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.

Conversely, and of significant clinical importance, is how often patients with ED as their first and sole clinical manifestation suffer from subclinical CAD.17 Previous studies reported a rate of inducible ischaemia by exercise stress testing (EST) in 22% (with a wide range of 5–56%) of ED patients reflecting differences in patient population, risk factors and criteria used for ED and CAD diagnosis. Interestingly, those patients further assessed with coronary angiography had obstructive atherosclerosis in >90% of cases.4,18 In a prospective angiographic study, we documented that 19% of ED patients suffer from clinically silent obstructive CAD.18
Since time immemorial, TCM has been adopted by many cultures and is widely practiced in Asian countries despite paucity of level 1 clinical evidence and limited published safety records. TCM is more congruent with Asian values, beliefs and philosophical orientation to health, simple administration, readily available and ease of access or procurement, and general belief that TCM is safer. While Asian males are clearly different from their Western counterparts with respect to biology, culture and beliefs, the practice of TCM appears to be adopted by many Western nations lately. Many men seek TCM to avoid embarrassing visits to physicians and potential side effects of pharmaceutical drugs, or after becoming frustrated with the outcome of modern medicine. Patients are choosing to take more responsibility for their health by exploring a variety of non-pharmaceutical drugs and wellness practices. Furthermore, TCM such as herbal medicine does not address a specific organ system only and is meant to restore and realign the vital energy within the body, which is responsible for ageing, clinical diseases and the deterioration of bodily function; while in Western medicine, each pill is intended for a specific organ/system and that a patient may need a collection of pills to treat multiple comorbidities, rendering modern medicine less attractive to TCM.
Third, men with Diabetes need to control their blood sugar levels. When your blood sugar is not under control, your body does not produce enough Nitric Oxide (NO) and vascular tissues don’t respond as effectively to NO. When enough blood flows into the penis, penile veins close off and block the blood from flowing out. This process results in an erection. If your body does not produce enough NO or if your penile tissues do not respond to NO, the pressure of the blood flowing into your penis is not sufficient to trap the blood, you penis will not get hard.
An equally valuable observation though, is the fact that sexual dysfunction could indeed indicate asymptomatic CV disease. A solid amount of evidence accumulated over the last years has pointed out towards that trend moving, hesitatingly though, sexual dysfunction in the surface of scientific interest. As such, commonly under-reported, under-recognized and under-treated, sexual dysfunction could indeed play its role in cardiovascular risk assessment and stratification.

Finding a potential early sign of heart disease is vital: Every minute in the United States someone dies from a heart disease-related event. Doctors know to watch for risks like obesity and high blood pressure; however, Men’s Health reports 50 percent of men who die from heart disease have never had one of these symptoms. For younger men, treating ED as an indicator of heart health could be a lifesaver.

And yes, this may all seem easier said than done, when it comes to a condition that is more often than not the subject of jokes—or the cause of embarrassment. Talking to your doctor is the first step in dealing with this complication, which can wreak havoc on your quality of life. Keeping diabetes in check and enjoying a healthy lifestyle can make a huge difference in reducing ED risk, but if that isn't enough, there are successful treatments. Sex brings a range of physical and psychological benefits, whether you have diabetes or not. Preventing or reversing ED isn't just about sex—it's a step toward better health and a more satisfying life.
Medications used in the treatment of cardiovascular disease, especially antihypertensive medications, have been implicated frequently in the development of sexual dysfunction. A study of 5485 patients in the Hypertension Detection and Follow-up Program found that, during a 5-year period, 8.3% of male hypertensive patients stopped taking their antihypertensive medications secondary to sexual adverse effects.35x35Curb, JD, Borhani, NO, Blaszkowski, TP, Zimbaldi, N, Fotiu, S, and Williams, W. Long-term surveillance for adverse effects of antihypertensive drugs. JAMA. 1985; 253: 3263–3268
After getting a diagnosis of ED, most patients can begin treatment right away, but treatment may be delayed for some patients until the health of the heart is more fully assessed or improved. The most common treatment for ED is a pill (phosphodiesterase-5 inhibitor; PDE5-I): Viagra (sildenafil), Cialis (tadalafil), or Levitra (vardenafil). Each of these pills improves erections when taken before sexual activity; alternatively, a low dose of Cialis can be taken once a day. These medicines work by allowing the blood vessels that supply blood to the penis to dilate better during sexual stimulation. The PDE5-Is decrease blood pressure a little bit, but they are safe with most other medications and with other blood pressure pills. The PDE5-Is are not safe with nitrate medications like nitroglycerin, Nitrostat, Nitro Paste, Imdur, isosorbide mononitrate, and Isordil. Mixing a PDE5-I with a nitrate medication could result in severely low blood pressure and even death. Inform all medical professionals (including the ambulance or emergency department) about your most recent ED pill ingestion so that nitrates can be avoided. If you have high blood pressure or benign prostatic hypertrophy (enlarged prostate) and take medicines called α-blockers, your doctor may need to start you on the lowest dose of the PDE5-I.
A number of nonprescription products claim to be herbal forms of Viagra. Some of these products contain unknown amounts of ingredients similar to those in prescription medications, which can cause dangerous side effects. Some actually contain the real drug, which should be given by prescription only. Although the Food and Drug Administration has banned many of these products, some potentially dangerous erectile dysfunction remedies remain on the market.
Faced with concern about ED pills and the heart, the FDA has urged caution in patients who have suffered heart attacks, strokes, or serious disturbances of the heart's pumping rhythm in the previous six months, in men with a history of congestive heart failure or unstable angina, and in men with low blood pressure or uncontrolled high blood pressure (above 170/110 mm Hg). Because certain medications can boost the blood levels of these drugs, men taking erythromycin or certain antifungal or anti-HIV medications should use only low-dose PDE-5 inhibitors. Reduced dosage is also important for men with advanced age and for those with significant kidney or liver disease.
"The answer to the question, 'Can patients with heart disease safely have sex?' is almost always 'Yes,' unless they have such bad heart failure or severe artery disease that even a moderate amount of exertion will cause terrible chest pain," says Richard Stein, MD, who is director of preventive cardiology at New York City's Beth Israel Hospital. "And if that is the case, sex is probably the last thing on their minds anyway."
Usually patients will try less invasive alternatives to treat impotence before opting for surgery. These alternatives may include supplements, herbs, lifestyle changes and even medications. In cases where other treatments do not work to resolve ED, surgery might be a last-resort option. Surgery involves implanting a penile prosthesis. This is a saline-filled silicone device or a malleable device. Although the likelihood of serious side effects is considered to be low, certain risks are associated with surgery to correct erectile dysfunction. These side effects may include: anesthetic risk, device infection, and device malfunction or mechanical failure. Some studies have found that five years following surgery around 10–20 percent of men experience device malfunction and failure. Infection rates are low. Around one percent of men who opt for this type of surgery get an infection.

Guidelines recommend that phosphodiesterase type 5 (PDE5) inhibitors are the first-line drug for the treatment of ED (Table 1). Sildenafil citrate was the first oral drug approved for ED in the US.59 The newer PDE5 inhibitors include vardenafil, tadalafil and avanafil. The inhibition of PDE5 enhances cyclic guanosine monophosphate (cGMP)-NO-mediated vasodilatation by preventing PDE5 catabolism of cGMP and so delaying detumescence. PDE5 inhibitors increase the number and duration of erections, as well as the percentage of successful sexual intercourse.60
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.

Figure. Progression of atherosclerosis. Endothelial dysfunction occurs early in atherosclerosis and prevents blood vessels from dilating properly. When the blood vessels that supply the penis are not able to dilate during sexual stimulation because of endothelial dysfunction, the penis cannot fill with blood, and the man develops erectile dysfunction. As atherosclerosis progresses, plaques build up in blood vessels and blood flow is slowed, further worsening erectile function. A heart attack occurs when an atherosclerotic plaque in a coronary artery ruptures, a blood clot forms over the plaque, and blood flow to the heart muscle is completely blocked. Atherosclerotic risk factors (black arrows) worsen cardiovascular health; modification of these risk factors (red arrows) improves cardiovascular health.

Impotence, also known as erectile dysfunction or ED, is a very common problem, affecting up to half of 40-70 year old men in Australia.Treatment techniques for impotence have varied through the years, from external steel mechanical attachments, to static electricity attached to the penis and testicles, to simple aphrodisiacs such as oysters. Until as recently as 1970, erectile failure was almost always seen as being due to psychological causes and was usually treated with psychotherapy.Since then, the medical causes contributing to impotence have been recognised and the treatment of impotence has been revolutionised, providing a range of options which are far more acceptable and very much more successful.Treatment options for impotenceTreatment choices for erectile dysfunction include:medicines;self-injection therapy;devices such as vacuum pumps;penile implant surgery;hormone therapy; andcounselling.If you have erectile dysfunction, the treatment your doctor recommends will depend on the severity of symptoms and the underlying cause of your impotence.Your doctor will want to check that any conditions that could be contributing to or causing erectile dysfunction are being treated.Your doctor may also suggest that you make some lifestyle adjustments, such as:increasing the amount of physical activity you get;losing weight if you are overweight;reducing the amount of alcohol you drink;quitting smoking; andnot taking illicit drugs.These lifestyle recommendations can help improve impotence related to several causes and improve your health in general.Medicines for erectile dysfunctionThe first tablet available for erectile dysfunction, sildenafil (brand name Viagra), has been largely responsible for helping to bring the topic of erectile dysfunction out into the open. Similar medications — tadalafil (Cialis) and vardenafil ( Levitra) — are also available. These medicines all work in a similar way, although there is some difference in how long their effect lasts. Sildenafil, tadalafil and vardenafil belong to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors because they block the PDE5 enzyme.How do oral medicines help treat erectile dysfunction?PDE5 inhibitors help in the process of getting and keeping an erection by working on chemicals in the body that are involved in erections. These medicines work by stopping PDE5 from breaking down an erection-producing chemical called cyclic guanosine monophosphate (cGMP). cGMP helps to relax the smooth muscle cells in the penis's erectile tissue, allowing more blood to flow into the penis to cause an erection. When PDE5 is temporarily blocked by these medicines, it can’t break down the erection producing cGMP, so an erection can be achieved and maintained. PDE5 inhibitors can be used in the treatment of erectile dysfunction that is due to physical or psychological causes.Medications such as Viagra, Cialis and Levitra will work only if you are sexually stimulated. They are not aphrodisiacs and won’t increase your sex drive.Side effects of PDE5 inhibitorsSide effects of these medicines can include headaches, flushes, blocked nose, indigestion and dizziness.In rare situations, sildenafil and vardenafil can cause a distortion of vision or change in colour vision.Tadalafil has been associated with back pain.Who can take medicines for impotence?PDE5 inhibitors cannot be taken by all men, so your doctor will need to evaluate your suitability before prescribing either of these medications.Men taking nitrates (often used to treat angina) should never take phosphodiesterase type 5 (PDE5) inhibitors. PDE5 inhibitors should also not be taken with some medicines used to treat high blood pressure.PDE5 inhibitors may also not be suitable for men with certain heart conditions or low blood pressure. Check with your doctor to find out if this type of medication may be suitable for you.Self-injection therapySelf-injection therapy delivers a medicine called alprostadil (brand name Caverject), also known as prostaglandin E-1, to the erectile tissue of the penis. Prostaglandin E-1 occurs naturally in the body and helps increase the blood flow to the penis to cause an erection. Unlike the PDE5 inhibitors, alprostadil will cause an erection whether the penis is stimulated or not.Self-injection therapy is usually recommended if PDE5 inhibitor medicines are not suitable or have not been effective in the treatment of erectile dysfunction.How to use self-injection therapyAlprostadil is injected into either of the 2 cigar-shaped chambers of the penis known as the corpora cavernosa, which run along the length of the penis, one on either side. Your doctor or urologist (specialist in problems with male reproductive organs and the urinary tract) will give you instructions on how to do this.Alprostadil should produce an erection in 5 to 20 minutes and, generally, the erection will last for 30 to 60 minutes.You should not use alprostadil more than once in a 24-hour period, and you should use it no more than 3 times a week.Don’t try to use more than the recommended dose of alprostadil, as your erection may last longer than is medically safe.Who can use self-injection therapy?You should ask your doctor if alprostadil is suitable for you. Your doctor will also be able to tell you how much alprostadil to use, depending on your condition and whether or not you are taking any other medications, and also how to use alprostadil properly.People with certain illnesses, such as leukaemia and sickle cell anaemia, or who have a penile implant or Peyronie’s disease, where the penis may be scarred and produces erections that are not straight, should not use alprostadil.Men for whom sexual activity is not advised should not use alprostadil.Side effects of injection therapyThe most common side effects of alprostadil include pain in the penis or bruising in the penis at the site of injection. Fibrosis (the development of fibrous tissue) can also develop following injections into the penis.The most serious side effect is priapism (a persistent erection), which is a medical emergency. Your doctor will inform you of what to do if you have an erection that persists for 2 hours or more. It is very important that you follow your doctor’s instructions and inform them that you have experienced this side effect.Vacuum erection devicesVacuum erection devices work by creating a vacuum, which increases blood flow to the penis, producing an erection.The penis is lubricated and placed inside a hollow plastic chamber. Air is pumped out of the chamber, either manually or by a battery powered pump. This creates a vacuum which pulls blood into the penis to cause an erection. This takes about 5 minutes.Once the penis is erect, the man fits a rubber ring around the base of his penis to keep the blood trapped inside the penis when the cylinder is removed. After intercourse, the ring can be removed to return the penis to a limp state.Vacuum erection devices avoid surgery and can be used as often as required. However, they may be difficult to use, and many men and their partners feel they take much of the pleasure and spontaneity away from sexual activities. Vacuum pumps are not suitable for men who have problems with blood clotting, or blood disorders such as leukaemia.Penile implant surgery for impotencePenile implant surgery is not a common procedure but in some cases it may be the most appropriate treatment for erectile dysfunction.The procedure involves placing an implant inside the penis, along its length, so that it can become erect. The implant may be a pair of semi-rigid rods or a pair of inflatable cylinders.The inflatable implants allow the penis to look and feel limp (flaccid) or erect, depending on how much the cylinders are inflated. The cylinders in an inflatable implant are hollow, and the man gets an erection by squeezing a pump located in his scrotum to fill the cylinders with salt water (saline) stored in a reservoir implanted in his lower abdomen. A release valve drains the saline out of the cylinders and back into the reservoir.With the semi-rigid, malleable rod type of implant, the rods run along the length of the penis and can be bent upwards to produce an erect penis, or downwards when an erect penis is not required.Like all surgery, there are some risks, such as infection or bleeding. If you have had surgery and have severe pain, fever, swelling or excessive bleeding, you should contact your doctor as soon as possible.Vascular surgery for erectile dysfunctionIn cases where a man’s anatomy prevents blood flow into or out of the penis, vascular surgery may be an option. This treatment option is rarely recommended, and is usually only successful in younger men.If there is a blockage that prevents blood from flowing into the penis, a doctor may recommend an operation that bypasses the blocked blood vessels, using a length of vein or manufactured tubing, to allow more blood to flow into the penis and help produce an erection.If the problem is that blood leaks back out of the penis, this can be corrected by tying off the major veins that drain the penis, a procedure known as venous ligation.Hormone treatments for impotenceIn a small number of men, blood tests may show abnormally low levels of testosterone, the male sex hormone. In such cases your doctor might prescribe a course of testosterone injections or a testosterone implant. The supplements can help boost sex drive as well as increasing the ability to have erections. Testosterone gel or patches, applied daily to the skin, are another option.Complementary medicines for erectile dysfunctionThere is a lack of scientific evidence supporting the effectiveness of complementary therapies for the treatment of impotence.Always check with your doctor before taking any herbal medicines or supplements for impotence. These formulations may contain ingredients that can interact with other medicines or cause dangerous side effects.Counselling for men with impotenceErectile dysfunction often has physical causes, but sometimes there is a psychological basis for erection problems. Often this is a form of performance anxiety. A man may have had an episode of erectile dysfunction due to some passing cause like fatigue, stress, relationship difficulty or intoxication. This may have led to embarrassment or a feeling of failure. Even if the physical cause does not remain, future attempts to have sex may trigger memories of this embarrassment and acute anxiety that it will happen again. This anxiety itself is capable of causing erectile dysfunction, and so a man may get trapped in a self-reinforcing cycle of anxiety and erectile dysfunction. In these instances, seeing a GP, counsellor or psychologist can be very helpful.Stress, anxiety, depression and low self-esteem, in fact, almost all significant emotional problems, can have a major effect on sexuality. So do many chronic physical illnesses, even if they don't directly affect genital function. Counsellors and psychologists can assist with these and a wide range of other sexual and relationship problems and can also help female partners suffering from sexual problems. They are particularly skilled in helping patients to overcome guilt or anxiety relating to sexual abuse, and in helping couples to sort out relationship difficulties. Simple problems can be dealt with in a few visits, but more complex problems may require several months or even years of therapy.Your doctor may be able to recommend a psychologist or counsellor who specialises in sexual and relationship problems.

The research is based on a Swedish national database of health records that includes all hospitals in Sweden. Researchers analyzed the records of men age 80 years or younger who were hospitalized for a first heart attack between 2007 and 2013. Tracking the men for an average of 3.3 years following this first heart attack, they compared outcomes among those who subsequently filled a prescription for a PDE5 inhibitor or alprostadil to those who did not. Overall just over 7 percent of men were prescribed an erectile dysfunction drug, 92 percent of whom were prescribed a PDE5 inhibitor and 8 percent of whom were prescribed alprostadil.
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.

Since erectile dysfunction presents such an intimate relationship with CV parameters, it is easily deducted that it could constitute a powerful tool for detecting asymptomatic CV disease. Consequently, recognition of sexual dysfunction in a hypertensive individual should prompt further diagnostic procedures and therapeutic interventions in order to disclose its silent cardiovascular risk and improve patient’s quality of life and life expectancy.
Abnormalities in the vascular, neural, endocrine, muscular, or psychiatric systems can result in ED.2,3 EDDM is due to multisystemic disease. Atrophy or apoptosis of cavernosal smooth muscle can occur due to loss of Bcl-2 expression in cavernosal smooth muscle and lead to ED. Abnormal amounts of advanced glycation end products is a common occurrence. These chemicals may have an effect on potassium channels that facilitate intracellular calcium release and subsequent cavernosal smooth muscle relaxation. Connective tissue synthesis is increased due to transforming growth factor-beta. The decrease in smooth muscle and the increase in collagen decreases the compliance of the erectile tissue. Neuropathic damage to both the somatic and autonomic nerves has been clearly defined in DM. Partial occlusion of the pelvic or intracavernosal arteries, hypogonadotropic hypogonadism, and depression associated with a chronic illness (DM) can all play a primary or secondary role in the development of EDDM. On a molecular level, studies have demonstrated decreased levels of endothelial and neuronal nitric acid synthase (NS) and decreased cavernosal artery and sinusoidal response to nitric oxide. Abnormalities in nitric oxide rapidly render the functional syncytium of the corpora cavernosa unable to synchronously relax. As the patient with diabetes ages, the concentration of constrictors, including endothelin, prostanoids, and possibly angiotensin, increases as the production of the relaxants, including nitric oxide, vasointestinal peptide, and prostacyclin, decreases.

Heart disease describes a range of conditions that affect your heart. Diseases under the heart disease umbrella include blood vessel diseases, such as coronary artery disease; heart rhythm problems (arrhythmias); and heart defects you’re born with (congenital heart defects), among others.The term “heart disease” is often used interchangeably with the term “cardiovascular disease.” Cardiovascular disease generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke. Other heart conditions such as those that affect your heart’s muscle, valves or rhythm, also are considered forms of heart disease.

At the same time, people with diabetes are susceptible to a type of blood vessel damage known as endothelial dysfunction. A recent study found that men with ED are at a greater risk of heart disease, which is also associated with endothelial dysfunction. If blood vessels aren't in good working order, the penis may not get enough blood for an erection.
Eastern medicine should be fully exploited, and integrated with modern medicine to combine the advantages of both TCM and Western medicine. More research should be conducted into the efficacy and safety of TCM, and integration of TCM and Western medicine may provide promising breakthroughs in future clinical treatment. This strategy may allow for the development of new therapeutic strategies based on concepts of TCM and integrated medicine. There is a need for multimodal therapy and holistic approach to treat men (and their partners) with ED through complementary use of herbal supplements and modern drug to optimize underlying medical comorbidities; acupuncture, exercise or massage to reduce stress and strengthen the body; introduction and escalation of various medical therapy with use of mechanical therapy to further enhance penile erection; and lastly surgical intervention in suboptimal or refractory ED cases.

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.
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.
In the past 6 years, the FDA has approved three oral agents for the treatment of ED: sildenafil, vardenafil, and tadalafil. All three are phosphodiesterase type 5 (PDE-5) inhibitors and work by potentiating the effect of nitric oxide in the penis. In particular, they block the hydrolysis of cyclic guanosine monophosphate to guanosine 5'-monophosphate, thus enhancing nitric oxide–mediated smooth muscle relaxation, increasing blood flow to the penis and facilitating erection.

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
Since time immemorial, TCM has been adopted by many cultures and is widely practiced in Asian countries despite paucity of level 1 clinical evidence and limited published safety records. TCM is more congruent with Asian values, beliefs and philosophical orientation to health, simple administration, readily available and ease of access or procurement, and general belief that TCM is safer. While Asian males are clearly different from their Western counterparts with respect to biology, culture and beliefs, the practice of TCM appears to be adopted by many Western nations lately. Many men seek TCM to avoid embarrassing visits to physicians and potential side effects of pharmaceutical drugs, or after becoming frustrated with the outcome of modern medicine. Patients are choosing to take more responsibility for their health by exploring a variety of non-pharmaceutical drugs and wellness practices. Furthermore, TCM such as herbal medicine does not address a specific organ system only and is meant to restore and realign the vital energy within the body, which is responsible for ageing, clinical diseases and the deterioration of bodily function; while in Western medicine, each pill is intended for a specific organ/system and that a patient may need a collection of pills to treat multiple comorbidities, rendering modern medicine less attractive to TCM.
Branded Viagra can now be bought over the counter in pharmacies, but please check with your GP first if you have a medical condition. It's important to use a reputable pharmacy, as there is a large market in counterfeit drugs for erectile dysfunction, especially over the internet. These contain varying amounts of the active ingredient and sometimes completely different drugs.
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.
Some research even suggests the effect of blood pressure drugs may be more psychological than physical. When ED occurs after a man begins to take a new medication, it's possible that anxiety about his health, rather than the medication, may trigger the problem. And being aware of possible side effects may make a man more likely to recognize them as abnormal.
In a prospective human phase 1 open-label and single-arm study reported by Haahr et al. (27), 17 men with refractory post radical prostatectomy ED were given a single intracavernosal injection of autologous adipose-derived regenerative cells (ADRCs) freshly isolated after a liposuction. The procedures were well-tolerated and over a 6-month follow-up period, 8 of 17 men showed improvement of their erectile function.
Crossref | PubMed | Scopus (174) | Google ScholarSee all References All these men had ED and twice underwent symptom-limited supine bicycle exercise echocardiography 1 hour after taking either sildenafil (50 mg or 100 mg) or placebo. This study found no significant changes in resting heart rate, diastolic blood pressure level, or wall motion score index, and the exercise capacity of the 2 groups was similar. Both groups had similar numbers of patients who experienced dyspnea and/or chest pain, had a positive exercise echocardiographic test, and had exercise-induced wall motion abnormalities. Sildenafil caused a mean decrease of 7 mm Hg in the resting systolic blood pressure level compared with the placebo group. In conclusion, this study showed that in patients with stable coronary artery disease, sildenafil caused no change in symptoms, exercise endurance, or presence/extent of exercise-induced ischemia as measured by exercise echocardiography.
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

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.
High blood pressure, otherwise known as hypertension, can contribute to erectile dysfunction (ED). Some of the medications used to treat high blood pressure can cause ED as well. According to the authors of one study, about 30 percent of men with high blood pressure also have had ED. Finding a medication that treats high blood pressure without causing ED is a goal of many men.
ED is a common disease affecting men with IHD. Endothelial dysfunction is the link between ED and IHD and both diseases share the same aetiology, risk factors and pathogenesis. Aggressive control of these risk factors – along with lifestyle modification – is recommended to improve symptoms of ED and reduce cardiovascular risk. PDE5 inhibitors remain the first-choice treatment for ED in IHD patients and they have been shown to be safe and effective. However, PDE5 inhibitors can potentiate the hypotensive effect of nitrates so concomitant administration of sildenafil and nitrates is contraindicated. Gene and stem cell therapy are being investigated as a future therapies for ED.
The American College of Cardiology is a 52,000-member medical society that is the professional home for the entire cardiovascular care team. The mission of the College is to transform cardiovascular care and to improve heart health. The ACC leads in the formation of health policy, standards and guidelines. The College operates national registries to measure and improve care, offers cardiovascular accreditation to hospitals and institutions, provides professional medical education, disseminates cardiovascular research and bestows credentials upon cardiovascular specialists who meet stringent qualifications.
Stem cell therapy is an attractive treatment modality and an appealing option for tissue regenerative therapy for ED. Stem cells are pluripotent cells that can be produced from multiple regions within the body. They have the potential to divide and differentiate into numerous kinds of human cells, such as endothelial cells and smooth muscle.79 The efficacy and safety of gene and stem cell therapy in patients with ED and IHD need to be extensively investigated because both seem to have the potential to correct underlying abnormalities in ED. This would be a huge development in terms of management options for patients with ED and IHD.
It's an all too common problem: Roughly half of men with diabetes—and up to 25 percent of men overall—experience erectile dysfunction (ED) at some point in their lives. And it's a complicated problem, too, with diverse physical origins and complex emotional ramifications. Yet diabetes-related ED needn't be a no-sex sentence for men. There are ways to avoid this disorder and to treat it at any age. While much of the research on ED is still in its infancy, here is what science has to say so far.

At the same time, people with diabetes are susceptible to a type of blood vessel damage known as endothelial dysfunction. A recent study found that men with ED are at a greater risk of heart disease, which is also associated with endothelial dysfunction. If blood vessels aren't in good working order, the penis may not get enough blood for an erection.

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.
