Participants in this study gradually increased their daily intake of niacin from 250 mg to 3,000 mg over 36 weeks. Nine of the 23 people who were taking immediate-release niacin withdrew from the study early because of facial flushing, fatigue, or skin discoloration. Eighteen of the 23 who were taking 3,000 mg daily of sustained-release niacin dropped out due to upset stomachs, fatigue, or abnormal liver function tests. All of these side effects disappeared once the participants stopped taking the vitamin. Additional cause for concern comes from other reports suggesting that high doses of sustained-release niacin can cause jaundice and liver failure.
Having your current medication checked – if you are taking medication already, it could be that your erection problems are a side effect. Have a doctor check whether this is the cause of your problems and if it is, you might be able to switch medications and then find that your erectile dysfunction goes away completely – or at least improves. Medications that can cause erection problems include:
Ancient Incans consumed this energizing Peruvian plant before battle or a bout of sex, Chris Kilham, an ethnobotanist at the University of Massachusetts at Amherst, told Outside Online. Maca increases sexual appetite, stamina, endurance, and fertility. One 2008 study conducted at the Depression Clinical and Research Program at Massachusetts General Hospital in Boston found that maca helped people with antidepressant-induced sexual dysfunction to regain their libidos.

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.

When a man becomes sexually excited, muscles in their penis relax. This relaxation allows for increased blood flow through the penile arteries. This blood fills two chambers inside the penis called the corpora cavernosa. As the chambers fill with blood, the penis grows rigid. Erection ends when the muscles contract and the accumulated blood can flow out through the penile veins.
A cold slice of watermelon can do more than just satisfy thirst and hunger during the warm summer months; it can help with bedroom satisfaction. Citrulline, the amino acid found in high concentrations of watermelon, is found to improve blood flow to the penis. A 2011 study revealed men who suffered from mild to moderate ED and took L-citrulline supplementation showed an improvement with their erectile function and were very satisfied. Natural watermelon juice, or “nature’s Viagra,” can also be easier on the stomach, since taking pills like Viagra can cause nausea and diarrhea.
Penile erection is a hemodynamic process involving increased arterial inflow and restricted venous outflow, coordinated with corpus cavernosum and penile arterial smooth muscle relaxation. Any problem in this mechanism results in Erectile Dysfunction and its etiology is generally multifactorial. This study is aimed at determining the objective outcome of aerobic training in the management of Erectile Dysfunction of arterogenic origin using Meta analysis.
When given orally, yohimbine reaches peak levels in 10–15 min, and the half-life is 0.6 h. The efficacy of yohimbine in sexual function has been questioned, perhaps because of early questionable multidrug preparations.10,11 Yohimbine has been shown to have some effect on psychologic erectile dysfunction12,13 and in reversing fluoxetine-induced sexual dysfunction.14
Erectile dysfunction can occur as a side effect of medication taken for another health condition. Common culprits are high blood pressure meds, antidepressants, some diuretics, beta-blockers, heart medication, cholesterol meds, antipsychotic drugs, hormone drugs, corticosteroids, chemotherapy, and medication for male pattern baldness, among others.
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.   
If other options sound boring, maybe you should consider a fun, revved-up option like salsa dancing. You and your partner can lose yourself in the music, and it’s an intense exercise that engages the senses, combining cardio, balance, and coordination. Plus salsa dancing is great for keeping weight under control because it burns a lot of calories. Furthermore, it’s an activity that can build self-confidence, and if you’re single, the classes can be terrific for meeting new people. Regular exercise doesn’t have to be drudgery, and there are many types of dance classes that can seriously improve fitness and help you address erectile dysfunction.
On the other hand, high zinc levels have negative effects on sperm quality. Excessive zinc intake in mice have indicated a negative effect of increasing doses of zinc on sperm count and motility.[5] Although there have been studies focusing on various aspects of zinc related reproductive functions, studies on zinc related sexual behavioral aspects have received scant attention. In one study, intranasal irrigation with zinc sulphate has been reported to completely abolish the sexual behavior of male rats.[6]
Yohimbe has been found to increase circulation to the erectile tissues; aiding in the resolution of physiological and psychogenic (mental/emotional) impotence. Impotence, the inability to sustain erection, is the most common sexual disorder among men. Yohimbine is the active component found in yohimbe bark. Yohimbine has been shown to dilate the blood vessels and lower blood pressure, which enlarges the vessels in the sexual organs and increases reflex excitability in the lower spinal cord. In many cases, yohimbe has shown to make erections firmer. It is thought to help sustain an erection by causing compression and preventing blood to flow back out of the penis while sexually aroused.
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.
Where it comes from: Yohimbe is derived from the bark of a west African evergreen tree. Yohimbine is an active chemical (an alkaloid) found in said bark and is cultivated into supplement form. Yohimbine hydrochloride is a standardized form of yohimbine that is available as a prescription drug in the United States. These terms are all related but are interchangeable.
The Florida Sexual History Questionnaire, a 20-item questionnaire that assesses interest and desire for sexual activity, sexual development, current sexual behaviors, and satisfaction with current sexual activity, was used to assess male sexual dysfunction. Individuals responded to each question by choosing one of six ordinally scaled response categories, with higher scores representing better functioning. Scores on the Florida Sexual History Questionnaire have been shown to significantly discriminate between men with and without impotence25 and between men with primary organic and primary psychogenic erectile dysfunction.26 According to Geisser et al,25 the Florida Sexual History Questionnaire has high internal consistency as well as split-half reliability. Chronbach's alpha has been reported to be as high as 0.90, and Spearman Brown's coefficient is reported to be 0.86.
The number of animals ejaculating within 15 minutes was significantly reduced in 5 mg zinc treated group (one out of eight). However, all intromitted rats ejaculated between 20-30 minutes when observation was continued. Ejaculatory latency was significantly high in this group compared to controls; 711.60 Sec (SEM 85.47) vs. 489.50 Sec (SEM 67.66), P < 0.05. Similarly, they showed a significantly higher frequency of penile thrusting compared to controls; 26.50 (SEM 6.17) vs. 52.80 (SEM 11.28), P < 0.05 [Table 1].
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.
E.D. may just be that early warning sign. Erections depend on blood flow, and blood flow depends on nice, wide-open arteries. Atherosclerosis doesn’t just affect the arteries around your heart; if you have plaque build-up, you are likely to have it all around the arterial system — and the penile artery is one of the smallest arteries you have (no matter what you claim about your size). So if you have atherosclerosis, then the plaque there will be one of the first places where you would notice a decline in blood flow.

Magnesium helps regulate levels of calcium, zinc, and other vitamins and minerals. It also helps the body produce energy and contributes to proper organ function. Most people don’t develop a genuine magnesium deficiency, even if they don’t get enough of the mineral in their diets, according to the University of Maryland Medical Center. A true magnesium deficiency, however, may increase the risk of erectile dysfunction.


Zinc is vital for the organism and it’s even more important for men because it inhibit the transformation of testosterone into dihydrotestosterone, it has an important role in the prostate health. The urologist recommended my dad to take a supplement that has zinc and after a good research I found him a supplement on amazon named alpharise, it has zinc, vitamin B9, pumpkin seeds (also a good source of zinc). There has been a huge difference between the after and before alpharise in my dad’s health (prostate)
Science is always on the search for the magic bullet for our sexual health problems – that female Viagra. Most women, however, experience poor sexual desire alongside other issues like PMS and fatigue. The solution requires a holistic approach. I want women to start by feeling good every day, in everything they do, as it’s then that you will find you have the ability to feel great about sex.
Controlling stress, having a healthy diet, and getting enough sleep to create a good foundation for sexual satisfaction. But sometimes the basics aren’t quite enough. Millions of men experience erectile dysfunction (ED), but ED can usually be successfully treated with prescription medications like Viagra, Levitra, Staxyn, and Cialis. These drugs have helped men understand that ED isn’t all in their mind, have opened up the topic to a more honest discussion, and have transformed many men’s sex lives.
The Medline (Pubmed) electronic database was searched (from June 1972 to November 2010) for systematic reviews that evaluated the effects of therapeutic exercise on ED. The key words and search terms used to develop the search strategy for each of these databases included: exercise therapy, aerobic exercise, therapeutic exercise, rehabilitation exercise, impotence and erectile dysfunction. In addition, the electronic searches were supplemented by checking the reference lists of any relevant identified articles.
That’s no joke. Like every part of the body, the male repro system needs the right nutrients for optimal health, from function to fertility. Studies have isolated several nutrients that are particularly beneficial. You can get them through these best foods for your penis, or these best proteins for your penis, but we’ve broken them down here by nutrient in case you want to ensure you’re getting enough. (And if you do decide to go the supplement route, as always, talk to your doctor and never exceed recommended dosages.)
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. 
An Italian study in 1994 on 63 patients with psychogenic impotence showed that yohimbine, the active ingredient in the inner bark of the Yohimbe tree, improves libido and sexual stimulation. Half of the patients were given 15mg orally of yohimbine and the antidepressant trazodone 50mg orally per day, the other half a placebo, over an 8-week period. Of the half that received the yohimbine, 71 percent had an increase in sexual desire, erectile function, and ejaculation, as compared with only 22 percent in the placebo group. Patients receiving the placebo then were given the yohimbine tablets over a new 8-week course and of that group, 74 percent showed improvement. After a 3- and 6-month follow-up, positive results were maintained in 58 percent of the patients. To me this is very notable, as the antidepressant trazodone is known to cause sexual dysfunction as a side effect.

The group treated with the lower concentration of zinc (1 mg/day) did not show an alteration in any of the observed parameters. However, supplementation with a dose of 5 mg/day per rat caused substantial prolonged ejaculatory latency and increased in number of penile thrusting. The other parameters studied remained unchanged indicating uninterrupted libido, sex vigor and performance. Majority of male rats (75 %) showed the prominent actions of sexual behaviour (mount, intromission and penile thrusting) and did not ejaculate within the 15-minute observation period.
Wistar rats (From Medical Research Institute, Colombo) were obtained and kept in a well ventilated animal house under natural dark light cycle (temperature 28-30°C, humidity; 50-55%). Animals were housed in groups (four per group) until they reached sexual maturity (150-200 g). They were provided with pelleted food and water. Male rats were permitted access to receptive females on three separate occasions and then screened for sexual proficiency. Male rats who displayed consistently vigorous sexual activity were selected for the study.

This mineral is needed for a healthy sex life and a deficiency is linked to low testosterone levels which contributes to weaker erections. Zinc supplements can significantly improve matters in the bedroom. Food items loaded with Zinc can include oysters, shellfish, nuts and seeds. Erectile dysfunction and loss of interest in sex life can be caused by many physical and psychological reasons. Keep yourself healthy by consuming these vitamins and a healthy diet that is high in fibre and nutrients. Try to ignore OTC medicines like I-Arginine and other pills, and start including these fresh vegetables, apples, oats and whole grains in your daily life. 
So what causes erectile dysfunction?  Sometimes it is a circulation problem.  Sometimes it is a low testosterone issue.  Sometimes it is not.  Testosterone (T) supplementation can help ED and low libido in cases of low T and even if there is a normal T level at baseline, ED can be helped.  In cases where thyroid under or overactivity is causing T levels to be less than optimal.  Aging is also a problem as T levels drop after mid 20’s and as adipose tissue increases and aromatase enzyme conversion of T to Estrogen correspondingly increases.  This causes an unfavorable E:T ratio which equates to low T.
The paired t-test was used to assess differences in responses using various doses of yohimbine in responders and nonresponders. Responder and nonresponder changes in tumescence, rigidity, and other physiologic responses over the entire study period were compared using independent t-tests (assuming equal variances). Independent t-tests were repeated to determine whether significant differences existed in the mean numbers of risk factors, age, or side effects among groups. Matched pairs t-tests were used to compare Florida Sexual History Questionnaire responses at each dose. Finally, χ2 analysis (or Fisher's exact test when appropriate) was used to compare the two groups on dichotomous sexual satisfaction ratings at the end of the trial; 95% confidence intervals were consistently examined to determine the magnitudes of differences detected. Two-tailed P-levels were used in reporting all results. SPSS 9.0 statistical software (SPSS Inc, Chicago, IL, USA) was used for analysis.
Ashwagandha, an Ayurvedic herbal remedy reputed to act as a mild aphrodisiac, or Asian ginseng (Panax ginseng), a good stimulant and sexual energizer. For either, follow the dosage on the package, and give it six or eight weeks to have an effect. Both ashwagandha and Asian ginseng are generally safe (but Asian ginseng can raise blood pressure and cause irritability and insomnia in some people).
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).

Yohimbe supplements often list yohimbe bark extract or yohimbine as the active ingredient. However, some of these products might not provide accurate information about the amount of yohimbine in the supplement. Also, some yohimbe supplements list yohimbine hydrochloride as an active ingredient. Yohimbe products containing man-made yohimbine hydrochloride as an ingredient are not legal to sell as a dietary supplement in the US.
A vacuum erection device is a plastic tube that slips over the penis, making a seal with the skin of the body. A pump at the other end of the tube makes a low-pressure vacuum around the erectile tissue, which results in an erection. An elastic ring is then slipped onto the base of the penis. This holds the blood in the penis (and keeps it hard) for up to 30 minutes. With proper training, 75 out of 100 men can get a working erection using a vacuum erection device.
Research has shown that the same eating patterns that can cause heart attacks due to restricted blood flow in the coronary arteries can also impede blood flow to and within the penis. The blood flow is needed for the penis to become erect. Diets that include very few fruits and vegetables along with lots of fatty, fried, and processed foods can contribute to decreased blood circulation throughout the body.
As an alpha-2 antagonist, yohimbine promotes sympathetic activity. According to a number of studies, yohimbe can increase blood pressure. This is why it’s useful for things like erectile dysfunction or diabetic nerve problems. Yohimbine is sometimes used to treat low blood pressure and symptoms like dizziness when standing up. It works by dilating blood vessels and acting on the sympathetic nervous system. However, it’s important to point out that increased blood pressure can also be a problem for some people, especially those with existing cardiovascular problems, people taking blood pressure medications, or those who already have high blood pressure.
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.
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.   
In the statistical analysis, the difference between the pre-test and post-test values (changed score) for IIEF score was computed. Student t-test was used to compare the mean changed score values of IIEF. All statistical analysis was performed on an IBM compatible micro computer using SPSS for window version 15.0, (Chicago IL, USA). The probability level for all the above tests was set at 0.05 to indicate significance.
For many men, stopping smoking is an erectile dysfunction remedy, particularly when ED is the result of vascular disease, which occurs when blood supply to the penis becomes restricted because of blockage or narrowing of the arteries. Smoking and even smokeless tobacco can also cause the narrowing of important blood vessels and have the same negative impact. 
As mentioned above, the extract of yohimbe bark has been used as an aphrodisiac for centuries. Recently, yohimbe supplement also became popular for its bodybuilding and fat-burning properties, despite the lack of data to support it as a dieting agent. In addition, supplement manufacturers claim that yohimbe can be used for the following applications:6,7

ED can also occur among younger men. A 2013 study found that one in four men seeking their first treatment for ED were under the age of 40. The researchers found a stronger correlation between smoking and illicit drug use and ED in men under 40 than among older men. That suggests that lifestyle choices may be a main contributing factor for ED in younger men.
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.”
