Questioning the new forms of human fabrication in the light of Marcel Mauss's concept of gift. In this article, we will articulate the logic involved in donations from engenderment material (semen, eggs and embryos), practiced in the field of new reproductive technologies, with the system of exchanges of some archaic societies described by Marcel Mauss in his celebrated article Essay on the gift (1924/1974). This articulation will also be crafted from three important interpreters of this essay - Lévi-Strauss, Maurice Godelier and George Bataille - in order to extract some consequences and clarify some questions that the NRT address to psychoanalysis and vice versa
