How does the contraceptive implant work?
The contraceptive implant can stop you getting pregnant in two ways:
- By preventing an ovum (egg) from developing in the ovaries
- By thickening 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. The contraceptive implant also makes the lining of your womb thinner and less ready to accept a fertilised egg.
