The implant is a form of contraception for women, to prevent pregnancy. It contains progestogen, a hormone similar to one produced by your ovaries. It does not contain oestrogen.
- The implant is made up of two small rods (each about the size of a matchstick) that contain progestogen. The rods are placed under your skin, on the inside of your arm (you can feel the rods under your skin).
- The implant works by slowly releasing progestogen into your bloodstream. Progestogen thickens the mucus in the cervix so sperm can’t travel through it and may also stop the ovaries from releasing an egg each month. In this way it prevents pregnancy.
- The implant is referred to as a long-acting form of contraception, which means that once you have had it fitted, you don't have to remember about it every day or every time you have sex – until the next implant is due. The implant lasts for up to 5 years.
- Its effect is reversible which means that your natural fertility returns to normal when the rod is removed.
