早泄：正确评估，按规律治疗。

早泄（PE）在性活动中持续地比预期更早达到高潮，给伴侣一方或双方带来痛苦。 AUA/SMSNA 指南使用两个标准定义终身（主要）PE：插入式性交开始后约 2 分钟内射精，以及感觉无法延迟射精。⁵

早泄是男性最常见的性健康问题。大约三分之一的男性在生命中某个阶段经历过早泄，约20-30%的人长期受此困扰。¹ 尽管这种情况很普遍，但只有一小部分人寻求治疗——部分原因是尴尬，部分原因是许多人没有意识到有效的治疗方法存在。

早泄（PE）分为四种类型： 终身（主要） PE，从第一次性经历开始， 获得的（次要的） PE，在正常控制一段时间后发生， 变异型 PE（在其他功能正常的男性中不规则发生），以及 主观型 PE（射精时间客观正常的男性所感知的 PE）。类型很重要，因为治疗方法不同。

管理变革最大的区别是主要与次要。 原发性（终身）PE 自从男性性行为活跃以来，这种情况就一直存在，并且更多地是由生物驱动的，因此治疗主要针对射精控制本身：行为技术、局部麻醉剂和按需达泊西汀。 继发性（获得性）PE 代表以前正常控制的变化，通常有可识别的医学或心理原因。对于继发性肺栓塞，第一步是找到并治疗病因。⁵

早泄（PE）是可以有效治疗的。大多数患者在接受循证治疗后会有显著改善，特别是当行为疗法与药物治疗相结合时。

早泄既有生理因素也有心理因素，大多数病例是两者共同作用的结果。了解主导因素有助于制定治疗方案。

血清素差异 是终身（原发性）PE 的最强生物学因素。特定大脑区域的血清素信号降低会降低射精的阈值。这就是为什么 选择性血清素再摄取抑制剂（SSRIs） 例如按需使用的达泊西汀（dapoxetine）可提高血清素信号，用于治疗 PE。

阴茎敏感度 可能会导致终生（原发性）PE，因为增强的感觉反馈更容易触发射精。表面麻醉剂直接解决了这一机制。

焦虑与心理因素 是获得性（二级）PE 的最强贡献者。表现焦虑、人际关系压力、抑郁和生活压力都会降低射精控制。这种模式通常是“快速→焦虑→更快”——一种自我强化的循环，对行为和药物的联合治疗反应良好。

共存 勃起功能障碍 存在于获得性（继发性）PE 患者中相当大的比例。治疗 ED 通常可以改善 PE，而治疗其中一种而不治疗另一种可能会使另一种恶化。临床评估总是考虑两者。

激素因素 包括 睾酮缺乏 甲状腺功能障碍也可能导致这种情况。甲状腺功能亢进症尤其与 PE 相关，因此甲状腺功能应纳入评估（如有需要）。⁶

前列腺炎症（前列腺炎) 与某些患者获得性（继发性）PE 相关。如果盆腔不适或泌尿系统症状伴随 PE，前列腺评估是检查的一部分。

物质使用 including some recreational drugs and excessive alcohol can affect ejaculatory control. Withdrawal matters as much as use: stopping opioids, and occasionally stopping long-standing antidepressant treatment, can shorten latency. Medication review is part of every consultation.

Family history and anatomy. Lifelong PE shows familial clustering in several studies, which supports the neurobiological explanation rather than a behavioural one. In a minority of men a short or tight frenulum raises sensitivity enough to matter, which is why a brief genital examination is part of assessment.

一般健康因素 也很重要，所以 全面健康检查 是男性性健康检查的一部分，特别是针对 40 岁以上患者的获得性（继发性）早泄。

在您访问之前。 您的个人健康礼宾人员会分享一份简短的表格，内容包括症状史、早泄类型（原发性或继发性）、性史（包括伴侣情况）、当前服用的药物以及任何同时出现的问题。这种摄入有助于将咨询时间集中在评估而不是数据收集上。

在您访问期间。 咨询持续30-45分钟。我们的医疗团队会重点记录病史，包括症状模式、发病情况、情况变化、伴侣的观点（如果有帮助），以及筛查同时发生的病症（ED、焦虑、抑郁、前列腺症状）。体检很简短，通常仅限于一般评估，除非出现其他问题。

直接的原发性肺栓塞通常不需要进行调查。如果存在继发性 PE 或同时出现的问题，可能会增加血液检查（睾酮、甲状腺功能、催乳素、葡萄糖）。尿液分析是否有前列腺症状。

您访问后。 首次咨询时会讨论治疗方案，并通常立即开始初步治疗。后续随访安排在4周（评估反应）、12周（调整方案）以及根据需要进行长期随访。行为疗法将在随访中得到强化。

A formal diagnosis needs three things present together, not just a short time on the clock. Time: ejaculation consistently within about one minute of penetration for lifelong PE, or a clear reduction from a man's own previous latency, commonly to around three minutes or less, for acquired PE. Control: an inability to delay ejaculation on all or nearly all occasions. Consequence: distress, frustration or avoidance of intimacy.

The third criterion is the one most often forgotten and the one that matters most. A man who ejaculates in four minutes and is entirely content does not have a disorder. A man who ejaculates in three minutes and whose relationship is suffering has something worth treating. Distress is part of the diagnosis, not an optional extra.

Population studies that measured latency directly put the median at roughly five to six minutes, with a very wide spread, and the great majority of men falling between one and ten minutes. Two things follow. Many men who believe they are premature are inside the normal range and are comparing themselves against pornography, where duration is an editing decision. And the group who genuinely meet the one-minute criterion is smaller than the group who worry about it.

Self-reported PE runs at roughly twenty to thirty percent of adult men across surveys in Asia and internationally. Applying the strict one-minute criterion brings that figure down to the low single digits. That gap is clinically useful in itself: a meaningful share of men who come in are suffering from expectation rather than pathology, and an honest conversation serves them better than a prescription.

A significant proportion of men who present describing PE turn out to have something else, and separating them changes the treatment entirely.

Erectile dysfunction presenting as speed. A man who cannot reliably maintain an erection learns, often without recognising it, to hurry to ejaculation before the erection fades. The complaint is speed; the problem is rigidity. Treating the 勃起功能障碍 frequently resolves the ejaculatory pattern with no PE-specific treatment at all.

Normal variation misread as dysfunction. Some men who ask for treatment have latencies of five, seven or ten minutes and a belief, built on pornography and locker-room arithmetic, that this is inadequate. That is not premature ejaculation. It needs accurate information, and often a conversation with a partner whose expectations turn out to be different from what was assumed.

Variable and subjective patterns. Early ejaculation that happens inconsistently is normal variation. Believing you are premature despite a latency well inside the normal range is subjective PE. Neither is a disorder in the strict sense, though the distress is real and deserves to be addressed.

Men often arrive wanting to know which treatment is best. The more useful question is which pattern of use fits your situation, because the options differ less in effectiveness than in how they are lived with.

Everything in the medication rows above is prescription-only in Singapore and is dispensed after a consultation. Combination treatment consistently outperforms any single approach.

Treatment works best in a defined order, because the slow levers need to start early while the fast ones carry the first few weeks.

1. Assessment to separate lifelong from acquired PE and to screen for treatable causes.
2. Treat any identified cause, erectile difficulty above all.
3. Begin behavioural techniques and pelvic floor training, which take weeks to show.
4. Add a topical or on-demand oral option for immediate benefit while the training takes effect.
5. Review at four to six weeks and step up to daily treatment if on-demand is not enough.
6. Add psychological or couple support where anxiety or relationship strain persists.
7. Taper medication once behavioural gains are established, if you want to.

Skipping step two is the most common reason treatment underperforms.

Treatment fails as often through poor measurement as through poor choice of treatment, and two errors dominate.

The first is judging progress by a single encounter. Latency naturally varies with arousal, time since last ejaculation, alcohol, fatigue, novelty and stress. One disappointing occasion three weeks into a programme tells you nothing, and men who stop on that basis routinely discard something that was working.

The second is the stopwatch. Timing yourself turns sex into a performance under measurement, which raises exactly the anticipatory anxiety that shortens latency. A rough weekly impression across several occasions is more useful, together with two questions that matter more than the clock: how much control over the moment do you feel, and how much distress is this causing you and your partner. The validated tools used in clinic assess control and distress rather than seconds, for precisely this reason.

Expect a stepwise pattern rather than a smooth line: an early jump when a topical or oral option is introduced, a plateau, then slower and more durable improvement over six to twelve weeks as behavioural control and pelvic floor strength develop.

If eight to twelve weeks of a properly combined approach has produced little change, the explanations are usually specific rather than mysterious.

An untreated underlying cause is the most common: erectile difficulty that was never asked about, chronic 前列腺炎, or an untreated thyroid abnormality. Inconsistent technique is next, since behavioural methods need regular practice and few men do them as often as prescribed. Under-dosing or stopping oral treatment too early is third, because daily treatment needs one to two weeks before it can be judged. And in some cases the dominant driver is relationship conflict or a psychological factor that medication cannot reach, which is where couple-based therapy earns its place.

Reassessment works through each of these in turn before concluding that the condition is refractory. Genuinely treatment-resistant PE is uncommon.

Several widely repeated strategies do not hold up, and two of them carry real risk.

• Thick condoms and distraction. Occasionally helpful at the margins, unreliable as a strategy, and distraction tends to reduce enjoyment for both partners.
• Alcohol. Delays ejaculation at the cost of erectile quality and judgement, and builds a dependence on it for sex.
• Over-the-counter stamina supplements. No consistent evidence, and Singapore's Health Sciences Authority has repeatedly recalled such products for containing undeclared prescription ingredients. Products sold online promising instant results are unregulated and can be dangerous, particularly alongside heart medication.
• Surgery. Reserved for a small minority with a specific anatomical cause, not a general treatment.
