The value of bulbocavernosus reflex latency verses nerve conduction velocity of the dorsal nerve of penis and penile brachial index was evaluated in 50 impotent individuals infected with the human immunodeficiency virus, type 1 (both symptomatic and asymptomatic) and in 50 aged matched HIV-1 sero-negative impotent men serving as controls. All the subjects were neurologically asymptomatic and non demented. Both HIV-1 infected asymptomatic and symptomatic impotent patients exhibited a significant decrease (P < 0.0005) in the nerve conduction velocity of the dorsal nerve of penis as well as penile branchial index from the controls of the same age group. The latency of bulbocavernosus showed no significant difference between the groups and was within the normal limits. A non-significant association in the study parameters between HIV-1 infected asymptomatic and AIDS positive impotent men was also observed. These findings suggest that impotence and altered erectile electrodiagnostic responses are likely to be associated with an increased frequency to neuropathy in these patients irrespective of their disease state.
对50名感染1型人类免疫缺陷病毒的阳痿患者（包括有症状和无症状者）以及50名年龄匹配的HIV-1血清阴性的阳痿男性作为对照，评估了球海绵体反射潜伏期与阴茎背神经传导速度及阴茎肱动脉指数的价值。所有受试者神经学上均无症状且无痴呆。与同年龄组的对照组相比，HIV-1感染的无症状和有症状的阳痿患者阴茎背神经传导速度以及阴茎肱动脉指数均显著降低（P<0.0005）。球海绵体反射潜伏期在两组之间无显著差异且在正常范围内。在HIV-1感染的无症状和艾滋病阳性的阳痿男性的研究参数之间也观察到无显著关联。这些发现表明，无论疾病状态如何，这些患者的阳痿和勃起电诊断反应改变可能与神经病变频率增加有关。
