The Science: Male rats with damaged penile nerves had better erectile responses after they were given large doses of purified icariin, but as of yet no one has done the experiments to see whether the compound works in humans. Still, as far as the herb goes, it doesn’t really matter: horny goat weed doesn’t contain enough icariin to get even the smallest rise out of a rat.

Acupuncture. Acupuncture has been used for centuries to treat ED and impotence in China. A recent review of studies on acupuncture for erectile dysfunction was published in the British Journal of Urology International. After reviewing four studies, the authors concluded that there was not sufficient evidence to say that acupuncture worked. However, some experts believe it's worth trying. "Acupuncture can work," says Gilbert. "It probably works best to treat the psychological component of ED. There is very little downside to trying it."
ED may occur at any age, but tends to have a greater psychological effect when it occurs in midlife. ED invokes stress related to midlife intimacy and the physiological realities of aging. Although the prevalence of ED increases with age, it is not an inevitable consequence of aging. Rather, ED becomes more prevalent as men grow older because of its relationship with various age-related diseases. Several studies have found that age is an independent risk factor for severe ED, even after adjustment for other age-related diseases. The aging male requires more penile stimulation; it takes longer to get an erection and the erection may not be hard enough for vaginal penetration. Also, it takes more time to reach ejaculation in elderly individuals. Absence of sexual interest in the partners of older men can lead to ED simply by the man not receiving sufficient direct penile stimulation. Testosterone replacement therapy for aging men has become a topic for discussion among health care providers. There are no established norms for testosterone levels in aging men. Studies in healthy men show that testosterone levels, particularly free bioactive testosterone levels, decline with age although there is considerable interindividual variation. The percentage of men who actually become ‘testosterone deficient’ is unknown. The diagnosis of androgen deficiency in aging men is associated with a wider range of symptoms than a mere impact on hormone levels per se. If the patient has no clinical signs of an androgen deficiency, testosterone replacement therapy will have no clinical effect.

If you bike a lot and have a very narrow saddle on your bicycle, consider switching to a "no-nose seat" which is wider at the back than a conventional saddle, allowing more of your weight to be distributed to the sitting bones. Make sure the seat is level or angled slightly downward and at a height that allows your knee to be just slightly bent at the bottom of the pedal cycle. Raising the handlebars on your bike so that you're sitting upright may also help.
However, you might actually be better off going one step back in the chain reaction and taking an L-citrulline supplement. While your body converts L-arginine to nitric oxide, it also metabolizes it too fast when the amino acid is taken in an oral supplement, according to a 2011 study from the University of Foggia in Italy. L-citrulline, which the body converts to L-arginine, is actually a better option to follow the same metabolic pathway and serve as a treatment for ED, the same study found.
While the rationale behind why it would work is airtight, the research on arginine’s actual effect on erectile dysfunction is slim, points out Charles Walker, M.D., assistant professor of urology and cofounder of the Cardiovascular and Sexual Health clinic at Yale University. But given its solid safety profile, minimal side effects, and potential benefit on heart disease, it’s worth a try, he adds, especially when taken in conjunction with other herbs on this list, which studies have shown can be more effective.
While these side effects mainly create discomfort, some individuals are at risk for more serious, even life-threatening reactions to these drugs. Some men have reported fainting after taking impotence medications, and priapism (a painful condition involving an erection that does not subside after more than four hours) has also occurred as an effect of impotence drugs. This condition can lead to permanent nerve damage; injectable drugs may also cause irreversible damage to the penis if used incorrectly.
The informal conversations were held with the specialist resource users and other knowledgeable people on particular ailments. The meeting places were the gardens, women group meetings, at their homes, and any other places convenient to them. Through conversations, the sources of knowledge of the healers on medicinal plants, the medicinal plants used and changes in the availability of medicinal plants were established. Those who were more knowledgeable were later followed and interviewed further especially the TBAs, and some knowledgeable men healers. Focused discussions were held with them later for formal recording. In some instances, young mothers were visited too. This was done to verify the information gathered and the spread of the indigenous knowledge (IK) in reproductive health care among the different reproductive groups particularly on ED management.
Arginine. The amino acid L-arginine, which occurs naturally in food, boosts the body's production of nitric oxide, a compound that facilitates erections by dilating blood vessels in the penis. Studies examining L-arginine's effectiveness against impotence have yielded mixed results. A 1999 trial published in the online journal BJU International found that high doses of L-arginine can help improve sexual function, but only in men with abnormal nitric oxide metabolism, such as that associated with cardiovascular disease. In another study, published in 2003 in the Journal of Sex & Marital Therapy, Bulgarian scientists reported that ED sufferers who took L-arginine along with the pine extract pycnogenol saw major improvements in sexual function with no side effects. Arginine can be helpful, says Geo Espinosa, ND, director of the Integrative Urological Center at NYU Langone Medical Center. Espinosa says that men with known cardiovascular problems should take it only with a doctor's supervision; L-arginine can interact with some medications.
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.
The Institute of Medicine recommends cumulative daily vitamin D intake of 600 international units (IU) for adults between 18 and 70 years of age , and 800 IU for those over 80. A 3oz serving of salmon contains about 450IU, while an 8oz. glass of milk only has about 100IU. Low vitamin D levels may be an independent, potentially modifiable risk for ED, so it’s worth taking Vitamin D supplements for your “D.” However, keep your daily vitamin D supplement intake below 4,000IU, as too much vitamin D can be toxic.
Ashwagandha (Withania somnifera), used widely in Ayurvedic medicine, holds a similar role to that of ginseng in Chinese medicine. Though unrelated to ginseng, it appears to share similar properties and actions. Ayurveda considers this herb to be a rasayana, or particularly powerful rejuvenative. The name ashwagandha means “like a horse,” connoting that it is regarded as a premier sexual tonic.
Yohimbe. Before Viagra and the other prescription erectile dysfunction drugs became available, doctors sometimes prescribed a derivative of the herb yohimbe (yohimbine hydrochloride) to their patients suffering from ED. But experts say the medication is not particularly effective, and it can cause jitteriness and other problems. "It's not a great drug," says McCullough. "And I suspect the herb is not as potent as the pharmaceutical version." What's more, evidence shows that yohimbe is associated with high blood pressure, anxiety, headache, and other health problems. Experts discourage its use.
Research is mixed on the effectiveness of acupuncture as an erectile dysfunction cure, but one study published in November 2013 in the Journal of Alternative and Complementary Medicine found that acupuncture can be beneficial for men experiencing erectile dysfunction as a side effect of antidepressants, including selective serotonin reuptake inhibitors (SSRIs) and serotonin noradrenaline reuptake inhibitors (SNRIs).
A recent study tested whether ginseng extract would influence exercise-induced muscle damage and inflammation responses. Male college students took either ginseng or a placebo, and then performed a high-intensity uphill treadmill running task. In those taking ginseng, inflammation markers were significantly decreased during recovery, suggesting that ginseng could reduce exercise-induced muscle damage.
The Claim: If you squint and have an excellent imagination, mature ginseng roots vaguely resemble a human body. That ties into folk ideas for finding medicines–in this case, the idea that a plant that looks like a person must contain materials that help sick people. Ginseng was traditionally used as a tonic to treat erectile dysfunction and low sexual drive in men (as well as many other complaints).
Consider this: penicillin, the first successful antibiotic, was derived from molds that inhibit bacterial growth. Scientists had to figure out why the molds slowed bacteria, and refine the active ingredients. Using herbal supplements is somewhat like putting mold on a wound. It might help, a little, but it’s certainly not going to help as much as using penicillin.
Tribulus terrestris (6): this plant has long been used as a folk medicine in Eastern Europe and Bulgaria for sexual deficiency (5). The properties of this powerful ingredient have been associated with an increase in sperm production, sexual endurance, and testosterone levels. Also known as puncture vine, this herb has gained popularity over the past few years. Since testosterone plays a huge role for men, the addition of this herb can prove to be very beneficial. It is not a hormone as some believe. It is said that Tribulus terrestris can also help build muscle and strength, which enhances performance (5,7).
The causes of ED are varies from one individual to another. For whatever cause, since an erection requires a precise sequence of events, ED can occur when any of the events is disrupted. This sequence includes nerve impulses in the brain, spinal column, and area around the penis, and response in muscles, fibrous tissues, veins, and arteries in and near the corpora cavernosa23. Thus, ED causes reported include, damage to nerves, arteries, smooth muscles, and fibrous tissues. These are often as a result of diseases, such as diabetes, kidney disease, chronic alcoholism, multiple sclerosis, atherosclerosis, vascular disease, and neurologic diseases that account for about 70 percent of ED cases23. NIH23 reported that between 35 and 50 percent of men with diabetes experience ED. NIH23 further reported that the usage of many common medicines such as blood pressure drugs, antihistamines, antidepressants, tranquilizers, appetite suppressants, and cimetidine (an ulcer drug) can produce ED as a side effect. Nevertheless, psychological factors such as stress, anxiety, guilt, depression, low self-esteem, and fear of sexual failure cause 10 to 20 percent of ED cases. In addition, men with a physical cause for ED frequently experience the same sort of psychological reactions (stress, anxiety, guilt, depression)23. Other possible causes are smoking, which affects blood flow in veins and arteries, and hormonal abnormalities, such as not enough testosterone23.
A number of nonprescription products claim to be herbal forms of Viagra. Some of these products contain unknown amounts of ingredients similar to those in prescription medications, which can cause dangerous side effects. Some actually contain the real drug, which should be given by prescription only. Although the Food and Drug Administration has banned many of these products, some potentially dangerous erectile dysfunction remedies remain on the market.
