To assess the severity of the erectile dysfunction, the patient should be asked about onset and frequency. A standardized questionnaire, such as the International Index of Erectile Dysfunction, is often used. It includes 15 questions about the quality of erectile function and sexual intercourse (Fig. 81-3). The physician should carefully assess the patient s expectations and motivations for erectile function to ensure that they are reasonable.
