Abstract

"Background : Though its cause has not been well established, premature ejaculation is the most prevalent form of male sexual dysfunction. Some recent studies suggest that penile hypersensitivity and hyperexcitability, earlier excita-tion of the sacral reflex arc, and abnormality with peripheral and central afferent nerve conduction pathways, are related to premature ejaculation. Methods : The bulbocavernous reflex latency (BCRL) test and dorsal nerve somatosensory evoked potential (DNSEP) test were done in 15 normal subjects (mean age: 38.2 years) and 30 premature ejaculation patients (mean age: 40.2 years) without history of neurological disorders nor history of medication which influences the nervous system. Results : The mean latency of BCR was shortened significantly in patients with premature ejaculation (33.1±3.08 msec) than in the control group (37.2±3.95 msec)(P<0.01). However, there were no significant differences in latency and amplitude of DNSEP tests between the two groups. Onclusions : Based on our results, the earlier exci-tation of the sacral reflex arc might be related to premature ejaculation.
