This special issue of EASTS examines reproductive technoscience, gender, and the formation of East Asian modernities across the twentieth and into the twenty-first century. We begin our introduction with a brief overview of social science scholarship to date on reproductive topics. We then turn to emergent trends: going to and coming from beyond the West, complicating the issues, and intensive localizing and comparative research. Next, we discuss themes that cut across considerations of gender, reproductive technologies, and related issues in East Asia: issues of imperialisms and colonialisms as roots and contexts, postcolonial and nationalist forms of embeddedness, feminist theories of gender and transnationalism, and relations of gender and reproductive technologies to biological citizenship. Last is an introduction to the articles in this special issue.
