The implant

The implant is:

  • Over 99% effective

What is it?

It is a small flexible rod put under the skin of your upper arm. You can feel it under the skin but you can’t see it. Insertion and removal must only be done by a specially trained doctor.

How does it work?

It works by:

  • stopping ovulation (an egg being released from your ovaries)
  • thickening the mucus at the neck of the womb (uterus) so that it is difficult for sperm to enter the womb
  • thinning the lining of the womb and this prevents a fertilised egg from settling (implanting) in the womb

It is important that you talk to a doctor who will assess what contraceptive option is best for you.


  • It does not interrupt sex.
  • It works for up to 3 years.
  • It may reduce painful periods.


  • Its effectiveness may be reduced by taking certain medications.
  • It does not protect against sexually transmitted infections.
