Intrauterine devices and contraceptive implants, also called long-acting reversible contraceptives (LARC), are the most effective reversible contraceptive methods. The major advantage of LARC compared with other reversible contraceptive methods is that they do not require ongoing effort on the part of the patient for long-term and effective use. In addition, after the device is removed, the return of fertility is rapid (1, 2). The purpose of this Practice Bulletin is to provide information for appropriate patient selection and evidence-based recommendations for LARC initiation and management. The management of clinical challenges associated with LARC use is beyond the scope of this document and is addressed in Committee Opinion No. 672, Clinical Challenges of Long-Acting Reversible Contraceptive Methods (3).
宫内节育器和避孕植入物，也称为长效可逆避孕方法（LARC），是最有效的可逆避孕方法。与其他可逆避孕方法相比，LARC 的主要优势在于，长期有效使用时无需患者持续投入精力。此外，取出装置后，生育力迅速恢复（1,2）。本实践公告的目的是为 LARC 的启动和管理提供适当的患者选择和基于证据的建议信息。与 LARC 使用相关的临床挑战的管理不在本文档的范围内，详见委员会意见 No.672《长效可逆避孕方法的临床挑战》（3）。
