Generally, erectile dysfunction (ED) is a neurovascular condition directly involving the endothelium of the corpora cavernosal arterial blood vessels in the penis, and is indirectly linked to cardiovascular diseases. The underlying mechanisms of ED are, however, complex and involve psychogenic, neurogenic, hormonal and vascular factors. ED occurs in aging men, with a prevalence of 52% in men 40 to 70 years of age [1-3]. Conditions that may cause ED include hypertension, diabetes, diseases of the prostate and heart, and obesity. ED may also be caused by the effects of certain medications as well as physical injury or anatomical deformity of the penis , or may result from endocrine disorders such as low testosterone, hypogonadism, adrenal insufficiency and hypothyroidism. Changes in blood flow to the male reproductive organs as a result of hardening of the arteries or atherosclerosis, hypertension and hypercholesterolemia may result in ED. It is generally accepted that there are vascular and neuropathic components to the pathophysiology of the disease, and ED has been recognized as a potential indicator of underlying cardiovascular disease. Chronic infections and/or inflammation of the prostate and irritation of the bladder may contribute to the pathogenesis of ED.
Shape up. Because ED is often linked with restricted blood flow to the penis, keep your heart and arteries in good condition by maintaining a healthy weight, and following a diet high in fruits, vegetables and whole grains. Avoid saturated fats and trans fats. Regular aerobic exercise can improve blood flow to the genitals and reduce any stress that contributes to your ED.

Erectile dysfunction, sometimes, which also may imply to refer to “impotence,” is the repeated inability to get or keep an erection firm enough for sexual intercourse23,34. The word “impotence” may also be used to describe other problems that interfere with sexual intercourse and reproduction, such as lack of sexual desire and problems with ejaculation or orgasm23. Roper29 defines erectile dysfunction as the total inability to achieve erection, an inconsistent ability to do so, or a tendency to sustain only brief erections (premature ejaculation). Pamplona-Roger27 defines impotence as the inability to finish sexual intercourse due to lack of penile erection. These variations make defining ED and estimating its incidence difficult. For purposes of this publication, since ethnobotanical indigenous knowledge (IK) cannot clearly distinguish between these two terms, then erectile dysfunction and sexual impotence are both used. The local people who are providers of this information are not in position to classify these two conditions.
A variety of personal habits and lifestyle choices have been linked to ED. In some ways, this is a good thing, since habits can be broken and choices reconsidered. What's more, many of the lifestyle factors that contribute to sexual problems are ones that affect overall health and well-being, both physical and mental. Addressing these factors, therefore, can have benefits beyond improving erectile dysfunction.
The basis of ED herbal therapies is that they are anti-inflammatory, antioxidant and immunomodulatory, and can stimulate testosterone production. On the other hand, the synthetic drugs act via NO. The principal mediator of the relaxation of corporal smooth muscle of the penis has been shown to be NO, which is released mainly from parasympathetic nerves and endothelium . NO is believed to relax the corporal smooth muscle by activating soluble guanylate cyclase to increase cGMP content [14,15]. Penile rigidity depends on maximizing inflow of blood while minimizing outflow . The increased blood flow in the cavernous sinuses puts pressure on the walls of the surrounding veins, causing the lumen of the veins narrow, temporarily interfering with the flow of blood but causing tumescence. Normally, the parasympathetic nerve produces Ach. Ach acts on muscarinic receptors and nicotinic cholinergic receptors. When the parasympathetic nerve is stimulated, preganglionic neurons release Ach at the ganglion, which acts on nicotinic receptors on postganglionic receptors. Postganglionic neurons then release Ach to stimulate muscarinic receptors of the target organs. The muscarinic receptor M3, present in the endothelial cells and smooth muscle, is activated, and the M2 receptor in the heart may also be activated. This may result in the production of Ach, which can cause endothelial cells to produce NO. Ach released from postganglionic parasympathetic nerves acting through G-protein-mediated muscarinic receptors and nicotinic cholinergic receptors helps to release NO. Normally, M1, M2 and M3 receptors are found in secretory glands, heart, smooth muscle and endothelial cells, respectively. M1, M2 and M3 receptors cause activation of phospholipase C and generate inositol trisphosphate and diacylglycerol, which increase calcium. Activation of M4 may inhibit adenylate cyclase, decreasing the messenger cyclic AMP. This mechanism may be involved in the relaxation and contraction of cavernosal smooth muscle cells.
L-arginine is used by the body to increase and precursor to the production of human growth hormone, prolactin and several amino acids It even increases our sensitivity to insulin, analogously to body when we exercise, by accepting more glucose to enter into our cells and improve better cellular energy therefore less fatigue with much more stamina. L-arginine’s function in supporting our metabolic health are also extremely important for building stronger muscle tissue and potentially to help fight inflammation.

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.
Therefore, this particular study was carried out purposely to document medicinal plants used by traditional medical practitioners to treat ED and sexual impotence and other male erectile related conditions in western Uganda. This manuscript only covers the ethnobotanical documentation of medicinal plants used in the management of erectile dysfunction excluding the socio-cultural aspects. The socio-cultural aspects in details will be presented in the next manuscript covering the broad range of reproductive health ailments management using the indigenous knowledge in western Uganda.
Much of the evidence shows high rates of vitamin D deficiency in patients with erectile dysfunction. In fact, one study of 3,400 participants found that men with vitamin D deficiency were 32% more likely to have trouble with erections when all other risk factors were controlled for. It’s a little on the nose that you need vitamin D for your “D,” but hey—science can be funny too.
Wild oats: a study in 1986 by the Institute for Advanced Study of Sexuality in San Francisco reported effects like heightened sexual awareness, increased sexual thoughts, more orgasms (36% in men and 29% in women) and some male subjects showed increased levels of testosterone attributed to unbinding of testosterone from TBG. Oats supply steroidal saponins which modulate hormonal balance (5).
Erectile Dysfunction is extremely common in men and the number one herb to treat and heal erectile dysfunction is no doubt Tongkat Ali. The herb is commonly known as Malaysian Viagra or Natural Viagra even Herbal Viagra is known to be the best natural male herb, making it extremely valuable herb to restore manhood, virility and libido plus erection. It stood the simple test, most lab evidence and experience from uses attest to its benefits vs Viagra like drugs.

Researchers at Johns Hopkins University last year looked at 3,400 healthy Americans and found that men who were vitamin D deficient were 32% more likely to have trouble getting it up than those with sufficient levels, even after adjusting for other ED risk factors. In fact, the connection is so common, Walker says D levels are something he always checks in ED patients. Why? The sunshine vitamin is crucial for keeping the endothelial cells that line blood vessels healthy. Without enough of the stuff, blood flow is inhibited, affecting everything from your heart to your hard-on.
