We studied 52 men with electrophysiologic testing of the bulbocavernosus reflex to determine reflex latency. The bulbocavernosus reflex was demonstrated to be a segmental polysynaptic reflex with cross-over in the sacral spinal cord. Excellent correlation was obtained between prolonged latency and clinical evidence of neuropathy. The examination may be useful clinically to evaluate patients suspected to have sacral cord lesions or pudendal neuropathy (for example impotence, chronic back pain and lesions of the cauda equina and peripheral nerves).
我们对52名男性进行了球海绵体反射的电生理测试，以确定反射潜伏期。结果表明，球海绵体反射是一种节段性多突触反射，在骶脊髓处交叉。潜伏期延长与神经病变的临床证据之间存在良好的相关性。该检查在临床上可能有助于评估疑似患有骶脊髓病变或阴部神经病变的患者（例如阳痿、慢性背痛以及马尾和周围神经病变）。
