We evaluated the relevance of patient reported sex history information in predicting erectile functioning as measured by the RigiScan monitor. A total of 46 male veterans who presented with erectile dysfunction completed an extensive medical and psychological evaluation including a sexual history, and then underwent 2 consecutive nights of inhospital RigiScan sleep evaluation performed under supervision. Multivariate analyses indicated a significant relationship among patient reported sex history information, and RigiScan measurements of tip and base duration, and rigidity. The sex history item with the greatest predictive power was the question regarding early morning erections. The results of this study highlight the importance of patient reported information, and the significance of obtaining a detailed sex history in the evaluation of older, primarily chronically ill patients who present with erectile dysfunction.
