  • Endocrine
  1. Diabetes Mellitus (most common)

    2. Abnormal Glucose tolerance in 15% men with Impotence (ED may be an indicator sign for undiagnosed DM)
    3. Confers 3 fold increased Erectile Dysfunction (esp. with longer duration of Diabetes Mellitus)
  2. Metabolic Syndrome and Obesity
    1. Low Serum Testosterone
    2. Excessive aromatase (in adipose) converts Testosterone to Estradiol
    3. Confers 2.6 fold increased Erectile Dysfunction (esp. with higher Fasting Glucose)

  1. Coronary Artery Disease
    1. Shares similar risks for Erectile Dysfunction
    2. Erectile Dysfunction is diagnosed 2-5 years before Coronary Artery Disease
