Avoiding controversy in international provision of subdermal contraceptive implants.

International agencies work with host country governments to estimate contraceptive needs and to procure commodities at affordable public-sector prices. Depending on the agency and the registration status of the commodity in the given country, three subdermal contraceptive implants are options for purchase: Jadelle® is a two-rod levonorgestrel implant approved for 5 years of continuous use (Bayer HealthCare, Berlin, Germany), Implanon® (Merck & Co., Inc., Whitehouse Station, NJ, USA) is a one-rod etonogestrel implant (approved for 3 years) and Sino-implant (II) (Shanghai Dahua Pharmaceutical Co., Ltd., China) is another two-rod levonorgestrel implant (approved for 4 years).
