Although premature ejaculation (PE) is a common type of male sexual dysfunction, to date we lack a unified definition of PE. The multidimensional definition of PE has been accepted by more and more clinicians. Intravaginal ejaculatory latency time (IELT) is one of the three important dimensions (time to ejaculation, inability to control or delay ejaculation, and negative consequences) for defining PE. Rapid ejaculation is one of the core symptoms of PE and IELT is an objective measurement as well as an important tool for the evaluation of PE. This article reviews estimated IELT, stopwatch-measured IELT, the correlation between estimated and stopwatch-measured IELT, and the factors affecting IELT in the general male population, PE patients, and those complaining of PE.
尽管早泄（PE）是男性性功能障碍的一种常见类型，但迄今为止，我们仍缺乏对早泄的统一界定。早泄的多维定义已被越来越多的临床医生所接受。阴道内射精潜伏期（IELT）是定义早泄的三个重要维度（射精时间、无法控制或延迟射精以及负面后果）之一。快速射精是早泄的核心症状之一，而IELT是一种客观测量方法，也是评估早泄的重要工具。本文综述了一般男性人群、早泄患者以及主诉早泄者的IELT估计值、秒表测量的IELT、IELT估计值与秒表测量值之间的相关性以及影响IELT的因素。
