A collection of risk factors that strongly predict heart disease—termed the metabolic syndrome—is also associated with erectile dysfunction. An increasingly prevalent condition, this syndrome includes low HDL, increased triglycerides, high blood sugar, and heightened inflammation and causes a three-fold or greater risk of heart attack, stroke, and diabetes. It is largely attributable to excess weight, poor diet, and inactivity and afflicts at least 47 million Americans, signaling that an epidemic of erectile dysfunction is sure to follow. Indeed, a survey of 2,400 men participating in a health screening revealed that metabolic syndrome increases the likelihood of erectile dysfunction by 48%.10
Impotence, or erectile dysfunction (ED), is the inability for a man to sustain an erection long enough for normal, satisfying sexual intercourse.  To understand the underlying causes of impotence, it helps to know the basics about how an erection develops, along with potential problems that get in the way. Erections begin in the brain with a thought related to sexual desire. Then a chemical message travels from the brain to the penis. Blood flow to the penis increases as blood vessels leading to the reproductive system relax and allow for increased circulation.

Ginseng, specifically “red ginseng,” is known as the “herbal Viagra” that helps puts to rest men’s bedroom woes. Red ginseng is when the root has been steamed and then dried. The ginseng root is the part of the plant that is mostly used as a natural remedy when in its supplement form. However, the plant must be grown for a minimum of five years before it can be used. In a 2008 review, seven studies on red ginseng and ED, ranging in dosages from 600 to 1,000 milligrams three times a day, were found to provide evidence for the effectiveness of the herb in ED treatment.
For centuries, men have tried all sorts of natural remedies for erectile dysfunction (ED) -- the repeated inability to get or maintain an erection firm enough for sexual intercourse. But do they really work? It is simply not scientifically known at this point. Furthermore, you take these remedies at your own risk, because their safety profiles have not been established. What follows are commentaries by experts and reviews in the field of alternative treatments that are available over the counter for erectile dysfunction and impotence.

Sexual dysfunction has been evaluated in ancient literature of TCM in terms of subjective sensation and the actual sexual performance (3). In TCM, methods and matters related to direct sexual activity is described in terms of “ten motions”, “seven impairments” and “eight benefits”, which asserted that the ideal intensity and frequency of sexual activity should be moderate. TCM is all about balance, to achieve better overall regulation of the yin and the yang. The aim of treatment of ED using TCM is not for the end point of a penile erection but rather for a natural and harmonious sex life. TCM aims to achieve regulation in terms of the man’s anxiety, fatigability, changing hormonal levels, insomnia and gastroparesis. Medicine to invigorate qi can enhance physical fitness, and medicine to warm the kidneys can regulate sex hormones, increase libido, invigorate the spleen, regulate the stomach and improve general well-being (3). Medications used to treat a “stagnated liver” provide tranquilization and helps to stabilize the mind, hence improving mental processes and emotional wellness. As a result, the patient’s overall condition and quality of life is improved.
Penile vibratory stimulator is a battery operated device with oscillating discs that can provide excitation of afferent penile nerves at various regulated frequency and amplitudes. PVS has been utilised to activate the ejaculatory reflex for patients with spinal cord injury above T10 seeking to collect retrogradely ejaculated semen in fertility treatment (10). The Viberect is a vibratory stimulation handheld device approved by FDA for treatment of ED. It is clamp-shaped with two oscillating discs facing each other near the tips, and the glans penis is placed between the two oscillating discs to receive concurrent dorsal and ventral stimulation at adjustable frequencies and amplitudes.
The medications used to treat high blood pressure do not take into account the symptoms of erectile dysfunction, as their intention is to lower the blood pressure to a more manageable state, reducing the stress put on blood vessels. High blood pressure and ED are seen as separate entities, with the former taking priority for pharmaceutical treatment. This means that the medications used might do nothing to cure erectile dysfunction and may, in fact, prolong it. Medications that lower blood pressure might actually cause a low blood pressure state in the groin area and the arteries supplying the penis, making it near impossible to achieve an erection. The following are examples of such medications:
However, population-based studies of ED in prostate cancer survivors also document that ED has a negative effect on general health. Penson, et al.36 studied HRQOL in 2,306 prostate cancer survivors 2 years after their diagnosis. They noted that men with ED (defined as erections that were insufficient for sexual intercourse) had significantly worse general HRQOL when compared to prostate cancer survivors who were potent. Importantly, this association remained in a multivariate analysis that controlled for 31 other potential confounding variables. Finally, this association was noted in both the physical and mental domains of general quality of life, indicating that ED has a much broader effect on quality of life than one might expect.
A significant proportion (ranging from ∼60 to 90%) of heart failure patients report ED and marked decrease in sexual interest, with ultimately one-quarter reporting cessation of sexual activity altogether.48 Erectile dysfunction contributes further to the poor quality of life and aggravates depression. Of interest, many heart failure patients place a greater importance on improving the quality of life (including sexual activity) than on improving survival. Sexual function correlates with the symptomatic status (i.e. NYHA functional class and 6-minute walk test).48 In the Evaluation of Role of Sexual Dysfunction in the Saarland (EROSS) Program, left ventricular dysfunction was a risk factor for ED independent of heart failure symptoms. While heart failure and ED share common pre-disposing risk factors, heart failure by itself can cause ED or affect engagement to sexual activity. Neurohumoral activation, medication (thiazides), limited exercise capacity, and depression are responsible.49

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:

When these drugs don't work, there are other options. Medications that dilate blood vessels, such as alprostadil, can be injected or deposited in the penis; they work in more than 80 percent of men with diabetes. Beyond that, penile implants can be an effective surgical solution. Implants are either malleable rods, which can be manually adjusted to the desired position, or inflatable cylinders that fill with fluid when a pump under the skin of the scrotum is pressed.

If you bike a lot and have a very narrow saddle on your bicycle, consider switching to a "no-nose seat" which is wider at the back than a conventional saddle, allowing more of your weight to be distributed to the sitting bones. Make sure the seat is level or angled slightly downward and at a height that allows your knee to be just slightly bent at the bottom of the pedal cycle. Raising the handlebars on your bike so that you're sitting upright may also help.

Finding a satisfying solution to ED can be a life-changing event for many men and their partners. In one study of 200 patients and 120 partners, both men and their partners found the AMS penile implant to be satisfying. 92% of patients and 96% of their partners reported sexual activity to be excellent or satisfactory.10 Talk to your doctor about your ED treatment options.

I have cared for hundreds of men with erectile dysfunction that have reversed their condition with a Nutritarian diet and the judicious use of dietary supplements. I have cared for hundreds of heart patients with angina and advanced heart disease, who have turned their backs on invasive cardiac procedures, recovered from angina and opened up the closed blood vessels in their diseased hearts. Out of thousands of men with advanced heart and erectile problems who have followed my nutritional advice, I have never had a patient suffer a heart attack or cardiac related death.
Deer velvet is a covering found on the growing bone and cartilage of deer’s antlers. In Eastern medicine, deer velvet is sought after for its Chinese medicinal properties which include boosting one’s endurance and improving one’s immunity. People have also used deer velvet as an aphrodisiac or to treat ED. The randomized double-blind placebo-controlled study on deer velvet by Conaglen et al. (31), no benefit but this study was underpowered involving healthy participants with no sexual dysfunction.
Physical and emotional stress — whether over-exercising, under-sleeping or just dealing with everyday stressors like work and a busy schedule — causes an increase in “stress hormones,” including cortisol and adrenaline. Stress can lower desire for sex. This is because stress can contribute to fatigue or preoccupation with other tasks. It can also significantly affect blood flow by increasing inflammation.
A medical history focused on risk factors, such as cigarette smoking, hypertension, alcoholism, drug abuse, trauma, and endocrine problems including hypothyroidism, low testosterone levels, and hyperprolactinemia, is very important. Commonly used drugs that disrupt male sexual function are spironolactone (Aldactone), sympathetic blockers such as clonidine (Catapres), guanethidine (Islemin), methyldopa (Aldomet), thiazide diuretics, most antidepressants, ketoconazole (Nizoral), cimetidine (Tagamet), alcohol, methadone, heroin, and cocaine. Finally, assessment of psychiatric history will help identify emotional issues such as interpersonal conflict, performance anxiety, depression, or anxiety.

After the initiation of TTh patients should be evaluated at 3 and 6 months, and annually thereafter to assess response to treatment and monitor adverse effects. Assessment should include physical examination with particular attention to the prostate. At these intervals testosterone levels should also be monitored, as well as PSA, haematocrit, and HDL.45

De Berardis et al.6 assessed general HRQOL in 1,460 men with type 2 diabetes in Italy. Within the cohort, 615 men reported that they never experienced ED, 346 stated that they occasionally had ED, and 449 stated that they frequently had ED. They then compared general HRQOL among these three groups. In the univariate analysis, they found that degree of ED negatively correlated with general HRQOL scores in all eight domains of the Short Form 36 (SF-36) health survey questionnaire. In the multivariate analysis, ED was not independently associated with physical function, bodily pain, or role limitations due to physical problem scores but was independently associated with general HRQOL outcomes in the domains of general health (P = 0.004), role limitations due to emotional problems (P = 0.001), vitality (P = 0.001), social functioning (P = 0.01), and overall mental health (P = 0.002). Another study examining the effect of ED on quality of life in hemodialysis patients, more than half of whom had diabetes, also noted an independent, negative effect of ED on the emotional domains of general HRQOL.39

Another oral treatment that has been used with very little success is yohimbine (Yocon, Yohimex). This is an alpha 2 adrenergic receptor blocker that increases cholinergic and decreases adrenergic tone. It stimulates the mid-brain and increases libido. Optimal results occur when used in men with psychogenic ED. Side effects include anxiety and insomnia.

According to the Mayo Clinic, oral medications are usually the first-line treatment for ED. Those medications include Sildenafil (Viagra), vardenafil (Levitra, Staxyn), tadalafil (Cialis) and avanafil (Stendra). They operate by helping relax muscles in the penis by strengthening the effects of nitric oxide, a naturally occurring chemical in the body. The drugs increase blood flow to allow patients to get an erection.
Yes, and there’s the rub. High blood pressure, especially if untreated, can lead to erectile dysfunction (ED). So can medications your doctor prescribes to bring down your high blood pressure. Fortunately, not all meds cause ED. Thiazides, diuretics or “water pills,” are common ED culprits. So are beta blockers. These effective heart meds slow your system down, and also affect blood flow where you need it -- in your penis -- at the right time. Alpha blockers, another class of medications that lower high blood pressure, are less likely to cause ED. So talk with your good doc about medication choices and side effects, so you can choose the right med for you.
Men with diabetes tend to develop erectile dysfunction 10 to 15 years earlier than men without diabetes. As men with diabetes age, erectile dysfunction becomes even more common. Above the age of 50, the likelihood of having difficulty with an erection occurs in approximately 50% to 60% of men with diabetes. Above age 70, there is about a 95% likelihood of having some difficulty with erectile dysfunction.
