“With the success of Viagra-type drugs, there has been a tendency to start all patients with ED on one of these drugs and not look much further for a medical cause. But we now know that ED may be an early warning for heart and blood vessel disease, so it is important to look for common risk factors. These include high blood pressure, diabetes, medications, smoking, drinking, and drugs,” said Dr. Wang.
ED is often the result of atherosclerosis, and as a result, men with ED frequently have cardiovascular disease. Sexual activity is associated with increased physical exertion, which in some men may increase the risk of having a heart attack (myocardial infarction or MI). The major risk factors associated with cardiovascular disease are age, hypertension, diabetes mellitus, obesity, smoking, abnormal lipid/cholesterol levels in the blood, and lack of exercise. Individuals with three or more of these risk factors are at increased risk for a heart attack during sexual activity. The Princeton Consensus Panel developed guidelines for treating ED in men with cardiovascular disease. Thus, if you have ED and cardiovascular disease (for example, angina or prior heart attack), you should discuss whether or not treatment of ED and sexual activity are appropriate for you.
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.
Yes, excessive alcohol intake can affect sexual function. Erectile dysfunction is more common in people who abuse drugs and alcohol. Lifestyle changes such as drinking less alcohol and quitting smoking may help improve sexual function. Chronic heavy alcohol consumption can affect erectile ability through altered hormone metabolism and nervous system involvement.
Though it's most common among older men, it's possible for young men to get erectile dysfunction. When young men develop ED, it's usually a result of psychological problems such as anxiety, stress, depression or relationship problems. However, physical problems such as diabetes, nerve problems, injury or other medical conditions may also lead to erectile dysfunction in younger men. If you're having frequent or ongoing trouble getting or keeping an erection long enough to have sex, talk to your doctor.
No matter what the cause of erectile dysfunction, it is likely to cause feelings of stress and other emotional reactions. It’s also not uncommon for erection problems to cause tension in a relationship, particularly if one or both partners withdraws emotionally and the problem is not talked about. And it’s possible for a man’s renewed ability to have intercourse after a period of no sexual activity to stir up relationship issues.

Dr. Jonas Bovijn is the co-first author of the study and is from the Big Data Institute at the University of Oxford. He said: “We know that there is observational evidence linking erectile dysfunction and type 2 diabetes, but until now there has not been definitive evidence to show that predisposition to type 2 diabetes causes erectile dysfunction.”
If not properly controlled, both type 1 and type 2 diabetes can cause complications due to high blood sugar levels. Over time, these high levels can cause irreversible nerve damage and narrow your blood vessels. While nerve damage may affect the sensitivity of your penis, blood vessel damage can affect the blood flow to your penis and make it more difficult for you to get an erection.
This man’s history is adequate to rule out arterial or venous insufficiency as he can masturbate to produce a rigid, sustainable erection and he responds well to tadalafil. Due to his report of gradual onset, his lack of response to ongoing sexual therapy, and his tremendous anxiety associated with the issue, the decision was made to offer a PCDU to assess for a vascular etiology for his disorder. PCDU revealed normal peak flow bilaterally of 40 cm/sec with no end diastolic flow and 100% rigidity obtained. His erection lasted more than 2 hours and required phenylephrine to resolve the erection.

It's not easy to get in the mood when you're overwhelmed by responsibilities at work and home. Stress can take its toll on many different parts of your body, including your penis. Deal with stress by making lifestyle changes that promote well-being and relaxation, such as exercising regularly, getting enough sleep, and seeking professional help when appropriate.
An alprostadil cream that patients apply into the tip of the penis (the urethral meatus, the opening that urine passes through) is currently available in the UK and Europe. It is currently under review by the U.S. Food and Drug Administration (FDA). After application of the cream, an erection occurs within five to 30 minutes, and the erection lasts one to two hours in men who respond to the cream. Doctors recommend that one use the cream for a maximum frequency of two to three times per week and no more frequent than once every 24 hours. It has essentially the same contraindications and side effects as the other formulations of alprostadil. The cream may cause vaginal burning in roughly 4% of partners. Men should not use alprostadil cream for sexual intercourse with women of childbearing potential unless a condom is used. Researchers have performed controlled trial studies to evaluate the safety and effectiveness of this drug. Overall, 52% of men reported improvement in their erections compared to 20% of men receiving placebo. A later analysis demonstrated that 36% of men using the alprostadil cream had a clinically relevant improvement in vaginal penetration ability and 31% clinically relevant improvement in ability to have successful intercourse to ejaculation.

As blood flows into the penis, the corpora cavernosa swell, and this swelling compresses the veins (blood vessels that drain the blood out of the penis) against the tunica albuginea. Compression of the veins prevents blood from leaving the penis. This creates a hard erection. When the amount of cGMP decreases by the action of a chemical called phosphodiesterase type 5 (PDE5), the muscles in the penis tighten, and the blood flow into the penis decreases. With less blood coming into the penis, the veins are not compressed, allowing blood to drain out of the penis, and the erection goes down.

Experts often treat psychologically based impotence using techniques that decrease anxiety associated with intercourse. The patient's partner can help apply the techniques, which include gradual development of intimacy and stimulation. Such techniques also can help relieve anxiety during treatment of physical impotence. If these simple behavioral methods at home are ineffective, a doctor may refer an individual to a sex counselor.
Erectile dysfunction: Dehydration causes decreased blood volume and increased angiotensin, a hormone associated with erectile dysfunction. Long-term alcohol abuse can cause damage to the nervous system, which is responsible for triggering the signals that cause an erection. Studies have also shown that prolonged abuse can cause irreversible damage to the nerves in the penis. Additional studies have shown erectile dysfunction is present in alcohol abusers even when they are sober.
Erectile dysfunction, also known as impotence, is defined as not being able to get or keep an erection firm enough for sex. Remember, occasional erectile dysfunction is not uncommon, but if it’s persistent, erectile dysfunction can be the sign of a more serious health issue, and so you should visit your doctor.Here are 8 surprising causes of erectile dysfunction:High cholesterol. Having a raised cholesterol increases the risk of atherosclerosis where the arteries become narrowed and clogged, resulting in impaired blood flow. When this happens to the arteries in the penis, it can prevent enough blood to create an erection from reaching the penis.Depression. This can cause a lack of interest in sex. See your doctor if this happens to you.Smoking. Smoking causes damage to blood vessels, including those that supply the penis which can result in difficulty in achieving an erection.Cycling. Long hours in the saddle without changing position can cause compression of the perineal nerves and blood vessels, resulting in nerve damage which causes erectile dysfunction. Some saddles are worse than others. If cycling is causing you symptoms of tingling or numbness in your penis, adjust your riding position and take a break.  You might want to look at a different saddle, too. Rodeo riding can have the same effect.Medicines. Erectile dysfunction can be a side-effect of many medicines, including some antipsychotics and antidepressants, cholesterol-lowering medicines, high blood pressure medicines, and epilepsy medicines.Stress. Feelings of stress and anxiety can overflow onto your sex life, and you may find you can’t perform as well as you normally could. 'Performance anxiety' is a common cause of erectile problems.Diabetes. Diabetes raises the risk of erectile dysfunction threefold by its effects on nerves and blood vessels.Peyronie’s disease. This disease causes curvature of the penis due to a hardened area of scar tissue, which results in pain when the man has an erection.If you suffer from erectile dysfunction, don’t be embarrassed – it affects one in 5 men over 40. Remember your doctor can help identify the cause of your erectile dysfunction,  and put you on the path to successful treatment. Read erectile dysfunction – visiting your doctor to find out what to expect when you visit your doctor. Last Reviewed: 18 February 2016
There is also a significant population, which has psychogenic sexual dysfunction, which is likely in a situation of marital conflict, which commonly exists in the families of alcoholics.[18] There is some evidence of this with more than a third of the subjects reporting dissatisfaction with their spouses' responses and / or decreased frequency. This cannot be conclusive without data on nocturnal erection or sexual activity in alternate situations. One of the limitations of this exploratory study is that marital functioning was not specifically assessed.
Obesity. Obesity itself is not a risk factor for ED — but there is a connection. “The bigger concern is that obesity can lead to type 2 diabetes or vascular diseases, which are risk factors for ED,” says Montague. Morbid obesity, a term used to classify individuals who are significantly overweight, can cause hormonal changes that are triggered by excess body fat. In addition, obesity can put physical limitations on sexual intercourse.
There are two kinds of surgery for ED: one involves implantation of a penile prosthesis; the other attempts vascular reconstruction. Expert opinion about surgical implants has changed during recent years; today, surgery is no longer so widely recommended. There are many less-invasive and less-expensive options, and surgery should be considered only as a last resort.
