Of 79 men in whom clinical and laboratory examinations revealed no organic cause for their impotence; 20 men received testosterone, 21 received trazodone, 20 underwent hypnosis and 18 served as placebo controls. They were assessed by interview 4, 6 and 8 weeks after starting treatment: the patient’s reports were verified by interviewing their partners. Placebo men had a 39% improvement in sexual function v. rates of improvement in the testosterone, trazodone and hypnosis groups of 60%, 67% and 80%, respectively, none of which reached significance.
