Question: Define erectile dysfunction (ED)?


ED is the inability to obtain and maintain an erection sufficient for sexual intercourse. ED is usually multifactorial in etiology, and most men have at least some psychogenic factors that contribute to the disorder (i.e., performance anxiety can exacerbate underlying organic etiology).
