Endothelial dysfunction, a marker for atherosclerosis and hence arterial disease, has recently been proffered as the main offender within the vascular system to predict not only the future onset of erectile dysfunction (ED) but also as the main cause of the ED. To glean more insight into whether arterial disease is indeed operative during the early onset of ED, we reviewed the duplex ultrasound scans of 23 men with ED who were younger than 50 years of age. Depending on the criteria used for abnormal arterial responses, it was determined in this cohort of young men that there was only a 4-13% incidence of abnormal arterial responses. These observations suggest that the penile arterial system does not appear to be primarily involved in the etiology of the majority cases of ED that occur in young men.
内皮功能障碍是动脉粥样硬化和动脉疾病的标志物，最近被提出作为血管系统中的主要罪魁祸首，不仅可以预测勃起功能障碍（ED）的未来发生，还可以作为 ED 的主要原因。为了更深入地了解动脉疾病是否确实在 ED 的早期发作中起作用，我们回顾了 23 名年龄小于 50 岁的 ED 男性的双功能超声扫描结果。根据异常动脉反应的标准，在这个年轻男性队列中，只有 4-13%的人存在异常动脉反应。这些观察结果表明，阴茎动脉系统似乎不是大多数发生在年轻男性的 ED 病例的主要病因。
