Why can’t I get and keep an erection?

At some stage in their life, most men have an occasional episode of being unable to get and keep an erection. It’s usually nothing to worry about and is often a result of:

  • stress
  • tiredness
  • anxiety
  • drinking too much alcohol

However, if you frequently have erection problems, you could have erectile dysfunction (ED), also known as impotence.

What is erectile dysfunction (ED)?

ED is a regular inability to get and keep an erection. It may only happen in some situations; for example, you may be able to get an erection when masturbating, but can’t keep an erection when you’re with your partner. It’s important to remember that erectile dysfunction is a symptom and not a disease, therefore it's important to identify what may be causing it.

Who gets erectile dysfunction?

ED can affect men at any age, but is more common as men get older. It’s estimated that half of all men aged between 40 and 70 have some degree of ED.

What causes erectile dysfunction?

ED can also be a side effect of some medication.

When to get medical advice

If you think you have symptoms of ED, it’s important to see your GP or go to a genitourinary medicine (GUM) clinic, so they can assess whether you need any treatment. If you find talking about it embarrassing, remember that doctors are used to dealing with problems like this.
