摘要
背景：尽管早泄（PE）患者主观认为的正常阴道内射精潜伏时间（NIELT）和预期阴道内射精潜伏时间（EIELT）对PE患者的治疗具有重要影响，但有关PE患者阴道内射精潜伏时间和预期阴道内射精潜伏时间的探索性研究却非常缺乏。目的：探讨 PE 患者的 NIELT 和 EIELT，了解为什么 PE 患者认为如此长的 IELT 是正常的，并确定与 EIELT 相关的因素：我们招募了 PE 患者和对照组受试者，并通过详细的访谈和问卷调查分析了 IELT 的相关参数：结果：与 IELT 相关的参数：研究共纳入 592 人（平均年龄为 29.6 ± 6.2），其中包括 466 名 PE 患者（平均年龄为 28.3 ± 5.4）和 126 名非 PE 患者（平均年龄为 34.6 ± 6.5）。PE患者的实际阴道内射精潜伏时间（PIELT）（指基线时患者自我评估的IELT）、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 相比存在统计学差异。在 PE 组和对照组中，分别有 31.5% 和 57.9% 的人的 EIELT 超过平均实际正常射精潜伏时间 15.0 分钟。在 PE 患者中，51.3% 的患者的 NIELT >10 分钟，与 EIELT 相同的患者比例更高（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表明，年龄、婚姻状况、教育程度、体重指数、PIELT满意度评估、PEDT评分和IIEF-6评分与EIELT无关；只有NIELT（β=0.817，P 临床意义：性健康保健提供者应意识到，PE 患者对 IELT 的期望值过高：第一项研究探讨了临床诊断为 PE 的患者为何认为长时间的 IELT 是正常的，并研究了与 EIELT 相关的因素。需要在不同的文化背景下进一步验证：结论：PE 患者往往对 IELT 抱有过高的期望，这主要是由于他们对 IELT 的理解不足。
Perception of normal and treatment level ejaculatory latency times in men with premature ejaculation.
Background: 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.
Aim: 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.
Methods: We recruited both patients with PE and control subjects, and analyzed the parameters related to IELT using detailed interviews and questionnaires.
Outcomes: Parameters related to IELT.
Results: 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.
Clinical implications: Sexual health care providers should be aware that patients with PE have excessively high expectations for IELT.
Strengths and limitation: 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.
Conclusion: Patients with PE often have excessively high expectations regarding IELT, primarily due to their insufficient understanding of IELT.
期刊介绍：
The Journal of Sexual Medicine publishes multidisciplinary basic science and clinical research to define and understand the scientific basis of male, female, and couples sexual function and dysfunction. As an official journal of the International Society for Sexual Medicine and the International Society for the Study of Women''s Sexual Health, it provides healthcare professionals in sexual medicine with essential educational content and promotes the exchange of scientific information generated from experimental and clinical research.
The Journal of Sexual Medicine includes basic science and clinical research studies in the psychologic and biologic aspects of male, female, and couples sexual function and dysfunction, and highlights new observations and research, results with innovative treatments and all other topics relevant to clinical sexual medicine.
The objective of The Journal of Sexual Medicine is to serve as an interdisciplinary forum to integrate the exchange among disciplines concerned with the whole field of human sexuality. The journal accomplishes this objective by publishing original articles, as well as other scientific and educational documents that support the mission of the International Society for Sexual Medicine.
