Erectile dysfunction: what it is and why it happens

Erectile dysfunction (ED) means having trouble getting or keeping an erection firm enough for sex. Research suggests 30 to 50 million men in the United States have it. It becomes more common with age, but it is not something you just have to live with.

ED is common and treatable. Millions of men have it, and most find an option that works.

Signs of ED

  • Trouble getting an erection some or most of the time
  • Trouble keeping an erection long enough for sex
  • Erections that are less firm than they used to be
  • Less interest in sex, which can happen alongside ED

Having trouble once in a while is normal. If it happens often, or for more than a few weeks, it’s worth talking to a provider.

Common causes

An erection needs healthy blood vessels, nerves, hormones, and a clear head. A problem with any of these can cause ED, and many men have more than one cause.

  • Blood vessel problems: heart disease, high blood pressure, high cholesterol, smoking
  • Diabetes: high blood sugar can damage blood vessels and nerves
  • Hormones: low testosterone or thyroid problems
  • Medications: some blood pressure drugs, antidepressants, and others
  • Surgery or injury: including prostate cancer treatment
  • Stress, anxiety, or depression
  • Alcohol, drug use, and poor sleep

Never stop a prescribed medication on your own. If you think a medicine is affecting erections, ask your doctor about alternatives.

Common questions

At what age does ED usually start?

ED can happen at any adult age, but it becomes more common as men get older. Federal research data show about 40% of men are affected at age 40, and about 70% report ED by age 70.

Is ED reversible?

Often it can improve, especially when the cause is found and treated, such as high blood pressure, high blood sugar, smoking, heavy drinking, poor sleep, or a medication side effect. Even when it doesn’t go away completely, most men find a treatment that works for them.

Can stress or anxiety cause ED?

Yes. Stress, anxiety, and depression can cause ED or make it worse, and they often show up alongside physical causes. Talking with a provider or counselor can help, and it works well alongside medical treatment.

Is it normal to have trouble getting an erection once in a while?

Yes, having trouble once in a while is normal and usually not a sign of a health problem. If it happens often, or keeps happening for more than a few weeks, it’s worth talking to a provider.

Can my medications cause ED?

Some medicines can, including certain blood pressure drugs and antidepressants. Never stop a prescribed medicine on your own; ask your doctor whether a different option might be easier on erections.
