Erectile dysfunction

Also called Impotence, Erection problems, or ED

Erectile dysfunction is when you cannot get or keep an erection firm enough for sex. It is very common, especially over the age of 40, and occasional problems are normal. When it happens often, it can be caused by physical problems, such as narrowed blood vessels, diabetes or hormone problems, or by stress, anxiety and relationship issues.

What it is

Because it can be an early sign of heart disease or diabetes, it is worth getting checked.

Lifestyle changes, treating the cause, medicines such as sildenafil, and other treatments help most men. Counselling can help when psychological factors are involved.

Common signs

  • Difficulty getting an erection
  • Difficulty keeping an erection during sex
  • Reduced interest in sex

How it is usually diagnosed

  • A conversation about symptoms, medicines and lifestyle
  • Blood pressure check
  • Blood tests for diabetes, cholesterol and hormones

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Blood sugar, cholesterol and testosterone results
  • Blood pressure readings
  • A list of medicines

Questions to ask your doctor

  • Could this be linked to my heart or blood sugar?
  • Could any of my medicines be causing it?
  • Which treatment is safe for me?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • An erection lasting more than 4 hours: go to an emergency department
  • Chest pain during sex: call 112
