Diabetes is known to sabotage two body parts that provide essential components of an erection: nerves and blood vessels. Studies suggest that diabetic nerve damage (neuropathy) is the most important risk factor for ED in people with diabetes. If pelvic nerves that trigger penis muscles to relax are impaired, there may be a break in the chain between brain and penis, disrupting erection. Some researchers suspect that an inadequate supply of oxygen to the nerves causes this damage.

Due to their vasorelaxing effect, administration of PDE-5 inhibitors in hypertensive individuals was initially confronted with great suspicion. A wealth of clinical data however has proven that PDE-5 inhibitors are associated with few side effects and provoke a small and insignificant reduction in blood pressure with minimal heart rate alterations in both normotensive and hypertensive patients as well. As a matter of fact, they can be safely and effectively administered to hypertensive individuals even when they are already taking multiple antihypertensive agents[51-56]. The sole exception to the rule is co-administration with organic nitrates, which is an absolute contraindication due to profound and possibly hazardous hypotension effect[57,58]. Moreover, precaution should be taken when PDE-5 inhibitors are combined with a-blockers where, due to possible orthostatic hypotension effect, lower starting doses should be implemented in the therapeutic regime[59-62].
Low testosterone represents another link between erectile dysfunction and heart disease. A man’s testosterone levels gradually diminish beginning at age 30. By the time he reaches his 70s, testosterone levels may have dropped to a tenth of youthful levels. Diminishing testosterone levels contribute to loss of muscle, increased body fat, and reduced libido. Fatigue is common, as is depression. Low testosterone levels can also result in reduced concentration, irritability, passivity, loss of interest in activities, and even hypochondria.
Low intracavernosal nitric oxide synthase levels are found in people with diabetes, smokers, and men with testosterone deficiency. Interference with oxygen delivery or nitric oxide synthesis can prevent intracavernosal blood pressure from rising to a level sufficient to impede emissary vein outflow, leading to an inability to acquire or sustain rigid erection. Examples include decreased blood flow and inadequate intracavernosal oxygen levels when atherosclerosis involves the hypogastric artery or other feeder vessels and conditions, such as diabetes, that are associated with suboptimal nitric oxide synthase activity.

There are many alternative treatments that may be used to treat erectile dysfunction, although their effectiveness hasn't been proven. Men may benefit from acupuncture to reduce stress and help treat erectile dysfunction. Some people claim that herbal supplements such as Korean red ginseng, ginkgo, and yohimbine may be helpful for treating erectile dysfunction. Other helpful supplements for treating erectile dysfunction may include DHEA (a hormone in testosterone) and L-arginine. However, it's important to remember that these and other supplements may actually contain harmful substances, so talk with your doctor before taking supplements for treating erectile dysfunction.

Men can judge themselves pretty harshly when it comes to their performance in between the sheets. The unsettling fear of not being able to rise to the occasion becomes a reccurring nightmare for men that is often equated with failure, loss of dignity, and masculinity. If you suffer from erectile dysfunction (ED), don’t be so hard on yourself, since impotence can almost always be improved with treatment, without having to rely on Viagra or other medications. Whether you suffer from ED, or hope to prevent the condition, here are six tips to overcome impotence without the side effects of the little blue pill.

Clinical practice in TCM has been an exemplary case of customized treatment with holism epitomizes the essence of TCM. TCM encompasses these aspects, taking a holistic approach to patient’s problem and these methods combine body, mind and spirit, and healings are achieved via the concept of energy rather than matter, as in modern medicine. Compared to the complexity of modern science, which is the basis of Western medicine, this concept is easily understood and comprehended, and is readily accepted because of its holistic approach.

When antihypertensive medication comes to the fore, certain issues need to be carefully addressed. This is due to the fact that medically induced erectile dysfunction is one of the major reasons for non-adherence and treatment discontinuation, a reality that could have deleterious consequences on patient’s cardiovascular profile and health quality in the long term[38,39].
Jelqing is penile massage technique of ancient Arabic origin (52). Men who practise jelqing will stretch their penises while in a semi-erected state and repeatedly milk their penises from base to glans, with their thumb and index finger touching to form an “OK” hand sign around their penile shaft. This massage can be done daily with the aim to achieve greater penile length and harder erections. Unwanted side effects of bruising, pain and fibrosis had been reported. No studies have been done to evaluate the efficacy of jelqing objectively.
Diabetes occurs when you have too much sugar circulating in your bloodstream. There are two main types of diabetes: type 1 diabetes, which affects less than 10 percent of those who have diabetes, and type 2 diabetes, which accounts for over 90 percent of diabetes cases. Type 2 diabetes often develops as a result of being overweight or inactive. Approximately 30 million Americans have diabetes, and about half of them are men.

Experimental in vivo studies have implicated central and peripheral neuropathy, impaired neurotransmission, and endothelial dysfunction in the pathogenesis of diabetic ED.26,27 Copulatory behavior and penile reflexes are uniformly impaired 4–12 months after the onset of diabetes in the BB rat.26,27 McVary et al.26 found that peripheral neuropathy accounts for only part of the dysfunctional findings, and that spinal sexual reflexes were also severely impaired.
Hypertension can affect endothelial function in many ways. It can reduce endothelium-dependent vasodilatation by increasing the vasoconstrictor tone as a result of increased peripheral sympathetic activity.41–43 Another mechanism is hypertension-induced increase in cyclooxygenase activity that leads to an increase in reactive oxygen species; these in turn damage endothelial cells and disrupt their function.44–46 In some cases, endothelial NO synthase (eNOS) gene variations may relate to hypertension-associated endothelial dysfunction.6

Three longitudinal studies have estimated incidence rates of ED in men with diabetes. Unfortunately, none of these studies specifically examined men with type 2 disease. In a cohort of 278 diabetic men with type 1 or type 2 diabetes potent at study entry, the proportion of patients reporting ED at 5-year follow-up was 28%.7 A follow-up analysis of the Massachusetts Male Aging Study, a community-based cohort of men between 40 and 70 years of age, found that the incidence of ED in the diabetic men was 51/1,000 population-years.8 This figure was similar to the 68/1,000 person-years crude incidence rate of ED reported in a study of 1,010 men with diabetes.5 However, new studies need to be carried out in well-characterized populations of men with diabetes in order to better determine the incidence of ED and potential effects of interventions to reduce complications.
Evaluation of functional capacity is the mainstay for the management of patients with ED.30 However, it should be kept in mind that in men with heart failure sexual activity may affect the heart differently from physical activity of similar METS due to differences in psychological anticipation and sympathetic activation.30,49 Cardiac echocardiography may offer valuable information for left ventricular performance and valvular function. For risk categories of heart failure patients and their management, please refer to Table 3 and Figure 5.
Recent revised labeling for sildenafil states that there is a lack of controlled data for its use in patients with resting hypotension (<90/50 mm Hg) or hypertension (>170/110 mm Hg); a history of myocardial infarction, cerebrovascular accident, or life-threatening arrhythmia within the past 6 months; coronary artery disease or cardiac failure causing unstable angina; or retinitis pigmentosa and possible genetic disorders of retinal PDEs.10x10Kloner, RA and Zusman, RM.

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.
Although DM patients often correctly assume that their ED is of organic origin, a psychogenic component should be considered, especially in the younger patient. If this is the case, the patient may benefit from psychosocial therapy that includes anxiety reduction and desensitization, cognitivebehavioral intervention, sexual stimulation techniques, and interpersonal assertiveness with couples communication training.6 Not all healthcare providers offer these options. Freudian-based psychotherapy for EDDM has not been proved to be efficacious.
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.
