ED is caused by vascular, hormonal, neurogenic, pharmacological, or psycho-genic factors. Performance anxiety where the person fears failing in a sexual scenario is a common psychogenic cause for ED.3 Neurogenic causes are related to diseases like Alzheimer's, Parkinson's, stroke or spinal cord injuries. Radical removal of the prostate (also called prostatectomy) is the cause of nerve-related ED as nerve injury is possible despite advances in surgical methods.4

Diseases like diabetes, cardiovascular disease, atherosclerosis, kidney disease, obesity, multiple sclerosis, and depression, and activities like bicycling, smoking, alcohol or drug abuse can impair blood flow or nerve impulses throughout the body. Surgery, as well as certain medications, can also result in ED. However, this may be a temporary problem.4
When it comes to boosting sexual performance, many men will walk all over God’s green earth looking for ways to maintain a good sex life. Luckily men, all you have to do is walk — not run — 2 miles a day. This, along with other healthier lifestyle interventions can help obese men reduce their risk of ED, or even “reverse” current impotence, according to a 2005 study. This comes of importance, since maintaining a trim waistline is a good defense for ED, as men with a 42-inch waist are 50 percent more likely to have ED than those with a 32-inch waist. Getting to a healthy weight and maintaining it is a good strategy for preventing and treating ED.
Energy-boosting goji berries have been used for thousands of years in Chinese medicine to help increase energy and enhance the release of hormones. Goji increases the body’s ability to handle stress and support healthy mood, mind and memory—all while giving you the get-up-and-go energy needed to get your workout to the next level,” says Dr. Lindsey Duncan, celebrity nutritionist (he’s worked with Tony Dorsett and Reggie Bush). “Goji is also beneficial for increasing blood flow, which helps to oxygenate all of the cells and tissues of the body, which increases your drive—that’s why they call goji the ‘Viagra of China.’”
Sure, it’s good for your cholesterol, but did you know red wine can benefit your manhood? Red wine contains nitric oxide, which helps relax the arteries and increase blood flow in the genitals, and the compound quercetin, which helps block the enzyme that triggers your body to push away testosterone, allowing you to maintain high levels of testosterone—and a strong erection well past foreplay.
Wine – especially red wine – is a great source of the antioxidant phytochemical resveratrol, which helps open the arteries by enhancing the production of nitric oxide. Nitric oxide allows the blood vessels to expand, and this is how Viagra works. But while the little blue pill only works on tiny blood vessels, resveratrol helps your main arteries too. Make sure you stop at one or two glasses of wine – too much alcohol leads to the dreaded droop.
Another natural treatment for erectile dysfunction to consider would be vitamin E. This is a vitamin that has been linked to chronic diseases in the past due to the antioxidant effects of this vitamin. Considering ED could be a manifestation of another chronic condition, it makes sense that vitamin E may have a role in reducing the symptoms of the disease. As a person ages, it is natural for the body to undergo more oxidative stress and damage as cells do not function as well as they once did. Rats who were given supplemental vitamin E were found to have reduced levels of oxidative damage to their tissues and had levels of NO and other factors that help induce an erection more similar to younger rats compared to rats without vitamin E supplementation. If patients incorporate vitamin E into their vitamins and dietary supplements for ED, their ED should improve. [9]
Erectile dysfunction supplements and other natural remedies have long been used in Chinese, African and other cultures. But unlike prescription medications for erectile dysfunction, such as sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis, Adcirca) and avanafil (Stendra), erectile dysfunction herbs and supplements haven't been well-studied or tested. Some can cause side effects or interact with other medications. And the amount of the active ingredient can vary greatly from product to product.
