In France, embryo donation is allowed since 1994 and it has been scarcely studied. Based on a fieldwork survey, this article tries to understand how people involved in embryo donation, givers as well as recipients, do represent an embryo. Observations, interviews, drawings made by the couples attending embryo donation show that embryo is a plural entity which needs to be thought in the temporality of the art processes and according to the social network into which it takes place, associated with scientific and technological conceptions, as well as moral and religious values.
