Understanding Erectile Dysfunction Medications (cont.)

What Causes Erectile Dysfunction?

ED can be caused by any number of physical and psychological factors. In general, ED is classified according to whether it is caused by organic (having to do with a bodily organ or organ system) or psychogenic (mental) factors. Diseases, nutritional status, trauma, surgical procedures, or medications can affect erectile function by altering the nervous, vascular, or hormonal systems. Some men have more than one cause for their ED.
