The EDDM patient has a variety of firstline options. The risk factors for vascular disease are the risk factors for ED. First-line therapy begins with attempts to minimize or eliminate these factors. These include smoking cessation, regular exercise, tighter glycemic control by attention to dietary restrictions, addition of statin drugs to correct dyslipidemia, and moderation of alcohol ingestion. Although there is very limited evidence that these modifications will dramatically reverse ED, they certainly will sponsor improved general health.4
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.

A study conducted by Prince Henry’s Institute in Melbourne Australia published in the Medical Journal of Australia found that men over 20 years of age with erectile dysfunction (ED) have twice the risk of cardiovascular incidents than those of men with normal sexual health. It was also found out that 2% of men aged 55 and older experienced major stroke and cardiac arrest after the initial episode of ED, within a year; 11% experienced something within five years. Experts from Prince Henry’s Institute warned men with these failures to seek advice on erectile dysfunction and high blood pressure. This may indicate a missing vital warning sign of impending heart disease. Why is this happening? Do men with ED predispose themselves to have cardiovascular diseases and strokes or just the other way around?
Qigong is a form of breathing exercises commonly practised in Asia to maintain health (53). In a cross-sectional population-based comparison study in Taiwan, individuals practising Qigong demonstrate higher SF-36 scores in the domains of physical functioning, role limitations due to physical problems, bodily pain, general health and vitality (54). Techniques to concentrate the energy or qi in the pelvis or genitals are regularly practised, but the effects of Qigong on ED have not been studied.
The cardiovascular adverse effects of sildenafil use have been studied extensively. Phosphodiesterase type 5, although located primarily in the genitalia, also can be found throughout the systemic vasculature, although other PDEs predominate there10x10Kloner, RA and Zusman, RM.

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
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.
Like the case of untreated hypertensive patients, evaluation of sexual dysfunction in hypertensive patients under antihypertensive regime, should primarily exclude other concomitant diseases and pharmaceutical agents. Consecutively, a competent physician with advanced communicational skills should try to “discover” medically induced erectile dysfunction since a vast majority of patients being under complex antihypertensive regimes usually attribute the undesirable effect to normal aging thus not relating it to their current medication. Moreover, even physicians seldom report the cases of sexual dysfunction associated with certain medications. When medically induced sexual dysfunction is finally disclosed and a shift in medication is deemed necessary, b-blockers along with diuretics should generally be the first categories to be changed, unless they are deemed absolutely indicated for the individual patient. Ideally, an ARB could constitute the mainstay of therapy in these cases. If sexual dysfunction still persists, then more effective remedies should be elected paving the way for the introduction of phosphodiesterase-5 inhibitors (PDE-5).
Side effects of sildenafil are similar to those from taking niacin or any vasodilator, namely, headaches, lightheadedness, dizziness, and flushing. Some individuals experience a bluish tinge of their cornea, which makes them feel as if they are wearing light blue–tinted sunglasses. This effect can last for several hours. Syncope and myocardial infarction, the most serious side effects, are seen in men who are also taking nitrates for coronary heart disease. Sildenafil also has adverse effects in people with hypertrophic cardiomyopathy because a decrease in preload and after load in the cardiac output can increase the outflow obstruction, culminating in an unstable hemodynamic state.

If you can't take one of these oral medications, your physician may have you try Caverject (alprostadil for injection), a hormone that you inject into your penis using a fine needle, or Muse (alprostadil urogenital), a tiny suppository that you insert into the tip of the penis. Both of these will bring on an erection within five to 15 minutes without sexual stimulation.
To date, there are no studies directly comparing the effectiveness of these three agents among diabetic men with ED, so it is impossible to state that one agent is superior to another in terms of effectiveness in diabetic patients. However, there are an number of studies that compare the individual agents to placebo in diabetic men with ED. For example, Boulton et al.41 completed a 12-week double-blind, placebo-controlled randomized clinical trial of the effectiveness of sildenafil in 219 men with ED and type 2 diabetes. They found that sildenafil resulted in a significant improvement in the ability to both achieve and maintain an erection adequate for sexual intercourse in men with type 2 diabetes. In a similar study, Rendell et al.42 randomized 268 diabetic men with ED to receive either sildenafil in a dose-escalation manner or placebo. At the conclusion of the 12-week study, 56% of the patients in the sildenafil arm reported improved erections, compared to 10% in the placebo arm (P < 0.001). Additionally, 61% of patients in the diabetic arm reported at least one successful attempt at sexual intercourse in the final month of the study, compared to 22% in the control arm (P < 0.001). Similar randomized studies have documented the effectiveness of both tadalafil43 and vardenafil44 in the treatment of diabetes-related ED.
Finally, prevalence rates will be affected by whether the study population is accrued from a single hospital/clinic setting or from a more general population of men with diabetes. For example, Siu et al.4 studied 500 Chinese diabetic men (of which 97% had type 2 disease) seen at a single medical clinic in Hong Kong during 1999 and found the overall prevalence of ED to be 63.6%. Contrast this to Fedele et al.,5 who studied 9,756 diabetic men accrued from 178 diabetes centers in Italy. Among the 8,373 men with type 2 diabetes, only 37% reported ED, considerably less than in the Chinese study.

Now that we better appreciate the complex sequence of events necessary for erections to occur, it’s no surprise that testosterone alone yields less than perfect results. Erectile dysfunction represents more than just low testosterone, which is just one facet of the spectrum of dysfunctional phenomena that cause sexual dysfunction. Nonetheless, when testosterone is combined with popular drugs like Viagra®, success is enhanced to an even greater degree—orgasmic function improves, along with erectile capacity and libido.20 Testosterone also activates penile nitric oxide; ultrasound studies have demonstrated a 27% increase in arterial blood flow into the penis with testosterone supplementation.23

Treatments might be slightly different for different people, depending on their risk factors, but in general all treatment plans have similar elements: diet, exercise, and medications, if necessary (see the Table). Diet and exercise are the cornerstones of the treatment of atherosclerosis. Every diet should include low salt (especially for high blood pressure), low fat and cholesterol (especially for high cholesterol), and limited total calories (especially for patients who are overweight). People with diabetes mellitus should limit their intake of sugars and carbohydrates. Exercise helps to limit atherosclerosis. The more exercise, the better, but every little bit helps. The general recommendation is 30 minutes a day 5 days a week. Check with your doctor to be sure that an exercise program is safe for you. Cigarettes cause a variety of health problems, including atherosclerosis, so cigarette smoking should be stopped. If diet and exercise are not enough to control your atherosclerotic risk factors, then your doctor will prescribe medications. Heart attacks are prevented by controlling atherosclerotic risk factors, which means diet, exercise, and medications if necessary.
Before a man concludes that oral drugs don’t work for him, he should have his testosterone levels checked to rule out hormone deficiency as the cause of (or as a contributor to) his sexual dysfunction. Other symptoms of low testosterone include a low sex drive and infertility. Checking testosterone levels requires a blood test. If a man’s levels of testosterone are decreased or at the lower end of normal, his doctor may prescribe supplemental testosterone therapy, either as testosterone injections or testosterone gel, which is applied daily to the skin. In some cases, testosterone therapy alone can resolve sexual dysfunction, or it can be combined with the use of oral erectile dysfunction drugs.
