重点放在宫内避孕药（IUC），避孕植入剂，和紧急避孕药，我们回顾了最近的进展，避孕药的发展，并讨论了政策的进展，以提高获得最有效的方法。我们报告在实践中转向常规提供宫内节育器和植入物的年轻和未经产的妇女，促使部分直径减小的插入管的曼月乐IUC和一个较小的IUC称为Skyla的发展。此外，我们描述了新的SCu300A子宫内球和一种名为Nesterion的植入物的开发，该植入物配有预加载的插入器。我们还讨论了醋酸乌利司他与左炔诺孕酮用于紧急避孕的疗效，特别是对于体重超过75公斤的妇女。最后，鉴于越来越多的兴趣提供宫内节育器和植入物的妇女在产后和流产后的时期，我们认为这种变化的理由在实践中，并审查迄今为止在美国取得的进展。
Focusing on intrauterine contraceptives (IUC), contraceptive implants, and emergency contraceptives, we review recent advances in contraceptive development and discuss progress in policies to improve access to the most effective methods. We report on the shift in practice towards routinely providing IUCs and implants to young and nulliparous women, prompted in part by the reduced diameter of the insertion tube for the Mirena IUC and the development of a smaller IUC called Skyla. Additionally, we describe the new SCu300A intrauterine ball and the development of an implant called Nexplanon, which comes with a preloaded inserter. We also discuss the efficacy of ulipristal acetate versus levonorgestrel for emergency contraception, especially for women who weigh more than 75 kg. Finally, in light of the increasing interest in providing IUCs and implants to women in the immediate postpartum and post-abortion periods, we consider the rationale for this change in practice and review the progress that has been made so far in the United States.
