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 it.

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 (spongy tissue chambers in the penis that fill with blood during an erection).

Vascular disease can restrict blood flow to the heart, brain, penis, lower extremities, and other locations within the body.

9. TRUE: Surgery to treat prostate cancer can result in erectile dysfunction, 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, radioactive 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.
