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 excitation 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.
CONCLUSIONS
Based on our results, the earlier excitation of the sacral reflex arc might be related to premature ejaculation. (J Korean Neurol Assoc 19(5):494~497, 2001)
