Worldwide, more than one fourth of all pregnancies are unintended. Emergency contraceptives are used after sexual intercourse to reduce the risk of pregnancy and have the potential to significantly decrease the incidence of unplanned, unwanted, and mistimed pregnancy. But despite its safety and efficacy, emergency contraception (EC) continues to spark political controversy worldwide. In this edited volume, authors explore how EC has been received, interpreted, and politicized. Through the in-depth examination of the journey of EC in 16 individual countries, chapters in this book reveal the ways that a global reproductive health technology is inflected with local cultural meaning and simultaneously influenced by transcendent challenges that condition the introduction of a new technology.
