Implant

How effective?

Over 99% effective. Less than one woman in 100 will get pregnant in a year.

How it works

Flexible tube inserted under the skin of the upper arm. Releases progestogen. It stops ovulation, thickens cervical mucus to prevent fertilisation and thins the lining of the uterus to prevent an egg implanting.

Advantages

Works for three years but can be taken out at any time. You don’t have to think about contraception for as long as the implant works. When the implant is removed the normal level of fertility will return.

Disadvantages

Periods are often irregular, much longer or stop for at least the first year. Some women may gain weight. Other possible side effects include headaches, spotty skin, mood changes, breast tenderness and changes in libido.

Comments

Put in using a local anaesthetic and no stitches are needed. Tenderness, bruising and some swelling may occur at the site .The implant may be felt with the fingers but it is not visible.
