Most importantly, herbal supplements are not well regulated in the United States.  Studies have shown that 40-50% of herbal supplements do not even contain the supposed main ingredient, and many contain substances that are not listed which may have dangerous side effects2.  Another study found that over two thirds of the products tested had substituted other plant species for the plants listed on the label, and a third of products also contained other fillers or contaminants3.  A study by the New York State Attorney General of herbal products sold at GNC, Target, Walgreens, and Walmart found that four out of every five products didn’t contain the ingredient they claimed!  Fourteen US states and territories have petitioned Congress to regulate the herbal supplements industry.

A daily dose of niacin improves erectile function, particularly in men with high cholesterol, according to a 2011 study in The Journal of Sexual Medicine. The vitamin helps increase blood flow and reduce inflammation—one of the underlying causes of both high cholesterol and erectile dysfunction. “Vitamin B3 is also used to make sex hormones and other important chemical-signal molecules,” says Fisch. Like many of the others on our list, this tablet is most powerful when taken in conjunction with others: A cocktail of propionyl, L-carnitine, L-arginine, and niacin taken for three months improved 40% of erections in a study from researchers at Sapienza University of Rome in Italy.
If you can't take one of these oral medications, your physician may have you try Caverject (alprostadil for injection), a hormone that you inject into your penis using a fine needle, or Muse (alprostadil urogenital), a tiny suppository that you insert into the tip of the penis. Both of these will bring on an erection within five to 15 minutes without sexual stimulation.

If the condition is not treated immediately, it can lead to scarring and permanent erectile dysfunction. Long lasting erections may associated with pain due to the lack of oxygen to the penis because the penis is filled with oxygen deplete venous blood. Peyronie’s disease (a scarring of some of the deep tissues in the penis) can have a localized area of pain but usually involves a lump and some deviation of the erection to the affected side.

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.
Peanuts contain a trove the amino acid L-arginine, which is one of the building blocks of nitric oxide, which aids your efforts under the covers. They also help reduce cholesterol levels. The less cholesterol you have in your system, the easier it is for blood to circulate throughout your body and down, which can help you maintain a firmer erection longer.
"Evidence that foods can help with ED is probably related to a vascular connection," says Firouz Daneshgari, MD, professor and chairman of the department of urology at Case Western Reserve University School of Medicine and University Hospitals Case Medical Center in Cleveland. "Erectile problems are usually due to not having a good blood supply to the penis, so foods that are good for your vascular system may also help prevent ED." Should you eat more of the foods containing these key nutrients?
Tufan herbal ED pills dilate blood vessels and make nerves and tissues of male genital region stronger. Dilated blood vessels supply more blood on arousal and which allows tissues to absorb blood and cause erections. Tufan herbal ED pills make tissues stronger so that these absorb more blood and grow more in size and get stiffer, stronger tissues provided by these best ED pills cause rock hard erections in a flash. These benefits provided by Tufan herbal ED pills resolve problem of slow, soft and weak erections and allow a male to gain quick, stronger and harder erections to provide natural ED treatment.
Conventional impotence treatments typically involve the use of medications which work with the body's natural chemistry in order to promote the ability to have an erection. Oral medications such as Viagra, Levitra and Cialis are commonly prescribed; injectable medications such as the impotence drug Caverject are also used for treating male impotence.

Yohimbine. This chemical is found in the bark of an African tree called yohimbe. It has been used as a male aphrodisiac in Africa, and under medical supervision it has been used as a prescription drug to treat ED. Supplements made from yohimbe bark are also available without a prescription, but they can be life-threatening if used at high doses, according to the Natural Medicines Comprehensive Database. The supplement can interact in a harmful way with certain drugs, such as blood pressure medications, and should be avoided by anyone with liver, kidney, heart, or diabetes problems or problems with anxiety or depression. Like DHEA, yohimbine should not be taken without a doctor's supervision.
There is no single cause for erectile dysfunction. Achieving an erection involves a complex series of physiological events; in order for an erection to occur, the body is required to coordinate nervous system responses with tactile sensations, emotional triggers, and signals from certain hormones. If any of these events are disrupted, impotence is likely to occur.
By far the most common cause of ED is vascular dysfunction. When the arteries that supply the penis with blood to achieve and maintain an erection are blocked or hardened, or the lining of these arteries are damaged, blood flow is reduced. Vascular dysfunction not only affects the small arteries of the penis, but the larger coronary arteries of the heart too. Astute doctors now recognize that ED may actually be an early warning sign of impending cardiovascular disease, showing up several years before a cardiovascular event like a heart attack or stroke.2 To maintain healthy vascular function, and in turn, normal erectile function, consider these supplements:
The article discusses erectile dysfunction (ED) with the special emphasis on epidemiology, as well as the currently available medical treatments. Describing treatment methods authors paid special attention to natural therapies (as Panax ginseng, Tribulus terrestris, Vaccinium macrocarpon), because taking into consideration their safety profile, they appear to be an important alternative to therapies with synthetic molecules. From substances of natural origin, extract from the fruit of Tribulus terrestris ranks itself high on in collation at the end. The results of most clinical trials and experiments clearly demonstrate its effectiveness in improving sexual function in men.
Coffee / Caffeine.  A study found that men who consume the equivalent of 2-3 cups of coffee per day have a 39% lower incidence of erectile dysfunction than men who do not drink coffee11. Although the study showed a correlation between drinking coffee and  a lowered incidence of ED, it did not demonstrate a causative relationship.  Note that consuming larger amounts of coffee can raise stress and adrenaline levels, and can actually contribute to ED.
I mentioned taking herbs and supplements to treat erectile dysfunction, so I want to add a note of caution about using so-called “natural male enhancement” pills. The Food and Drug Administration (FDA) recalls dozens (if not hundreds) of these products each year for containing the active ingredient in medications used to treat ED. When you buy those products from the internet, or even from a retail store, you have no real way of knowing what you’re ingesting. The active ingredient in drugs like Viagra, Cialis, and Levitra can negatively interact with other medications, so it’s essential that you take them with medical supervision.
The Aztecs referred to avocados as testicles because of their scrotum-like appearance. They were onto something. The green fruit is rich in potassium, vitamin B6 and vitamin E, nutrients that have been associated with increased libido. Plus, avocados’ good monounsaturated fats protect your heart and boost circulation, while their abundant minerals and carotenoids supply energy and stamina. For some creative ways to consume the fruit, check out our 10 avocado recipes for weight loss.
There are many different body parts that play an important role for a man to get and maintain an erection during sexual intercourse. Beyond the physical causes that can lead to ED, it has been reported that 20% of ED is related to psychological causes.2 With so many possibilities leading to erectile dysfunction, it becomes particularly important to find a specialist who can correctly diagnosis the direct cause of your ED and find a treatment option that is right for you.
If seafood isn’t your thing — or the Casanova Breakfast Plan doesn’t work with your budget — know that fortified breakfast cereals are also good sources of B12. According to the USDA, healthy cereals such as Kellogg’s All-Bran, Special K, Smart Start and Whole Grain Total provide a full day’s allowance. Check the nutrition facts and opt for whole grains, which can help lower cholesterol levels. Having high cholesterol can lead to atherosclerosis, or clogged and constricted arteries, which inhibits blood flow. That’s dangerous for your heart, but guess which artery-rich organ you’ll probably notice it in first?
When lifestyle changes alone don’t work, drug therapy (Viagra®, Cialis®, Levitra®, etc.) is normally the next step. Most of these medications work similarly to enhance a natural chemical in your body that relaxes the muscles in your penis. The goal of this medication is to increase your response to sexual stimulation by increasing the blood flow in your penis allowing you to get an erection.22

A study published in May 2014 in The Journal of Sexual Medicine found that some men can reverse erectile dysfunction with healthy lifestyle changes, such as exercise, weight loss, a varied diet, and good sleep. The Australian researchers also showed that even if erectile dysfunction medication is required, it's likely to be more effective if you implement these healthy lifestyle changes.
