Worldwide, 40% of all pregnancies are unintended. Widespread, over-the-counter availability of oral emergency contraception (EC) has not reduced unintended pregnancy rates. The EC visit presents an opportunity to initiate a highly effective method of contraception in a population at high risk of unintended pregnancy who are actively seeking to avoid pregnancy. The copper intrauterine device (IUD), the most effective method of EC, continues to provide contraception as effective as sterilization for up to 12 years, and it should be offered as the first-line method of EC wherever possible. Increased demand for and supply of the copper IUD for EC may have an important role in reducing rates of unintended pregnancy. The EC visit should include access to the copper IUD as optimal care but should ideally include access to all highly effective methods of contraception.
在全球范围内，40%的妊娠都是意外妊娠。广泛、非处方的口服紧急避孕（EC）的供应并没有降低意外妊娠率。EC 就诊为在高风险意外妊娠人群中提供一种高度有效的避孕方法提供了机会，这些人群正在积极寻求避孕。铜宫内节育器（IUD）是最有效的 EC 方法，在长达 12 年内提供的避孕效果与绝育一样有效，因此应尽可能将其作为 EC 的一线方法提供。增加 EC 用铜 IUD 的需求和供应可能在降低意外妊娠率方面发挥重要作用。EC 就诊应包括获得铜 IUD 的机会，这是最佳护理，但理想情况下还应包括获得所有高度有效的避孕方法。
