The DSM-IV diagnostic criteria for premature ejaculation remain to be investigated by a clinical study. A prospective study was therefore conducted to investigate the DSM-IV definition and to provide an empirical operationalization of premature ejaculation. In this study 140 men suffering from lifelong premature ejaculation were interviewed separately from their partners. Various means of assessing the intravaginal ejaculation latency time (IELT) were compared: assessment by spontaneous answer, by questionnaire, by imagining foreplay and intercourse and estimating the ejaculation time without a clock or with a clock, and by stop-watch measurement at home over a one-month period. The number of thrusts and feelings of control during foreplay and intercourse were also assessed. A total of 110 men used the stop-watch method. Ninety percent of all the subjects ejaculated within one minute of intromission, with 80% actually ejaculating within 30 seconds. The age of the men and duration of their relationship were not correlated with IELT; however, the IELT tended to be longer for couples who had a higher frequency of intercourse. There was only a moderate correlation between the various methods of assessing IELT. The results suggest that premature ejaculation could be operationally defined as an IELT < 1 min in more than 90% of episodes of sexual intercourse, independent of age and duration of relationship.
DSM-IV 对早泄的诊断标准仍需通过临床研究进行调查。因此，进行了一项前瞻性研究，以调查 DSM-IV 定义，并对早泄进行实证操作化。在这项研究中，140 名患有终身早泄的男性与其伴侣分别接受了访谈。比较了评估阴道内射精潜伏期时间（IELT）的各种方法：自发回答、问卷调查、想象前戏和性交以及在没有时钟或有时钟的情况下估计射精时间，以及在家中使用秒表在一个月内进行测量。还评估了前戏和性交期间的冲刺次数和控制感。共有 110 名男性使用秒表法。所有受试者中有 90%在插入后一分钟内射精，80%实际上在 30 秒内射精。男性的年龄和关系持续时间与 IELT 无关；然而，对于性交频率较高的夫妇，IELT 往往更长。评估 IELT 的各种方法之间只有中度相关性。研究结果表明，早泄可以操作定义为 90%以上的性交过程中 IELT<1 分钟，与年龄和关系持续时间无关。
