The relationships among penile segmental pulsatile blood flow, pelvic musculovascular events, phases of nocturnal penile tumescence, and sleep stages were studied by all-night polysomnography in 23 healthy middle-aged men. Penile blood flow peaked during maximal tumescence. Bursts of phasic musculovascular activity were more frequent during ascending and maximal tumescence than during detumescence and baseline. Both penile blood flow and the number of musculovascular events increased during REM sleep. These data describe important local aspects of penile erectile mechanisms in normal men. The findings on musculovascular events support the notion that the bulbocavernosus-ischiocavernosus muscles have a role in human penile erection.
通过对23名健康中年男性进行整夜多导睡眠监测，研究了阴茎节段性搏动血流、盆腔肌肉血管活动、夜间阴茎勃起阶段和睡眠阶段之间的关系。阴茎血流在最大勃起时达到峰值。与疲软和基线期相比，在勃起增强期和最大勃起期，阶段性肌肉血管活动的爆发更为频繁。在快速眼动睡眠期间，阴茎血流和肌肉血管活动的次数均增加。这些数据描述了正常男性阴茎勃起机制的重要局部特征。关于肌肉血管活动的研究结果支持球海绵体肌-坐骨海绵体肌在人类阴茎勃起中起作用的观点。
