Sympathetic skin potentials were recorded from the hand and genital region in 14 normal potent men and 18 patients with premature ejaculations. With the penis flaccid the sympathetic skin potentials obtained did not differ significantly in both groups. However, when erection was induced by 50 mg. intracavernous papaverine injection, the genital sympathetic skin potentials were significantly suppressed in all but 3 normal men, while the hand potentials did not change. In subjects with premature ejaculation genital and hand sympathetic skin potentials were suppressed during erection as a generalized bodily reaction except in 1 patient. This phenomenon may indicate that the specific and regional suppression of genital sympathetic activity during erection could not be properly adjusted in patients with premature ejaculation.
对14名性功能正常的男性和18名早泄患者的手部及生殖器区域进行了交感神经皮肤电位记录。在阴茎疲软状态下，两组所测得的交感神经皮肤电位并无显著差异。然而，当通过海绵体内注射50毫克罂粟碱诱发勃起时，除3名正常男性外，其他所有正常男性的生殖器交感神经皮肤电位均显著受到抑制，而手部电位则未发生变化。在早泄患者中，除1名患者外，其余患者在勃起过程中生殖器和手部交感神经皮肤电位均作为全身性身体反应受到抑制。这种现象可能表明，早泄患者在勃起过程中生殖器交感神经活动的特异性和区域性抑制未能得到适当调节。
