[Erectile dysfunction: a multidisciplinary approach].

In 1985, a multidisciplinary investigation was carried out on 134 patients suffering from erectile dysfunction (mean age 37.5 years). The study comprised medical and sexual history, physical examination, laboratory tests, psychological interview and psychometrics, nocturnal penile-tumescence (NPT) measurements, bulbocavernosus-reflex (BCR) latency, and penile Doppler sonography. If indicated, we performed additional autoinjection of the corpus cavernosum (CCAT) with vasoactive agents, dynamic cavernosography, and bilateral selective pudendal arteriography. Thus we found an organic cause in 85% of the cases, revealing a vascular disease in 76%.
