The human costs of unintended pregnancy-abortion and parenting under difficult circumstances-are high. For this reason, all physicians who treat female patients should be knowledgeable about the basics of contraception-both its practical uses and its public health impact. This knowledge will make physicians, including internists, better able to counsel and provide contraceptives for individual patients and to advocate for availability and access. This article discusses the problem and determinants of unintended pregnancy and reviews contraceptive methods.
意外怀孕（流产以及在困难情况下养育子女）给人类带来的代价高昂。因此，所有诊治女性患者的医生都应了解避孕的基本知识——包括其实际用途及其对公共卫生的影响。这些知识将使包括内科医生在内的医生更有能力为个体患者提供咨询并提供避孕措施，以及倡导避孕措施的可获得性和可及性。本文讨论了意外怀孕的问题和决定因素，并对避孕方法进行了综述。
