Current status of standardized questionnaires in the measurement of erectile dysfunction.

The evaluation and management of erectile dysfunction has evolved dramatically over the past decade. Clinicians now benefit from advances in the understanding of the physiologic pathways involved in the function of erections and from the availability of innovative and effective therapies. The clinical history remains the essential starting point in the evaluation of patients with erectile dysfunction. The standardized questionnaire has been used as a valuable complement to the clinical history and in the assessment of treatment efficacy.
