Abstract
In the aftermath of the Supreme Court’s 2022 decision to overturn the federal right to abortion, much public and political debate has surrounded gestating and in vitro embryos’ “personhood.” In this paper, I draw on 15 months of participant observation in biomedical spaces of infertility to reveal how embryos can be enacted as not only unborn children but as many different kinds of entities. I examine how embryos become “multiple” as in vitro fertilization (IVF) professionals inseminate, monitor, and transfer them into patients’ bodies: enacting them as makeable, contingent, recordable, animatable, predictable, introducible, praisable, and appraisable entities. Providing a new perspective into the varied ontologies of in vitro embryos, this paper has far-reaching implications for the anthropological study and politics of reproductive medicine and politics today
