Abstract

Twenty-nine premature ejaculation patients entered this study using audiovisual stimulation penogram(AVS-Penogram) to evaluate their dynamic blood flows in the penis. The patients, ages twenty seven through fifty-two(average 34 years), complained of short time-to-coital ejaculation less than 90 seconds. We performed Bulbocavernous Reflex Latency(BCRL) and Pudendal Nerve Somatosensory Evoked Potential (DNSEP) test in nineteen of them. According to the results of audiovisual stimulation penogram the patients were classified into two group: fifteen patients had type I (normal) finding and fourteen patients had type X a(unstable erection due to severe fluctuation in blood flow) Finding. Five patients(33%) of fifteen patients with type I (normal) penogram and eleven patients(78%) of fourteen patients with unstable type II n penogram complained of concomitant erectile failure(p<0.06). The age, time-to-coital ejaculation and the results of expressed prostatic secretion(EPS) were not statistically different between above two groups. Furthermore, all cases in whom BCRL and DNSEP was performed had normal results in both tests. This study indicates that premature ejaculation can occur combined with organic erectile failure seeing that the patients show an unstable hemodynamics, and that in such case premature ejaculation has to be treated with underlying organic causes of impotence.
