There are many possible causes such as:

  • Being very overweight

  • Having diabetes

  • High blood pressure or high cholesterol

  • Depression (if you think you may be depressed, see your doctor)

  • Smoking cigarettes

  • Medicines (talk to your doctor or pharmacist about whether this could relate to your medicines, do not stop taking your regular medicine without their advice)

  • Use of recreational (street) drugs

  • Relationship difficulties (you may need relationship counselling)

  • Being tired or stressed

  • Drinking too much alcohol

  • Performance Anxiety

Erectile dysfunction (ED) can sometimes be caused by an important health problem, all men with erection problems should inform their doctor that it is occurring. Erection problems can also occur from a build-up of fatty deposits in the blood vessels, the same problem that causes heart trouble.
