The ejaculation latency (ELT) criterion for men with premature ejaculation (PE), including its 2 major subtypes of lifelong and acquired, relies heavily on expert opinion, yet such information represents only one source of data for this determination; furthermore, information regarding ELTs for PE within specific subgroups of men (eg, gay, bisexual) has been lacking.
To obtain data regarding men's lived experiences and expectations regarding typical ejaculation, ideal ejaculation, and PE and (for men) self-reported ejaculatory latencies during partnered sex across a variety a groups, including men vs women (ie, sexual partners of men), men with and without PE, and straight vs gay/bisexual men.
We recruited 1,065 men and sexual partners of men, asking them to estimate typical ejaculation, ideal ejaculation, and PE and (for men) self-latencies through an online survey posted on social media. Demographics, sexual identity, and sexual response data were also collected.
Typical and self-reported ELTs were closely aligned with those reported in the literature, with ideal ELTs generally longer than typical ELTs. Median PE ELTs were consistently estimated around 1.5 min, with nearly all subgroups-men vs women; straight vs gay; PE and non-PE men-showing alignment on this criterion. Men with lifelong PE did not differ from men with acquired PE in either their PE ELT estimation or their self-reported ELT.
The data support the idea of extending the latency cutoff for establishing a PE diagnosis beyond the current 1-minute threshold.
STRENGTHS & LIMITATIONS: A large sample size drawn from a multinational population powered the study, whereas the use of social media for recruitment and lack of inclusion of lesbian and asexual individuals may have missed relevant data from some who have had sexual experience with men.
Straight and nonstraight men do not differ in their ELT estimations. In addition, the use of different ELT criteria for lifelong vs acquired PE may be unnecessary. Côté-Léger P, Rowland DL.

早泄（PE）男性的射精潜伏期（ELT）标准，包括其两种主要亚型：终身和获得性，严重依赖于专家意见，但此类信息仅代表此类确定的一种数据源；此外，关于特定男性亚组（例如男同性恋、双性恋）的 PE 的 ELT 信息一直缺乏。
获取有关男性在各种群体中对典型射精、理想射精、PE 以及（男性）在伴侣性活动中报告的射精潜伏期的真实体验和预期的数据，包括男性与女性（即男性性伴侣）、有和无 PE 的男性以及异性恋和男同性恋/双性恋男性。
我们招募了 1065 名男性和男性性伴侣，要求他们通过社交媒体上发布的在线调查来估计典型射精、理想射精、PE 以及（男性）的自我潜伏期。还收集了人口统计学、性身份和性反应数据。
典型和自我报告的 ELT 与文献中报告的 ELT 非常吻合，理想 ELT 通常比典型 ELT 长。中位数 PE 的 ELT 一直估计在 1.5 分钟左右，几乎所有亚组——男性与女性；异性恋与男同性恋；PE 和非 PE 男性——都在这个标准上一致。在 PE ELT 估计或自我报告的 ELT 方面，终身 PE 男性与获得性 PE 男性没有差异。
这些数据支持将确定 PE 诊断的潜伏期截止值扩展到当前 1 分钟阈值以上的想法。
从多国人口中抽取的大样本量为该研究提供了动力，而使用社交媒体进行招募以及未纳入女同性恋和无性恋者可能会错过一些有过与男性发生性行为的人的相关数据。
异性恋和非异性恋男性在 ELT 估计上没有差异。此外，对于终身性和获得性 PE 使用不同的 ELT 标准可能是不必要的。
