Implant (Nexplanon): Basic Info
The implant (Nexplanon and its generic versions) is a small rod, about the size of a matchstick, that's inserted under the skin of your upper arm (after you get numbing medication!). Once it's inserted, it's not visible in most cases.
The implant slowly releases a single hormone, progestin, that prevents pregnancy primarily by thickening cervical mucus, making it harder for sperm and egg to meet. It's FDA-approved to prevent pregnancy for up to three years, but research shows it's effective for up to five years. You can always get it removed sooner if you want to.
