Dissertation: "Medicalising uncertainty. An Ethno-sociological study on autologous
oöcyte cryopreservation in France”

This thesis is a study of the complex social, medical, legal, bodily, technical and
kinship relations that shape oocyte self-preservation (oocyte vitrification for
autologous purposes) in France. The study focuses both on the normative dimension
that structures access to this biomedical technology and on the practices and
experiences of those directly involved (women having theirs eggs frozen, as well as
the practitioners and laboratory technicians who make it medically and technically
possible) and on the technical dimension of oocyte freezing. Drawing on a 20-month
fieldwork (2018 - 2019), this research presents an ethnosociological study combining
semi-structured interviews and an ethnographic research. Direct observation took
place in three French centres for medically assisted procreation (centres d’assistance
médicale à la procréation-Centre d’Étude et de Conservation des Œufs et du sperme,
AMP-CECOS) and, in particular, in their in vitro fertilisation (IVF) laboratories. On the
one hand, this work proposes to deconstruct the three legal-medico categories of
access to oocyte freezing in France: medical egg freezing or “fertility preservation,”
egg sharing and so-called social egg freezing. On the other hand, it questions the link
between oocyte self-preservation, procreation and motherhood. Contrary to what one
might think, my fieldwork leads suggest that oocyte self-preservation is not
necessarily a biotechnology for procreation. My analysis allows me to argue that egg
freezing is a kind of medicalisation of uncertainty from an institutional, subjective and
technical point of view.
