Despite its limitations in detecting CVD without significant stenosis, EST (with or without imaging) can further define the cardiovascular risk in patients with ED and no overt CAD and may be particularly helpful for identifying silent CAD in patients with diabetes. Chemical stress tests are appropriate for patients who cannot complete an EST or in whom ECG is non-interpretable. In patients with established CVD, an interpretable EST is mandatory in the indeterminate risk category and is at the discretion of the cardiologist in the low risk category (Table 3B), since it determines exercise ability and estimates cardiovascular risk associated with sexual activity.
Erectile dysfunction started to become a household term after scientists discovered a drug to treat it. Nowadays, as anyone who watches TV can attest, there are several different medications for ED. Fifty to 70 percent of men with type 1 or type 2 diabetes respond to a class of drugs—including sildenafil (Viagra), var­denafil hydrochloride (Levitra), and tadalafil (Cialis)—called phosphodiesterase-5 inhibitors.

Prescription drugs called “oral phosphodiesterase-5 (PDE5) inhibitors” are considered the “first-line non-invasive treatment” options for patients with ED. These include the drugs that go by brand names: Sildenafil, Vardenafil or Tadalafil. They work by helping the smooth muscle cells lining the blood vessels that supply the penis with blood to work properly. This allows a man to maintain an erection more easily.

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.

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.

Get your diabetes under control. According to Dr. Nehra, the most important number you need to stay on top of is your A1C, which is a blood test that lets you know how well your blood sugar has been controlled for the past few months. Lifestyle changes can help and so can medications. Diabetes medications do not add to your risk for erectile dysfunction, says Nehra.

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:

If you’re taking medication to treat blood pressure, depression, pain, allergies, inflammation, seizures, or heart conditions, you’re one of the tens of millions of people at risk for medically induced erectile dysfunction. It’s just the nature of drug side effects. Yet erectile dysfunction is one of the least talked about side effects of prescription medication.
Erectile dysfunction is an accurate predictor of heart attacks and strokes in the future. Psychogenic components play a role in erectile dysfunction, but the most common and primary cause in most men is organic vascular insufficiency, meaning not enough blood gets to the penis. Erectile dysfunction usually occurs one to five years before a male manifests overt signs of cardiovascular disease. The first sign may be death.
There are few data specifically relating to the effectiveness of vacuum erection devices (VEDs) in diabetic men with ED. In a single-center study of 44 men with diabetes who choose VED for the treatment of ED in the early 1990s, 75% reported that they were able to achieve erections satisfactory for intercourse with the use of the device.51 However, the manner in which patients were accrued to this study probably biased its findings, resulting in substantially higher effectiveness rates than are normally observed in clinical practice. A recent review of the use of VEDs in the general treatment of ED notes that satisfaction rates with this therapy are much lower, varying between 20 and 50%.52

Inflatable prostheses are complex mechanical devices that imitate the natural process of erection. Parts are inserted surgically into the penis and scrotum, and activated by squeezing. When erection is no longer desired, a valve on the pump is pressed, and the penis becomes flaccid. Self-contained single-unit prostheses are similar to the inflatable types, but more compact. The entire device is implanted into the penis. When erection is desired, the unit is activated by either squeezing or bending, depending on which of the two types of self-contained prostheses is used.


Because ED has several causes, sorting out exactly what is causing your problem may take some time. First, make sure your doctor knows about all the medicines you are using, including over-the-counter or herbal products. Drugs frequently used to treat high blood pressure, anxiety, depression, and peptic ulcers can all cause ED. But don’t stop taking any of your medications without first talking to your doctor.
Diabetes is one of the most common causes of ED. Men who have Diabetes are three times more likely to have Erectile Dysfunction than men who do not have Diabetes. Among men with ED, those with Diabetes are likely to have experienced the problem as much as 10 to 15 years earlier than men without Diabetes. A recent study of a clinic population revealed that 5% of the men with ED also had undiagnosed Diabetes. The risk of ED increases with the number of years you have Diabetes and the severity of your Diabetes. Even though 20% to 75% of men with Diabetes have ED, it can be successfully managed in almost all men.
Quassinoids isolated from Tongkat Ali have been reputed to be anti-tumor, anti-malarial, anti-amoebic and anti-inflammatory. Its leaves are used for washing itches, its fruits for the treatment of dysentery, its bark used as a vermifuge, the taproots used for treatment of hypertension and the root bark for treatment of diarrhea and fever. The roots extracts are used for sexual dysfunction, aging, malaria, cancer, diabetes, anxiety, aches, constipation, exercise recovery, fever, increased energy, increased strength, leukemia, osteoporosis, stress and syphilis. Animal studies done on middle age sex rats showed enhancement of the sexual qualities in terms of hesitation time among middle aged rats (46).

Three FDA-approved oral medications, sildenafil, tadalafil, and vardenafil are available. These drugs are phosphodiesterase type 5 (PDE-5) inhibitors that can prolong levels of cGMP in tissue allowing improved smooth muscle relaxation, thus facilitating an erection. PDE-5 inhibitor drugs are effective in 56-63% of diabetic men with ED. More stringent glycemic control can improve these results. Men with testosterone deficiency may benefit from a combination of oral ED medication and testosterone supplementation.
In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction. 

After analyzing 28 previous studies on the link between ED and heart disease, the researchers found a connection between erectile dysfunction and poor endothelial function. “Blood vessels are unable to fully dilate and allow blood to flow through,” explains Medicalnewstoday.com. “Endothelial dysfunction is an early sign of atherosclerosis, a condition in which plaque builds up in the arteries, raising the risk of heart attack and stroke.” The researchers also determined that there was a thickening of one of the inner two layers of the carotid artery—another heart-disease indicator.

If you have several atherosclerotic risk factors or symptoms of heart disease, your doctor might do additional tests to look for atherosclerosis in the coronary arteries. A stress test involves monitoring the heart with an electrocardiogram or images before and after exercise. An angiogram, or cardiac catheterization, involves entering a blood vessel in the leg or wrist to pass instruments into the heart to directly visualize the coronary arteries. During this procedure, atherosclerosis can be treated by inflating a balloon or placing a metal stent in the coronary blood vessel to keep it open. If you and your doctor begin a treatment plan to prevent atherosclerosis at the first sign of ED, then you may significantly delay or prevent the need for these more invasive procedures.
What comes after an ED diagnosis in diabetic patients? Often, Dr. Eid will instantly refer these men to a cardiologist. “If a patient has diabetes and is newly diagnosed, a significant portion of these men are going to develop coronary artery disease in the next 2-3 years,” he said. “One of the things we do is recommend is that they see a cardiologist and perhaps have a stress test or some sort of evaluation.”
Arterial hypertension is a major risk factor for cardiovascular disease and affects approximately one third of the adult population worldwide. The vascular origin of erectile dysfunction is now widely accepted in the vast majority of cases. Erectile dysfunction is frequently encountered in patients with arterial hypertension and greatly affects their quality of life of hypertensive patients and their sexual partners. Therefore, the management of erectile dysfunction in hypertensive patients is of paramount importance. Unfortunately, erectile dysfunction remains under-reported, under-recognized, and under-treated in hypertensive patients, mainly due to the lack of familiarity with this clinical entity by treating physicians. This review aims to discuss the more frequent problems in the management of hypertensive patients with erectile dysfunction and propose ways to overcome these problems in everyday clinical practice.

When your blood pressure is high for an extended time, it can damage the lining of your arteries and interfere with your blood flow. This appears to affect your ability to get and maintain an erection. A 2012 study published in the journal Current Opinion in Nephrology and Hypertension found that approximately 30 percent of men with hypertension complain of ED.
In TCM, the meridian system is thought to represent a path through which the life energy qi flows and as discussed in earlier section, the “Jing” (kidney) qi plays an important role in penile erection. Acupuncture helps to correct the imbalances to relieve physical symptoms by stimulating various meridian points. The Shensu (BL23), Zusanli (ST36) and Neiguan (PC6) points represents important acupoints for penis stimulation and thus has a positive homeostatic effect on the autonomic nervous system, and potentially modulate NO release (55,56). While some studies have showed up to a third of patients reported improvement in penile erection and sexual activity, systematic review showed insufficient data to conclude that acupuncture is an effective intervention for treating ED (56,57). Therefore, further scientific research is required to investigate whether there are specific benefits of acupuncture for men with ED before acupuncture can be accepted as evidence-based practice.

The bad news: Men with diabetes are three times more likely to report having problems with sex than non-diabetic men. The most common sexual problem is Erectile Dysfunction, or ED, sometimes called impotence. Even worse, because ED is such a private issue, many men feel embarrassed to discuss the problem with their doctor, or even their partner, so the problem is never addressed.
