Over the past decade, professional organizations and consensus groups have offered a variety of definitions for premature ejaculation (PE), all generally including a set of common concepts but all varying in specific language and operationalization. Clearly articulated definitions of such conditions are important because they not only affect prevalence rates but also diagnostic inclusion-who is deemed to have the condition and therefore who might be eligible for treatment.
The current study had two goals: (i) to examine the effects on prevalence rates of moving the cutoff points from more stringent to less stringent for each of three PE criteria-ejaculatory latency, distress, and ejaculating before desired; and (ii) to explore in detail the relationships among the three criteria.
Using an Internet-based sample of 1,183 men, we examined the responses of 374 with PE-type symptoms based on consensus definitions, and determined the effect of decreasing restrictions on the cutoff criteria. In addition, we calculated both correlations and concordance rates among criteria.
Numeric and graphic depiction of the effects of moving the cutoff point for each of the three criteria is provided in the URL "PE Prevalence," a dynamic tool developed specifically for this study (https://sites.google.com/a/valpo.edu/PEprevalence/). In addition, statistical relationships among the PE criteria suggest sufficient independence to warrant inclusion of all three in a diagnostic procedure as well as to consider a 2-minute ejaculatory latency as the threshold for a PE diagnosis.
Based on our data, clinicians should approach the 1-minute ejaculatory latency time (ELT) criterion with flexibility, considering ELTs up to 2 minutes for a PE diagnosis. At the same time, frequency of occurrence of either ejaculating before desired or of distress about the condition, as long as they reach at least 50% of the time, had only minor impact on PE diagnostic inclusion.
在过去的十年中，专业组织和共识小组为早泄（PE）提供了多种定义，所有这些定义通常都包括一组共同的概念，但在具体语言和操作化方面存在差异。这些条件的明确定义很重要，因为它们不仅影响流行率，而且还影响诊断纳入标准-谁被认为患有该疾病，因此谁可能有资格接受治疗。
本研究有两个目标：（i）检查将三种 PE 标准（射精潜伏期、苦恼和渴望前射精）的截止点从更严格变为不那么严格时对流行率的影响；（ii）详细探讨这三个标准之间的关系。
我们使用基于互联网的 1183 名男性样本，检查了 374 名根据共识定义出现 PE 症状的男性的反应，并确定了降低截止标准限制的效果。此外，我们还计算了标准之间的相关性和一致性。
在 URL“PE 流行率”中提供了将三个标准中的每个标准的截止点移动的效果的数字和图形表示，这是专门为此研究开发的动态工具（https://sites.google.com/a/valpo.edu/PEprevalence/）。此外，PE 标准之间的统计关系表明它们具有足够的独立性，足以保证将所有三个标准纳入诊断程序，并考虑 2 分钟的射精潜伏期作为 PE 诊断的阈值。
根据我们的数据，临床医生应该灵活地对待 1 分钟射精潜伏期（ELT）标准，考虑将 ELT 延长至 2 分钟以诊断 PE。同时，只要达到至少 50%的时间，渴望前射精或对这种情况的苦恼的发生频率对 PE 诊断的纳入只有较小的影响。
