The correct answer is
In older men, ED usually has a physical cause, such as disease, injury, or side effects of medication. Any disorder that causes injury to the nerves or impairs blood flow in the penis may cause ED, the NIDDK says. Damage to nerves, arteries, smooth muscles, and fibrous tissues, often as a result of disease, is the most common cause of ED. Diseases—such as diabetes, hypertension, kidney disease, chronic alcoholism, multiple sclerosis, atherosclerosis, vascular disease, and neurologic disease—account for about 70 percent of ED cases. Up to half of men with diabetes experience ED.

The correct answer is
If a pre-existing disease, medication, or other cause is determined, it should be treated before using impotence drugs. Oral drugs are available to treat ED. These drugs are not aphrodisiacs, so they have no effect on sexual desire. What they do is physically relax the blood vessels of the penis, allowing it to fill with blood and to stay erect long enough for intercourse. These medications also may cause side effects, so they aren't for everyone. Often, medication is accompanied by counseling, especially because couples seeking help for ED may have emotional issues they need to overcome, as well as the physical problems. Other treatments for ED include injection therapy, in which medication is injected into the penis; insertion of tiny pellets into the penis; bands; vacuum tubes; and surgical implants. If low testosterone is causing the ED, it can be treated with testosterone patches or injections. In rare cases, surgery may be done to improve blood flow to the penis.
