[Mechanisms of diabetic impotence. 25 cases].
Twenty-five impotent diatetics were investigated by means of nocturnal penile tumescence monitoring, hormone determinations, penile blood pressure measurement, artificial erection test and dynamic cavernosography, bulbocavernous reflex latency time measurement and cortical evoked responses from pudendal nerves. Sexological treatment was then attempted for a better evaluation of the psychogenic element. Penile blood pressure was also measured in 15 non-impotent diabetics and was found to be abnormal as often as in impotent diabetics. The results as a whole demonstrated that impotence was predominantly psychogenic in 9 cases, predominantly organic in 12 cases and mixed psychogenic and organic in 4 cases. Diabetic impotence is often due to several causative factors, as was the case in 12 of our patients. The factors most frequently responsible were psychological (present in 13 cases), neurological (present in 12 cases) and vascular factors (arterial abnormalities in 7 cases, "venous leakage" in 4 cases). Endocrine abnormalities were observed in only 2 cases.
