Gamete donation hos come to question and broaden the notion of kinship. The hegemony of an biogenetic model has been an obstacle for parents of these families to incorporate donation into their history. From the beginning of the technique the parents chose not to tell their descent the history of their conception, often for fear that their filial relationship would be delegitimized. Over time, an openness to disclosure has been observed. This change goes hand in hand with the development of research in the area, which began by asking about the psychological well-being of those born by donation. Then investigating the relational aspects of families conceived in this way and questioning the benefits of disclosure. Subsequently, it was possible to study the perceptions regarding their origin of people born by donation. Finally, the impossibility of anonymity in the era of direct consumer genetic testing has been published. The way of understanding donor reproduction has evolved, from a medical model in focus is to achieve a healthy pregnancy, a family formation model, in which the motivation is to contribute to forming well-functioning families. This has implications in counseling to those who participate in the process, and in the guidelines that scientific societies and ethics committees affect donor reproduction programs.
