Zinc affects different aspects of mammalian reproduction. Testicular disruption, impaired spermatogenesis and subsequent poor semen parameters are found in males with zinc deficiency. Testicular concentration of zinc was lower in male sheep fed with zinc deficient diets. The same animals showed smaller seminiferous tubules and less lumen development than the controls.[1] Similarly variable degrees of maturation arrest in different stages of spermatogenesis with reduced diameter of seminiferous tubules were noted when rats were fed with zinc deficient diets.[2] Zinc deficiency causes a reduction in the structural parameters of seminiferous tubules influences serum levels of testosterone (T) and prolactin (PRL) in rats.[3,4]
April 10, 2000 (Mill Valley, Calif.) -- In his early 40s, Ron Hanson was too young to be having trouble getting and sustaining erections. But like many men, he was too embarrassed at first to talk about the problem. Hanson (not his real name) waited seven years to see a urologist. By the time he spoke up, erectile dysfunction had become a household word, thanks to the popularity of the drug Viagra. But the widely touted drug, Hanson soon learned, doesn't work for everyone.

You may know horny goat weed from its omnipresence behind the counter at your local convenience store, but this traditional Chinese formula is less sketchy than it sounds. Used for centuries to treat low libido and erectile dysfunction, the herb’s potential efficacy was show in a 2010 study published in the Journal of Sexual Medicine. Researchers who fed the supplement to rats found they had improved erectile function; another study showed that the supplement can block a natural chemical that wilts erections. (Just be warned: Viagra was found to be 80 times more powerful.)
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.
In a study with human subjects, Kruger et al. have reported that acute changes in the normal physiological levels of PRL led to a significantly prolonged ejaculatory latency, but minor reductions of sexual drive and function.[19] Although zinc induced elevation of PRL was not an acute effect, findings similar to the human study (prolongation of ejaculation and mild reduction of libido index with medium dose of zinc) were observed in this study. However, the prolongation of ejaculatory latency may not be merely due to effects of elevated PRL because elevated PRL levels are known to be associated with the negative aspects of sexual activities (decreased sexual desire and frequency of sexual intercourse).[20]

Surgery for erectile dysfunction is usually considered only after all other options have failed. The two surgical options include the insertion of a semi-rigid rod or the implantation of a three-piece inflatable prosthesis. Penile prosthesis implantation has low infection, complication, and malfunction rates. However, since placement of an implant requires permanent injury to the erectile tissue of the penis, implant treatment is considered irreversible.
What are the alternatives to viagra? Erectile dysfunction, when a man cannot achieve or maintain an erection, is a common condition that causes much distress. Viagra is just one of several drug treatments that can help relieve the problem. Other methods and treatments can help, too, including alternative herbal remedies that people may wish to try.

DHEA. Testosterone is essential for a healthy libido and normal sexual function, and erectile dysfunction sufferers known to have low testosterone improve when placed on prescription testosterone replacement therapy. Similarly, studies have shown that taking over-the-counter supplements containing DHEA, a hormone that the body converts to testosterone and estrogen, can help alleviate some cases of ED. But DHEA can cause problems, including suppression of pituitary function, acne, hair loss and its long-term safety is unknown, says McCullough. For this reason, many experts discourage use of the supplements.

In 2015, a meta-analysis of 150 trials determined that while Viagra is the most effective of the various ED drugs on the market, it also has the highest incidence of side effects—things like headache, upset stomach, vision loss or becoming blue-tinged, nasal congestion, back pain, muscle pain, nausea, and dizziness. Another rarer side effect can be having a rock hard erection that doesn't abate—the medical name for this perma-stiffy is called priapism. While priapism might sound appealing to a guy who has been thumbing-in softies for years, it's important to know that an erection that won't go away can cause permanent damage. But we'll get into that in a moment.
"Just because there is evidence doesn't mean it's good evidence," says Andrew McCullough, MD, associate professor of clinical urology at New York University Langone Medical Center in New York City, and one of the original clinical investigators for the ED drug Viagra (sildenafil). "And before men with ED start down the naturopathic route, it's smart to make sure that there isn't some underlying medical condition that needs to be corrected." Moreover, it is estimated that 30 million American men have erectile dysfunction, and 70% of cases are a result of a potentially deadly condition like atherosclerosis, kidney disease, vascular disease, neurological disease, or diabetes. Additionally, ED can also be caused by certain medications, surgical injury, and psychological problems.
The penis contains two chambers, called the corpora cavernosa, which run the length of the organ. Erection begins with sensory and mental stimulation. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the chambers. The inflow of blood creates pressure in the corpora cavernosa chambers, making the penis expand. Erection is reversed when muscles in the penis contract, stopping the inflow of blood and causing the blood in the chambers to flow out.
The power of the mind is not to be underestimated when it comes to believing in remedies so they may sometimes work, even if they do not contain any active substance (this is known as a placebo effect). However, herbal ED remedies offered online can present major health risks. It is important that you understand your treatment options before you take any medication.
What to Tell Your Friend: If our friend's penis was immune to the effects of booze, drugs, performance anxiety, fatigue, or simply not being in the mood for sex, the first thing to do would be to recommend that he go into porn because that's quite a skill set. Then we'd tell him to not waste the money he and his stunt cock earn by spending it on Viagra because he doesn't need it.

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.
Yohimbine: The main component of an African tree bark, yohimbine is probably one of the most problematic of all natural remedies for ED. Some research suggests that yohimbine can improve a type of sexual dysfunction that is linked with a drug used to treat depression. However, studies have linked yohimbine to a number of side effects, which can include anxiety, increased blood pressure, and a fast, irregular heartbeat. Like all natural remedies, yohimbine should only be used after advice and under supervision from a doctor.
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).
Erectile dysfunction obviously can be frustrating, but it can also be an important warning sign of potential heart disease risk. Once you rule that out, there are natural things you can do to improve it. For more information on how to take control of ED, contact Tack180 for a free consultation. Our experts in nutrition, stress management, behavioral psychology, and fitness go beyond the usual counsel to address your particular vulnerabilities.

Many products contain undocumented “fillers” that can cause allergic reactions.  In recent years, the FDA has found over 300 herbal products that contain hidden, deceptively labeled, or dangerous ingredients4. And since 2015, the FDA has released public warnings on more than 160 ED supplements and “male enhancement” products found to contain dangerous ingredients and contaminants5 .   An independent study of FDA data, conducted in 2018, found almost 800 herbal supplements that contained unlisted ingredients6.


Some medical self-help books make niacin sound like a panacea for health-conscious people with rising cholesterol levels and shrinking budgets. Because this B vitamin is cheap and sold over-the-counter at drug and health food stores, people see no reason to check with the doctor before tossing back a handful of pills. What they may not know is that the high doses (1,500-3,000 mg) needed to lower cholesterol levels can cause serious complications. (As a dietary supplement, 10-20 mg is usually recommended). To add to the confusion, niacin comes in two forms: immediate- and sustained-release preparations.
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. 

In conclusion, aerobic training can successfully treat ED in selected patients with arterogenic ED. However, there are very few high-quality randomized trials regarding aerobic training and ED. Practitioners should bear in mind that aerobic training and other risk factors modification is associated with higher rates of ED management success.Since these results are based on small studies, the evidence would be stronger if confirmed by large trials. Effectiveness data were limited; however, the effectiveness of ED is largely determined by the patient health status and associated condition. In addition, work is needed in the standardization of follow-up protocols, evaluation of ED management success and failure, patient selection, and statistical analysis. More randomized studies that compare various exercise techniques are warranted. These studies should evaluate efficacy, complications, quality of life, cost implications, and long-term outcomes of ED management compare to other therapeutic modalities available. Also more database search is also warranted to further broaden the data search on the topic.
In the end, the data from the Hong Kong study suggest that niacin alone can improve the erectile function of subjects with dyslipidemia suffering from ED. This is the first time this conclusion has appeared in the literature. Once again, the effect of niacin is clinically significant in those with moderate to severe ED. Further, because of the close relationship between ED and dyslipidemia, niacin could prove to be an important therapy for managing both conditions. Who knows? There may even be other benefits. Future studies will further refine the indications and benefits of niacin in patients with ED.
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.
Older age. A man’s risk increases past the age of 40, as age is the variable most strongly associated with impotence. This is due to changing hormones, higher risk for heart problems and those affecting circulation, and decreased sexual desire that often occurs with increasing age. For example, based on findings from the National Health and Social Life Survey, it’s been found that “men between 50–60 years old are more than 3 times as likely to experience erection problems and to report low sexual desire compared to men aged 18 to 29 years.” (3)
It’s hard to concentrate on what’s happening in the bedroom when you’re thinking about problems at work. For many men, it’s psychological issues like anxiety rather than physical ones that contribute to E.D. Chronic stress has also been linked to heart disease, high blood pressure, depression, and more. Find a way of blowing off steam that works for you (I like exercise and meditation) and stick to it.
The Scenario: Driven by an urge to be the best he can be, a friend who does not have erectile dysfunction is pre-gaming for sex by taking Viagra recreationally. He maintains that the erections he sports while taking it are fuller, harder, and more long lasting than the ones he produces naturally and help overcome a slew of obstacles that can bedevil his boner including too much booze, cocaine, performance anxiety, and the fact that he's long past the days when a stiff breeze would be enough to provoke a thumping erection. He's also been known to take it when he's not necessarily in the mood for sex but doesn't want to disappoint a horny partner.

But, first for those of you who do not know anything on this topic, let’s define erectile dysfunction. Erectile dysfunction is a condition which characterizes itself with the inability to maintain an erection during sexual intercourse. Luckily, although erectile dysfunction is a common condition, this condition seems to be easily treated. You can choose from the variety of natural remedies, including supplements, which claim to increase your stamina, sexual ability, and muscle mass. This article is dedicated to the importance of exercise as a way to treat erectile dysfunction and highlight the best exercises you could use as a part of the treatment. 
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.
