Although the normal intravaginal ejaculation latency time (NIELT) as subjectively perceived by patients with premature ejaculation (PE) and expected IELT (EIELT), which represents the individual's expectations of what treatment for PE would achieve, are critically influential in the treatment of patients with PE, there is a significant dearth of exploratory research on NIELT and EIELT among patients with PE.
To explore the NIELT and EIELT of patients with PE, understand why patients with PE perceive such a long IELT as normal, and identify factors associated with EIELT.
We recruited both patients with PE and control subjects, and analyzed the parameters related to IELT using detailed interviews and questionnaires.
Parameters related to IELT.
A total of 592 individuals (mean age 29.6 ± 6.2) were included in the study, comprising 466 patients with PE (mean age 28.3 ± 5.4) and 126 non-PE individuals (mean age 34.6 ± 6.5). The actual perceived intravaginal ejaculation latency time (PIELT), referring to the patient's self-assessed IELT at baseline, as well as NIELT, and EIELT of patients with PE, were 1.0 (1.0 - 2.0), 14.0 (10.0 - 15.0), and 15.0 (10.0 - 20.0), respectively. The control group's PIELT and EIELT were 15.0 (10.0 - 20.0) and 20.0 (15.0 - 24.3), respectively, showing statistical differences compared with the PIELT and EIELT in the PE group. In the PE group and the control group, 31.5% and 57.9% of individuals, respectively, have an EIELT greater than the average actual normal ejaculatory latency time of 15.0 minutes. Among patients with PE, 51.3% expressed a NIELT >10 minutes, identical to the EIELT in a higher percentage (59.4%). The control group's EIELT is 5 minutes longer than the PE group's EIELT. Multivariable linear regression analysis showed that age, marital status, education level, BMI, satisfaction evaluation of PIELT, PEDT score, and IIEF-6 score were not associated with EIELT; only NIELT (beta = 0.817, P < 0.001) and PIELT (beta = 0.056, P = 0.044) were related to EIELT.
Sexual health care providers should be aware that patients with PE have excessively high expectations for IELT.
The first study explores why patients with clinically diagnosed PE perceive long IELT as normal and examines factors associated with EIELT. Further validation is needed in different cultural contexts.
Patients with PE often have excessively high expectations regarding IELT, primarily due to their insufficient understanding of IELT.
尽管早泄（PE）患者主观感知的正常阴道内射精潜伏期（NIELT）以及预期射精潜伏期（EIELT，代表个体对PE治疗效果的期望）在PE患者的治疗中具有关键影响，但目前关于PE患者的NIELT和EIELT的探索性研究严重匮乏。
探讨PE患者的NIELT和EIELT，了解PE患者为何将如此长的射精潜伏期视为正常，并确定与EIELT相关的因素。
我们招募了PE患者和对照受试者，并通过详细访谈和问卷调查分析与射精潜伏期相关的参数。
与射精潜伏期相关的参数。
本研究共纳入592名个体（平均年龄29.6±6.2岁），其中包括466例PE患者（平均年龄28.3±5.4岁）和126例非PE个体（平均年龄34.6±6.5岁）。PE患者在基线时自我评估的实际阴道内射精潜伏期（PIELT）、NIELT和EIELT分别为1.0（1.0 - 2.0）、14.0（10.0 - 15.0）和15.0（10.0 - 20.0）。对照组的PIELT和EIELT分别为15.0（10.0 - 20.0）和20.0（15.0 - 24.3），与PE组的PIELT和EIELT相比有统计学差异。在PE组和对照组中，分别有31.5%和57.9%的个体EIELT大于平均实际正常射精潜伏期15.0分钟。在PE患者中，51.3%表示NIELT>10分钟，与EIELT相同的比例更高（59.4%）。对照组的EIELT比PE组的EIELT长5分钟。多变量线性回归分析显示，年龄、婚姻状况、教育水平、BMI、对PIELT的满意度评价、PEDT评分和IIEF - 6评分与EIELT无关；仅NIELT（β = 0.817，P < 0.001）和PIELT（β = 0.056，P = 0.044）与EIELT相关。
性健康护理提供者应意识到PE患者对射精潜伏期的期望过高。
第一项研究探讨了临床诊断为PE的患者为何将长射精潜伏期视为正常，并研究了与EIELT相关的因素。需要在不同文化背景下进行进一步验证。
PE患者对射精潜伏期的期望往往过高，主要是因为他们对射精潜伏期的了解不足。
