Some men experience erectile dysfunction as a result of physiological factors, including medications that can interfere with sexual response, chronic illness (e.g., heart disease, high blood pressure, diabetes), physical disability, alcoholism, drug use, or injury that impedes blood flow to the erectile tissue.
