阳痿(勃起功能障碍,Erectile Dysfunction)的症状不仅限于性行为中的表现,还可能反映全身健康问题。新加坡男性健康协会指出,70%的ED患者在确诊前忽视早期症状。本文将详细解析ED的典型表现、分级标准及本地就医建议。
一、典型症状 | Core Symptoms
1. 勃起困难 | Difficulty Achieving Erection
- 轻度症状:需强烈性刺激才能勃起,且硬度不足以完成性行为。
Mild ED: Requires intense stimulation to get erect, with insufficient hardness for penetration. - 中度症状:偶发完全无法勃起(如每月2-3次)。
Moderate ED: Occasional total erection failure (e.g., 2-3 times/month). - 重度症状:长期无法获得任何勃起反应。
Severe ED: Chronic inability to achieve any erection.
新加坡案例:
40岁IT从业者因长期久坐出现轻度ED,初期表现为晨勃减少(每周<2次)。
A 40-year-old Singaporean IT worker with mild ED initially noticed reduced morning erections (<2/week).
2. 勃起维持障碍 | Difficulty Maintaining Erection
- 性行为中勃起突然消退,需反复刺激才能恢复。
Erection fades during intercourse, requiring constant stimulation to regain.
科学机制:阴茎海绵体供血不足或静脉渗漏。
Underlying cause: Insufficient blood flow to corpora cavernosa or venous leakage.
3. 性欲减退 | Reduced Libido
- 对性活动兴趣显著下降,可能与睾酮水平降低相关。
Loss of interest in sex, often linked to low testosterone levels.
本地数据:新加坡40岁以上男性中,**25%**因睾酮<12 nmol/L出现性欲问题。
25% of Singaporean men over 40 have libido issues due to testosterone <12 nmol/L.
二、伴随症状 | Associated Symptoms
1. 心理影响 | Psychological Effects
- 焦虑或抑郁:因ED产生的自我怀疑可能形成恶性循环。
Anxiety/depression: Self-doubt from ED creates a vicious cycle.
研究证实:新加坡ED患者中,**45%**因心理压力加重症状。
45% of Singaporean ED patients experience symptom worsening due to stress.
2. 全身健康信号 | Systemic Health Indicators
- 心血管风险:ED可能是心脏病早期征兆(早于胸痛症状2-3年)。
Cardiovascular risk: ED can signal heart disease 2-3 years before chest pain. - 糖尿病关联:勃起硬度下降常早于糖尿病确诊1-2年。
Diabetes link: Reduced erection hardness often precedes diabetes diagnosis by 1-2 years.
三、症状分级与自测 | Severity Assessment & Self-Check
国际勃起功能指数(IIEF-5)自测表
问题示例:
- 对获得勃起的信心如何?
How confident are you in getting an erection?- 0分:毫无信心
- 5分:非常自信
- Score 0: No confidence → Score 5: High confidence
结果判定:
- 22-25分:正常
- 12-21分:轻度ED
- 8-11分:中度ED
- 5-7分:重度ED

四、何时就医? | When to See a Doctor?
红色警报症状 | Red Flags
- 突发性ED:72小时内突然无法勃起,可能提示心血管事件。
Sudden ED: Inability to erect within 72 hours may indicate heart attack/stroke. - 疼痛性勃起:伴随阴茎疼痛或弯曲,需排除佩罗尼氏病。
Painful erection: May suggest Peyronie’s disease (penile curvature).
推荐医疗机构 | Recommended Clinics
- 公立医院:新加坡中央医院(SGH)泌尿科。
Public: SGH Urology Department. - 私立诊所:伊丽莎白诺维娜医院男性健康中心。
Private: Men’s Health Centre at Mount Elizabeth Novena.
五、新加坡就医流程 | Medical Consultation Process in Singapore
- 初步检查:血压、血糖、睾酮水平检测(综合诊所可完成)。
Initial tests: Blood pressure, glucose, testosterone (available at polyclinics). - 专科转介:若疑似器质性ED,转至泌尿科进行夜间勃起监测(NPT)。
Specialist referral: Urologists may conduct nocturnal penile tumescence (NPT) tests. - 治疗方案:根据病因选择口服药物(如PDE5抑制剂)、低强度冲击波疗法(Li-ESWT)或心理治疗。
Treatment options: Oral medications (e.g., Viagra), shockwave therapy, or counselling.
