What Factors Are Linked to Erectile Dysfunction? A Bilingual Analysis (English & Chinese)

Posted on by Afrodisiak Kedai

Erectile dysfunction (ED), or impotence, is a complex condition influenced by multiple physical, psychological, and lifestyle factors. Globally, over 150 million men suffer from ED, with prevalence rising sharply after age 40 (source: Journal of Urology). This article breaks down the key factors linked to ED, providing actionable solutions for prevention and management.
勃起功能障碍（ED，俗称阳痿）是由多种生理、心理及生活习惯因素共同作用的复杂病症。全球有超1.5亿男性受ED困扰，且40岁后发病率显著上升（数据来源：《泌尿学杂志》）。本文解析ED的关联因素，并提供实用的预防与管理方案。

1. Physical Health Factors 生理健康因素

Cardiovascular Disorders 心血管疾病

ED is often an early warning sign of heart disease. Narrowed arteries (atherosclerosis) reduce blood flow to the penis. A 2023 study in Circulation found that 64% of men with ED later developed cardiovascular issues.
ED常是心脏病的早期信号。动脉狭窄（动脉粥样硬化）会减少阴茎血流。《循环》杂志2023年研究表明，64%的ED患者后续出现心血管问题。

Diabetes and Metabolic Syndrome 糖尿病与代谢综合征

High blood sugar damages nerves and blood vessels critical for erections. The International Journal of Impotence Research states that diabetic men are 3x more likely to develop ED than non-diabetics.
高血糖会损伤勃起所需的神经与血管。《国际性功能障碍研究杂志》指出，糖尿病患者患ED的风险是非糖尿病者的3倍。

Hormonal Imbalances 荷尔蒙失调

Low testosterone levels (hypogonadism) reduce libido and erectile function. Thyroid disorders and excess prolactin (hyperprolactinemia) can also contribute.
睾酮水平低下（性腺功能减退）会降低性欲与勃起功能。甲状腺疾病或催乳素过高（高催乳素血症）也可能导致ED。

2. Psychological Triggers 心理诱因

Chronic Stress and Anxiety 长期压力与焦虑

Stress activates the sympathetic nervous system, inhibiting the relaxation of penile muscles. Research from Johns Hopkins University links high-stress jobs to a 45% higher ED risk.
压力会激活交感神经系统，抑制阴茎肌肉松弛。约翰霍普金斯大学研究表明，高压工作使ED风险增加45%。

Depression and Relationship Issues 抑郁与伴侣关系问题

Depression alters brain chemistry (e.g., serotonin/dopamine), while unresolved conflicts with a partner create emotional barriers to intimacy.
抑郁会改变脑化学物质（如血清素/多巴胺），而伴侣间的矛盾会形成情感隔阂，影响亲密行为。

3. Lifestyle and Environmental Risks 生活习惯与环境风险

Smoking and Alcohol Abuse 吸烟与酗酒

  • Smoking: Nicotine causes vasoconstriction, reducing blood flow. Smokers have 2x higher ED rates (source: European Urology).
    吸烟：尼古丁导致血管收缩，减少血流。吸烟者的ED发病率高2倍（来源：《欧洲泌尿学》）。
  • Alcohol: Chronic heavy drinking damages nerves and lowers testosterone.
    酗酒：长期酗酒损伤神经并降低睾酮水平。

Obesity and Sedentary Habits 肥胖与久坐

Excess body fat increases inflammation and estrogen levels, disrupting hormonal balance. A 2024 meta-analysis confirmed that losing 10% body weight improves ED symptoms in 30% of men.
过量脂肪增加炎症和雌激素水平，扰乱荷尔蒙平衡。2024年荟萃分析证实，减重10%可使30%男性的ED症状改善。

4. Medications and Medical Treatments 药物与医疗因素

  • Antidepressants (SSRIs): 30-60% of users report ED as a side effect (source: Mayo Clinic).
    抗抑郁药（SSRIs）：30-60%的使用者出现ED副作用（来源：梅奥诊所）。
  • Prostate Surgery: Nerve damage during procedures like radical prostatectomy may cause temporary or permanent ED.
    前列腺手术：根治性前列腺切除术等可能损伤神经，导致暂时或永久性ED。

Prevention and Management 预防与管理

Medical Interventions 医疗干预

  • Oral Medications: PDE5 inhibitors (e.g., Viagra) enhance blood flow.
    口服药物：PDE5抑制剂（如伟哥）可促进血流。
  • Shockwave Therapy: Non-invasive treatment to regenerate blood vessels (70% efficacy per Sexual Medicine Reviews).
    冲击波疗法：非侵入性血管再生治疗（70%有效性，来源：《性医学评论》）。

Lifestyle Modifications 生活方式调整

  • Diet: Focus on antioxidants (berries, dark chocolate) and omega-3s (salmon, walnuts) to combat inflammation.
    饮食：多摄入抗氧化剂（浆果、黑巧克力）和Omega-3（三文鱼、核桃），对抗炎症。
  • Exercise: Aerobic workouts (e.g., brisk walking 30 mins/day) boost nitric oxide production.
    运动：有氧运动（如每日快走30分钟）促进一氧化氮生成。

Conclusion 结论

ED is rarely caused by a single factor—it’s a interplay of physical health, mental state, and daily habits. Early diagnosis and a holistic approach (medical + lifestyle changes) can restore sexual health in most cases.
ED极少由单一因素引起，而是生理健康、心理状态与日常习惯共同作用的结果。早期诊断与综合治疗（医疗+生活方式调整）可在多数情况下恢复性健康。
