It is a small flexible tube under the skin of the arm and canít be seen. It releases the hormone progestogen that stops ovulation, thickens cervical mucus to prevent sperm meeting an egg and thins the lining of the womb to prevent an implanting. Like the injection the hormones are released slowly into your body for up to three years so you donít have to remember to take a pill. Unlike the injection it can be removed at any time and when it is removed fertility levels return to normal.

Over 99% effective, less than 1 woman in 100 will get pregnant in a year. The implant will not protect you from STIs.
