In the midst of a review of the law of bioethics, Blanche Streb, doctor of pharmacy and director of training and research at the Vita Alliance, reviews his book "Babies sur Mesure" (Éditions Artège). A particularly comprehensive book on the true implications of medically assisted procreation. From progressive commodification to selective sorting of reproduction, the author is alert on this path that leads to a world of "the best" in disregard of ethics and the common good.
