ABSTRACT
Pre-implantation diagnosis with the selection of a zygote brings up the question of choice. By going through a procedure of in vitro fertilisation, pre-implantation diagnosis seeks to make the prediction as early as possible, as far upstream in the process as possible, by selecting the zygotes that are not affected. It is true that the purpose of any prediction is to know if what one fears is there, before it is there; to know rather than to predict something that is already underway, that has already started. Even more so when the prediction precedes conception, and is accompanied by the selecting of the zygote that will be implanted. Through the child one would like to escape human limitations, escape from the inevitability of death that is unavoidably brought to the fore by procreation and birth themselves. In the Imaginary, procreation is in opposition with death while simultaneously containing it, since by introducing life it also introduces death.
