Common Causes of Premature Ejaculation in Men
一、早泄的定义与普遍性 | Understanding PE Prevalence
早泄（Premature Ejaculation, PE）是男性最常见的性功能障碍之一，全球约20%-30%男性受其困扰。根据国际性医学协会（ISSM）定义，早泄表现为射精时间过短、缺乏控制感，并对心理或亲密关系造成负面影响。
Premature Ejaculation (PE) affects 20%-30% of men globally. The ISSM defines PE as consistently ejaculating within 1 minute of penetration (primary PE) or earlier than desired, accompanied by a sense of lost control and emotional distress.
二、生理性原因 | Physical Causes
1. 神经敏感度过高 | Hypersensitive Nerve Pathways
阴茎头部或神经末梢过度敏感可能直接触发快速射精反射，尤其是未割包皮的男性。
Overactive penile nerves: High sensitivity in the glans or foreskin may accelerate ejaculation, particularly in uncircumcised men.
2. 激素失衡 | Hormonal Imbalances
- 甲状腺功能异常：甲状腺激素过高或过低可能干扰射精调控机制。
Thyroid disorders: Hyperthyroidism or hypothyroidism disrupts neurological control. - 睾酮水平波动：低睾酮可能降低性欲，间接导致早泄。
Low testosterone: Reduced libido may affect arousal management.
3. 慢性疾病影响 | Chronic Health Conditions
糖尿病、心血管疾病或前列腺炎可能损害神经或血管功能，影响射精控制。
Diabetes, heart disease, or prostatitis: These conditions impair blood flow or nerve signaling, worsening PE.
三、心理性原因 | Psychological Triggers
1. 性焦虑与压力 | Performance Anxiety
对性表现的过度担忧（如害怕伴侣失望）可能形成恶性循环，导致更快射精。
Fear of underperforming: Anxiety about satisfying a partner can trigger a self-fulfilling prophecy.
2. 抑郁与情绪障碍 | Depression and Mood Disorders
长期抑郁可能降低血清素水平（一种调节射精的神经递质），削弱控制能力。
Low serotonin levels: Depression reduces this key neurotransmitter’s ability to delay ejaculation.
3. 性经验不足 | Lack of Sexual Experience
年轻男性或性行为频率低的人群可能因不熟悉身体反应而难以延迟射精。
Inexperience: Difficulty recognizing arousal cues may lead to rapid climax.
四、不良生活习惯 | Unhealthy Lifestyle Choices
1. 吸烟与酗酒 | Smoking and Alcohol Abuse
- 吸烟：尼古丁收缩血管，降低阴茎血流量，影响控制力。
Smoking: Nicotine constricts blood vessels, reducing penile sensitivity regulation. - 酗酒：短期放松作用后，长期饮酒会损害神经系统功能。
Alcohol: Chronic use damages nerve pathways critical for ejaculatory control.
2. 久坐与缺乏运动 | Sedentary Lifestyle
久坐削弱骨盆底肌肉力量，而规律的凯格尔运动可增强射精控制力。
Weak pelvic muscles: Inactivity reduces muscle strength; Kegel exercises can counteract this.
3. 快速自慰习惯 | Habitual Quick Masturbation
长期以追求快速高潮为目的的自慰可能训练大脑形成“速射”模式。
“Rush-to-finish” masturbation: Conditions the body to ejaculate prematurely during intercourse.
五、伴侣关系与社会因素 | Relationship and Social Influences
1. 沟通不良与情感冲突 | Poor Communication
伴侣间对性需求或期望的误解可能加剧焦虑，形成压力循环。
Unspoken expectations: Lack of dialogue increases stress during intimacy.
2. 文化羞耻感 | Cultural Stigma
在亚洲保守文化中，男性可能因羞于讨论性健康而延误就医。
Stigma in Asian communities: Cultural taboos discourage men from seeking timely help.
3. 工作压力 | Workplace Stress
新加坡快节奏、高压的工作环境可能导致慢性压力，扰乱性功能。
Singapore’s high-pressure culture: Prolonged stress elevates cortisol, impairing sexual performance.
六、如何应对？ | What Can You Do?
- 自我评估：记录射精时间、情绪状态与触发场景，识别主因。
Track patterns: Note timing, stress levels, and context to identify triggers. - 渐进调整：从戒除烟酒、加强运动开始，逐步改善生活习惯。
Small lifestyle changes: Quit smoking, exercise regularly, and practice pelvic floor exercises. - 专业支持：新加坡的泌尿科医生（如莱佛士医院）或性治疗师可提供定制化方案。
Consult experts: Visit urologists at Raffles Hospital or certified therapists for personalised care.
总结 | Key Takeaway
早泄并非单一因素所致，往往是生理、心理与生活方式共同作用的结果。新加坡男性应正视问题，结合科学调整与专业支持，逐步恢复自信与掌控力。
PE is rarely caused by a single factor. Singaporean men are encouraged to address it holistically through lifestyle changes, open communication, and expert guidance.
