The effort to determine the global burden of premature ejaculation (PE) has been impeded by the lack of a clear and universally accepted definition of the condition. Current diagnostic criteria are variable and rely, to a large degree, on subjective measurements. Moreover, the absence of a clear consensus on what constitutes a normal ejaculatory latency has impeded research into the prevalence of PE, although evidence is gradually accruing that may make this definition easier. Perception of "normal" ejaculatory latency varies by country and can differ when assessed either by the patient or their partner. Despite these limitations, information from the Global Study of Sexual Attitudes and Behaviors and other sources suggests a global prevalence of PE of approximately 30% across all age groups. The etiology underpinning this prevalence remains to be clarified, but current evidence reflects a shift from psychogenic theories to more neurobiological bases. While elucidation of the etiology of PE will undoubtedly aid the development of more effective therapies, it is clear that, whatever the cause of the condition, it is associated with a significant burden on psychological and overall health.
由于缺乏对早泄（PE）这一病症清晰且被普遍接受的定义，确定早泄全球负担的努力受到了阻碍。当前的诊断标准各不相同，且在很大程度上依赖主观测量。此外，对于何为正常射精潜伏期缺乏明确的共识，这阻碍了对早泄患病率的研究，不过逐渐有证据出现，可能会使这一定义变得更容易确定。对“正常”射精潜伏期的认知因国家而异，并且由患者或其伴侣进行评估时也可能不同。尽管存在这些局限性，但来自《全球性态度和行为研究》及其他来源的信息表明，所有年龄组的早泄全球患病率约为30%。导致这一患病率的病因仍有待阐明，但目前的证据反映出从心理成因理论向更多神经生物学基础的转变。虽然阐明早泄的病因无疑将有助于开发更有效的治疗方法，但很明显，无论该病症的病因是什么，它都与心理和整体健康的重大负担相关。
