Pudendal nerve conduction to evaluate organic erectile dysfunction

Objective: This study aimed to evaluate the value of testing pudendal nerve conduction in men with erectile dysfunction. Design: This open prospective study was conducted on 150 men with documented erectile dysfunction of at least 6 mo of duration, ail of whom underwent pudendal nerve conduction by the same investigator.Results: Only patients with erectile dysfunction and low back pain (n = 9) showed statistically significant prolonged pathologic pudendal nerve conduction latency of 43.1 msec/div (SD ± 11.3 msec/div, P < 0.05). There were no correlations between the pudendal nerve conduction latency in patients suffering from erectile dysfunction associated with diabetes mellitus, local trauma, pelvic surgery, or antihypertensive drugs. Conclusions: Pudendal nerve conduction may contribute valuable information to the evaluation of patients with erectile dysfunction caused by neurologic deficits as manifested by low back pain.
