[Some difficulties in the "paternalization" process in medically assisted reproduction].

Based on the observation of a child born by IAD, suffering of depression and presenting a school phobia, the author discusses the feeling of impotency experienced by the legal father. In another case, the grand-father-to-be is ready to donate his sperm so as to avoid issues on genetics: it is doubtful that such birth conditions would permit a healty organization of fatherhood. Included in the article are references on the literature concerning psychopathology of children born by IAD.
