Further evidence that nocturnal erections are androgen-dependent and erectile responses to visual erotic stimuli are androgen-independent is presented from six men with secondary hypogonadism and six eugonadal controls. Erections during sleep were substantially less in the hypogonadal men, in terms of both tumescence and rigidity. In response to visual erotic stimuli, the percentage increase in circumference over baseline and the increase in rigidity were similar for the two groups.
来自六名继发性性腺功能减退男性和六名性腺功能正常对照者的进一步证据表明，夜间勃起依赖雄激素，而对视觉性刺激的勃起反应不依赖雄激素。性腺功能减退男性睡眠期间的勃起，无论是肿胀程度还是硬度，都明显较少。对于视觉性刺激，两组阴茎周长相对于基线的增加百分比和硬度增加情况相似。
