Testosterone therapy in hypogonadism modulates metabolic components associated with CV risk. The majority of prospective clinical studies indicates that treatment achieving testosterone levels within physiological limits has beneficial or neutral effects on a lipid profile other than HDL-C, beneficial or neutral effects on inflammatory mediators, and generally beneficial effects on glycaemic state.25 The lean body mass is typically increased in hypogonadal subjects, and visceral adiposity is decreased in several studies and unchanged in the remainder. Such metabolic effects have raised interest on the potential impact on cardiovascular health. Regarding symptoms in patients with pre-existing cardiovascular conditions (angina or heart failure) TTh has been either neutral or beneficial.25 Regarding CVD risk, available clinical trial data indicate that the use of testosterone in middle-aged to elderly men does not increase cardiovascular risk25 with the exception of one study in very frail (substantial limitation of mobility and a high rate of comorbidities) elderly subjects that used an off-label high, and rapid escalation, dosing regimen.46 Prospective data from large, well-designed, long-term trials of TTh are warranted.
There are blood pressure medications that do not cause erectile dysfunction (ED). Some older blood pressure medications, especially beta blockers and thiazide diuretics, are the most likely to cause ED as a side effect. Better options include calcium channel blockers, which lower high blood pressure through a different mechanism. Don't just go off your medications, though; high blood pressure itself is a common cause of ED, so lowering your blood pressure is an important part of your ED treatment plan. And if you stop taking your blood pressure medications 'cold turkey', your blood pressure could actually sky rocket, putting you at risk for a heart attack or a stroke. Work with your doctor on ways to lower your blood pressure without lowering your sex drive.
The common associations between cardiovascular disease and ED have led some researchers to explore whether onset of ED can be an effective predictor of the presence of cardiovascular disease. A study of 40 patients with cardiac disease found an association between sexual dysfunction and the presence of cardiovascular disease, as well as a correlation between the severity of ED and the number of coronary arteries with extensive atherosclerosis.16x16Greenstein, A, Chen, J, Miller, H, Matzkin, H, Villa, Y, and Braf, Z. Does severity of ischemic coronary disease correlate with erectile function?. Int J Impot Res. 1997; 9: 123–126
Patients who use this therapy should be trained under the guidance of a urologist, and sterile technique must be used. The drugs must be injected into the shaft of the penis and into one of the penile erectile bodies (corpus cavernosum) 10–15 min before intercourse. Most patients do not complain of pain upon injection. Sexual stimulation is not required, and resulting erections may last for hours. Side effects include penile pain and priapism. The cost is about $12–20 per injection.
ED is a common complication of diabetes that affects patients' quality of life. While the etiology of this complication may be multifactorial in nature, it is clear that it usually has a strong organic component. Because men with diabetes value their erectile function highly, it is important that providers encourage them to maintain good glycemic, blood pressure, and lipid control to minimize their risk of developing this complication.
ED is easily and successfully treated! If your sex drive is unaffected, but you experience problems achieving or sustaining erection for a period of four to five weeks, you may have ED. Talk to your doctor immediately. Don’t delay—erectile dysfunction doesn’t “just go away!” Additionally, ED could be a sign of a serious, even life-threatening complication, such as congestive heart failure or kidney disease. Ignoring your ED because it’s embarrassing could jeopardize your health.
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."
The obvious risks are the same that accompany any surgery: infection, pain, bleeding, and scarring. If for some reason the prosthesis or parts become damaged or dislocated, surgical removal may be necessary. With a general success rate of about 90 percent, any of the devices will restore erections, but they will not affect sexual desire, ejaculation, or orgasm.
Even if you do not take blood pressure drugs, you should get your blood pressure checked as high BP also can be a sign of ED. In fact, men with ED are about 38% more likely to have high blood pressure than those without ED, according to a study that examined the medical records of more than 1.9 million men. That is not too surprising, since ED often occurs in men who smoke or are overweight—both of which are common risk factors for high blood pressure.
Severe testosterone deficiency, known as “hypogonadism,” is present in approximately 2–35% of men with erectile dysfunction.19 However, lesser degrees of deficiency are common, perhaps present in the majority, depending on the definition of “low” applied, the method of measurement, and the parameter being used to define testosterone (total, free, or bioavailable) deficiency.19,20 Most authorities agree that a total testosterone level below 300 ng/dL is clearly low, and that 300–400 ng/dL is low to low-to-normal. Most studies using testosterone replacement for erectile dysfunction have attempted to achieve blood levels of 450–850 ng/dL.

Sexual dysfunction is a common, underappreciated complication of diabetes. Male sexual dysfunction among diabetic patients can include disorders of libido, ejaculatory problems, and erectile dysfunction (ED). All three forms of male dysfunction can cause significant bother for diabetic patients and can affect their quality of life. Despite this, health care providers often do not specifically ask their male diabetic patients about sexual function. This results in considerable underdiagnosis because patients are often reluctant or embarrassed to initiate discussion of these issues themselves. By not recognizing sexual dysfunction as a common organic sequel-lae of diabetes that should be addressed and treated, providers are missing an important opportunity to improve their patients' daily existence and quality of life.

In years past, before nitric oxide and its role in the erectile response was appreciated, testosterone was used to treat sexual dysfunction in men. It proved a partial success as a standalone therapy, resulting in improved erectile potency in 40–60% of men with low-to-normal testosterone levels. The likelihood of success increased, however, if starting testosterone levels were low (usually defined as below 300 ng/dL), in which case improved erections were experienced by as many as 65% of men, compared with 16.7% receiving placebo; topical testosterone preparations were also noted to be superior to oral replacement or injections.21 These findings were confirmed by another study that showed testosterone produced modest improvements in erectile function and libido in men with low-to-normal testosterone levels.22

A sexually competent male must have a series of events occur and multiple mechanisms intact for normal erectile function. He must 1) have desire for his sexual partner (libido), 2) be able to divert blood from the iliac artery into the corpora cavernosae to achieve penile tumescence and rigidity (erection) adequate for penetration, 3) discharge sperm and prostatic/seminal fluid through his urethra (ejaculation), and 4) experience a sense of pleasure (orgasm). A man is considered to have ED if he cannot achieve or sustain an erection of sufficient rigidity for sexual intercourse. Most men, at one time or another during their life, experience periodic or isolated sexual failures. However, the term “impotent” is reserved for those men who experience erectile failure during attempted intercourse more than 75% of the time.


There’s some evidence that bark from the yohimbe tree can help with ED. The bark contains a substance called yohimbine. It’s been traditionally used in Africa as an aphrodisiac. Today, a pharmaceutical form of yohimbine (called yohimbine hydrochloride) is being studied to treat erectile dysfunction in men. However, it can cause severe side effects, including high blood pressure, tremors, and anxiety.
With atherosclerosis, the blood vessels are not able to dilate properly, which is called endothelial dysfunction (see the Figure). Cholesterol builds up in the blood vessel walls and forms plaques, which make the vessels narrow and slow down blood flow. When a plaque becomes very advanced, it can completely stop blood from passing through, which is what happens in a heart attack. Atherosclerosis affects not only the blood vessels supplying the heart (coronary arteries), but also blood vessels throughout the entire body. Atherosclerosis causes angina (chest pain that is often exertional), heart attacks, strokes, claudication (pain in the legs with walking), and ED. Atherosclerosis affects different people in different places, but it often affects the penis first, then the heart and brain, and the legs last. Because the first stage of atherosclerosis, endothelial dysfunction, usually affects the penis first, ED can be a warning sign that a heart attack or a stroke may follow, often in the next 3 to 5 years. This warning sign can be a good thing if it alerts you and your doctor that you have atherosclerosis, because then you can take steps to treat the atherosclerosis and prevent a heart attack or stroke.
When dealing with certain medical conditions, it is important to focus treatment toward the root of the problem. If you were to properly manage your high blood pressure without the use of any confounding medications and instead employ a lifestyle change, both ailments would likely disappear. While this would be the ideal case, it isn’t the reality for most patients. Medications are great for controlling high blood pressure, but it’s important to speak with your doctor about any concerns before taking them.
Testosterone cypionate and testosterone enanthate injections are used for replacement therapy in patients with low testosterone. Other formulations, such as gels and patches, are recommended in older patients with chronic conditions.57 Serum prostate specific antigen should be measured before starting testosterone replacement, then 3–6 months after starting the treatment, followed by annual measurement.74
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.

Research is mixed on the effectiveness of acupuncture as an erectile dysfunction cure, but one study published in November 2013 in the Journal of Alternative and Complementary Medicine found that acupuncture can be beneficial for men experiencing erectile dysfunction as a side effect of antidepressants, including selective serotonin reuptake inhibitors (SSRIs) and serotonin noradrenaline reuptake inhibitors (SNRIs).

This category of treatments includes external vacuum therapies: devices that go around the penis and produce erections by increasing the flow of blood in, while constricting the flow out. Such devices imitate a natural erection, and do not interfere with orgasm. External vacuum therapy mechanisms are approximately 95 percent successful in causing and sustaining an erection. All are portable, and costs range between $200-$500, covered under most insurance plans and Medicare Part B.
Artery size also explains the onset of ED before occurrence of CAD. Coronary arteries are 3–4 mm in diameter, while the penile artery is 1–2 mm in diameter.17 Endothelial dysfunction and plaque burden in the small arteries may cause symptoms of ED before they affect blood flow in large arteries. Also, an asymptomatic lipid-rich plaque in the coronary arteries carries the risk of rupture that leads to acute coronary syndrome or death, so ED may be predictive of these serious events without warning cardiac symptoms.17

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.
The natural history of ED in people with diabetes is normally gradual and does not occur overnight. Both vascular and neurological mechanisms are most commonly involved in people with diabetes. Atherosclerosis in the penile and pudendal arteries limits the blood flow into the corpus cavernosum. Because of the loss of compliance in the cavernous trabeculae, the venous flow is also lost. This loss of flow results in the inability of the corpora cavernosae to expand and compress the outflow vessels.
For those patients who cannot take erectile dysfunction medications, the authors counsel that an exercise training regimen may be an appropriate substitute therapy to enhance sexual function and quality of life. The authors stress that clinicians should focus on the sexual activity history of chronic heart failure patients and not ignore it, since addressing this element can substantially improve their quality of life.

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.

Gene therapy has the potential to become a future management option for patients with CAD and ED. Animal studies have been conducted to evaluate the effects of gene therapy. A rat model was studied by Bivalacqua et al. to evaluate the effect of the combination of eNOS gene therapy and sildenafil. This research suggested that erectile response was greater in male rats with diabetes treated with combination eNOS gene therapy and sildenafil, compared with male rats with diabetes treated with eNOS gene therapy or sildenafil alone.76–78
Crucial to the understanding of the relationship between ED and CVD and the management of ED patients within the context of the (potential) CVD were the consecutive Princeton Consensus Recommendations (I: 2000, II: 2005, and III: 2012). The reader is strongly encouraged to refer to the most recent, third (2012) Princeton Consensus.30 Key notions in the assessment and management of the patient with organic ED are that (i) he should be considered at increased CVD risk until recommended checks suggest otherwise, and (ii) ED identifies increased CVD risk in the presence or absence of CVD symptoms or history.
No matter what erectile dysfunction treatment or treatments (whether herbal remedies or not) a man ultimately decides upon, experts say it's important to eat healthily and to avoid smoking and heavy drinking. Moreover, adequate exercise, stress reduction, and sleep can improve erectile dysfunction in many. In addition, says Lamm, "A loving, receptive, and responsive partner is a home run. After all, this is still a couple's issue."

For over 25 years, Dr. Fuhrman has shown that it is possible to achieve sustainable weight loss and reverse heart disease, diabetes and many other illnesses using smart nutrition. In his medical practice, and through his books and PBS television specials, he continues to bring this life-saving message to hundreds of thousands of people around the world.

When it comes to combating heart disease, most information sources promote drugs and surgery as the only viable options, with lip service to dietary advice that simply does not work. As a result, the demand for high-tech, expensive, but largely ineffective medical care is soaring, causing medical costs and insurance rates to skyrocket. This chase for "cures" is both financially devastating and futile. Morbidity and premature mortality from heart disease continue to rise, with no sign of abating.
Penile prosthesis is a viable option for men who cannot use sildenafil and who find the injections or vacuum erection therapy distasteful. A non-adjustable semi-rigid prosthesis is easy to insert and has no postoperative mechanical problems. The inflatable prosthesis has a pump that is put in the testicular sac for on-demand inflation and deflation. Future versions will have a remote control device similar to a garage-door opener.
Co-authors Stacy Mandras, M.D., Patricia Uber, Pharm. D., and Mandeep Mehra, M.D., conducted systematic independent literature searches using the MEDLINE database and examined a broad range of medical research that focused on chronic heart failure, sexual activity and sexual dysfunction. This literature included data from patient surveys and clinical trials.
Erectile dysfunction (ED) is common in cardiac patients and shares the same risk factors--smoking, hypertension, hyperlipidaemia and diabetes mellitus. Sexual activity is not unduly stressful to the heart and, providing patients are properly assessed using established guidelines, sexual intercourse can be enjoyed without increased risk. The treatment of ED in patients with cardiovascular disease has been transformed by the introduction of the oral phosphodiesterase type 5 inhibitors, the first of which was sildenafil. Success in restoring erectile function is possible in up to 80% of patients (depending on the aetiology) with minimal adverse effects. A synergistic hypotensive effect with nitrates, and almost certainly nicorandil, is the only major contraindication. ED in asymptomatic patients may be a marker of silent vascular disease or increased vascular risk factors and should alert the physician to the need for cardiac risk screening. ED is common in patients with cardiovascular disease and should be routinely enquired about. ED is a distressing condition for the man and his partner, and severely impairs quality of life. Patients with cardiovascular disease and patients with diabetes represent the largest group of patients with ED, the majority of whom benefit from the drug therapies currently available. Addressing ED in patients with cardiovascular disease can lead to a substantial improvement in quality of life and success is not difficult to achieve.

Alprostadil self-injection. With this method, you use a fine needle to inject alprostadil (Caverject Impulse, Edex) into the base or side of your penis. In some cases, medications generally used for other conditions are used for penile injections on their own or in combination. Examples include papaverine, alprostadil and phentolamine. Often these combination medications are known as bimix (if two medications are included) or trimix (if three are included).
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).
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.
Erectile dysfunction and heart disease are very serious medical conditions that requires prompt treatment. In addition to being a symptom of heart disease; ED is linked to many other physical and psychological problems. Men with ED can be withdrawn from their partner and even avoid romantic relationships. It may be difficult for men with erectile dysfunction to reproduce and can lead to low self-esteem, depression and poor work performance.  Frequent medical check ups for patients with erectile dysfunction and high blood pressure is recommended.

Treatment of ED which was previously confined to invasive procedures, cavernosal injections or to rather ineffective oral medications was revolutionized in 1999 with the introduction of the orally administered PDE5 inhibitor sildenafil. Phosphodiesterase type 5 inhibitors are the first-line therapy for ED of organic aetiology unless there is a specific contraindication to their use. This class of agents is widely used because of its effectiveness and safety.38 Interactions with cardiovascular drugs have been minimal with the exception of nitrates and other nitric oxide (NO) donors (such as nicorandil), where co-administration may result in severe vasodilation and hypotension. However, nitrates are often overused in clinical practice; therefore, the option of their discontinuation should be considered. A strong body of clinical data shows that all three agents (sildenafil, tadalafil, and vardenafil) do not increase the risk of non-fatal myocardial infarction, stroke, or cardiovascular deaths. These drugs do not exacerbate ischaemia or worsen exercise tolerance in patients with known CAD who achieve levels of exercise comparable or greater than that achieved during sexual intercourse.38,39 Phosphodiesterase type 5 is expressed throughout the human body, including the pulmonary and systemic vasculature and hypertrophied myocardium. While currently their only additional indication, beyond ED, is idiopathic pulmonary hypertension (for sildenafil and tadalafil), they show potential to be of benefit in several other conditions, such as CAD and systolic heart failure.39 Mechanisms of benefit of PDE5 inhibitors include pulmonary and systemic vasodilation, increased myocardial contractility, reduced large artery stiffness and wave reflections, improved endothelial function, and reduced apoptosis, fibrosis and hypertrophy through mechanisms involving NO, cyclic guanosine monophosphate, protein kinase G and Rho kinase.39 A very important issue is whether treatment of ED per se (and not of its risk factors and comorbidities) will have an impact on cardiovascular risk. While this applies to all therapeutic modalities of ED, it is particularly pertinent for PDE5 inhibitors, since they represent the mainstay of ED therapy. Data are limited to date. Gazzaruso et al.21 showed a trend of PDE5 inhibitors to reduce cardiovascular morbidity and mortality in diabetic patients with silent CAD and ED, while Frantzen et al.40 showed that 2 years after the introduction of sildenafil, the relative risk of the incidence of CVD among men with ED compared with healthy men significantly decreased from 1.7 to 1.1.

In a study by Segal et al. (11), 4 out of 5 healthy individuals were able to achieve tumescence beyond 60% maximum rigidity when subjected to PVS using the Viberect® alone, with no other external visual sexual stimulation. In a randomized controlled study by Fode et al. (12) involving 68 men who underwent nerve-sparing radical prostatectomy, 30 men who received PVS to the frenulum daily for 6 weeks, using the Ferticare® vibrator, showed a trend towards better erections. After 1 year, 53% in the PVS group had an IIEF score ≥18 compared with 32% in the control group, although no statistical achievement was achieved. The role of PVS in penile rehabilitation is based on the postulation that PVS provides early activation of the parasympathetic erectile spinal centres at S2–S4 level, which result in early recovery of the neuropraxic cavernosal nerves.

One study the authors reviewed measured these changes in middle-aged men with and without coronary artery disease. This study found that the peak heart rate during intercourse was lower than heart rates measured during the patients' normal daily activities. The study participants' peak oxygen consumption levels during intercourse were moderate -- comparable to their oxygen consumption levels during moderate activities such as walking on level ground at 3 to 4 miles per hour, climbing stairs slowly or doing general housework such as vacuuming.
The art of acupuncture has become the new treatment for everything from back pain, depression, and even ED. Impotence could be more of a state of mind, and acupuncture may help. Through this alternative therapy, fine needles are placed in various parts of the body to relieve pain or stress. Although there are many mixed studies for acupuncture and ED, many tend to confirm positive results. A 1999 study found acupuncture improved the quality of erection and even restored sexual activity in 39 percent of participants.
A number of drugs are known to cause ED in patients with DM (Table 1). For example, many EDDM patients are on antihypertensive medications. Replacement of thiazides or beta-blockers with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers may be sufficient to regain erectile ability.5 Furthermore, discontinuation of selective serotonin reuptake inhibitors, if these drugs are not essential for patient well-being, may be therapeutic. Careful monitoring following drug discontinuation will help to determine if ED is due to the medication or other underlying disorders. The benefits of continued drug therapy with these drugs should always be weighed against the likelihood of causing ED and impacting on the patient's QOL.
There are a number of reasons a man may not achieve the desired result from an oral erectile dysfunction drug. In some cases, a man may experience drug side effects severe enough to outweigh any potential benefit of taking the drug. Possible side effects of these drugs include headache, facial flushing, nasal congestion, and transient abnormal vision. (In October 2007, the FDA added a warning about sudden hearing loss to the package labels of oral erectile dysfunction drugs. While it’s not absolutely clear that the drugs can cause sudden hearing loss, a number of cases have been reported in men within hours or days of taking one of the drugs.)
