The contraceptive implant (nexplanon) is a small flexible plastic rod that's placed under the skin in your upper arm by a doctor or nurse. A local anaesthetic is used to numb the area. The small wound made in your arm is closed with a dressing and doesn't need stitches.
It releases the hormone progestogen into your bloodstream to prevent pregnancy and lasts for three years.
The implant steadily releases the hormone progestogen into your bloodstream, which prevents the release of an egg each month (ovulation). It also thickens the cervical mucus, which makes it more difficult for sperm to move through the cervix and thins the lining of the womb so a fertilised egg is less likely to implant itself.
The implant is more than 99% effective.
It can be useful for women who can't use contraception that contains oestrogen. It's also very useful for women who find it difficult to remember to take a pill at the same time every day.
