Answers

  1. FALSE: Most men will experience ED at one time or another. ED is a common complaint among men, occurring in about 52% of men aged 40-70.
  2. TRUE: If ED occurs more than 50% of the time, a man should consider seeking medical advice and treatment. ED may be associated with other conditions such as diabetes, coronary artery disease, hypertension, and depression. The presence of ED may be an early sign of these conditions.
  3. FALSE: The causes of ED can be psychological, physical and/or a combination of both. Nonetheless, it is believed that physical causes for ED may occur in a large majority of men who have ED.
  4. FALSE: The sequence of events resulting in an erection involves nerve impulses in the brain, spine and penis. Also involved are the subsequent responses in the body's muscles, fibrous tissues, veins, and arteries in and near the corpora cavernosa (chambers in the penis that are filled with spongy tissue).
  5. TRUE: Kidney disease can cause chemical changes in the body. These changes can affect hormones, circulation, nerve and muscle function, and energy level, all of which can affect a man's ability to achieve and maintain and erection.
  6. TRUE: Diabetes can cause nerve and artery damage that can make achieving an erection difficult. ED may occur in 50% or more of men with diabetes.
  7. FALSE: There are more than 200 kinds of prescription drugs that may be associated with ED and other sexual dysfunction.
  8. TRUE: Vascular diseases are those that affect the blood vessels. These diseases include atherosclerosis (build-up of cholesterol plaques), hypertension, diabetes, and coronary artery disease. Vascular disease can restrict blood flow to the heart, brain, penis, lower extremities, and other locations within the body.
  9. TRUE: Surgery to remove prostate cancer can result in erectile problems, even though prostate cancer alone does not cause ED. It is important to understand that all current treatments for prostate cancer -- including external beam radiation, seeds (brachytherapy), and hormones -- may result in erectile dysfunction.
  10. FALSE: All three of these substances can damage blood vessels and/or restrict blood flow to the penis, causing ED.
