Deer antlers (Cervi pantotrichum): the most popular of sexual tonics. In the Chinese medical teaching, kidneys control sexual function; hence foods and herbs such as this can invigorate impotency and infertility increasing semen production as well (5). Best quality are from young bucks with new horn still in velvet with blood visible in the cartilage.
ED may occur at any age, but tends to have a greater psychological effect when it occurs in midlife. ED invokes stress related to midlife intimacy and the physiological realities of aging. Although the prevalence of ED increases with age, it is not an inevitable consequence of aging. Rather, ED becomes more prevalent as men grow older because of its relationship with various age-related diseases. Several studies have found that age is an independent risk factor for severe ED, even after adjustment for other age-related diseases. The aging male requires more penile stimulation; it takes longer to get an erection and the erection may not be hard enough for vaginal penetration. Also, it takes more time to reach ejaculation in elderly individuals. Absence of sexual interest in the partners of older men can lead to ED simply by the man not receiving sufficient direct penile stimulation. Testosterone replacement therapy for aging men has become a topic for discussion among health care providers. There are no established norms for testosterone levels in aging men. Studies in healthy men show that testosterone levels, particularly free bioactive testosterone levels, decline with age although there is considerable interindividual variation. The percentage of men who actually become ‘testosterone deficient’ is unknown. The diagnosis of androgen deficiency in aging men is associated with a wider range of symptoms than a mere impact on hormone levels per se. If the patient has no clinical signs of an androgen deficiency, testosterone replacement therapy will have no clinical effect.
Although there are few men who are born absolutely impotent, the number of men with erectile problems are many especially those tending to 50 years and above. Pfizer28 reported that about 40% of men above years, 50% of men above 50 years, 60% of men above 60 years and in any population are affected by ED. ED has profound effect on psychological well being, it can be devastating, it can lead to low self-esteem, depression, negative effect on relationships and reduced life satisfaction28. Among several other causes, aging is one of the factors leading to ED. There are some other social causes of ED such as high unemployment rates, and diseases like diabetes, hypertension, HIV/AIDS, high cholesterol levels, stress, smoking and obesity28. ED is slowly creating adverse problems in homes in Uganda and particularly, among the mid-aged and old men. The men with sexual impotence and erectile dysfunction deserve proper diagnosis of the conditions and treatment. Thus, the plant remedies described may be healthy if administered
Pay attention to your vascular health. High blood pressure, high blood sugar, high cholesterol, and high triglycerides can all damage arteries in the heart (causing heart attack), in the brain (causing stroke), and leading to the penis (causing ED). An expanding waistline also contributes. Check with your doctor to find out whether your vascular system — and thus your heart, brain, and penis — is in good shape or needs a tune-up through lifestyle changes and, if necessary, medications.

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 [13]. 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 [6]. 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.
Tribulus Terrestris is the fruit of the Zygophyllaceae plant and it grows primarily in North China. It is a well-known aphrodisiac with records that trace back to ancient times. There are plenty of animal experiments that verify the effectiveness of Tribulus for improving erectile function. These effects are mostly due to its androgen enhancing ability, namely increasing testosterone levels. Though testosterone doesn’t directly cause an erection, it does play a role. Erection is made possible by many factors, but mostly it's through receptors on cells lining our arteries that stimulate a chain reaction that relaxes the blood vessels that go to the penis, allowing blood flow to get in. Low testosterone is often associated with overall poor metabolic and cardiovascular health. When the test is low, estrogen is usually high, leading to oxidative stress and calcification of the arteries, including the penis, restricting blood flow to the penis. So, improving testosterone levels, and improving overall metabolic function, while reducing oxidative stress is a good plan for improving overall sexual function and erection.
Pomegranate juice. Drinking antioxidant-rich pomegranate juice has been shown to have numerous health benefits, including a reduced risk for heart disease and high blood pressure. Does pomegranate juice also protect against ED? No proof exists, but results of a study published in 2007 were promising. The authors of this small-scale pilot study called for additional research, saying that larger-scale studies might prove pomegranate juice's effectiveness against erectile dysfunction. "I tell my patients to drink it," says Espinosa. "It could help ED, and even if it doesn't, it has other health benefits."
How common is impotence? According to findings from several studies, including “The Massachusetts Male Aging Study,” overall prevalence for men between 40–70 years old is around 52 percent (or around 30 percent of all men between 18–60 years old). That’s right — nearly half of all men over 40 experience erectile dysfunction symptoms at some point. Not surprisingly, research demonstrates that impotence is increasingly prevalent with age. Around 40 percent of men in their 40s experience sexual dysfunction. Up to 70 percent of men in their 70s experience ED. (1) Every year more than 617,000 new cases of impotence occur in the United States alone.
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.
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. 
There is no single cause for erectile dysfunction. Achieving an erection involves a complex series of physiological events; in order for an erection to occur, the body is required to coordinate nervous system responses with tactile sensations, emotional triggers, and signals from certain hormones. If any of these events are disrupted, impotence is likely to occur.

A study published in May 2014 in The Journal of Sexual Medicine found that some men can reverse erectile dysfunction with healthy lifestyle changes, such as exercise, weight loss, a varied diet, and good sleep. The Australian researchers also showed that even if erectile dysfunction medication is required, it's likely to be more effective if you implement these healthy lifestyle changes.
These medications don’t work for everyone but they are easy to use and work for around 60% of people who try them. They work by making it easier to get an erection by reducing the effect of (inhibiting) the chemical PDE-5. This chemical is used in the body to make sure there isn’t too much blood in the penis during an erection, but if you have erectile dysfunction then this chemical ends up over-compensating.

There’s no bedroom bummer quite like having to fly at half mast, but your penis problems are likely more common than you think: As many as 30 million American men suffer from erectile dysfunction, and one in four who seek treatment for ED are actually under the age of 40, according to a study in The Journal of Sexual Medicine. We all know there’s a little blue pill that can fix the failure to launch—but you don’t necessarily have to fill a ‘script to save your stiffy.
Vitamins and minerals are used in systems all over the body. Everywhere from your cardiovascular to your nervous system. It’s a lot to understand. So to help dispel some of the myths and outlandish claims, we’ll take a look at how five common vitamins and nutrients affect one very specific aspect of men’s health—erections. Turns out, vitamins can do more than just ward off the common cold.
In the East, many herbal tonics and preparations are used to assist the aging male improve his sexual drive or ability to perform penetrative sex by increasing sexual stimulation, erectile, ejaculatory, orgasmic and other responses for sexual function and satisfaction. The herbs and tonics act as or as “pick-me-ups” and energizing tonics which help the tired and fatigued male and those with sexual asthenia. The myths and realities concerning Tongkat Ali, sea horse, cobra meat and blood, animal penises and testicles amongst many other herbs and portions for oral intake or local application used by traditional “medical” practitioners and village doctors will be discussed.
The Science: Chemicals inside these plants called ginsenosides are thought to ramp up the physiological pathway that makes nitric oxide, the neurotransmitter that gets the blood flowing during penile erection. Some studies support that idea: one found that ginsenoside-rich ginseng berry extracts relaxed smooth muscle inside rabbit erectile tissue. But so far there haven’t been high-quality double-blind and randomized trials of the chemicals’ effect on humans. The jury’s still out on whether ginsenosides have any effect on people at all, or (if they do) whether they work as well as medications like Viagra.

Ashwagandha’s reputation as a sexual enhancement herb is supported by research. One animal study showed that extracts of ashwagandha increased production of sex hormones and sperm, presumably by exerting a testosterone-like effect. In another clinical trial, the herb (taken at a dose of 3 gm per day for 1 year) was given to healthy male adults 50–59 years of age. Among benefits noted: serum cholesterol levels decreased, gray hair was reduced, and a vast majority (over 70%) reported improvement in sexual performance.
The estimated range of men worldwide suffering from ED is from 15 million to 30 million23. According to the National Ambulatory Medical Care Survey (NAMCS), for every 1,000 men in the United States, 7.7 physician office visits were made for ED in 1985. By 1999, that rate had nearly tripled to 22.3. This is in USA, where statistics are clearly compiled, the level of awareness and education is high as compared to sub Saharan countries like Uganda. This is a clear indication that there are many silent men, particularly couples affected by ED.

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.

Historically, it has been shown that herbal medicines may cure or prevent certain ailments. However, there are very little recorded data available to support the dose, efficacy, side effects and interactions. Because the safety and efficacy of herbal remedies have not been assessed, unlike synthetic drugs, well-controlled and randomized studies are warranted to establish the therapeutic efficy and safety of such products. Determination of side effects and interactions with prescription medicines are also needed. The amount of active ingredients in herbals may vary among preparations; thus, standardization of herbal medicines is required.
Some natural viagra supplements have been shown to increase nitric oxide levels and increase blood flow to the penis. But there are no true natural alternatives to prescription ED medication, like Viagra. But healthy food and (some) vitamins and supplements can improve your overall health and blood flow. And anything that improves blood flow can treat some of the causes of erectile dysfunction (as well as making you healthier).
