The infertility treatments option by reproduction cells donation introduces a new scene that allows us to differentiate between cell reproduction donors, genitors and fathers. This new scene is different from the situations of adoption or wrongful appropriation of childs. Ken Scott´s film Delivery man gives us the opportunity to make a distinction –that genetic science don´t do- between two questions: Who is the father? and What is a father? The genetic determination of the origin of the cells used to give birth to a human being does not solve the problem of parenthood. Parenthood doesn´t links with biological issues but with holding a symbolic function for a subject named as a son.
