Contraception: Implants

The implant is a small, bendy tube that is put under the skin in your upper arm. In the UK the only one available, currently, is called Implanon.

Where can I get it?
The implant is inserted into your arm using an injection. This is usually done by your GP but some family planning clinics can do it too. You're given a local anaesthetic and putting it in is quick and painless, although you could get a slight bruise from the injection. You can feel the implant, but not see it.
How does it work?
It lasts for up to three years, although it can be taken out sooner if you want. Whereas the injection gives you a high dose of progestogen, which decreases over 8-12 weeks, the implant releases a steady stream of the hormone into your blood every day. This thickens the cervix so it's harder for sperm to get through, makes the womb lining thinner and stops an egg being produced.
How effective is it?
It's over 99% effective. Being obese can stop it from being as effective, so speak to your doctor if you're worried.
What are the good points about it?
Once it's in, that's it for three years. No worrying about booking repeat appointments or taking pills. Your normal level of fertility returns straight away, after it's removed. You can breastfeed with the implant in too.
What are the bad points about it?
They can cause headaches, acne and weight gain and your periods are likely to change. You might even notice a change in sex drive too. Your doctor or clinic will need to order the implants in so you'll need to talk to them, in advance, if you want one. The doctor will also need to remove it too. They don't protect you from sexually-transmitted infections. You will need to use condoms during sex for this.
