The causes of erectile dysfunction include aging, high blood pressure, diabetes mellitus, cigarette smoking, atherosclerosis (hardening of the arteries), depression, nerve or spinal cord damage, medication side effects, alcoholism or other substance (drug) abuse, pelvic surgery including radical prostatectomy, pelvic radiation, penile/perineal/pelvic trauma such as pelvic fracture, Peyronie's disease (a disorder that causes curvature of the penis and sometimes painful erections), and low testosterone levels.

This patient has thoroughly researched erectile dysfunction on the internet and has a powerful knowledge base from which he draws reference. He is also emotionally labile. The most urgent recommendation for this patient is that he seek appropriate psychiatric treatment to help in management of his psychiatric conditions and suicidal ideation. It was also recommended that he seek care with a sexual therapist to work through additional issues related to his “addiction” to masturbation. During his urologic visit we performed both cold and hot perception testing and biothesiometer, which were normal. He was displeased with these findings as they were incongruent with his chief complaints; normal results caused him to become tearful. A penile ultrasound was performed without injection of a pharmacologic agent to assess the appearance of his cavernous tissue and cavernous arteries, which had normal appearance and measurement, respectively, on ultrasound. (This quick bedside procedure has the potential to be both diagnostic and therapeutic for the patient; the importance of this cannot be underestimated).


The surgery for placement of a penile prosthesis is typically an outpatient surgery. Doctors often perform a penile prosthesis through a single incision, and all of the components are hidden under the skin. Health care professionals often give patients antibiotics at the time of surgery and often after the surgery to decrease the risk of developing an infection. Depending on your health history, a health care provider may leave a catheter in your penis to drain your bladder overnight.
Men with a rare heart condition known as long QT syndrome should not take vardenafil since this may lead to abnormal heart rhythms. The QT interval is the time it takes for the heart's muscle to recover after it has contracted. An electrocardiogram (EKG) measures the QT interval. Some people have longer than normal QT intervals, and they may develop potentially life-threatening abnormal heart rhythms, especially when given certain medications. Men with a family history of long QT syndrome should not take vardenafil, as it is possible to inherit long QT syndrome. Furthermore, vardenafil is not recommended for men who are taking medications that can affect the QT interval such as quinidine (Quinaglute, Quinidex), procainamide (Pronestyl, Procan-SR, Procanbid), amiodarone (Cordarone), and sotalol (Betapace).
Erectile dysfunction is when a man either can’t have an erection or can’t keep an erection long enough to have sex. For only 20% of men with ED, the cause is due to a psychological problem or disorder.2 When the cause of your ED is due to a physical condition, your ED is not a reflection on you or your sexual partner, since lack of arousal isn’t the problem.
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.

Few men want to talk about their inability to get or maintain an erection, however, erectile dysfunction can have a profound impact on relationships and self-esteem. Fortunately, trouble in the bedroom doesn't necessarily mean you're dealing with erectile dysfunction. Most men will have problems with an erection at some point in their sexual history. But one bad day in the bedroom doesn't mean major sexual health problems. So how can you know if you're dealing with erectile dysfunction?
Unfortunately, studies specifically considering the relationship between couple liaison and ED in younger men are not available. Although the aforementioned studies include also young men, thus making their results theoretically applicable even in this specific group, it should be recognized that mean age of men enrolled is usually shifted toward the middle-age, rather than younger age. It is conceivable that couple relationship can act differently in younger men because it could show peculiar characteristics likely affecting ED onset, maintenance, resolution or responsiveness to therapies, including the short duration, lack of experience in both the partners, limited privacy, fears for emotional involvement or worry for undesired pregnancies.
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.
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.
Neurologic illnesses leading to ED have been recently reviewed (64). The most common of them (i.e., consequences of prostatic surgery, stroke and Parkinson’s disease) are not typical of younger age and, similarly to conditions less common but more typical of younger men, such as spinal cord injury, multiple sclerosis and spina bifida, the clinical features of the underlying disease are clearly apparent, being ED one of the multiple manifestations, rather than a harbinger of a subtle condition. Diagnosis of neurologic origin of ED is often quite simple, based on medical history and physical exam. The clinical management is a multidimensional and coordinated work of rehabilitation and medical therapy, which includes ICI injection of vaso-relaxant drugs, vacuum device and surgery (64).
Another risk factor is that men with type 2 diabetes may produce less than normal amounts of testosterone, a condition called hypogonadism. A 2007 study found that one-third of men with type 2 diabetes had low testosterone levels. Those men were also more likely to have ED, though the link may have to do with weight, not diabetes per se. Being overweight or obese is a risk factor for hypogonadism.

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.

Sildenafil should be taken 1–2 h before intercourse. It is important to tell patients that the drug’s effectiveness requires sexual stimulation. One patient in our clinic recently complained that he had no effect from taking sildenafil. It was later discovered that he took the pill and then sat on his couch and read a book about how to grow tomatoes!

Epidemiological studies consistently show that prevalence of erectile dysfunction (ED) increases with ageing. Nonetheless, complaints of ED even in younger men are becoming more and more frequent. Healthcare professionals working in Sexual Medicine but even those operating in different clinical contexts might be adequately prepared to answer this increasing requirement. ED in younger men is likely to be overlooked and dismissed without performing any medical assessment, even the most basic ones, such as collection of medical history and physical exam. This is due to the widespread assumption that ED in younger individuals is a self-limiting condition, which does not deserve any clinical evaluation or therapy and can be managed only with patient reassurance. However, evidence shows that, in younger subjects, organic, psychological and relational conditions can contribute to the pathogenesis of ED and all these conditions might be evaluated and treated, whenever necessary. Among the organic conditions contributing to the onset of ED, metabolic and cardiovascular (CV) risk factors are surprisingly of particular relevance in this age group. In fact, in younger men with ED, even more than in older ones, recognizing CV risk factors or conditions suggestive of cardio-metabolic derangements can help identifying men who, although at low absolute risk due to young age, carry a high relative risk for development of CV events. In this view, the assessment of a possible organic component of ED even in younger individuals acquires a pivotal importance, because it offers the unique opportunity to unearth the presence of CV risk factors, thus allowing effective and high quality preventive interventions.

Sexuality and erection are controlled by multiple areas of the human brain including the hypothalamus, the limbic system, and the cerebral cortex. Stimulatory or inhibitory messages are relayed to the spinal erection centers to facilitate or inhibit erection (5). Two mechanisms have been proposed to explain the inhibition of erection in psychogenic dysfunction: direct inhibition of the spinal erection center by the brain as an exaggeration of the normal suprasacral inhibition and excessive sympathetic outflow or elevated peripheral catecholamine levels, which may increase penile smooth muscle tone and prevent the relaxation necessary for erection (8). Animal studies demonstrate that the stimulation of sympathetic nerves or systemic infusion of epinephrine causes detumescence of the erect penis (6,7). Clinically, higher levels of serum norepinephrine have been reported in patients with psychogenic ED than in normal controls or patients with vasculogenic ED (9).

Diabetes.  Millions of men with type 1 diabetes, which is the form of the condition you are born with, or the most common, type 2 diabetes, which develops primarily due to poor diet, are dealing with symptoms of erectile dysfunction.  For men with type 2 diabetes and erectile dysfunction, the condition can be controlled with a natural erectile dysfunction cures, and a heart healthy diet.  For men with diabetes, the American Association of Urology recommends using an erectile dysfunction pump for men with diabetes and erectile dysfunction.

Erectile Dysfunction is not the same condition as premature ejaculation.  Men with premature ejaculation are able to achieve an erection sufficient for sexual intercourse, but due to over stimulation of the penis, ejaculate within one to two minutes of beginning intercourse with their partner.  Men with erectile dysfunction, on the other hand,  are unable to achieve hard erections capable of vaginal penetration or are not able to achieve an erection at all.


Prostate cancer isn’t considered a cause of ED on its own, but radiation treatments, hormone therapy, and surgery to remove the entire prostate gland can lead to difficulty in getting or keeping an erection. Sometimes erectile dysfunction related to prostate cancer treatment is only temporary, but many guys experience ongoing difficulties that need to be addressed by other means.
Surprisingly, one of the main causes of erectile dysfunction (ED) or impotence may be in that icy mug of beer you are enjoying right now! A common cause of difficulty with erection is overuse of alcohol. Small amounts of alcohol can help us relax and help remove inhibitions, which can help the sexual mood and actually increase sexual activity. Nevertheless, as the amount of alcohol in the blood increases, the alcohol only serves to depress the brain’s ability to sense sexual stimulation.
Once you have talked to your partner about your issues, you may want to consider taking things one step further with psychosexual therapy. This is a form of therapy in which both you and your partner see a therapist together. The therapist will help you and your partner break out of the cycle of stress and disappointment that has been coloring your sex life and contributing to your ED. Going to a therapist with your partner may also help you work out any relationship issues that have been affecting your sex life so the both of you will be more satisfied.
What happens is that the blood vessels of the penis are rather small, and a small amount of plaque in the penile arteries is going to result in erectile dysfunction. You need more plaque before the person’s actually symptomatic from a heart problem, but they’re linked. And so when anybody, any man has an erectile issue, it’s incumbent upon the physician to make certain that their cardiac status is healthy.

There are many factors that can lead to ED. “Psychological causes of erectile dysfunction in young men can include performance anxiety, guilt about sex in general, guilt about having sex with a particular partner, feelings of anger or resentment towards a partner, or simply finding a partner undesirable,” said Carole Lieberman, MD, a psychiatrist on the clinical faculty of the UCLA Neuropsychiatric Institute in Los Angeles.

Is your erectile dysfunction due to psychological (stress, relationship problems, etc.) or physical factors? Your doctor may ask if you note erections at night or in the early morning. Men have involuntary erections in the early morning and during REM sleep (a stage in the sleep cycle with rapid eye movements). Men with psychogenic erectile dysfunction (erectile dysfunction due to psychological factors such as stress and anxiety rather than physical factors) usually maintain these involuntary erections. Men with physical causes of erectile dysfunction (for example, atherosclerosis, smoking, and diabetes) usually do not have these involuntary erections. Men with psychogenic erectile dysfunction may relate the onset of problems to a "stressor," such as failed relationship. Your doctor may suggest a test to determine if you have erections during sleep, which may suggest that there may be a psychological cause of the erectile dysfunction.
The U.S. FDA (Food and Drug Administration) has a list of 29 OTC products that claim to treat erectile dysfunction. Patients should avoid these because many contain harmful ingredients. Other natural or herbal remedies such as DHEA, L-arginine, ginseng, and yohimbe are supplements that have been used but have not been proven safe and effective according to some researchers. Before using such compounds, individuals should consult their doctor. According to some experts, acupuncture does not effectively treat erectile dysfunction. Other home remedies for reducing ED symptoms include diet changes such as eating blueberries and citrus fruits and drinking red wine.

Fully restoring sexual health with treatment of a medical condition (such as high blood pressure with diet and/or exercise or by controlling diabetes or other chronic diseases) may not be possible. Identification and treatment of these conditions may prevent the progression of ED and affect the success of various ED therapies. Nutritional states, including malnutrition, obesity, and zinc deficiency, may be associated with erectile dysfunction, and dietary changes may prove a sufficient treatment. Masturbation and excessive masturbation are not felt to cause ED, however, if one notes weak erections with masturbation, this may be a sign of ED. Some men who masturbate frequently may have troubles with achieving the same degree of stimulation from their partner, but this is not ED.

Describing the epidemiology of ED in young men requires, first of all, defining what it is meant by youth. While the definition of old age is matter of discussion and a precise threshold does not exist, the most shared definition in Western Countries is age above 65 years (http://www.who.int/healthinfo/survey/ageingdefnolder/en/). Considering that most of the epidemiological studies on general populations aimed at studying health changes with age, enrol men more than 40 years, it seems reasonable to define young age as below 40 years. Epidemiological studies on erectile function, which considered the prevalence of ED according to age bands, consistently find a significant increase with ageing. Advancing age remains one of the most important unmodifiable risk factors for ED (1). Studies on ED mostly involve middle-aged and older men, with younger aged men often overlooked. In a multi-centre worldwide study, involving more than 27,000 men from eight countries, Rosen et al. (2) showed an ED prevalence of 8% among men aged 20–29 years and 11% among those aged 30–39 years. Most of the studies involving younger men and conducting age-stratified analyses have been performed in Europe, where the prevalence of ED in men younger than 40 years ranges between 1% to 10% (3-10). The prevalence reported in these studies is highly variable due to different methodologies used in defining ED, population accrual, acquisition of data and choice of tools for investigating erectile function. A smaller number of studies on this topic have been conducted outside Europe. Both in Australia (11,12) and in America (13-15), the available information suggests a similar range of prevalence of ED among young subjects, with the same extent of variability among studies. According to these data, ED in younger men, although still not extensively studied and largely overlooked by the scientific community, is a quite common condition. In a recent study conducted in a Urology Clinic, it has been observed that one out of four men seeking medical care for ED was younger than 40 years (16). In our Sexual Medicine and Andrology Unit, established in an Endocrinology setting at the University of Florence, medical consultations for younger men are infrequent, with a prevalence of men aged less than 40 years at only 14.1% of more than 3,000 men complaining of ED. However, when considering the new referrals to our Unit during the last 6 years, we can notice a progressive increase in prevalence of men below 40 years seeking medical care for ED (Figure 1). According to these data, ED is becoming a common concern even among young men, and the clinical practitioner in sexual medicine must become aware of how to manage the problem and avoid underestimating a symptom. The identification of ED in a young man may potentially provide a great deal of useful information that can help improve their quality and even length of life.
Patient can inject medications directly into the corpora cavernosa to help attain and maintain erections. Medications such as papaverine hydrochloride, phentolamine, and prostaglandin E1 (alprostadil) can be used alone or in combinations to attain erections. All of these medications are vasodilators and work by increasing blood flow into the penis. Prostaglandin E1 (Caverject, Edex) is easier to obtain; however, it is associated with penile pain in some individuals. The use of combinations of two or three of these medications can decrease the risk of having penile pain.
The medications are extremely effective, which is very good. And the medications are, for the most part, extremely well-tolerated. But there are, like with any medications, a potential downside. The one absolute downside to the use of any of these erection what we call PDE5 medications is if a patient is using a nitroglycerin medication. And nitroglycerins are used for heart disease and for angina, for the most part, although there are some recreational uses of nitrites. And that’s important because your blood vessels will dilate and your blood pressure will drop. And that is an absolute contraindication.
Sexual dysfunction appears to be common among male subjects with alcohol dependence. Seventy-two per cent of the subjects with alcohol dependence complained of one or more problems with sexual functioning. This is similar to what has been reported in earlier studies.[10,16] Multiple co-existing dysfunctions seemed to be the norm in the sample studied. The most common condition reported in our study was premature ejaculation followed closely by low sexual desire and erectile dysfunction.
"The good news is, our study also found that a large proportion of men were naturally overcoming erectile dysfunction issues. The remission rate of those with erectile dysfunction was 29%, which is very high. This shows that many of these factors affecting men are modifiable, offering them an opportunity to do something about their condition," Professor Wittert says.
Look, ED can have many causes. Most of the time, it’s physiological. But there are also lots of psychological reasons why someone may experience ED. Treating ED isn’t all about medication. Dealing with some of these psychological issues can help you battle ED, too. I’m talking about depression, anxiety, loss of desire, sense of inadequacy, guilt, fatigue, anger, relationship dysfunction. Working through these types of psychological challenges can help you achieve the happy, healthy manhood you deserve.

Performance anxiety can be another cause of impotence. If a person wasn’t able to achieve an erection in the past, he may fear he won’t be able to achieve an erection in the future. A person may also find he can’t achieve an erection with a certain partner. Someone with ED related to performance anxiety may be able to have full erections when masturbating or when sleeping, yet he isn’t able to maintain an erection during intercourse.


Tobacco use though, was not found to be a significant determinant of sexual dysfunction. This is contrary to all reported evidence.[19] This finding is most likely to be due to our treatment of tobacco use as a categorical (present / absent) variable in a situation where almost 90% of the sample was using tobacco. Future studies need to use indices of severity to avoid this error.

Obesity and metabolic syndrome can cause changes in blood pressure, body composition, and cholesterol which may lead to ED. Other conditions that may contribute to erectile dysfunction include Parkinson’s, multiple sclerosis, Peyronie’s disease, sleep disorders, alcoholism, and drug abuse. Taking certain medications can also increase your risk for ED.
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.

Sildenafil (Viagra) was the first oral phosphodiesterase type 5 (PDE5) inhibitor approved by the FDA in the United States for the treatment of erectile dysfunction (it is not approved for women). Sildenafil inhibits PDE5, which is an enzyme that destroys cGMP. By inhibiting the destruction of cGMP by PDE5, sildenafil allows cGMP to accumulate. The cGMP in turn prolongs relaxation of the smooth muscle of the corpora cavernosa. Relaxation of the corpora cavernosa smooth muscle allows blood to flow into the penis resulting in increased engorgement of the penis. In short, sildenafil increases blood flow into the penis and decreases blood flow out of the penis.
• Blood Vessels: Diabetes damages blood vessels, especially the smallest blood vessels such as those in the penis. Diabetes can also cause heart disease and other circulatory problems. Proper blood flow is absolutely crucial to achieving erection. “Erection is a hydraulic phenomenon that occurs involuntarily,” says Arturo Rolla, MD, of Harvard University School of Medicine. “Nobody can will an erection!” Anything that limits or impairs blood flow can interfere with the ability to achieve an erection, no matter how strong one’s sexual desire.
