International Index of Erectile Function (IIEF-5)

IIEF5, a simplified version of the International Index of Erectile Function, is a self-administered questionnaire consisting of 5 questions with a score from 0 to 5 per question. The IIEF5 is a semi-quantified assessment of erectile dysfunction. It was developed in the United States by Pr. Rosen and has since been translated and validated in many languages, including French.
