Unexpected Causes of Erectile Dysfunction: 4 Reasons You Might Not Have Considered​

当谈到勃起功能障碍（阳痿）时，人们通常会想到压力、年龄或心血管疾病等常见原因。然而，有些潜在因素往往被忽视，却对男性健康有着深远影响。本文将揭示四个意想不到的阳痿成因，帮助新加坡男性更全面地守护自身健康。

When discussing Erectile Dysfunction (ED), common causes like stress, aging, or cardiovascular disease often come to mind. However, certain underlying factors are frequently overlooked yet have a profound impact on men’s health. This article reveals four unexpected causes of ED to help men in Singapore protect their well-being more comprehensively.

​1. 睡眠呼吸暂停：夜间缺氧的隐形威胁 | Sleep Apnea: The Hidden Threat of Nighttime Oxygen Deprivation

​

许多人不会将打鼾与性功能联系起来，但严重的打鼾（特别是睡眠呼吸暂停）却是导致阳痿的一个隐形杀手。睡眠呼吸暂停患者在夜间会反复出现呼吸中断，导致身体缺氧。这种慢性缺氧状态会损害血管内膜功能，影响全身的血液循环，包括流向阴茎的血液。同时，睡眠质量差会降低睾酮水平，进一步加剧勃起困难。对于经常感到白天疲劳、注意力不集中的男性，评估睡眠质量可能是解决阳痿的关键一步。

Many people don’t connect snoring with sexual function, but severe snoring, particularly sleep apnea, is a hidden culprit behind ED. Individuals with sleep apnea experience repeated breathing interruptions during sleep, leading to oxygen deprivation. This chronic state of hypoxia damages blood vessel lining function, impairing blood circulation throughout the body, including blood flow to the penis. Furthermore, poor sleep quality lowers testosterone levels, further exacerbating erectile difficulties. For men who often feel daytime fatigue and have difficulty concentrating, assessing sleep quality could be a crucial step in addressing ED.

​2. 长期骑行：坐垫压迫的慢性损伤 | Long-Term Cycling: Chronic Damage from Saddle Compression​

新加坡鼓励绿色出行，骑行已成为流行的通勤和运动方式。然而，传统的狭窄自行车坐垫会长时间压迫会阴部，损伤负责勃起功能的神经和血管。这种压迫是渐进性的，初期可能只是感觉麻木，但长期累积可能导致血管内皮功能受损和神经敏感度下降。选择合适的坐垫（如中空减压坐垫）、调整骑行姿势、以及避免连续长时间骑行，对预防此类损伤至关重要。

Singapore promotes green travel, and cycling has become a popular mode of commute and exercise. However, traditional narrow bicycle saddles can compress the perineum for extended periods, damaging the nerves and blood vessels responsible for erectile function. This compression is progressive; initial symptoms might only be numbness, but long-term accumulation can lead to impaired vascular endothelial function and reduced nerve sensitivity. Choosing an appropriate saddle (such as a hollow, pressure-relief saddle), adjusting riding posture, and avoiding consecutive long-distance rides are crucial for preventing such damage.

​3. 常见处方药的副作用 | Side Effects of Common Prescription Medications​

某些治疗其他疾病的常用药物，其副作用可能包括影响勃起功能。例如：

• ​抗抑郁药​（特别是SSRIs类）：虽然用于改善情绪，但可能通过影响血清素水平延迟射精或导致勃起困难。
• ​高血压药物​：某些β-受体阻滞剂和利尿剂可能影响血流或性欲。
• ​前列腺药物​：如5α-还原酶抑制剂可能影响性功能。
  ​重要提示​：如果您怀疑正在服用的药物可能导致ED，切勿自行停药。应咨询开具处方的医生，讨论调整剂量或更换药物的可能性。

The side effects of certain common medications for other conditions can include impacting erectile function. Examples include:

• ​Antidepressants​ (especially SSRIs): While used to improve mood, they can delay ejaculation or cause ED by affecting serotonin levels.
• ​Blood pressure medications: Some beta-blockers and diuretics may affect blood flow or libido.
• ​Prostate medications: Drugs like 5-alpha-reductase inhibitors can impact sexual function.
  ​Important Note: If you suspect your medication is causing ED, do not stop taking it yourself. Consult the prescribing doctor to discuss adjusting the dosage or switching medications.

​4. 情感亲密感的缺失 | Lack of Emotional Intimacy​

阳痿并非总是纯生理问题。在长期伴侣关系中，情感亲密感的流失——例如沟通不畅、持续未解决的冲突、或情感距离——会显著影响性功能。当关系中的情感连接减弱时，即使生理上完全健康，男性也可能出现心理性ED。大脑是最大的性器官，情感上的疏远或怨恨会抑制性兴奋的神经通路。因此，投资于情感关系，改善沟通，有时比寻求药物更有效。

ED is not always purely physical. In long-term partnerships, the loss of emotional intimacy—such as poor communication, unresolved conflicts, or emotional distance—can significantly impact sexual function. When the emotional connection in a relationship weakens, a man might experience psychologically induced ED even if he is physically healthy. The brain is the most important sexual organ; emotional distance or resentment can inhibit the neural pathways of sexual arousal. Therefore, investing in the emotional relationship and improving communication can sometimes be more effective than seeking medication.

​总结 | Conclusion​
了解这些意想不到的原因，有助于我们更全面地看待男性健康。如果正经历勃起困难，除了考虑常见因素外，不妨从睡眠模式、运动习惯、用药情况以及情感关系等方面进行审视。在新加坡，勇敢地与医生讨论这些话题，是获得准确诊断和有效治疗的第一步。记住，关注这些细节，往往能找到解决问题的关键钥匙。

Understanding these unexpected causes helps us view men’s health more holistically. If experiencing erectile difficulties, besides considering common factors, it’s worthwhile to examine sleep patterns, exercise habits, medication use, and emotional relationships. In Singapore, having the courage to discuss these topics with a doctor is the first step towards an accurate diagnosis and effective treatment. Remember, paying attention to these details often holds the key to resolving the problem.
