seek treatment for the complaint of ejaculating prematurely describes lifelong PE. Further population-based studies are required to determine the actual prevalences of these four PE syndromes.
除了“终身”和“获得性”早泄（PE）综合征外，最近又提出了另外两种 PE 综合征：“自然变量 PE”和“类似早泄的性功能障碍”。
本研究旨在分析因早泄主诉而就诊于泌尿科门诊的患者中四种 PE 综合征的患病率。
2008 年 7 月至 2009 年 3 月，因早泄主诉就诊于泌尿科门诊的患者被纳入研究。在仔细询问病史和性生活史后，将患者分为“终身”、“获得性”、“自然变量”PE 或“类似早泄的性功能障碍”。
除病史和性生活史外，患者的自我估计阴道内射精潜伏期时间（IELT）也用于患者的分类。
共招募了 261 名平均年龄 36.39±10.45 岁（范围 20-70 岁）的有生育能力的男性。大多数男性被诊断为终身 PE（62.5%）；其余男性被诊断为获得性 PE（16.1%）、自然变量 PE（14.5%）或类似早泄的性功能障碍（6.9%）。获得性 PE 患者的平均年龄明显高于其他组（P=0.001）。不同 PE 组患者的教育程度或收入水平无显著差异（P=0.983 和 P=0.151）。所有受试者的平均自我估计 IELT 为 65.16±83.75 秒（2-420 秒）。终身 PE 患者的平均自我报告 IELT 明显较低，而类似早泄的性功能障碍患者的平均 IELT 最高（P=0.001）：（i）终身 PE：20.47±28.90 秒（2-120 秒）；（ii）获得性 PE：57.91±38.72 秒（90-180 秒）；（iii）自然变量 PE：144.17±22.47 秒（120-180 秒）；（iv）类似早泄的性功能障碍：286.67±69.96 秒（180-420 秒）。
因早泄主诉而就诊的患者中，大多数为终身 PE。需要进一步进行基于人群的研究以确定这四种 PE 综合征的实际患病率。
