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]
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.
When it comes to maintaining your libido, the B vitamins, found in beef, liver, and fish, are all your wingmen, but niacin (a.k.a. Vitamin B3) is especially helpful. In a study published in the Journal of Sexual Medicine, men suffering from impotence who took a niacin supplement reported a significant improvement in their bedroom performance than men who took a placebo. Stock up on these best foods to eat for niacin!
Regardless of diet or exercise - to control a sexual act, it's imperative to balance your sexual focus during foreplay, penetration, and intercourse. When you feel safe throughout foreplay it's easy to penetrate and if you're not worried at penetration time then intercourse is easier. A happy and satisfying sex life is knowing when and where to put your attention. How to do this is explained step-by-step in my Sex Mastery Hard AND in Control program for men.
Long prescribed for women who want to restore muscle tone after childbirth, pelvic floor exercises, also known as Kegel exercises, can benefit men significantly too. A study by researchers at the University of West of England in Bristol showed that pelvic floor exercises can help men with erectile dysfunction and premature ejaculation. Furthermore, experts think these exercises can make orgasms stronger. Once learned, pelvic floor exercises can be done any time, even while doing other things.
One study that evaluated the effects of yohimbine supplementation on body composition (muscle mass, body mass, etc.) and exercise performance in professional soccer players found that body fat percentage/fat mass significantly decreased in the yohimbine group compared to the placebo group. However, supplementation with yohimbine did not significantly alter overall body mass, muscle mass, or performance indicators. (10) Other studies, however, have found that people do tend to experience increases in energy and alertness when taking yohimbe, sometimes even so much that it causes symptoms of anxiety or restlessness (much like caffeine does).

Aerobic exercises and pelvic floor exercises are two of the best methods to start with. As a matter of fact, you can see improvements on your condition without having to witness the side effects of other male enhancement products. For one, there are certain male enhancement products which should not be taken if you are suffering from other types of medical condition. For instance, if the product contains substances that may react to the male enhancement ingredients of a product, you may suffer from certain consequences.
The researchers noted that "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...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. Niacin alone can improve the erectile function in patients suffering from moderate to severe ED and dyslipidemia." [3]
How it works: Rhodiola works in supporting our adrenal glands by preventing the breakdown of too much dopamine and serotonin during stressful times, leaving enough for us to remain buoyant and energized. What’s extra fun about Rhodiola is that it works fast – in 30 minutes – to change your energy levels and focus – so pop one before you think you want to get frisky.
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:

In the end, open and honest communication with your therapist will yield the best course of action. If you do decide to try pelvic floor PT, a comprehensive evaluation will determine what exactly is going on with your muscles. They may be tight and weak or they could have poor coordination. So my advice for those suffering from erectile dysfunction is this: before you try kegels, make an appointment with your pelvic floor therapist.
Yohimbe is an herbal remedy that comes from the bark of an African tree, Pausinystalia yohimbe. Before Viagra, drugs containing yohimbine hydrochloride, the active ingredient in yohimbe bark extract, were used to treat erectile dysfunction (ED). However, levels of yohimbine in yohimbe bark extract vary considerably and are often very low. Yohimbe bark extract, by itself, never has been shown to work as effectively as drugs containing yohimbine hydrochloride. What’s more, yohimbe can have serious side effects including paralysis, fatigue, stomach disorders, even death. I don’t recommend it, and harvesting of its bark is driving the yohimbe species to extinction.
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).

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.)
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.
Moreover, it has a positive effect on the nervous system, liver, skin, and mucous membranes, as well as keeps skin, nails, and hair healthy. And of course, what is important for men, erectile dysfunction treatment with vitamin B2 relieves symptoms of the most hateful male disease. Moreover, this vitamin is well-known as a supplier of sexual energy and vitality.
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.
It's also important to remember that your mental health plays as much a part of your sexual ability as your physical health. Stress and other mental health concerns can cause or make erectile dysfunction worse. Minor health problems may slow your sexual response, but the accompanying anxiety that comes with the slow sexual response can shut things down entirely.
This is one B team you want to get on pronto: A recent report from Harvard University highlighted a study that has linked low levels of B12 to erectile dysfunction. A causal link hasn’t been nailed down, but the B vitamin is used by every system in the body, particularly in cell metabolism and the production of blood — two essential factors in getting and keeping a quality erection.

Those looking to crank up their body's fat-burning to the next level may stack yohimbine HCL with ephedrine HCL and caffeine, creating the ECY stack. Yohimbine is a powerful stimulant that acts on different metabolic pathways compared to caffeine and ephedrine. The most common dosage for each compound in this stack is 5mg of yohimbine HCL, 200mg caffeine, and 25mg ephedrine HCL two to three times per day.
Could the bark of a tree actually increase libido and improve impotence? Well yes it can… Yohimbe bark (Pausinystalia yohimbe), one of the most popular herbal remedies for male sexual dysfunction, has been shown in studies to increase blood flow to the genitals of both men and women, proving to be helpful for those with low libido. Though Yohimbe can be used by women, its actions have been shown to be extremely supportive for men experiencing erectile dysfunction due to stress or as a side effect of physiological health issues.
Aside from pelvic floor exercises, it has been found out that aerobic exercises also work in treating erectile dysfunction. This condition is often caused by problems related to blood flow to the penis. Diabetes, obesity, vascular disease as well as high cholesterol may affect blood flow. This results to erectile dysfunction. By adding some aerobic exercises to your routine, you can significantly enhance your overall male sexual health and may even remove the problem totally in the long run.

Three of the randomized studies (25–27) that contributed to the present study data indicated the positive role of both interval and continuous aerobic training in the dual management of both ED and cardiovascular disorders (hypertension and ischemic heart disease ,respectively); this is not surprising because of the arterogenic interrelationship between ED and several cardiovascular disorders. The physiological basis for the therapeutic role of continuous exercise in the management of both ED and some cardiovascular disorders as reported in the present study, could be related to the biochemical, neural and hormonal changes in the blood vessel walls that induce an acute and long-term blood vessel relaxation. The blood vessels might relax after each exercise session because of body warming effects; local production of certain chemicals, such lactic acid and NO; decreases in nerve activity; and changes in certain hormones and their receptors (32, 33). Over time, as the exercise is repeated, there appears to be a growing evidence of a prolonged effect. Thus, chronic (regular, longterm) physical training might reduce basal concentrations of inflammatory markers.


Ginkgo biloba. Ginkgo is an herb that is used in Chinese medicine that’s thought to improve blood flow. "Any ED treatment that improves blood flow may help," explains Dr. Harris. "An erection is just blood in and blood out." However, the evidence that ginkgo can improve blood flow in ED is limited, and most experts say the jury is still out. In addition, ginkgo can increase the risk for bleeding problems if combined with certain medications, such as warfarin (Coumadin).
Associated risks/scrutiny: “A dose of yohimbine that’s too big could drop your blood pressure, cause dizziness, facial flushing and nausea,” warns Fratellone. Yohimbine and yohimbe bark may also increase heart rate and raise blood pressure. “No one should experiment with herbs without talking to their doctor,” reminds Fratellone. “If you’re taking Flomax and you start taking yohimbe, you’re going to dilate your penal vessels and you’ll pee more.” Other potential interactions between yohimbe and other drugs and herbs should be considered. Some of these combinations may be dangerous.
Eggs a supplement? Yup. Testosterone is derived from cholesterol, and eggs are the healthiest way to ensure you’re getting enough of the good kind (LDL cholesterol). Plus, eggs are rich in choline, a powerful natural chemical that not only burns fat but can help set your pants afire. Choline triggers the production of nitric oxide (NO), which relaxes arteries in the penis and enables blood flow to do its thing. Choline is a precursor to acetylcholine, a neurotransmitter which controls sexual behavior through its activity in the brain; having a higher level of AcH has been associated with more frequent sex and more intense, longer orgasms. And that’s not all: Check out these things that happen to your body when you eat eggs!
In addition to lowering low-density and total cholesterol along with triglycerides, increasing high-density lipoprotein cholesterol (HDL-C) has become one of the principal objectives for treating hyperlipidemia. Considerable evidence has shown that even a minor improvement in HDL-C levels may significantly reduce cardiovascular risk. For example, it has been found that an increase of 1 mg/dl in HDL-C levels results in a parallel reduction in coronary artery disease risk by 2% in men and 3% in women. Moreover, HDL-C helps to transport oxidized cholesterol from peripheral tissues where it instigates atherosclerosis to the liver for excretion. Furthermore, HDL-C has potential anti-inflammatory, anti-thrombotic and anti-oxidant effects.
Niacin -- with or without the addition of drugs to treat impotence -- poses serious health risks, including stomach ulcers and liver damage. If you have Type 2 diabetes, taking niacin could cause drastic elevations in your blood sugar levels. Less serious side effects include stomach upset and skin flushes -- your face and chest turn red and your skin itches, tingles or burns. You can purchase niacin without a prescription, but some over-the-counter formulas -- no-flush varieties that contain niacinamide -- will unlikely help lower your cholesterol.
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
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.
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.
