What Are Implants? Progestin-filled rods (each about the size of a match stick) that are inserted under the skin • Jadelle: 2-rod system, effective for 5 years • Sino-implant (II): 2-rod system, effective for 4 years (possibly 5) • Implanon: 1-rod system, effective for 3 years • Norplant: 6-capsule system, effective for 5 years (possibly 7); no longer manufactured but some women are still using it
Key Points for Providers and Clients What it is: – Small tubes placed under the skin of inner, upper arm. – Hormones from the tubes blocks sperm from reaching egg and prevents release of egg.
