The contraceptive implant is a flexible rod about the size of a matchstick. It’s inserted just under the skin of your upper arm and slowly releases the synthetic hormone progestogen. It can be left in place for up to 3 years. It’s a very effective contraceptive, and a good option if you want contraception that you don’t have to think about every day.
