[The diagnosis of sexual function disorders. Screening studies of angiological factors in disorders of sexual function].

106 outpatients, visiting our department because of sexual disturbances, underwent a standardized examination program. The following anamnestic data and clinical and laboratory findings were recorded: Details of the vita sexualis, evidences for genital and vascular diseases, endocrine abnormalities including diabetes mellitus, drug consumption. Genital organs were judged by clinical examination, blood-pressure, oscillography and penis-flow-index were measured, hormones, sugar and lipids in blood serum were determined, with respect to a special indication, cavernosography and pelvic angiography were performed, and prostatic inflammation was excluded. None of the anamnestic data differ in its frequency from that of the total population. Mean blood pressure, oscillographic indices, hormone levels, and lipids were found within the normal range. Only a high rate of diabetes mellitus (6%) in all patients and a high rate of pathologic penis-flow-index in men between 40 and 60 years of age were found. We conclude from our results, that medical history and laboratory findings in general will indicate no pathogenetic mechanism in impotence. Just the recording of penile blood flow will give positive correlations.
