"We used to think that ED in young men was 90 percent psychological, but we now know that most cases are caused by a combination of risk factors. Erectile function depends on hormones, blood supply, nerve function, and psychological health,” said Run Wang, MD, professor of urology at The University of Texas Health Science Center in Houston and director of sexual medicine at MD Anderson Cancer Center.

There are, as you listen to all of the advertisements, if your erection lasts for more than four hours, there are very, very unusual cases where that can happen. There are very rare cases of visual problems. There are even rarer cases of hearing problems. But with every medication, there always a potential downside. But the absolute contraindication is an unstable medical condition, an unstable cardiovascular condition, being on nitrates.


All three of these involve specific bodily systems including the hormones, muscles, blood vessels, nervous system, and emotions. If any of these systems become compromised, it can cause ED. In the case of anxiety and stress, these things can affect the brain’s ability to send the necessary signals to trigger the desired physical response – an erection. Stress and anxiety can also contribute to an ongoing cycle of ED, as mentioned earlier.

Cultivating and maintaining a healthy relationship is not easy. It takes time to truly get to know someone and to trust them. If you and your partner are experiencing trouble with your relationship, it could very well bleed over into your sex life. It could also be the case that your erectile dysfunction is creating problems in the relationship – it is another example of the cycle of ED that can affect many different aspects of your life. Communication is the first step in resolving this particular cause for psychological ED but it is also one of the most difficult steps to take.
Vacuum devices for ED, also called pumps, offer an alternative to medication. The penis is placed inside a cylinder. A pump draws air out of the cylinder, creating a partial vacuum around the penis. This causes it to fill with blood, leading to an erection. An elastic band worn around the base of the penis maintains the erection during intercourse.
In regard to circulation, alcohol causes the blood vessels to dilate, which influences the way the blood moves in and out of the penis. A good blood flow regulates the relaxation and contraction of the penis, so it can get and maintain an erection. Without it, no matter how much you may want it to happen differently, your penis will simply remain flaccid.
Excess alcohol causes erectile dysfunction in a variety of ways. Have one too many, and it decreases the production of NO in your penis, decreasing blood flow. It can even prevent the prescription pills from working. A little alcohol may get you aroused, but a lot actually blunts desire in your brain and can make it hard to reach climax as well. Over time excess alcohol damages the nerves to the penis that trigger an erection, and eventually, when the liver gets damaged, testosterone levels plummet. If you drink, practice moderation.
PDE 5 inhibitors are broken down primarily by enzyme, cytochrome P450enzyme CYP3A4. Medications that decrease or increase the activity of CYP3A4 may affect levels and effectiveness of PDE 5 inhibitors. Such drugs include medications for the treatment of HIV (protease inhibitors) and the antifungal medications ketoconazole and itraconazole. Thus caution is recommended.
Erectile dysfunction in older men. Because erections primarily involve the blood vessels, it is not surprising that the most common causes in older men are conditions that block blood flow to the penis, such as atherosclerosis or diabetes. Another vascular cause may be a faulty vein, which lets blood drain too quickly from the penis. Other physical disorders, as well as hormonal imbalances and certain operations, may also result in erectile dysfunction.
Having learned a great deal more about erectile dysfunction including its risk factors and causes, you should be equipped to assess your own erectile function. If you have experienced erectile issues or you have some of the risk factors mentioned above, it may be worth making a trip to your doctor’s office. If you choose to seek help, give your doctor as much information as you can about your symptoms including their frequency and severity as well as the onset. With your doctor’s help, you can determine the best course of treatment to restore sexual function.

"One of the reasons erectile dysfunction increases with age is that the diseases that lead to it also increase with age," notes Dr. Feloney. Evaluating the causes of erectile dysfunction starts with your doctor taking a good health history and giving you a physical exam. Common medical issues that can lead to erectile dysfunction include diabetes, high blood pressure, hardening of the arteries, low testosterone, and neurological disease. Talk to your doctor about better managing these health conditions.
Rates of erectile dysfunction have significantly increased over the last 15 years, especially in men younger than 40. In 2002, a review of 23 studies from Europe, the United States, Asia and Australia found that the rate of erectile dysfunction in that age group was two per cent. More recent studies suggest that erectile dysfunction is becoming more prevalent in younger men, with as many as 15 per cent of men in that age group battling it.
An erection involves the brain, nerves, hormones, muscles, and circulatory system. These systems work together to fill the erectile tissue in the penis with blood. A man with erectile dysfunction (ED) has trouble getting or maintaining an erection for sexual intercourse. Some men with ED are completely unable to get an erection. Others have trouble maintaining an erection for more than a short time.
Psychological Causes of ED – Between 10% and 20% of ED cases have a psychological cause. Because arousal starts in the brain, psychological issues can be a significant contributing factor to erectile dysfunction. Mental health conditions like depression or anxiety can negatively impact your libido, making it more difficult for you to become aroused.
It would be convenient if a fairy dickmother flew from the sky and told you this would be the drink that renders you flaccid, but when it comes to figuring out your limit, you’re on your own. There’s no hard and fast rule as to how much will actually affect you, either; Dr Mills notes that some men may be able to drink a lot and get erections, as everybody’s threshold is different.
If you have unstable heart disease of any kind, heart failure or unstable, what we call angina, contraindication to using the medications. All right? So if you’re in an unstable medical state, these medications are not a good idea. Now, there are relative issues. If you may be taking a blood pressure medicine or a medicine for your prostate which dilates your blood vessel a little bit– you know, the typical ones are what we call the alpha blockers– you may have an additive effect from the medication. But for the most part, the medicines are incredibly safe.
If you answer “yes” to any of these questions, your ED may well have a psychological link. To confirm this diagnosis, you may want to complete a full psychological evaluation. This is particularly important if you suspect that your ED has something to do with a mental health issue like anxiety or depression that might require additional treatment, either medical or psychosocial.

There was a significant reduction in the frequency of sexual intercourse per week over the last five years having decreased from a mean of 4.6 (± 2.6) times per week to 2.2 (± 2.2) times per week currently. Forty-eight per cent of the sample had more than one sexual dysfunction. Of the 24 subjects with only one complaint, the most frequent complaint was that of premature ejaculation in 18 subjects.
To avoid the dreaded whiskey d---, you don’t necessarily have to stop drinking alcohol. Just drink in moderation. The National Institute on Alcohol Abuse and Alcoholism defines moderate drinking as no more than two drinks a day for men, and one drink a day for women. The liver can only process 1 ounce of liquor or one standard drink in one hour. Consuming more than this will lead the system to become saturated, where extra alcohol will increase in the blood and body tissues, until the liver is ready to metabolize it again. Until then, high blood alcohol concentration will last for several hours and affect you physiologically.
With coronary artery disease, a buildup of plaque inside the arteries can limit the amount of blood that’s able to flow through them. If the flow of oxygen-rich blood to your heart muscle is reduced or blocked by this hardening of the arteries, the result can be angina (chest pain) or a heart attack.17 Because the arteries that supply blood to the penis are much smaller than the ones that feed the heart, the problem may show up earlier as having difficulty getting an erection.18
A 2009 study published in The Journal of Sexual Medicine found less volume of liquid in the body in conjunction with a depressed nervous system, led to a struggle with sexual performance. This is because alcohol can dehydrate the body, decreasing blood volume while increasing the hormone associated with erectile dysfunction — angiotensin. The body is able to work at optimal capacity by staying hydrated, since major biological activities and functions utilize water molecules.
This form of therapy has a response rate of well over 70%. The sympathetic nervous system normally maintains the penis in a flaccid or non-erect state. All of the vasoactive drugs, when injected into the corpora cavernosae, inhibit or override sympathetic inhibition to encourage relaxation of the smooth muscle trabeculae. The rush of blood engorges the penile corpora cavernosae sinusoidal spaces and creates an erection.

Research has shown that the same eating patterns that can cause heart attacks due to restricted blood flow in the coronary arteries can also impede blood flow to and within the penis. The blood flow is needed for the penis to become erect. Diets that include very few fruits and vegetables along with lots of fatty, fried, and processed foods can contribute to decreased blood circulation throughout the body.
Inflatable prostheses are complex mechanical devices that imitate the natural process of erection. Parts are inserted surgically into the penis and scrotum, and activated by squeezing. When erection is no longer desired, a valve on the pump is pressed, and the penis becomes flaccid. Self-contained single-unit prostheses are similar to the inflatable types, but more compact. The entire device is implanted into the penis. When erection is desired, the unit is activated by either squeezing or bending, depending on which of the two types of self-contained prostheses is used.
