ED can be caused by a handful of things, but one thing’s for sure: You need a healthy supply of the neurotransmitter nitric oxide (NO) to get and maintain an erection. NO is produced in nerve tissue and helps jolt your Johnson by relaxing the smooth muscle so blood can fill the penis. After the initial release of NO, your body releases a cascade of chemicals—including more of the neurotransmitter—to help keep you hard and happy, according to a study in the Proceedings of the National Academy of Sciences.
It hits where it hurts the most – your member. Erectile dysfunction or ED is a spoiler in bed and can shatter your ego irreparably. ED, also called impotence, is the inability of a man to achieve and maintain an erection sufficient to permit satisfactory sexual intercourse.1 Men who cannot get or maintain an erection that lasts long enough or is rigid enough to complete sexual intercourse are considered to have erectile dysfunction.

Penile vibratory stimulator is a battery operated device with oscillating discs that can provide excitation of afferent penile nerves at various regulated frequency and amplitudes. PVS has been utilised to activate the ejaculatory reflex for patients with spinal cord injury above T10 seeking to collect retrogradely ejaculated semen in fertility treatment (10). The Viberect is a vibratory stimulation handheld device approved by FDA for treatment of ED. It is clamp-shaped with two oscillating discs facing each other near the tips, and the glans penis is placed between the two oscillating discs to receive concurrent dorsal and ventral stimulation at adjustable frequencies and amplitudes.

A 2000 study conducted at the Institute of Sexology in (where else?) Paris found that muira puama, a Brazilian shrub traditionally used in South African folk medicine as an aphrodisiac, increased libido in a majority of men who complained of impotence and a lack of desire. Other studies show this happy-making herb also counteracts chronic stress, depression and nervous exhaustion.
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.

According to the Cleveland Clinic, “because erectile dysfunction is caused by a complex set of psychosocial, neurologic, and vascular factors, a specific cause in a patient may remain ambiguous.” The root causes are often related to a blockage or dysfunction of blood vessels. For example, ED can be due to conditions like atherosclerosis or diabetes, hormonal imbalances or problems related to mental health. It’s been found that common causes typically include one or more of the following factors: (2)
If you’ve been to the health food store lately, you’ve seen shelves lined with vitamins and “organic” supplements, each claiming to boost immunity, revitalize organ function, or “promote health.” And it’s working. Supplements are currently a $30 billion industry in the US, with more than 90,000 products on the market, and vitamin use is on the rise. In fact, a recent survey in Journal of American Medicine Association showed that “52% of US adults reported use of at least 1 supplement product.”

ED is often treated with psychotherapy, behavior modification techniques, oral medications, locally injected drugs, vacuum devices, and sometimes even surgically implanted devices. In rare cases, surgery of the blood vessels may be necessary. In most cases, even when a physical cause is identified, emotional or psychological factors play a role as well.

Persons with metabolic syndrome can be identified by a distinct pattern of abdominal obesity (waist circumference >40 inches in men), atherogenic dyslipidemia (triglycerides ≥150 mg per 100 ml, HDL <40 mg per 100 ml, small LDL particles and normal or slightly elevated LDL), hypertension (≥130/85 mm Hg), insulin resistance (fasting blood glucose ≥10 0 mg per 100 ml), and elevated levels of prothrombotic and proinflammatory markers. Metabolic syndrome and insulin resistance are closely linked to ED. In one recently conducted study of 120 men with ED and no evidence of diabetes, 40% of patients fulfilled strict criteria for metabolic syndrome, and 73% were insulin resistant.12
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:

Honey, unlike table sugar, is packed with beneficial compounds like quercetin, which has been shown to aid athletic endurance and ward off depression.. Honey also has a less dramatic impact on your blood-sugar levels than regular sugar, so it won’t send your body into fat-storage mode the way the white stuff can. Try adding some honey to your afternoon tea or morning bowl of oatmeal, but don’t go overboard; the sweet nectar has 17 g of sugar and 64 calories per tablespoon, so too much honey can make you heavy, rather than horny.
Deer velvet is a covering found on the growing bone and cartilage of deer’s antlers. In Eastern medicine, deer velvet is sought after for its Chinese medicinal properties which include boosting one’s endurance and improving one’s immunity. People have also used deer velvet as an aphrodisiac or to treat ED. The randomized double-blind placebo-controlled study on deer velvet by Conaglen et al. (31), no benefit but this study was underpowered involving healthy participants with no sexual dysfunction.

According to Daneshgari, "Your best bet is to eat a healthy diet that is good for your heart and your circulation." Other foods that are good for your circulation include cranberries, apples, peanuts, onions, tea, and red wine. Chances are, if you take good care of your vascular health, you will avoid many of the common causes of erectile dysfunction.
In fact, one common reason many younger men visit their doctor is to get erectile dysfunction medication. Often, men with erectile dysfunction suffer with diabetes or heart disease, or may be sedentary or obese, but they don’t realize the impact of these health conditions on sexual function. Along with erectile dysfunction treatment, the doctor may recommend managing the illness, being more physically active, or losing weight.
