More and Less than Equal
本文研究男性在生殖过程中的贡献如何被理解，通过分析孕前保健和精子库的数据，揭示不同生殖阶段中性别知识如何产生不同的生殖等式，并提出新的研究议程。
In both social science and medicine, research on reproduction generally focuses on women. In this article, we examine how men's reproductive contributions are understood. We develop an analytic framework that brings together Cynthia Daniels' conceptualization of reproductive masculinity (2006) with a staged view of reproduction, where the stages include the period before conception, conception, gestation, and birth. Drawing on data from two medical sites that are oriented to the period before pregnancy (preconception health care and sperm banks), we examine how gendered knowledge about reproduction produces different reproductive equations in different stages of the reproductive process. We conclude with a new research agenda that emerges from rethinking the role of men and masculinity in reproduction.
