But in this case, zinc is much harder to absorb. This explains a decrease in testosterone levels in vegetarians. Slippery jack mushrooms, button mushrooms, beef liver, and fish are also rich in zinc. They are followed by breadstuffs, egg yolk, rabbit, chicken, beans, tea, and cocoa. In addition, zinc is found in onions, garlic, and rice. And a very small amount of zinc is available in fruits, vegetables, and milk.
Stress is another main cause of impotence in men. Psychological stress lowers libido in general and may suppress a man’s ability to become aroused, causing impotence. This is usually temporary and is easier to reverse than cases of physiological impotence. Nonetheless it is extremely important to manage stress levels when working to reverse impotence. Whether a man is experiencing impotence due to physiological reasons or psychological reasons, stress plays a key role. Any man that is experiencing erectile dysfunction will experience higher levels of stress because of the condition itself. Stress management skills need to be in place when working to reverse impotence.
Call this the Marvin Gaye of amino acids: L-arginine converts to nitric oxide (NO), a naturally occuring gas that causes blood vessels to relax and facilitate blood flow, helping you get and stay hard. You can find plenty of the nutrient in oysters, but in supplement form, the Mayo Clinic says that 400-6,000 milligrams is the maximum dose. And these are the best foods for arginine!
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.
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.
Pay attention to your vascular health. High blood pressure, high blood sugar, high cholesterol, and high triglycerides can all damage arteries in the heart (causing heart attack), in the brain (causing stroke), and leading to the penis (causing ED). An expanding waistline also contributes. Check with your doctor to find out whether your vascular system — and thus your heart, brain, and penis — is in good shape or needs a tune-up through lifestyle changes and, if necessary, medications.
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.
We have presented objective evidence that yohimbine has a positive effect in men with organic erectile dysfunction. This is contrary to the blanket statement of the American Urological Association in their clinical guidelines for erectile dysfunction, which states: ‘Based on the data to date, yohimbine does not appear to be effective for erectile dysfunction and, thus, it should not be recommended as treatment for the standard patient.’17 Our data strongly suggest that yohimbine treatment should be revisited. Our study was observational with dose-escalation just to see if there was any rationale to expect any effect in men with organic erectile dysfunction, especially in men who do not have the risk factor of tobacco abuse. The next step would be a double-blind, placebo-controlled study using yohimbine in smokers vs non-smokers to verify the current observation. We believe that our data justify such a trial. Yohimbine will never be a first-line drug for erectile dysfunction, but may be useful in subsets of men with mild disease or few risk factors. Yohimbine might also be useful in combination therapy with other treatment modalities such as sildenafil and intraurethral alprostadil, when they do not produce adequate effects alone, as has already been shown with naloxone39 or trazedone.40
Zinc is a trace metallic element that occurs naturally in the earth. Certain vegetables, meats, and seafood have more zinc content than others. This makes it fairly easy to obtain zinc through a varied diet. An extreme zinc deficiency is rare in the United States, as most people get some zinc through the foods that they eat. However, when levels of zinc fall below the recommended threshold, problems begin.
