Study of erectile dysfunctions in diabetic males.

The incidence of sexual dysfunction in 75 diabetic adult males was 45.33 percent. The evaluation utilized (a) psychosexual history, (b) Nocturnal penile tumescence (NPT) monitor, (c) bulbocavernous (BC) muscle EMG and BC reflex study, (d) Doppler indices for penile blood flow, (e) serum testosterone and prolactin assay. Nineteen patients (55.88 percent) had underlying psychogenic factors and 15 (44.12 percent) had organic factors (7 neurogenic, 5 vasculogenic, 3 combined neuro-and vasculogenic). The correct aetiologic evaluation may help in achieving therapeutic success.
