In one study, men with a Vitamin D deficiency were nearly 33% more likely to have ED. But you don’t need that much sun exposure to get a healthy amount of Vitamin D. As little as 15–20 minutes a day is enough. Taking Vitamin D is a good idea, especially if you are over 65. Vitamin D can also help if you’re obese or dark-skinned (dark skin limits the amount of Vitamin D you naturally, produce)
The proved herbal remedies with therapeutic values such as Prunus africana used in the treatment of hypertrophy in male genitalia is indicative that some herbals may be potent though not yet studied comprehensively5,13. However, most of the herbal remedies used in male ailments are not well documented and researched. The dangers of loosing valuable indigenous knowledge (IK) on sexual impotence and ED are likely to occur because westernization in the present generation. This indigenous knowledge in medicine ought to be documented for future use and sustainable utilisation19. According to the convention on biological diversity (CBD)6, specific reference is made to the need to protect the world's indigenous cultures and traditions (Art. 8 of CBD). This article points out that national legislation need to respect, preserve and maintain knowledge, innovations and practices of indigenous and local communities encompassing traditional life styles relevant for the conservation and sustainable use of biodiversity. UNEP argues nations to have an urgent action to safeguard indigenous cultures and their knowledge.
^Effects of Korean ginseng berry extract on sexual function in men with erectile dysfunction: a multicenter, placebo-controlled, double-blind clinical study. - Author: Department of Urology and Urological Science Institute, Yonsei University College of Medicine, Seoul, and R&D Center, Amorepacific Corporation, Gyeonggi-do, South Korea (20 Dec 2012)
Long considered an aphrodisiac by the Chinese, ginseng may do more than just rev your engine. A 2013 South Korean study found that taking the herb for just a few weeks improved guys’ performance in the bedroom, including helping them last longer before finishing. Meanwhile, a study in Spermatogenesis found that ginseng can also help make for harder, longer-lasting erections and improve testosterone levels, which in turn boosts libido. “Ginseng is a promising herbal therapy for ED because it helps promote relaxation of smooth muscle in the penis, increase dopamine levels in the brain, and increase pressure in the cavernosal nerves of the penis which helps nitric oxide synthesis,” Walker explains.
Despite the name, horny goat weed actually helps improve your erection, not libido. Botanically known as epimedium, this herb has been used by the Chinese for centuries to treat, among other things, low libido and erectile dysfunction. “A growing body of research shows that isolated icariin—the extract of epimedium—inhibits the enzyme phosphodiesterase-5 (PDE-5) and significantly increases nitric oxide synthase, helping to improve erectile function,” says Fisch. In fact, this is the same mechanism that Viagra works through (but the herb comes with a way better name).
Poor sleep patterns can be a contributing factor for erectile dysfunction, Mucher says. One review published in the journal Brain Research emphasized the intricate relationship between the level of sex hormones like testosterone, sexual function, and sleep, noting that testosterone levels increase with improved sleep, and lower levels are associated with sexual dysfunction. Hormone secretion is controlled by the body’s internal clock, and sleep patterns likely help the body determine when to release certain hormones.
Nitric oxide is made internally from L-arginine, which is an amino acid found in red meat, poultry, fish, and dairy products. In other words, L-arginine is the building block for nitric oxide, which is essential for erections. A lack of one can lead to a lack of the other. However, there’s a problem when it comes to treating L-arginine deficiency with supplements.
Ginkgo biloba may increase blood flow to the penis. Researchers discovered the effect of gingko on ED when male participants in a memory enhancement study reported improved erections. Another trial saw improvement in sexual function in 76 percent of the men who were on antidepressant medication. This is why researchers believe that ginkgo may be effective for men who are experiencing ED due to medication.
Other factors that “stress” the body can also increase your risk for ED. These include: substance abuse, using marijuana, smoking cigarettes, depression, anxiety and low self esteem. Cigarette smoking — or using nicotine — leads to constricted blood vessels, which has negative effects for sexual health. Other mental/emotional obstacles can cause less desire for sex and decrease testosterone. Several ways to help manage stress include:
The neurovascular mechanism of erection is complex and involves multiple factors including hormones, neurotransmitters, elements of the autonomic nervous system (sympathetic and parasympathetic) and vasodilators such as NO. The common causes of ED include psychogenic disturbance with failure to relax cavernous smooth muscle, arterial insufficiency as a result of atheromatous disease, damage to the parasympathetic nervous system, spinal cord injury, diabetes or following pelvic surgery such as radical prostatectomy, radical cystectomy or bowel resection . It is important to note that cavernous nerves are unique in that although they belong to the autonomic nerves system they do not release either acetylcholine (Ach) or norepinephrine; however, they release NO in the penis. NO relaxes the smooth muscle of the corpora cavernosa via cyclic GMP (cGMP), allowing expansion of the cavernosal lacunar spaces, blood flow and erection. Thus, NO is not a direct dilator of the smooth muscle of cavernosal bodies, but it is an important mediator in this process. Erectile function may also be adversely affected by cigarette smoking, excess alcohol consumption, obesity and systemic diseases such as mononucleosis, hepatitis, HIV and cancer. Some men are prone to develop an erection that fails to subside after ejaculation (ie, priapism). The condition is associated with sickle-cell disease and leukemia, or may be a result of intracavernosal injection of drugs such as prostaglandin E1 . Peyronie’s disease causes a physical bend in the erect penis and also contributes to ED.
The field visits and excursions were arranged with the healers for places far from their homesteads or took place concurrently with the interviews and discussions. When going to the forests, game reserves or other areas where herbalists collect plant specimens, prior arrangements were made with the community leaders and park staff. This was done with individuals or groups depending on where the herbs are collected. In the shared areas such as the fishing villages, or the multiple use areas, group and individual excursions were conducted. Some of the medicinal plants that are harvested from distant places such as the Democratic Republic of Congo, other districts and unsafe areas within the reserve were not collected but their local names were recorded. The data collected were to supplement the information on plant names, plant parts used, collection of the herbarium voucher specimens and conservation status of these medicinal plants. The medicinal plants collected were given the voucher numbers and then later identified in Botany Department herbarium of Makerere University.
Currently, there are four orally active drugs are available to treat ED. These include: sildenafil citrate (Viagra [Pfizer, USA]), vardenafil hydrochloride (Levitra [Bayer, Germany]), tadalafil (Cialis [Eli Lilly, USA]) and avanafil (Stendra, Spedra [Vivus Inc, USA]). These drugs inhibit the enzyme phosphodiesterase type 5 (PDE-5), which is responsible for the hydrolysis of cGMP. PDE-5 inhibitors and cGMP act as effectors of dilation of smooth muscle of cavernosal bodies. PDE-5 inhibitors are contraindicated in patients taking any kind of nitrate therapy for angina, and may not be appropriate for men with certain health conditions, such as severe heart disease, heart failure, history of stroke or heart attack, uncontrolled high blood pressure or diabetes, and patients with pigmental retinopathy. PDE-5 inhibitors are less effective in men with diabetes and men who have been treated for prostate cancer. PDE-5 inhibitors are also not effective in men with retinitis pigmentosa, a genetic disease involving PDE-5 deficiency. The common side effects of PDE-5 inhibitors include gastrointestinal upset, headache, nasal congestion, back pain and dizziness. The PDE-5 inhibitors may interact with other medications including antihypertension drugs. Nonetheless, the PDE-5 inhibitors are generally safe and effective for most men. The primary mechanism of action of these drugs is through the mediation of NO. NO is one of the key molecules involved in ED. It is a short-lived, highly permeable, pleiotropic, gaseous molecule, secreted from the postganglionic cavernosal parasympathetic nerves, endothelium of the cavernosal blood vessels, platelets in the cavernosal sinuses and phagocytic cells (monocytes, macrophages and neutrophils). NO acts on platelets to inhibit platelets adhesion and aggregation. NO causes relaxation of the smooth muscle of the cavernosal blood vessels of the penis, leading to vasodilation, tumescence and stimulation. Release of NO in the corpus cavernosum of the penis during stimulation activates the enzyme guanylate cyclase, which results in increased levels of cGMP, producing smooth muscle relaxation in the corpus cavernosum and resulting in increased blood flow (5). NO is mainly produced from cavernosal nerves, which are nonadrenergic, noncholinergic nerves within the penis, and acting via its second messenger cGMP. It has been suggested that maintaining normal body weight and mild exercise, as well as dietary supplementation of folic acid, zinc, calcium, vitamin C, vitamin E and L-arginine, a precursor of NO, can support the biochemical pathway leading to NO release . NO is an effector molecule that is involved in a number of intracellular functions such as vasorelaxation, endothelial regeneration, inhibition of leukocyte chemotaxis and platelet adhesion . A small proportion of autonomic nerves do not release either Ach or norepinephrine . For example, the cavernous nerves predominantly release NO in the penis. The exact mechanism is not known, but it is believed to be through increased intracellular calcium. Another gaseous molecule produced in the corpora cavernosa is hydrogen sulphide (H2S), which is also known to be involved in erectile function . H2S activates ATP-sensitive potassium channels in smooth muscle cells. Some reports indicate that NO acts in large vessels and H2S in small vessels. A high level of tumour necrosis factor-alpha has been shown in ED patients . Although current ED therapies using PDE-5 inhibitors are safe and effective, approximately 40% of ED patients do not respond to currently available treatment [11,12]. For these patients, herbal therapy may be useful.
Animal testicles: derived from bulls and wild boars, the orchic substance has been used as a way to possibly increase testosterone levels and sperm counts. In Singapore, testis soap was once very popular (Figure 2). It is still sold in parts of China and Japan. The dried Dog testis and penis (canis familiaris) is believed to tonify the kidneys and strengthen the yang II. Kidney deficiency is believed to be the cause of impotency in Chinese literature.
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).
Ashwagandha (Withania somnifera), used widely in Ayurvedic medicine, holds a similar role to that of ginseng in Chinese medicine. Though unrelated to ginseng, it appears to share similar properties and actions. Ayurveda considers this herb to be a rasayana, or particularly powerful rejuvenative. The name ashwagandha means “like a horse,” connoting that it is regarded as a premier sexual tonic.
The key respondents were mainly old men, male traditional healers, traditional birth attendants and young women and all in total about 160 traditional healers were interviewed. To document male related ailments men are particularly more knowledgeable and most men share their problems with men. In addition, the old men and healers are the ones in charge of administering these herbal remedies. Young women through the informal discussions, interviews and market surveys are particularly more dynamic in the use of herbs for themselves, husbands and children besides being the most active reproductive age group. The medical ethnobotanical data collected has been analysed, medicinal plants from the study areas have been listed and methods of administering the herbal drugs were also documented. In checking for the proper updated naming, spellings and authors of the medicinal plants, besides using voucher specimens in Makerere University Herbarium, several reference books were used1,3,9,15,16,20,22,27.
The Plant: It’s true, the name’s hilarious. But as it turns out, it’s not just one plant: supplement manufacturers might put any one of 15 different species from this genus of shade-loving perennials inside that pill. That’s important to keep in mind, because the types and amounts of biologically active molecules the plant contains can differ from species to species.
If you have symptoms of ED, it’s important to check with your doctor before trying any treatments on your own. This is because ED can be a sign of other health problems. For instance, heart disease or high cholesterol could cause ED symptoms. With a diagnosis, your doctor could recommend a number of steps that would likely improve both your heart health and your ED. These steps include lowering your cholesterol, reducing your weight, or taking medications to unclog your blood vessels.
