Many people experience occasional erectile dysfunction when they're stressed or preoccupied. This is because stress increases levels of the hormone adrenaline, which actually causes blood vessels to contract. As having a firm erection depends upon a strong supply of blood to and within the penis, feeling chronically stressed can lead to repeated bouts of ED.
Although not direct proof of cause and effect, the positive results that we report in half of the men in the current study may reinforce our clinical observation with objective RigiScan™ data that use of yohimbine might be associated with better effects in nonsmokers. We30 reported that cessation of smoking may rapidly improve nocturnal erectile activity and found that nicotine was not the noxious agent in our study. We postulated that carbon monoxide might create a hypoxic environment in the penis. This effect probably was mediated through restoration of nitric oxide activity.31
In addition to getting helpful nutrients from your diet, you can also consider supplementing. Many of these are also on my list of top five supplements to increase sex drive, so they’re helpful for overall sexual health. It’s a good idea to check in with a practitioner, particularly one with knowledge of your individual health issues and medications, before taking anything. Here are some I recommend:

Talk with your doctor about going to a counselor if psychological or emotional issues are affecting your ED. A counselor can teach you how to lower your anxiety or stress related to sex. Your counselor may suggest that you bring your partner to counseling sessions to learn how to support you. As you work on relieving your anxiety or stress, a doctor can focus on treating the physical causes of ED.
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.
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.
Partner preference index in both 5 mg zinc treated group and controls was positive. In the control group, time spent by males, with estrous and diestrous females, was 21.75 sec. (SEM 2.26) and 13.62 sec. (SEM 1.05) respectively. In the zinc treated group they spent 20.87 sec. (2.09 SEM) with estrous and 14.37 sec. (SEM 0.70) with diestrous females. The PPI of controls and zinc treated group was 8.12 Sec. (SEM 2.32) and 6.50 Sec. (SEM 1.76) respectively. There was no significant difference between the two groups, P > 0.05.

Female rats were injected subcutaneously estradiol benzoate 12 μg in olive oil and 0.5 mg progesterone (Sigma chemicals, USA) in olive oil, 48 hrs and six hours prior to introduction to the males.[11] A cervical smear was observed under a light microscope and females in their estrous cycle were included in the study. Observations were performed during the dark phase of the day cycle (19.00 hours) under dim red light. After two hours of the last dose, rats were placed individually in transparent observation cages for 15 minutes adaptation period. A stimulus-receptive female was introduced to each male by gently dropping them in to the observation cage.

Using the protocol of a clinical randomized placebo-controlled parallel-group trial, the study also took place at the University of Hong Kong. One hundred sixty male patients with ED and dyslipidemia were randomized into two groups receiving either up to 1,500 mg of oral niacin daily or placebo for 12 weeks. Using questions from the International Index of Erectile Function (IIEF, particularly questions Q3 and Q4), the primary outcome was improvement in erectile function. Q3 ranked “frequency of penetration,” while Q4 ranked “frequency of maintained erections after penetration.” Other outcome measurements included the total IIEF score, IIEF-erectile function domain, and Sexual Health Inventory for Men (SHIM) score.

They found that men who exercised the most were also the most likely to have higher scores in sexual function. Specifically, those who expended 18 METS, or metabolic equivalents, per week were most likely to enjoy sex. METS is a physiological measurement that denotes the amount of energy a person spends on a specific activity, as well as the intensity of it. According to the researchers, 18 METS was equal to about two hours of strenuous exercise like running or swimming, 3.5 hours of moderate-intensity exercise, or six hours of light exercise.   
"Erectile dysfunction can be a very serious issue because it's a marker of underlying cardiovascular disease, and it often occurs before heart conditions become apparent. Therefore, men should consider improving their weight and overall nutrition, exercise more, drink less alcohol and have a better night's sleep, as well as address risk factors such as diabetes, high blood pressure and cholesterol.

Nitric oxide is made internally from L-arginine, which is an amino acid found in red meat, poultry, fish, and dairy products. In other words, L-arginine is the building block for nitric oxide, which is essential for erections. A lack of one can lead to a lack of the other. However, there’s a problem when it comes to treating L-arginine deficiency with supplements.


Green vegetables, legumes, seeds, nuts and brown rice are among the best sources of dietary magnesium. Most other foods don’t contain enough of the mineral to contribute to daily recommended levels, which is why many people choose to take a magnesium supplement or a daily multivitamin that contains magnesium. If you’re concerned about your overall magnesium level, particularly as it relates to erectile function, discuss supplement options and dietary changes with your doctor.
The number of intromissions in the 5 mg/day group was comparable with controls. On the other hand number of penile thrusting was significantly increased with the same dose. These are indications of unimpaired erectile function due to supplemented zinc. Our observations also confirmed the lack of aberrant sexual behavior which is indicative of uninhibited penile tactile sensations.[15] Sexual behavior may also be changed with motor weaknesses and incoordination.[12] Supplementation with zinc did not impair muscle strength or coordination when tested with bar and bridge tests, indicating that prolongation of ejaculation was not mediated through these mechanisms.
Vitamin B6 deficiency leads to irritability, numbness in the extremities, muscle weakness, fatigue, drowsiness, impaired mental activity, peripheral neuritis, seborrheic dermatitis, stomatitis, conjunctivitis, and, of course, impairment of sexual potency. Lack of this vitamin can be a result of long-term use of anti-tuberculosis drugs and chronic diseases of the gastrointestinal tract.
Although not every study has shown that yohimbe can have slimming effects, certain other studies have found positive results. One study found that yohimbine significantly increased mean weight loss in overweight female patients following a low-energy diet. (12) Possible mechanisms of action include: boosting lipolysis (the breakdown of fats and other lipids by releasing fatty acids into the blood) both during and following exercise, regulating insulin secretion, and reducing appetite. (13)
The truth is medication or psychosexual counselling are the first treatments a doctor will suggest because they’ve been proven to work. If a doctor has approved a medication for you then it’s safe. If you would still like to see if herbal supplements work for you, then there is a list below of supplements thought to work for erectile dysfunction. Just before you invest your money in them, remember they aren’t proven to work:

Stimulant drugs speed up the nervous system. By speeding up the nervous system, stimulant medications can make you feel jittery and speed up your heartbeat. Yohimbe might also speed up the nervous system. Taking yohimbe along with stimulant drugs might cause serious problems including increased heart rate and high blood pressure. Avoid taking stimulant drugs along with yohimbe.

Selenium, found in Brazil nuts, liver and oysters, is a trace mineral that plays an important role in hormone health. You only need a tiny bit for healthy sperm, but a tiny deficiency can be catastrophic for reproductive health. In one study, men who had lower testosterone and were infertile also had significantly lower selenium levels than the fertile group. Supplementing with the mineral improved chances of successful conception by 56 percent. And a second British Journal of Urology study that included 69 infertile men with low levels of the mineral, found selenium supplementation could significantly improve sub-par sperm motility associated with testosterone deficiency.

Male erectile dysfunction (ED) has been defined as the persistent inability to attain and/or maintain an erection sufficient for sexual performance (1). ED is very common, and its prevalence as well as severity increases with age (2). It has been recognized that the major cause of ED is atherosclerosis affecting the pelvic vasculature (3). The presence of ED has been known to predict future cardiovascular disease, and early detection may allow timely modification of remediable risk factors, or lead to the diagnosis of occult cardiovascular disease (4, 5).

In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction. 
The herb is particularly effective for those whose willy woes are based on other medications: An older study from the University of California found ginkgo biloba is 76% effective in treating sexual dysfunction caused by antidepressants. “Gingko helps counteract sexual dysfunction caused by certain antidepressants called SSRIs by blocking serotonin activity in the erectile centers of the brain, ultimately leading to better synthesis and bioavailability of nitric oxide,” Walker explains.
Taking high doses can also cause other severe problems, including difficulty breathing, paralysis, very low blood pressure, heart problems, and death. After taking a one-day dose of yohimbine, one person reported an allergic reaction involving fever; chills; listlessness; itchy, scaly skin; progressive kidney failure; and symptoms that looked like the auto-immune disease called lupus.
Our bodies are designed to be active and in motion. By keeping active and engaging in regular aerobic exercise, you increase the blood flow to your muscles, and your penis along the way. One of the most interesting things about increasing your blood flow is that it becomes a signal to your blood vessels to grow and get wider. It benefits your brain, your heart, and your erection. The principle of "use it or lose it" is the best advise one can follow. In fact, if you don't engage in sexual activity at least once or twice a week, it would be beneficial to masturbate. This not only helps with prostate health, but encourages the blood vessels that contribute to your erection to maintain their patency and flow. 

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.
Most studies related to male infertility show a clear concise relationship between zinc and ed. During a study some young men were given a diet which included very little amounts of zinc and thus they developed a zinc deficiency. When testosterone levels were measured after 20 weeks of low-zinc diet it was found that the level of the hormone had drastically reduced. The study also found that in elderly men, with an increase in the uptake of zinc, testosterone levels nearly doubled.
To evaluate the patients' response clinically in the office, a simple grading system was used.27 The patients were asked about the quality of their erections, which were graded as follows: grade 1, tumescence but no rigidity; grade 2, tumescence with minimal rigidity; grade 3, rigidity sufficient for sexual intercourse; and grade 4, fully rigid erection. At the end of the study, patients were graded as to whether they thought they had improved enough to have satisfactory regular intercourse, which is defined as success in 75% of attempts. The degree of subjective improvement in intercourse was used to classify patients as ‘responders’ vs ‘nonresponders’ in subsequent analyses. A log was kept by the couple of their sexual activity, and it was taken to the clinic for review by the clinical investigator.
People who do not have any contra-indications (see below) generally tolerate it well. However, taking yohimbe can sometimes cause side effects including: high blood pressure, headaches, anxiety, restlessness/nervousness, dizziness or shakiness. These side effects seem to affect people with a history of mental illness or mood-related problems most often. But it’s possible for them to develop in anybody.
There have been some studies to suggest that a placebo effect that improves ED may work for some men. One study found that men taking an oral placebo pill showed as much improvement in ED symptoms as men who took actual medication to improve ED. Conversely, men who were given therapeutic suggestions to improve ED did not see signs of symptom improvement.

b) Men With Digestive Disorders.  There are many, many GI disorders that plague modern, urban dwellers:  atrophic gastritis, Crohn's, diverticulitis, enzyme deficiencies, IBS, ulcerative colities and on and on.  All of these can lower vitamin and mineral absoprtion.  Men struggling with these issues may very well benefit from increased amounts of niacin in the diet or possibly with supplementation.

[notice color=’#ebebeb’]Vitamin B2 (riboflavin) takes an active part in the production of certain hormones and erythrocytes and in the synthesis of ATP, a so-called life fuel. In addition, it protects the human retina from excessive exposure to UV radiation, ensures the dark adaptation of the human eye, increases visual acuity and perception of colour and light. Riboflavin is needed for tissue growth and tissue regeneration.[/notice]
Erectile dysfunction (ED) is commonly called impotence. It’s a condition in which a man can’t achieve or maintain an erection during sexual performance. Symptoms may also include reduced sexual desire or libido. Your doctor is likely to diagnose you with ED if the condition lasts for more than a few weeks or months. ED affects as many as 30 million men in the United States.
For best results, men with ED take these pills about an hour or two before having sex. The drugs require normal nerve function to the penis. PDE5 inhibitors improve on normal erectile responses helping blood flow into the penis. Use these drugs as directed. About 7 out of 10 men do well and have better erections. Response rates are lower for Diabetics and cancer patients.
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.
Clinical trials were included if they met all of the following inclusion criteria: study population defined; Men with arteriogenic ED were considered; the present review was concerned with studies that used aerobic exercise on ED; only randomized controlled trials on this topic were selected for review; The main outcome measure was satisfactory intercourse without additional therapy using the International Index of Erectile Dysfunction (IIED) scores. The present review utilized studies that had successfully undergone rigorous peer review (i.e., published peerreviewed journals), were included.

Evidence from 5 randomized studies published in the years between 2004 and 2010, has demonstrated strong evidence that aerobic exercise can benefit people with arterogenic ED. These review results of this study build on and update the evidence from studies that concluded that concluded that exercise was beneficial for people with ED and cardiovascular disorders (25–27); on ED and obesity (18) and on normal subjects with ED (24). However, studies have shown common pathway for ED, cardiovascular (28 –30) and metabolic disorders (19, 31).
Overall, studies have been inconclusive about the aphrodisiac benefits of taking yohimbine supplements. However, most have found it works better than placebos. (7) According to a report published in the Iranian Journal of Psychiatry, a recent analysis of seven trials concluded that between 34–75 percent of men involved in studies experienced favorable results when taking between 5–10 milligrams.
