The value of testing pudendal nerve conduction in evaluating erectile dysfunction in diabetics.
We conducted an open prospective study on the value of testing pudendal nerve conduction (PNC) in 45 diabetic and 32 nondiabetic men with documented erectile dysfunction (ED) of at least six months duration. All subjects underwent PNC by the same investigator using the Medcelec/TECA Sapphire device with calibration parameters of sweep 10 ms/div an amplitude of 200 microV/div. No statistically significant differences was found in the mean bulbocavernosus reflex (BCR) latencies between the nondiabetics (33.6 ms/div +/- 4.1) and the diabetics (37.5 ms/div +/- 9.1) (P > 0.05). Our results show that electrophysiological measurement of the BCR in diabetics is not a useful diagnostic test and emphasize the importance of a multifactorial evaluation of diabetic ED.
