Scientific developments related to human reproduction opens a wide range of new possibilities and combinations in order to the gestation of a child, separated from the need for sexual intercourse between two persons of opposite sex. These new scenarios -some of which described in this paper- convened to the legal field for the establishment of certain regulations, and moreover it interpellates the field of subjectivity with unavoidable questions about parentage. This discursive crosslinking that occurs before the intervention of science in the origin of life, becomes the discussions where they converge complicated. One of the problems is related to the so-called identity right, which we circumscribe here as the right to know the own historical biological origin, and in a direct relation to this, the maintenance or the anonymity of donor germ cells. We use a reference to a film that brings this situation into play. On the other side, specifically from psychoanalysis, we address the issue of the construction of the origin, and we make some distinctions between myth and family novel.
