Thirty two male rats were randomly assigned to four groups and submitted to one of the following daily treatment regimens: (a) 1 mg of ZnSO4 dissolved in 1 ml of distilled water. (b) 5 mg of ZnSO4 dissolved in 1 ml of distilled water (c) 10 mg of ZnSO4 dissolved in 1 ml of distilled water. Controls were provided with 1 ml of distilled water. Supplementation was done orally using a feeding tube. These daily regimens were continued for two weeks (daily at 17.00 hours) and housed two per cage.
It’s traditionally used by Pygmies and Bushmen as an aphrodisiac and stimulant. In the 19th century, German missionaries brought this herbal plant to Europe, where it became known as the “love tree.” The extract of this herb is clear and odorless with a bitter taste, and is traditionally prepared and consumed as a tea. Nowadays, medicines and supplements that contain yohimbe bark are available in capsule and tablet form.

The endothelium is vital to the maintenance of vascular health. It is a critical determinant of vascular tone and patency, reactivity, inflammation, vascular remodeling, and blood fluidity. (9, 10). Nitric oxide (NO) is the most potent vasodilator and is secreted by the endothelium. It is synthesized from Larginine by the endothelial enzyme NO synthase (eNOS). NO released in response to sexual stimulation relaxes penile vascular smooth muscle by increasing intracellular cyclic 3′, 5′-guanosine monophosphate (cGMP) concentration. Vasodilatation of erectile tissues allows the sinusoidal spaces to fill with blood resulting in the attainment and maintenance of an erection (5).
3. Testosterone replacement. Before oral medications like Viagra, testosterone was routinely used to treat erectile dysfunction as it is central in the male sexual response, including the desire for sex and the process of getting an erection. Testosterone can be administered in a number of ways, for example orally, by means of an injection, skin patch, or subcutaneous (under the skin) pellet. 
The appropriate dose of yohimbe depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for yohimbe. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.

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.


Adequate daily magnesium intake is slightly lower for younger men than for those in their 30s and older. The University of Maryland Medical Center recommends 400 mg daily for men between the ages of 19 and 30, and 420 mg per day for men 31 and older. While these levels are a good general guideline, you should check with your doctor to determine the proper dosage for a daily magnesium supplement, particularly if you’re using magnesium to help treat or prevent erectile problems.
Does drinking water improve erectile dysfunction? Erectile dysfunction or ED is a common concern for men. Everyday factors, such as hydration levels, may affect a person's ability to get or maintain an erection. Drinking water may, therefore, help some men with ED. In this article, learn about the link between hydration and ED, and other factors that can cause ED. Read now
For men who do find themselves suffering from ED, the knee-jerk reaction can be to reach for the Viagra but – while ED tablets are an excellent solution in the short term – there are other treatment options to consider incorporating into your lifestyle on a long-term basis, one of the most straightforward being exercise. Below you’ll find four great ways that exercise may help to treat erectile dysfunction.
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.
Does diabetes cause erectile dysfunction? Diabetes can lead to lower levels of testosterone, and this can result in erectile dysfunction. Controlling blood sugar levels, maintaining a healthy weight, getting exercise, and reducing stress are all ways of reducing this problem. Hormone therapy, Viagra, and counseling are some ways that medicine can help. Read now
Yohimbine hydrochloride is the principal alkaloid of the bark of the African yohimbe tree. It is primarily selective for the presynaptic alpha-2 receptor that enhances the central release of norepinephrine1,2 or even epinephrine,3 although the latter is controversial.4 This central action increases sexual arousal2,5 and appears similar to the central alpha-2 adrenergic mechanism that initiates hot flashes.6 Peripherally, yohimbine may partially antagonize norepinephrine-induced contraction of corporeal cavernosal smooth muscle.7,8 The action is that of an antagonist to postjunctional alpha-2 adrenergic receptors, but a direct effect on vascular smooth muscle is also possible.9
Yohimbe supplements haven't been tested for safety and keep in mind that the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. You can get tips on using supplements here, but if you're considering the use of Yohimbe, it is essential that you talk with your physician first. 
In male rats, main olfactory epithelium (MOE) exerts an important role in regulating sexual behavior. Intranasal irrigation with zinc sulphate has been reported to destroy the MOE and completely abolish the sex behavior.[6] In this study supplementation of zinc was done using a feeding tube and precautions were taken to avoid contacting nasal area. Hence the possibility of reducing sexual performance due to MOE disturbance is ruled out. Some humans experience gastrointestinal irritation with supplementation of zinc.[23] If the same is applicable to animals it may be another possible explanation for the reduction of libido index with elevated doses of zinc. One drawback of our study is that we did not compare the weight of animals before and after treatment.
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.

Yohimbe has been shown to be an alpha-adrenoceptor blocker. This action reduces the effects of hormones that increase the constriction of blood vessels as a person ages. Yohimbe also increases production of norepinephrine, which plays a role in achieving erection during sexual arousal. Yohimbe increases the amount of adrenaline that reaches the nerve endings, enhancing sexual sensations and allowing for a more satisfying sexual experience. Yohimbe has been shown to support sexual longevity.
In the human body, folic acid interacts with vitamin B12, pantothenic acid, and vitamin B7 (also called vitamin H or biotin). The signs of biotin deficiency can be hair loss, skin inflammation, skin pallor, mucous membrane inflammation, depression, drowsiness, anemia, blood sugar disorders, muscle pain, poor appetite, nausea, and insomnia. Besides, a person feels tired, irritable and depressed. Consequently, male libido and sexual activity reduce. In turn, this negatively affects sexual performance.
The final study we will be examining in this article took a novel approach to by dosing 16 healthy male subjects with 7.7 milligrams of yohimbine tartrate and 6 grams of L-arginine glutamate and comparing it to a placebo. Depending on their group each subject was randomly assigned to consume the placebo one week and the novel compound the other week.
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.

Move a muscle, but we're not talking about your biceps. A strong pelvic floor enhances rigidity during erections and helps keep blood from leaving the penis by pressing on a key vein. In a British trial, three months of twice-daily sets of Kegel exercises (which strengthen these muscles), combined with biofeedback and advice on lifestyle changes — quitting smoking, losing weight, limiting alcohol — worked far better than just advice on lifestyle changes.
DHEA. DHEA, or dehydroepiandrosterone, is a natural hormone that the body uses to make the male hormone testosterone. DHEA and testosterone decrease with age, just as ED increases with age, so it seems that taking DHEA might protect against ED. But Harris says that "it is unlikely that taking DHEA would raise your testosterone enough to make much difference." DHEA should not be used by people with liver problems; it also has many side effects.
b) Men With Digestive Disorders.  There are many, many GI disorders that plague modern, urban dwellers:  atrophic gastritis, Crohn's, diverticulitis, enzyme deficiencies, IBS, ulcerative colities and on and on.  All of these can lower vitamin and mineral absoprtion.  Men struggling with these issues may very well benefit from increased amounts of niacin in the diet or possibly with supplementation.
Male erectile dysfunction (ED) has been defined as the persistent inability to attain and/or maintain an erection sufficient for sexual performance (1). ED is very common, and its prevalence as well as severity increases with age (2). It has been recognized that the major cause of ED is atherosclerosis affecting the pelvic vasculature (3). The presence of ED has been known to predict future cardiovascular disease, and early detection may allow timely modification of remediable risk factors, or lead to the diagnosis of occult cardiovascular disease (4, 5).
