Researchers in London set out to find out if the claims about Yohimbe were true. Could the bark of a tree actually increase libido and improve impotence? They performed a double-blind trial using yohimbine for the treatment of erection inadequacy. Men, aged 18-70 years, seeking help for the secondary erection inadequacy for 6 months or longer, took part in the trial. None of the participants had any serious psychiatric disease, hypertension or liver insufficiency. Half of the men were given 5.4mg of yohimbine, the other half a placebo, for 8 weeks. Patients were assessed in 4-week intervals. After 8 weeks of treatment, 37 percent said they had good erections, as compared to only 13% in the placebo group. After the 8-week treatment, the placebo group was given the yohimbine as well, results for improved stimulated erection after the second 8-week trial increased to a total of 42 percent overall.

Yohimbe bark is an herbal supplement. Its species name is Pausinystalia yohimbe. Yohimbe comes from the bark of the evergreen Corynanthe yohimbe tree, which is in the plant family called Rubiaceae. The active ingredient in yohimbe, called yohimbine, is also used to make certain medications. Civilizations in Western Africa have used it for centuries. Today it’s studied for its ability to help treat conditions including erectile dysfunction/impotence, diabetes, depression, hypotension, and overuse of certain medications.
Instead of injecting a medicine, some men insert a suppository of alprostadil into the urethra. A suppository is a solid piece of medicine that you insert into your body where it dissolves. A health care professional will prescribe a prefilled applicator for you to insert the pellet about an inch into your urethra. An erection will begin within 8 to 10 minutes and may last 30 to 60 minutes.
With the erectile dysfunction (ED) market expected to reach 3.4 billion dollars (USD) by 2019, this is a lucrative area to invest in, and not much grabs the attention of a guy watching a commercial during a Monday night football game than the promise to easily cure this problem with one pill as needed.  But is this the answer for everyone?  What causes ED?  For the guy with no apparent risk factors like depression or diabetes, hypothyroidism, injury or stress issues, erectile dysfunction or loss of libido (which don’t necessarily go hand in hand) can be confusing and frustrating for a guy as well as his partner.
In the 18th century, Spain embraced the Age of Enlightenment, directing the beacons of thought to all endeavors. But while Spain was not as advanced as France, Britain, Germany, or America, its new political thinking led to the revocation of most of the historical rights and privileges of the sub-kingdoms that comprised the Spanish Crown. Those changes, in turn, allowed for the freedom of inquiry that was so needed for medical discovery, among others.

Alprostadil self-injection. With this method, you use a fine needle to inject alprostadil (Caverject Impulse, Edex) into the base or side of your penis. In some cases, medications generally used for other conditions are used for penile injections on their own or in combination. Examples include papaverine, alprostadil and phentolamine. Often these combination medications are known as bimix (if two medications are included) or trimix (if three are included).
Knowing about your history of ED will help your health provider learn if your problems are because of your desire for sex, erection function, ejaculation, or orgasm (climax). Some of these questions may seem private or even embarrassing. However, be assured that your doctor is a professional and your honest answers will help find the cause and best treatment for you.
In the present study zinc caused an elevation of T. This showed an increase from 2.39 to 8.21 ng/dl after two weeks of zinc treatment. This elevated T level may have contributed to the increase in number of penile thrusting (from 26.5 to 52.8) observed. Supplementation with 459 μmol/day of zinc for three months, in marginally zinc deficient healthy elderly men, has been shown to increase the levels of serum T from 8.3 to 16 ng/dl.[25] Laboratory experiments indicate that the nitric oxide erectile pathway is T dependent.[26] Many studies using animal models have confirmed that T is important in modulating the central and peripheral regulation of erectile dysfunction. T deprivation has a negative impact on the structure of penile tissues and erectile nerves.[27] Thus, elevated T levels subsequent to zinc supplementation may increase the sexual competence via rigid and sustained erection. This may promote greater tactile stimulation of the penis due to increased contact with vagina.[25]
This study was designed to test the hypothesis that hydrochlorothiazide a diuretic used to treat hypertension depletes body zinc and thereby cause sexual dysfunction. Serum zinc and sexual dysfunction were measured in 39 middle aged hypertensive men who had been taking hydrochlorothiazide in average daily doses of between 25 and 50 mg daily for at least six months, and a control group of 27 unmedicated middle aged normotensive men. The medicated group had a higher incidence of sexual dysfunction (56 pc) as compared to 11 pc in the control group. The use of hydrochlorothiazide did affect serum zinc levels significantly in 20 patients. Sexual dysfunction occurred more often in older and overweight patients (p < 0.004). Three of the normotensive men experienced sexual dysfunction probably related to old age. Twenty two of the 39 on hydrochlorothiazide and experiencing sexual dysfunction were divided into two groups of 11 patients. Bloods were taken from the 27 normotensive and 22 hypertensive men receiving hydrochlorothiazide for the analyses of zinc. Subsequently one group of the patients were supplemented with zinc 500 mg daily for 30 days while the other group was supplemented with magnesium chloride 1 g daily for 30 days. The normotensive men were not treated. After 30 days, bloods were again taken from the three groups of analyses for zinc and magnesium. Serum zinc was significantly decreased (p < 0.05) by hydrochlorothiazide and a non significant decrease in serum magnesium (p = ns) was observed. After supplementation with zinc, the serum zinc levels returned to normal only in eight patients. There was improvement in the symptoms of sexual dysfunction in five patients. Two patients gained weight. Hydrochlorothiazide decreased serum zinc levels (p < 0.05) and was unchanged with magnesium supplementation but the serum magnesium returned to normal values. Improvement of symptoms of sexual dysfunction was positive in one patient. This study shows that low serum zinc levels may be associated with sexual dysfunction but the definitive role of zinc in the pathogenesis of sexual dysfunction will remain controversial.
A study from the University of the West in the United Kingdom found that pelvic exercises helped 40 percent of men with ED regain normal erectile function. They also helped an additional 33.5 percent significantly improve erectile function. Additional research suggests pelvic muscle training may be helpful for treating ED as well as other pelvic health issues.
Low-intensity extracorporeal shock wave therapy has been proposed as a new non-invasive treatment for erectile dysfunction caused by problems with blood vessels. Shock wave therapy machines are now available in some medical practices in Australia. Although there is some evidence that it may help a proportion of men with erectile dysfunction, more research is needed before clear recommendations on its use can be made.
Whether you’re looking to bulk up, or are just concerned about having enough protein to keep your body strong and healthy, zinc is an absolute must have! When we eat protein, it gets broken down by the body into amino acids, and then resynthesized into the different proteins needed by the body, and zinc is a vital part of this process. So even if you are eating lots of protein, without zinc you won’t be able to use it properly!
The men started with a daily dose of 500 mg, to make sure they had no adverse side effects, then increased to 1,000 mg and then 1,500 mg. However, Men's Health warns that according to the US's Baylor College of Medicine urologist Larry Lipschultz, not only do niacin supplements often contain less of what the bottle says, "but ED can also be a precursor to heart disease -- a condition you should treat with your doctor's advice."

Hypercholesterolemia (high cholesterol) is one of the main risk factors in the development of atherosclerosis, a condition that with the development of statins over the last 20 years has become more treatable, but not without consequences. Statins have been shown to reduce the incidence of cardiovascular events by 25–40%, yet this reduction is no big deal, especially considering that many patients need additional therapy to reach more optimal lipid levels and prevent cardiovascular events.
Not only will regular exercise burn calories and lower stress, it may lower your risk of ED. Before you start working out, check with your doctor about the best program for you. Think of exercises you're likely to enjoy and will want to continue on a daily basis, whether it's 30 minutes in the morning on a stationary bike while watching the news, a kick-boxing class, or a brisk after-dinner walk around the neighborhood with a friend.

Does diabetes cause erectile dysfunction? Diabetes can lead to lower levels of testosterone, and this can result in erectile dysfunction. Controlling blood sugar levels, maintaining a healthy weight, getting exercise, and reducing stress are all ways of reducing this problem. Hormone therapy, Viagra, and counseling are some ways that medicine can help. Read now

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

Researchers found that this compound, delivering 6mg of yohimbine HCL and 3.25g of L-arginine, significantly improved erectile function in those with mild-to-moderate ED. [15] L-arginine is an amino acid that acts as a precursor to and plays a critical role in nitric oxide production. Yohimbine paired with a compound encouraging nitric oxide production may be the perfect combination for significantly decreasing or eliminating symptoms of erectile dysfunction.

L-arginine, or arginine, is an amino acid found in red meat, poultry, fish, and dairy products that helps expand blood vessels and increase blood flow. “The body uses this semi-essential amino acid as the primary building block for nitric oxide,” explains Harry Fisch, M.D., clinical professor of urology and reproductive medicine at Weill Cornell Medical College/New York Presbyterian Hospital.


Latest research studies highlighted that a daily dose of Vitamin B3 or Niacin brings a drastic improvement in the erectile function of men dealing with the problem of high cholesterol. This result reveals that about 80 men, who consumed Niacin and started the study with either moderate or severe level of erectile dysfunction highlighted a significant improvement in the ability of maintaining an erection.


Niacin -- with or without the addition of drugs to treat impotence -- poses serious health risks, including stomach ulcers and liver damage. If you have Type 2 diabetes, taking niacin could cause drastic elevations in your blood sugar levels. Less serious side effects include stomach upset and skin flushes -- your face and chest turn red and your skin itches, tingles or burns. You can purchase niacin without a prescription, but some over-the-counter formulas -- no-flush varieties that contain niacinamide -- will unlikely help lower your cholesterol.
Response to yohimbine was not dependent on patient age. Patients who showed a positive response had fewer medical risk factors overall, although the small number of patients was not large enough to provide statistical significance. The positive clinical response was verified subjectively both by the formal questionnaire and by the in-office clinical encounter. The positive response was verified objectively by measuring nocturnal penile tumescence and rigidity with the RigiScan™ home monitor. The trend of the baseline penile erectile response was better in the responders, suggesting that use of yohimbine might be more effective in patients who have less severe erectile dysfunction. Some authors have questioned the effect of yohimbine on penile activity, but either inadequate doses of yohimbine were used or only tumescence was measured,21,32 often in an office setting where anxiety and embarrassment might affect results.
You may find that using a vacuum device requires some practice or adjustment. Using the device may make your penis feel cold or numb and have a purple color. You also may have bruising on your penis. However, the bruises are most often painless and disappear in a few days. Vacuum devices may weaken ejaculation but, in most cases, the devices do not affect the pleasure of climax, or orgasm.

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.


Vidal and her team looked at self-reported physical activity among 300 men, and then categorized them into categories: sedentary, mildly active, moderately active, and highly active. These men also reported their levels of sexual function, including their ability to have an erection and orgasm, as well as the quality and frequency of their erections and overall sexual function.
Responders tended to have consistently higher scores compared with nonresponders. For nonresponders, none of the scores was significantly different when comparing baseline scores with either of the yohimbine doses. However, a trend toward an improved total questionnaire score was noted from baseline to the 5.4 mg tid dose (P=0.083). For responders, a significant increase in the Florida Sexual History Questionnaire total score was observed from baseline to the time the 5.4-mg tid dose was administered (P=0.021). A trend closely approaching statistical significance (P=0.055) was noted from baseline to the administration of the 10.8 mg tid dose of yohimbine. Inspection of changes in the individual items revealed that responders reported significantly greater frequency of vaginal penetration with both the 5.4- and 10.8-mg doses of yohimbine tid compared with baseline (P=0.010 and P=0.010, respectively). Participants also noted less difficulty obtaining an erection for sexual intercourse while taking 10.8 mg of the drug compared with baseline (P=0.011). Responders reported having significantly less difficulty maintaining an erection for sexual intercourse compared with baseline with both the 5.4-mg tid dose (P=0.049) and the 10.8-mg tid dose (P<0.001). Responders also reported significantly greater penile firmness and rigidity before intercourse or masturbation in both treatment conditions compared with baseline (P=0.02 for the 5.4-mg tid dose and P=0.013 for the 10.8-mg tid dose).

The concentration of yohimbine in commercial supplements may vary from one manufacturer to another. A chemical analysis conducted on 26 brands of yohimbe supplement shows that nine products contain no yohimbe extract at all, while eight products contain only small amounts of yohimbine — approximately 0.1 to 1 parts per million (ppm), which is significantly low compared to 7,089 ppm yohimbine in an authentic yohimbe bark.3

This African tree bark extract sends blood flow to the genitals, said herbalist Ed Smith, a founding member of the American Herbalists Guild, who adds a warning that Yohimbe can cause nervousness and raise already-existing high blood pressure (so avoid taking it if you have heart or kidney disease), and can also negatively interact with antidepressants.


In a recent study, moderate-intensity exercise such as walking briskly and light cycling was shown to boost mood for up to 12 hours. Exercising every day might be best to lift your mood, but strive for at least 5 days a week. Another study showed exercise can improve your body image, regardless of body weight or shape. And feeling good about your body is a great start toward making the bedroom a happier place.
Research suggests that drinking alcohol may play a part in erectile problems. One study that considered the prevalence of ED among people diagnosed with alcohol dependence syndrome found that heavy drinkers were more likely to experience sexual dysfunction. Experts also believe that the depressant effect of alcohol can inhibit sexual response and even suppress libido in some people.
I recently treated a young twenty-something man with a primary complaint of erectile dysfunction. When he started to notice this issue, he attempted to treat it by performing lots of kegels. (If you haven’t heard of kegel exercises, they’re done by repeatedly contracting and relaxing the muscles that form part of the pelvic floor, as if you were trying to stop peeing mid-stream.) I found this man’s story interesting because, as we discovered, in his case the kegels actually did more harm than good. We found that once he stopped kegeling and allowed his pelvic muscles to relax, his erections became stronger and he was able to ejaculate without any issues.
Obesity is a state of chronic oxidative stress and inflammation (38). The increased oxidative stress associated with obesity may increase free radical formation, which could quench and deactivate nitric oxide, reducing its availability for target cells. Weight loss programs with dietary modifications and increased physical activity may lead to reduced oxidative stress associated with improved nitric oxide availability (39). As impaired nitric oxide activity appears to play an important role in the pathogenesis of erectile dysfunction (40), improved nitric oxide availability associated with weight loss may be implicated in the amelioration of erectile function in our series of obese men. A reduced CRP level due to sustained lifestyle changes may have contributed to amelioration of erectile function after treatment. Levels of CRP correlate significantly with reduced nitric oxide availability (41) and increasing severity of penile vascular disease as measured by penile Doppler (42). Moreover, consistent findings support a predictive role of CRP and IL-6 for cardiovascular events in different populations (43), while IL-8 is a potent chemoattractant (44).
Yes, niacin is good for erectile dysfunction. Vitamin B3 or Niacin acts as a powerful agent to improve the condition of erectile dysfunction and a research study conducted in a medical center of Hong Kong confirmed that Niacin supplementation has resulted in the increase of blood flow across the pelvic region in men. In addition, researchers have further confirmed that the Vitamin comes with the ability to unclog various harmful fats collected in the artery region.
While eating magnesium-rich foods or taking a magnesium supplement at the proper dosage is safe for most men, the mineral can interfere or interact with some medications. Discuss the benefits and risks of altering your daily magnesium intake with your doctor, particularly if you take blood pressure medications, diuretics, diabetes medications or antibiotics. Men diagnosed with erectile dysfunction often require changes in other minerals and vitamins or even prescription medication. Ensuring a proper daily intake of magnesium may help maintain healthy erectile function, but magnesium alone is unlikely to cause a significant reduction in ED symptoms. Magnesium levels can also be affected by excess weight, chronic stress and excessive amounts of alcohol. These factors may also be partially responsible for erectile problems.

The sunshine vitamin will brighten things up in the bedroom. In a recent study published in the Journal of Sexual Medicine, Italian researchers found that of 143 men with erectile dysfunction, 80% had less-than-optimal levels of D, and the men with severe ED had, on average, a 24% lower level of D than with a milder condition. They theorize that low levels of D damage blood vessels and lead to a shortage of nitric oxide.
Many prostate problems, including cancer, are linked to zinc deficiency, and when the Chicago Center for the Study of Prostatic Diseases gave 50 to 100mg of zinc daily to patients suffering from infection of the prostate, 70 per cent of cases showed improvement. Zinc levels decline with age and men over fifty can fight impotency and prostate enlargement by taking zinc supplements.
Niacin or Vitamin B3 has proved to be helpful in improving both lipid levels and cholesterol among patients suffering from the problem of atherosclerosis i.e. accumulation of waste fats across the walls of the human blood vessel. Because of this, Niacin is helpful in the treatment of erectile dysfunction, as ED and atherosclerosis have more or less similar causes.
With an inflatable implant, fluid-filled cylinders are placed lengthwise in the penis. Tubing joins these cylinders to a pump placed inside the scrotum (between the testicles). When the pump is engaged, pressure in the cylinders inflate the penis and makes it stiff. Inflatable implants make a normal looking erection and are natural feeling for your partner. Your surgeon may suggest a lubricant for your partner. With the implant, men can control firmness and, sometimes, the size of the erection. Implants allows a couple to be spontaneously intimate. There is generally no change to a man's feeling or orgasm.
Consequently, this negatively affects sexual function. Finally, if you frequently suffer from stress, then Vitamin B2 deficiency surely takes place. And the symptoms of this deficiency include peeling lips, cracked lips, stomatitis, tongue inflammation, skin lesions resembling eczema, conjunctivitis, photophobia, lacrimation, and decrement in visual acuity.
Much of the evidence shows high rates of vitamin D deficiency in patients with erectile dysfunction. In fact, one study of 3,400 participants found that men with vitamin D deficiency were 32% more likely to have trouble with erections when all other risk factors were controlled for. It’s a little on the nose that you need vitamin D for your “D,” but hey—science can be funny too.
