What is erectile dysfunction?
ED is when a man has difficulty getting or maintaining an erection long enough for sex. It happens when not enough blood flows to the penis.
ED isn’t the same for all men. Some men aren’t able to get an erection at all. Others can get one, but it’s not hard enough for sex. And others get a hard erection but lose it before or during sex.
ED is a medical condition. So in most cases, erections will not improve without treatment.
Many men avoid discussing ED. In fact, they often wait more than a year before talking to their doctor. But once they’ve had the discussion, most guys say they feel relieved to have finally done something about it.
Why erectile dysfunction (ED) happens
ED can be caused by things like stress or fatigue. But a lot of times, ED is not something that you can control. That’s because it’s often due to a physical problem that affects your blood flow.
Usually when a man is sexually aroused:
- The brain sends an impulse telling the arteries in the penis to widen.
- As a result, more blood flows to the penis.
- When this happens, the penis expands and hardens. This causes an erection.
When a man has ED, the nerves or blood vessels in the penis don’t work properly. This prevents blood from flowing to the penis. And that can prevent an erection.
Causes of ED
ED is often caused by other health issues that can affect the flow of blood to the penis. No matter what the cause, treatment is usually effective.
Find out why these issues can affect blood flow:
High blood pressure
High blood pressure makes the heart work harder. This puts strain on the blood vessels, which then harden and narrow. This can prevent blood from getting to the penis. And that makes it more difficult to get or keep an erection.
More than 65% of men with high blood pressure also have ED.
High blood cholesterol can clog your arteries. This can slow blood flow to the penis. As a result, it can affect the quality of your erections.
Having high cholesterol raises your risk of ED by 80%.
Heart disease also is known as coronary artery disease.
For a person with heart disease, blood does not flow as easily throughout the body as it should. That’s because the arteries are clogged or narrowed. This may slow blood from getting to the penis and prevent a firm erection.
Diabetes is a condition where there is too much sugar, or glucose, in the blood. Over time, high blood sugar levels can damage nerves and blood vessels like those that produce erections. When this occurs, diabetes often leads to ED.
Up to 85% of men with diabetes have some erection difficulty.
The prostate is a small gland near your bladder. It is next to the nerves that are needed for erections. That’s why certain treatments for prostate problems can lead to ED.
For men with depression, the cause of ED may be psychological, physical, or both. ED can lower self-esteem and strain your relationship with your partner. And certain medicines that treat depression can cause ED.
An injury to the spine can affect almost every function in the body. For men with spinal injuries, ED is the most common sexual problem.
There are many medicines that can cause ED. The most common are:
- Certain medicines that lower blood pressure
- Some heart medicines
- Some cancer medicines
- Certain medicines for depression
