This article describes the first use of ultrasound in locating in vivo NORPLANT® subdermal contraceptive implants. Providing low dose, continuous contraception for women, the NORPLANT® system utilizes Silastic tubing filled with levonorgestrel. The progestin‐filled tubing is not radiopaque. Anticipating the large scale use of NORPLANT® subdermal implants, the potential, but rare problem of difficult localization of an implant is recognized. The feasibility of using ultrasound for the painless and safe localization of NORPLANT® rods and capsules is demonstrated.
