Physical and emotional stress — whether over-exercising, under-sleeping or just dealing with everyday stressors like work and a busy schedule — causes an increase in “stress hormones,” including cortisol and adrenaline. Stress can lower desire for sex. This is because stress can contribute to fatigue or preoccupation with other tasks. It can also significantly affect blood flow by increasing inflammation.
The safety of PDE5 inhibitors in patients with IHD has been shown in multiple trials. Arruda-Olson et al. investigated the safety of sildenafil during exercise stress tests in patients with IHD to ascertain whether the drug induces or exacerbates myocardial ischaemia. This was a prospective, randomised crossover study that demonstrated safety of sildenafil when given 1 hour before an exercise stress test.69 Another study that investigated 120 trials of sildenafil revealed that the rates of MI and cardiovascular death with sildenafil are as low as with placebo.70

Erectile dysfunction is very common as men age. Erectile dysfunction is frequently a sign of atherosclerosis, a clogging or narrowing of the blood vessels that causes heart attacks. Erectile dysfunction usually comes 3 to 5 years before a heart attack, so after ED is diagnosed, there is time to treat atherosclerosis and prevent a heart attack. Treating atherosclerosis involves diet, exercise, and medications, if necessary. Talk with your doctor about a broken sex life, and you might be able to prevent a broken heart.

Table 3 is a suggested algorithm for the assessment of patients and their further categorization and handling. There are parts of investigation that are common for patients both with and without CVD, while additional elements of investigation are helpful in categorizing the patient without CVD to the appropriate risk category. Determination of exercise ability and stress testing is crucial to the assessment (see also below ‘Exercise ability: the risk of sexual activity’). Patients without established CVD or diabetes should be evaluated for their risk of future events according to risk scores (SCORE or Framingham). Patients with established CVD or diabetes are by default considered at increased risk. Patients with adequate exercise ability or a negative stress test can initiate or resume sexual activity and begin treatment for ED. In patients with a positive stress test or in high-risk patients, sexual activity should be deferred until the cardiac condition has been treated and stabilized. In all cases, patient follow-up and reassessment is recommended.
Nonsustained erection with detumescence after penetration is most commonly caused by anxiety or the vascular steel syndrome. In the vascular steel syndrome, blood is diverted from the engorged corpora cavernosae to accommodate the oxygen requirements of the thrusting pelvis. Questions should be asked regarding the presence or absence of nocturnal or morning erections and the ability to masturbate. Complete loss of nocturnal erections and the ability to masturbate are signs of neurological or vascular disease. It is important to remember that sexual desire is not lost with ED—only the ability to act on those emotions.
The medicine causes blood vessels to expand, increasing blood flow in the body and to the penis, thus helping patients to get an erection. Invasive surgeries that involve rods and balloons are also available to patients suffering from ED. While these treatments often come with potential side effects, discomfort and a financial burden, some ED patients may see success with them.
In contrast to Chinese ginseng, Korean ginseng is divided into three types, depending on how it is processed. Red Ginseng is harvested at the sixth year of cultivation and is steamed and dried. In addition to the effects mentioned regarding the effects of ginsenoside, red ginseng has been repoted to improve erectile function in a rat model of metabolic syndrome and it was also found to inhibit fibrosis of the corpus cavernosum of the penis (39). As with most herbal medicines, the concentration of ginsenoside are distributed unevenly throughout the ginseng plant and the concentrations in individual supplements can vary. Common side effects include headaches, insomnia, gastric upset, rash and constipation.

Viagra, Cialis, Levita, and Staxyn all work in a similar fashion and make it physically possible to get an erection when aroused. However, men whose blood pressure is poorly controlled and who take alpha-blockers for high blood pressure treatment should not take any of these treatments for erectile dysfunction as it may reduce blood pressure to critically low levels, causing fainting or sudden death. Also, you may be prohibited to use these drugs if you demonstrate any of the following:
** Indeterminate risk patients include diabetics, those with mild or moderate stable angina pectoris, past myocardial infarction (2-8 wks) without intervention awaiting exercise electrocardiography, congestive heart failure (NYHA class III), and noncardiac sequelae of atherosclerotic disease (eg, peripheral artery disease and a history of stroke or transient ischemic attack); this patient with ED may require assessment for additional vascular disease using carotid intima-media thickness or ankle-brachial index and subsequent reclassification to low or high risk.

Older age. A man’s risk increases past the age of 40, as age is the variable most strongly associated with impotence. This is due to changing hormones, higher risk for heart problems and those affecting circulation, and decreased sexual desire that often occurs with increasing age. For example, based on findings from the National Health and Social Life Survey, it’s been found that “men between 50–60 years old are more than 3 times as likely to experience erection problems and to report low sexual desire compared to men aged 18 to 29 years.” (3)
Before taking any medication for erectile dysfunction, including over-the-counter supplements and herbal remedies, get your doctor's OK. Medications for erectile dysfunction do not work in all men and might be less effective in certain conditions, such as after prostate surgery or if you have diabetes. Some medications might also be dangerous if you:
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.

The treatment of ED using TCM ties in with the treatment of late-onset hypogonadism (LOH). LOH occurs due to the breakdown in coordination between the heart and the kidneys, deficiencies of the spleen and kidney (yang), deficiencies of the liver and kidney (yin) and deficiencies of the kidney (yin and yang). The endocrine function of the pituitary and gonads becomes disordered with age due to a depression of overall function. This results in accumulation of free radicals and other toxins that cannot be relieved solely with male hormone supplementation. Warm yang can energize kidneys to benefit the body, remove toxins, invigorate qi and promote blood circulation. Free radicals are removed, blood fat regulated, cardio-cerebral blood flow improved and again the key here is to improve the function of the digestive, respiratory and endocrine systems, hence regulating the body in every aspect holistically (28).
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.
Erectile dysfunction (ED) is a common sexual problem affecting many men irrespective of cultures, beliefs and nationalities. While medical therapy for ED has been revolutionized by the advent of oral phosphodiesterase type 5 inhibitors and intracavernosal injection of vasoactive agents, recent technological advances such stem cell therapy, low intensity shock wave and newer generation of penile prosthesis implant offer hope to men who do not respond to conventional medical therapy. In contrast, traditional and complementary medicine (TCM) focuses on the restoration and better overall bodily regulation with the use of various herbal and animal products as well as exercises to invigorate qi (energy) in vital organs. Western medicine involves an analysis of ED symptom and underlying causes that contribute to ED, while TCM emphases the concept of holism and harmonization of body organs to achieve natural sexual life. The following article reviews our current understanding regarding the philosophical approach, and evaluates the evidence surrounding various ED therapies between mainstream Western Medicine and TCM.

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.
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 oral erectile dysfunction medicines to work as desired, they must be used properly in the first place. This means taking the medicine 30–45 minutes before engaging in sexual intimacy; taking the drug on an empty stomach or at least avoiding a heavy or high-fat meal before taking the drug (this is especially important when using sildenafil); and engaging in adequate genital stimulation before attempting intercourse. Drinking small amounts of alcohol (one to two drinks) should not compromise the effectiveness of erectile dysfunction medicines, but larger amounts of alcohol can diminish a man’s ability to have an erection.
