What are erection problems?

Most men have trouble getting an erection at some time in their life. But some men can't get an erection at all. And some men have trouble keeping an erection long enough to have sex that is satisfying. But there are treatments that can help. If you have erection problems, talk to your doctor about finding the right treatment for you.

Doctors call this condition erectile dysfunction. The word dysfunction means that something doesn't work properly. This problem used to be called impotence. But erectile dysfunction is a more accurate name.

If you have erection problems, ask your doctor about treatments that could help you.

If you have erection problems, you may feel embarrassed or ashamed. These feelings stop many men from seeing their doctor. But more than half the men in the United States between the ages of 40 and 70 have some problems having erections.

Key points about erection problems
  • If you have erection problems, you have trouble getting an erection or keeping an erection long enough to have sex that is satisfying.

    diabetes
    Diabetes is a condition that causes too much sugar to circulate in your blood. It happens when your body stops making a hormone called insulin (type 1 diabetes) or when insulin stops working (type 2 diabetes).

What happens when you get an erection
To understand erection problems and how they can be treated, it's useful to know something about how your penis works and how erections happen.

Your penis has spongy columns that fill with blood when you get an erection.

How your penis works
Your penis is mainly made up of spongy tissue and blood vessels.

The tube that carries urine and
 
 
 
 
 
semen
Semen is the whitish fluid that is released through the penis during orgasm. Semen is made up of millions of tiny sperm floating in fluid. Sperm are the part of the semen that can join with a woman's eggs to make her pregnant. Sperm are made in the testicles, and travel through tubes (called the vas deferens) to get to the penis. Along the way, the sperm are joined by fluid that is released from the prostate and seminal vesicles. This fluid helps the sperm to travel and provides them with nutrients.
 
 
 
 
 
semen runs through the middle. It's called the urethra.

The tip of your penis is called the glans. The rest of your penis is called the shaft.

Two columns of spongy tissue run through the upper part of your penis. When you have an erection, the spongy columns fill up with blood and get stiff.

How you get an erection
There are lots of spaces inside the spongy columns in your penis.

This picture shows a cross section of a penis.

When your penis is limp, these spaces are empty. When you have an erection, the spaces are full of blood. This makes the columns firm.

Blood vessels called
 
 
 
 
 
arteries
Arteries are the blood vessels that take blood that is rich in oxygen and food away from your heart. The arteries carry this blood to all the tissues in your body.
 
 
 
 
 
arteries supply the extra blood that you need to get an erection.

There are also nerves in your penis. They send messages around your penis to help erections happen.

Other nerves bring messages from your brain about what you're thinking and feeling about sex.

Erections happen when nerves in your penis release certain chemicals that change the way blood flows into your penis.

See More about how erections happen to learn more.

Erection problems: what goes wrong
You may have problems getting an erection or keeping an erection long enough to enjoy sex. There are several possible causes.

Emotional reasons
Stress or unhappiness can cause erection problems. Your emotions can stop you from having an erection or make it disappear too soon.

If you have erection problems, you may feel anxious or guilty. And if you're worried about whether you'll get an erection, this worry can make it more difficult to get one.

If you think your erection problems may be caused by stress or unhappiness, it can help to talk to a
 
 
 
 
 
psychotherapist
A psychotherapist is a health professional who treats mental disorders by talking with their patients, rather than by prescribing medicines. There are many types of psychotherapy, including cognitive behavioral therapy and interpersonal therapy.
 
 
 
 
 
psychosexual therapist or
 
 
 
 
 
counselor
A counselor is a professional who is trained to help people, usually with the emotional part of their illness. Counselors talk to people about their illness. They also suggest ways that people can make changes for the better.

Damaged nerves
You may get erection problems if your nerves can't tell your penis to make erections happen. This may happen if you have:

  •  
     
     
     
     
    diabetes
    Diabetes is a condition that causes too much sugar to circulate in your blood. It happens when your body stops making a hormone called insulin (type 1 diabetes) or when insulin stops working (type 2 diabetes).
     
     
     
     
     
    Diabetes (an illness that can damage the nerves in your penis and in other parts of your body)
  •  
     
     
     
     
    multiple sclerosis
    Multiple sclerosis, or MS for short, is a disease that involves damage to the walls of nerves. No one knows for sure what causes it. If you have multiple sclerosis, you may lose feeling in certain parts of your body. You may also have trouble with your vision or controlling your movements.

  • An injury to your groin area
  • Surgery in your groin area, which can damage the nerves in your penis
  •  
     
     
     
     
    radiation therapy
    This treatment uses high-energy X-rays to kill cancer cells. It's most often used for tumors that are hard to treat with surgery alone. You won't feel any pain during this treatment, but you may get some side effects afterward.
     
     
     
     
     
    Radiation therapy to your pelvis to treat prostate cancer.
Damaged blood vessels
If you have a condition called
 
 
 
 
 
atherosclerosis
Atherosclerosis is also called "hardening of the arteries." It happens when fatty material attaches to the inner wall of the arteries. Over time, cholesterol, fats and other blood components stick to the same area and the artery wall becomes thick and narrow, making it progressively more difficult for blood to flow through the affected vessels.
 
 
 
 
 
atherosclerosis, where your arteries become clogged, it can stop blood from flowing into your penis. This can cause erection problems.

And if blood isn't kept in your penis but starts leaking out through your veins, then your erection may not be firm or last long. This may happen naturally as you get older. It can also happen if you have an illness called
 
 
 
 
 
diabetes
Diabetes is a condition that causes too much sugar to circulate in your blood. It happens when your body stops making a hormone called insulin (type 1 diabetes) or when insulin stops working (type 2 diabetes).
 
 
 
 
 
diabetes.

A condition called Peyronie's disease changes the way blood flows through your penis.

Levels of hormones
If you don't have enough of a
 
 
 
 
 
hormones
Hormones are chemicals that are made in certain parts of the body. They travel through the bloodstream and have an effect on other parts of the body. For example, the female sex hormone estrogen is made in a woman's ovaries. Estrogen has many different effects on a woman's body. It makes the breasts grow at puberty and helps control periods. It is also needed to get pregnant.
 
 
 
 
 
hormone called
 
 
 
 
 
testosterone
Testosterone is a sex hormone. When boys go through puberty, testosterone causes the development of male characteristics like a deep voice and a muscular body. Testosterone is also known to affect men's sex drive and mood. Although testosterone is thought of as a 'male hormone', women also make testosterone (although they make much less of it then men).
 
 
 
 
 
testosterone, you may have erection problems. Testosterone is the hormone that gives you your sex drive (libido).

Having too much of a hormone called
 
 
 
 
 
prolactin
Prolactin is a hormone that your body makes. Its main job is to prepare a woman's breasts for breastfeeding after she's had a baby. If men have too much prolactin in their blood, it can lower their sex drive and make it difficult for them to father a child.
 
 
 
 
 
prolactin can also give you erection problems.

If you have one of these problems, you may need to see a doctor who specializes in hormones.

Why me?
There may be some things about you or your health that make it more likely that you'll have problems getting erections.

For example, if you're taking drugs to treat another medical condition, the drugs may cause erection problems.

How your doctor can help
Most men who have an erection problem don't talk to their doctor about it.

5 But there are at least two good reasons for doing so.

  • You don't need to suffer. There are treatments that can help you have satisfying sex again. These treatments will help you feel better about yourself and your relationship. If you're feeling depressed, you're more likely to have erection problems. Sorting out these problems can make you feel less depressed.
