The implant

The implant is:

  • 99.9% effective

What is it?

It is a small flexible rod which is placed just under the skin on the inside of your upper arm. It can be felt under the skin but you can’t see it.

How does it work?

The rod slowly releases the artificial female hormone progestogen known as etonogestrel. This stops ovulation (an egg being released). It also thickens the mucus at the neck of the womb. This makes it difficult for sperm to enter the womb. It also thins the lining of the womb.

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