The progestin-only hormone implant (such as Implanon)
The progestin-only hormone implant releases hormones that prevent pregnancy for 3 years. It must be inserted and removed by a trained health professional. The actual implant is about the size of a matchstick and is inserted under the skin on the inside of the upper arm.
