Abstract：
To determine whether men with lifelong vs acquired premature ejaculation (PE) subtypes differ on their estimated ejaculation latencies (EL) and related sexual, relationship, and behavioral parameters.
Of 2679 men who responded to an online multinational survey about sexual health and met inclusion criteria, 540 reported \"probable\" or \"definite\" PE, as assessed by the Premature Ejaculation Diagnostic Tool. Lifelong and acquired PE subtypes were compared on multiple measures related to EL, as well as on sets of demographic, diagnostic, relationship, sexual behavioral, and sexual functioning measures during both partnered sex and masturbation.
Nearly 73% of men with PE in this sample reported the lifelong subtype. No differences emerged in EL measures between subtypes, even when parsed according to age. Specifically, men 37years or under with either definite lifelong or acquired PE reported ELs of 1.9 minutes (SD=1.3). For men over 37, lifelong ELs were 2.0 minutes (SD=1.3), acquired ELs 2.4 minutes (SD=1.4). While the lifelong subgroup was younger and reported lower erectile functioning, these differences occurred only in the probable PE group and not the definite PE group.
Our data do not support different EL criteria for men with acquired vs lifelong PE, as suggested by several professional definitions. Furthermore, differences in age and erectile functioning between the groups, often reported in clinical samples though not in our definite PE group, may be an artifact of the general health/patient characteristics that lead such men to seek medical assistance.

摘要：
目的：确定终生早泄（PE）亚型与获得性早泄（PE）亚型的男性在估计射精潜伏期（EL）和相关性方面是否存在差异，关系,和行为参数。
方法：在对一项关于性健康的跨国在线调查做出回应并符合纳入标准的2679名男性中，540报告“可能”或“确定”PE，由早泄诊断工具评估。终身和获得性PE亚型在与EL相关的多个指标上进行比较，以及人口统计，诊断,关系,性行为,以及伴侣性行为和手淫期间的性功能措施。
结果：在这个样本中，近73%的男性PE报告了终身亚型。亚型之间的EL测量没有差异，即使根据年龄进行分析。具体来说,37岁或以下有明确终身或获得性PE的男性报告ELs为1.9分钟(SD=1.3)。对于37岁以上的男性，终身ELs为2.0分钟（SD=1.3），获得ELs2.4分钟（SD=1.4）。虽然终身亚组较年轻，并且报告勃起功能较低，这些差异仅发生在可能的PE组而非明确的PE组.
结论：我们的数据不支持获得性PE与终身PE的男性不同的EL标准，正如几个专业定义所建议的那样。此外，组间年龄和勃起功能的差异，经常在临床样本中报告，尽管不是在我们明确的PE组中，可能是导致此类男性寻求医疗救助的一般健康/患者特征的产物。
