How does Nexplanon (etonogestrel) work?

The Nexplanon contraceptive implant can stop you getting pregnant in one of two ways:

  1. The contraceptive implant prevents eggs from ripening in the ovaries
  2. The contraceptive implant thickens the mucus at the entry to your womb (the cervix). This makes it difficult for sperm to penetrate and reach an egg to fertilise it. It also makes the lining of your womb thinner and less ready to accept a fertilised egg.
The Talk Choice website is a national campaign aimed at the general public that gives information on available methods of contraception.
