We investigated 7 normal men and 1 diabetic patient with erectile dysfunction. Electromyography electrodes were placed in the corpus cavernosum of the penis and electrical activity was recorded during flaccidity. With sexual arousal the activity decreased and tumescence was initiated. During tumescence and full erection the electrical activity of the corpus cavernosum almost ceased but in the diabetic patient (neurogenic impotence) an increase was observed. This discoordination might be the cause of the erectile dysfunction. Recording the electrical activity of the corpus cavernosum in patients with suspected neurogenic erectile dysfunction could become clinically valuable, since this is the first test possible to study the function of the autonomic motor system that normally regulates penile function.
我们对7名正常男性和1名患有勃起功能障碍的糖尿病患者进行了研究。将肌电图电极置于阴茎海绵体内，并在阴茎疲软状态下记录电活动。随着性唤起，电活动减少，阴茎勃起开始。在勃起过程和完全勃起时，海绵体的电活动几乎停止，但在该糖尿病患者（神经性阳痿）中观察到电活动增加。这种不协调可能是勃起功能障碍的原因。记录疑似神经性勃起功能障碍患者海绵体的电活动可能具有临床价值，因为这是首个能够研究正常调节阴茎功能的自主运动系统功能的检测方法。
