The ‘good’ of extending fertility: ontology and moral reasoning in a biotemporal regime of reproduction

Since the emergence of in-vitro fertilization (IVF), a specific set of technologies has been developed to address the problem of the ‘biological clock’. The medical extension of fertility time is accompanied by promissory narratives to help women synchronize conflicting biological and social temporalities. This possibility also has a transgressive potential by blurring one of the biological landmarks – the menopause – by which reproductive lives are organized and governed. These new ways of managing, measuring and controlling reproductive time have renewed debates on the age limits of motherhood and the moral legitimacy of medical intervention into age-related fertility decline. Building on Amir’s feminist concept of biotemporality, this paper questions what happens when the ontological foundations of age-limited motherhood are disrupted by technologies which allow fertility to be extended. It discusses the reconfigurations of the ontological boundaries of the facts of life in the light of literature on reproductive technologies and temporality. Through the Swiss experience, the paper shows how medical experts are drawn into negotiating the ontological boundaries of age-limited motherhood along the binaries of the normal/pathological and the biological/social. Questioning the purpose of medical interventions in what are seen as facts of life, they produce different configurations of moral reasoning where what is natural undergoes shifts which both reinforce the normative order and subvert it.
