Test was terminated after 15 minutes of observation or after ejaculation (whichever occurred first). Ejaculatory latencies were taken as 15 minutes when animals showed intromissions but failed to ejaculate during the test period. After analyzing the results, the following tests were performed with the group that indicated significantly positive effects compared to the controls:
From the overall analysis, the niacin group showed a significant increase in both IIEF-Q3 scores (0.53 ± 1.18, P < 0.001) and IIEF-Q4 scores (0.35 ± 1.17, P = 0.013) compared with baseline values. The placebo group also showed a significant increase in IIEF-Q3 scores (0.30 ± 1.16, P = 0.040) but not IIEF-Q4 scores (0.24 ± 1.13, P = 0.084). However, when patients were stratified according to the baseline severity of ED, the patients with moderate and severe ED who received niacin showed a significant improvement in IIEF-Q3 scores (0.56 ± 0.96 [P = 0.037] and 1.03 ± 1.20 [P < 0.001], respectively) and IIEF-Q4 scores (0.56 ± 1.03 [P = 0.048] and 0.84 ± 1.05 [P < 0.001], respectively] compared with baseline values, but not for the placebo group. The improvement in IIEF-EF domain score for severe and moderate ED patients in the niacin group were 5.28 ± 5.94 (P < 0.001) and 3.31 ± 4.54 (P = 0.014) and in the placebo group were 2.65 ± 5.63 (P < 0.041) and 2.74 ± 5.59 (P = 0.027), respectively. There was no significant improvement in erectile function for patients with mild and mild-to-moderate ED for both groups. For patients not receiving statins treatment, there was a significant improvement in IIEF-Q3 scores (0.47 ± 1.16 [P = 0.004]) for the niacin group, but not for the placebo group.
Exercise helps to maintain blood circulation to this region and strengthens your heart so it can pump blood more effectively when at rest. As you exercise, your blood vessels dilate and more capillaries open so that blood can effectively be moved to where it is needed. Much of this blood is routed via the genital region, opening the network of vessels which feed the penis. The region will receive an improved circulation as a result even when your body is at rest, and increased blood flow to the skin itself brings the added benefit of greater sensitivity.
Several studies have shown that erectile dysfunction is somehow linked to problems with cardiovascular health — which one comes first has been the question. It makes sense; the penis becomes erect through a complex system of blood vessels and spongy tissue called the corpora cavernosa — this is where the blood gets trapped, causing the erection. When problems arise through this system, whether they’re caused in the brain or through problems with the blood vessels, the penis can’t get erect.
There was a higher incidence of adverse events in those taking niacin. However, most patients could tolerate it at the maximum dosage (1,500 mg/day). With this in mind, niacin could be an alternative choice of treatment for patients with ED. Despite the success of phosphodiesterase type 5 inhibitors (PDE5 inhibitors), such as sildenafil, only around 60–70% of patients have a satisfactory response to this class of drugs. And there are adverse effects such as headache, flushing, dyspepsia, nasal congestion, and impaired vision, including photophobia and blurred vision. Hence, there is a need to develop other therapeutic agents for those patients who do not respond satisfactorily to PDE5 inhibitors or are contraindicated for those such as sildenafil.
Yohimbe is usually taken orally, but it may also be administered intravenously for certain cases. Weight is also sometimes used as a guide to determine the dosage of this supplement. A 150-pound (lb.) person should take roughly 14 mg of yohimbe per day, while those who weigh 200 lbs. and 250 lbs. should take around 18 mg and 22 mg yohimbe, respectively.
Erectile dysfunction supplements and other natural remedies have long been used in Chinese, African and other cultures. But unlike prescription medications for erectile dysfunction, such as sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis, Adcirca) and avanafil (Stendra), erectile dysfunction herbs and supplements haven't been well-studied or tested. Some can cause side effects or interact with other medications. And the amount of the active ingredient can vary greatly from product to product.
There are risks to prosthetic surgery and patients are counselled before the procedure. If there is a post-operative infection, the implant will likely be removed. The devices are reliable, but in the case of mechanical malfunction, the device or a part of the device will need to be replaced surgically. If a penile prosthesis is removed, other non-surgical treatments may no longer work.

You may also perform these exercises anywhere and anytime. Just take note in your calendar if you sometimes have problems remembering. On the other hand, aerobic exercises may also improve your cardiovascular health, aside from just your male sexual health. By doing so, you can also experience an improved capability of achieving and maintaining erection.
Research in the medical journal Experimental and Therapeutic Medicine found that supplementing with the mineral zinc, along with the vitamins folic acid and biotin, as well as the herb Rhodiola rosea improved ejaculatory control in males suffering from premature ejaculation. Premature ejaculation is a common type of sexual dysfunction that affects 20 to 30 percent of men between the ages of 18 and 55. The low incidence of any side-effects of these natural treatments may also make it preferable to drug treatments by many men.
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.
Because cholesterol is a building block for testosterone, drugs that interfere with cholesterol production can lower levels of this hormone (Journal of Sexual Medicine, April, 2010). French and Dutch researchers have reported that decreased libido and erectile dysfunction may be associated with statin-type drugs (British Journal of Clinical Pharmacology, Sept. 2004; Drug Safety, July, 2009).

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.
Motivated by philosophers that included John Locke (the most influential of Enlightenment thinkers), Voltaire, Newton, and Leibniz, ruling princes throughout Europe endorsed and fostered the intelligentsia of the Enlightenment. Some of these rulers even attempted to apply the ideas of the enlightenment to government. When grasped by “natural aristocrats,” the Enlightenment was particularly successful in America where it influenced Benjamin Franklin and Thomas Jefferson, among many others, and fueled the fires that led to the American Revolution, the Declaration of Independence, and the creation of the United States.
Saw palmetto. Saw palmetto comes from the fruit of a small palm tree. It has been used to treat symptoms in men with an enlarged prostate gland, such as difficulty urinating, and it has been recommended to treat ED caused by an enlarged prostate. However, several recent clinical trials did not show that saw palmetto works any better on an enlarged prostate than a placebo does. "There is no evidence that saw palmetto should be used to treat erectile dysfunction," says Dr. Gilbert. Like ginkgo biloba, saw palmetto can interact with some prescription medications.
Due to its ability to inhibit actions of the sympathetic nervous system, yohimbe can help to bring blood pressure levels back to balance. This is is why it’s used to sometimes increase blood flow, such as to tissues of the reproductive organs.  Or, also why it’s used to treat hypotension (abnormally low blood pressure). It may also be helpful for stimulating nerves and treating fatigue or symptoms of depression.
Allow me to explain. We know that cardiovascular disease is the number-one killer of men in the United States. Well, the “vascular” part of cardiovascular disease means that the cause is really blockage of the arteries around the heart, a process called atherosclerosis. It’s proven that over half of heart attacks occur in men with normal cholesterol. And many times, heart disease develops without warnings, causing sudden cardiac arrest.  So any early warning sign can be a life saver — and might compel you to get checked out before the big one hits.
Esposito et al (18), in their randomized study investigated the effect of physical activities on 110 obese subjects. They reported significant effect of physical activities on both body mass index and EF. The physiological rationales underlying this hypothesis are that healthy lifestyle factors are associated with maintenance of good erectile function in men (19); obesity has been positively associated with endothelial dysfunction and increased serum concentrations of vascular inflammatory markers (34, 35); and both endothelial and erectile dysfunction may share some common metabolic and vascular pathways that may be influenced by behavioral-related pathways (19, 36). Obese men with erectile dysfunction had evidence of abnormal endothelial function, which was indicated by reduced blood pressure and platelet aggregation responses to L-arginine and elevated serum concentrations of markers of low-grade inflammation, such as IL-6, IL-8, and CRP. It has been shown that there are significant associations between IEEF score and proxy indicators of elevated body fat, the vascular response to L-arginine, and circulating IL-8 and CRP levels. The association we found between IEEF score and indices of endothelial dysfunction supports the presence of common vascular pathways underlying both conditions in obese men. A disturbance in nitric oxide activity linked to reduced nitric oxide availability could provide a unifying explanation for this association. In particular, in isolated corpus cavernosum strips from patients with erectile dysfunction both neurogenic and endothelium-dependent relaxation is impaired (37).

Yohimbe bark (pronounced yoh-heem-buh) is an herbal supplement associated with anti-aging effects. It is used to naturally treat erectile dysfunction, low libido, hormonal imbalances and symptoms like low energy. Yohimbe has a long history of use in Western Africa, where the plant originates. It’s still grown there today, especially for its apparent aphrodisiac abilities.
Some medications that are changed by the liver include amitriptyline (Elavil), clozapine (Clozaril), codeine, desipramine (Norpramin), dextromethorphan, donepezil (Aricept), fentanyl (Duragesic), flecainide (Tambocor), fluoxetine (Prozac), meperidine (Demerol), methadone (Dolophine), metoprolol (Lopressor, Toprol XL), olanzapine (Zyprexa), ondansetron (Zofran), tramadol (Ultram), trazodone (Desyrel), and others.
One study found that sticking to a Mediterranean diet rich in virgin olive oil, vegetables, fruits, whole grains, nuts, and fish was associated with a lower risk of ED development and improvement in people who already suffered from ED. There is also some evidence that vegetarian and vegan diets may lower the risk of some types of heart disease, which in turn decreases the likelihood of developing ED.
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.
Regular cardiovascular exercise can not only improve erectile function, it can boost energy levels, lower blood pressure, and improve muscle tone. Furthermore, by reducing body fat and stress, regular cardio can improve a person’s self-image, improve sleep, and result in a more rested overall feeling. For maximum benefit, 20 to 30 minutes of cardiovascular exercise four or five times a week is ideal, and it may take time to work up to this. It’s smart to discuss this with your doctor if you have been living a sedentary lifestyle or haven’t had a physical in a while. The key to sticking with cardio is choosing an activity you enjoy so it won’t feel like a chore. Great choices in the cardiovascular exercise include:

Weak erection is one of the most embarrassing problems in this world because i was always shy to meet new partners due to the fact that i already know that i cannot perform at all and even when i did i was so weak. I could only last 45 seconds and this this made me to ask myself many a times if i am a man, four of my girlfriends left me due to this problem. In my search for a cure and a solution i told an old friend all i have been facing and he told me about Dr. MACK how he helped him save his marriage using his very effective ED medicine which restored back his erection. I contacted him and he sent me the medicine and that is one of the best decision i have ever made in my entire life. I think this will help someone out there if you have any ED related problem do not hesitate to contact [email protected] com i know he can help you.

Clinically I have seen these results in doses of just 20 mg twice daily.   It is important to note that prolonged zinc supplementation can lead to lowered copper levels so it is not advisable to continue this therapy unless it is in a cyclical nature.  For those on long term zinc there are combination products with Zinc and Copper.   In cases where some prescriptions that lower zinc are given, like acid lowering meds, thiazide diuretics and ACE inhibitors, or in renal dialysis patients, this chronic monitoring of zinc may lead to longer term supplementation.
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.

Yohimbine significantly increased subjective measurements of sexual desire, sexual satisfaction, frequency of sexual contacts, and erection quality during sexual intercourse. Each subject also underwent a sleep study and researchers found that yohimbine also objectively increased the rigidity of erections while sleeping. [12] Yohimbine appears to alleviate both physical and psychological symptoms associated with ED.


The lack of strong scientific proof that vitamin supplementation can improve erectile function doesn’t stop companies from selling vitamins, herbal supplements, and other products with the promise that they will do the job. ED is often treatable with prescription medications or medical procedures, so be careful not to get taken by a manufacturer’s empty promises.
The Enlightenment proved itself to be an intellectual movement in 18th Century Europe that mobilized the power of reason to advance knowledge and reform society. It promoted intellectual transaction and opposed intolerance and abuses by both Church and State. This constituted a challenge to and disparagement of the heavy-handedness of the State. Thus, society was lifted and enlightened.
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.
However, the case is entirely different for Niacin, as it is not only relatively more convenient, but also it allows men to enjoy sex any time when they want even when they take Niacin for only one time in a day for erectile dysfunction. Niacin formulates in the form of various slow-release pills designed primarily to seep in a slow way within the human bloodstream during the course of one day.

In fact, dyslipidemia is commonly found in ED patients, and studies show that statins can help to improve the response of PDE5 inhibitors in those suffering from ED precisely because they improve atherosclerosis. Consequently, statins can be used as a treatment in patients with an unsatisfactory response to PDE5 inhibitors, yet there are problems with statins too, among them raised liver enzymes and muscle problems, some of which can be quite serious and even deadly (rhabdomylosis).

In the New World, maize was traditionally treated with lime, an alkali now shown to make niacin nutritionally available and thereby reducing the chance of developing pellagra.1 However, when in the 18th century corn cultivation was adopted worldwide, treatment with lime was not accepted because the benefit was not understood. Thus in the New World, often heavily dependent on corn, cultivators rarely suffered from pellagra, which became common only when corn became a staple that was eaten without the traditional treatment. Of interest, if maize is not so processed, it is a poor source of tryptophan as well as niacin.
The improvements in IIEF-erectile function domain (IIEF-EF) score for moderate and severe ED patients in the niacin group were 3.31 and 5.28 and in the placebo group were 2.74 and 2.65, respectively. In the lower range of mild and mild-to-moderate ED, there was no significant improvement in erectile function. Of the 160 patients in the study, 32 were using statins; 18 in the niacin group and 14 in the placebo group. For patients not receiving statin treatment, there was a significant improvement in IIEF-Q3 scores (0.47) for the niacin group, but not for the placebo group. To summarize, niacin alone can improve the erectile function in patients suffering from moderate to severe ED and dyslipidemia.

These are not currently approved by the FDA for ED management, but they may be offered through research studies (clinical trials). Patients who are interested should discuss the risks and benefits (informed consent) of each, as well as costs before starting any clinical trials. Most therapies not approved by the FDA are not covered by government or private insurance benefits.
