Diurnal penile plethysmography under visual sexual stimulation (VSS) and nocturnal penile tumescence (NPT) plethysmography have been performed in 5 healthy volunteers and 195 consecutive men complaining of impotence. Our study demonstrates that VSS plethysmography may compensate at least partially for the shortcomings of classic NPT plethysmography, by allowing direct clinical estimation of "erectile performance." Twenty percent of the patients had full erection under VSS. These patients do not need further testing. VSS is a noninvasive and useful "first-line" investigation in erectile dysfunction.
对5名健康志愿者以及195名连续前来抱怨阳痿问题的男性进行了视觉性刺激（VSS）下的阴茎体积描记法以及夜间阴茎胀大（NPT）体积描记法。我们的研究表明，VSS体积描记法可以通过直接临床评估“勃起功能”，至少部分弥补经典NPT体积描记法的不足。20%的患者在VSS下能够完全勃起。这些患者无需进一步检查。VSS是勃起功能障碍的一种无创且有用的“一线”检查方法。
