在探讨任何治疗方法之前，最重要的一步是咨询医生并获得明确诊断。 | Before exploring any treatment options, the most important step is to consult a doctor and obtain a clear diagnosis.
- 为什么？ ED可能是潜在健康问题（如心血管疾病、糖尿病、高血压或激素失衡）的征兆。医生（全科医生/GP或泌尿科医生/Urologist）需要通过问诊、体检和血液检查来确定根本原因。
- 去哪里？ 您可以前往新加坡的综合诊所（Polyclinic） 看全科医生，或直接预约私立/公立医院的泌尿科（Urology Department）。
- Why? ED can be a sign of underlying health issues (e.g., cardiovascular disease, diabetes, high blood pressure, or hormonal imbalances). A doctor (GP or Urologist) needs to determine the root cause through consultation, physical examination, and blood tests.
- Where to go? You can visit a Polyclinic to see a GP, or directly make an appointment with the Urology Department of a private/public hospital.
以下是经科学验证的主流医学治疗方法： | The following are mainstream, scientifically proven medical treatment methods:
一、口服药物治疗（一线选择）| 1. Oral Medications (First-Line Choice)
这是最常用、最方便且非侵入性的治疗方法。 | This is the most commonly used, convenient, and non-invasive treatment method.
- 磷酸二酯酶5抑制剂（PDE5抑制剂）| Phosphodiesterase Type 5 Inhibitors (PDE5 Inhibitors)
- 作用原理： 这类药物通过抑制PDE5酶，增加阴茎海绵体内的一种关键物质——环磷酸鸟苷（cGMP）的水平，从而促进血管平滑肌松弛，在性刺激下增加血流涌入，帮助自然产生和维持勃起。它们不是春药，需要性刺激才能起效。
- How they work: These medications work by inhibiting the PDE5 enzyme, increasing the level of a key substance in the penile corpora cavernosa—cyclic guanosine monophosphate (cGMP). This promotes the relaxation of vascular smooth muscles, upon sexual stimulation, increasing blood inflow to help achieve and maintain a natural erection. They are not aphrodisiacs and require sexual stimulation to work.
- 常见药物：
- 西地那非 (Sildenafil)： 品牌名如伟哥 (Viagra®)。通常在活动前30-60分钟服用，药效持续约4-6小时。
- 他达拉非 (Tadalafil)： 品牌名如希爱力 (Cialis®)。起效时间类似，但药效可持续长达36小时，允许更自发的性生活，被誉为“周末药丸”。也有低剂量每日服用方案。
- 伐地那非 (Vardenafil)： 品牌名如艾力达 (Levitra®)。
- 阿伐那非 (Avanafil)： 品牌名如Spedra®。起效可能更快。
- Common medications:
- Sildenafil: Brand names like Viagra®. Usually taken 30-60 minutes before activity, effects last about 4-6 hours.
- Tadalafil: Brand names like Cialis®. Similar onset time, but effects can last up to 36 hours, allowing for more spontaneous sexual activity, known as the “weekend pill.” A low-dose daily regimen is also available.
- Vardenafil: Brand names like Levitra®.
- Avanafil: Brand names like Spedra®. May have a faster onset.
- 重要警示： 绝对禁止与硝酸酯类药物（如硝酸甘油，用于心绞痛）同时使用！ 可能导致危及生命的低血压。必须在医生指导下使用，评估是否适合您。
- Critical Warning: Absolutely contraindicated with nitrate medications (e.g., nitroglycerin for angina)! Can cause life-threatening low blood pressure. Must be used under a doctor’s guidance to assess suitability.
二、物理治疗与器械 | 2. Physical Therapy and Devices
- 真空勃起装置（VED）| Vacuum Erection Device (VED)
- 方法： 由一个塑料圆筒、一个手泵或电池泵和一个收缩环组成。将圆筒套在阴茎上，通过泵产生真空负压，将血液吸入阴茎从而引发勃起，然后将收缩环移至阴茎根部以维持勃起。
- 优点： 非侵入性，无药物副作用，适用于不能服用PDE5抑制剂的男性。
- 缺点： 勃起可能感觉较冷或不自然，使用稍麻烦，收缩环使用时间不宜过长（通常不超过30分钟）。
- Method: Consists of a plastic cylinder, a hand or battery pump, and a constriction ring. The cylinder is placed over the penis, and the pump creates a vacuum to draw blood into the penis, causing an erection. The ring is then moved to the base to maintain it.
- Advantages: Non-invasive, no medication side effects, suitable for men who cannot take PDE5 inhibitors.
- Disadvantages: The erection may feel cooler or less natural; usage is somewhat cumbersome; the ring should not be used for too long (usually no more than 30 minutes).
三、其他医疗干预措施 | 3. Other Medical Interventions
- 阴茎海绵体内注射疗法（ICI）| Intracavernosal Injection Therapy (ICI)
- 方法： 使用极细的针头将血管活性药物（如前列腺素E1/Alprostadil）直接注射到阴茎海绵体侧方。通常在5-15分钟内可诱发勃起。
- 优点： 有效率极高，不受性刺激影响。
- 缺点： 需要学习注射技巧，可能有针刺疼痛或罕见持续勃起（priapism，需急诊）的风险。需医生培训后使用。
- Method: A very fine needle is used to inject vasoactive medication (e.g., Alprostadil) directly into the side of the corpora cavernosa of the penis. Usually induces an erection within 5-15 minutes.
- Advantages: Highly effective, not dependent on sexual stimulation.
- Disadvantages: Requires learning injection technique; may cause injection pain or risk of rare priapism (prolonged erection requiring emergency care). Must be used after doctor training.
- 低强度冲击波治疗（Li-ESWT）| Low-Intensity Shockwave Therapy (Li-ESWT)
- 方法： 一种非侵入性治疗。将低能量冲击波对准阴茎，旨在刺激血管新生和改善局部血流，从潜在病因上改善血管性ED。
- 优点： 无创，可能提供长期改善。
- 现状： 被认为是一种有前景的治疗方法，但长期疗效和最佳方案仍在深入研究中。
- Method: A non-invasive treatment that applies low-energy shockwaves to the penis, aiming to stimulate angiogenesis (new blood vessel formation) and improve local blood flow, addressing the underlying cause of vascular ED.
- Advantages: Non-invasive, may provide long-term improvement.
- Current Status: Considered a promising therapy, but long-term efficacy and optimal protocols are still under extensive research.
四、激素治疗（针对特定人群）| 4. Hormonal Therapy (For a Specific Group)
- 睾酮替代疗法（TRT）| Testosterone Replacement Therapy (TRT)
- 适用对象： 仅适用于经血液检查确诊为临床性低睾酮（性腺功能减退）并伴有相关症状（如性欲显著减退）的ED患者。
- 重要提示： 对于睾酮水平正常的男性，补充睾酮无效且可能有害。需医生严格评估风险和收益，并定期监测。
- For whom? Only for ED patients diagnosed with clinical hypogonadism (low testosterone) via blood tests AND experiencing related symptoms (e.g., significantly low libido).
- Important Note: For men with normal testosterone levels, supplementation is ineffective and potentially harmful. Requires strict doctor assessment of risks and benefits, with regular monitoring.
五、手术治疗（最后的选择）| 5. Surgical Treatment (The Last Resort)
- 阴茎假体植入术 | Penile Implant Surgery
- 方法： 通过手术将可充胀或半硬性的假体植入阴茎海绵体内。充胀式假体可通过阴囊内的小泵充液，模拟自然勃起。
- 适用对象： 对其他所有治疗均无效的严重器质性ED患者。
- 优点： 满意度非常高，允许进行自发性性生活。
- 缺点： 是最终的有创手术，不可逆；有手术风险（如感染、机械故障，但发生率低）。
- Method: Surgery to implant an inflatable or malleable prosthesis into the corpora cavernosa. Inflatable implants can be filled via a small pump in the scrotum, mimicking a natural erection.
- For whom? Patients with severe organic ED that has not responded to all other treatments.
- Advantages: Very high satisfaction rates, allows for spontaneous sexual activity.
- Disadvantages: A final, irreversible invasive surgery; carries surgical risks (e.g., infection, mechanical failure, though发生率低).
给新加坡读者的治疗路径建议 | Treatment Pathway Advice for Singaporean Readers
- 咨询医生 (Consult a Doctor): 前往Polyclinic或泌尿科，这是安全有效的第一步。
- 基础治疗 (Foundational Therapy): 所有患者都应积极改善生活方式（如健康饮食、规律运动、戒烟限酒、管理压力）。
- 一线选择 (First-Line Choice): 医生通常会处方PDE5抑制剂（如他达拉非或西地那非）。请遵医嘱使用。
- 后续选项 (Subsequent Options): 如果口服药无效、禁忌或不耐受，医生可能与您讨论VED、注射治疗或冲击波治疗。
- 最后手段 (Last Resort): 对于严重病例，当所有其他方法都失败时，考虑阴茎假体植入术。
