Goals of the studyThe diversification of studies about the development of children in same-sex families, as well as the methodological advances in these studies, make it possible to better take into account the specificity of the different options available to same-sex couples to create a family. The revision of the bioethics laws in France in 2018 invites us to examine in detail research specifically analyzing the development of children of lesbian mothers conceived by assisted reproductive technics (ART). MethodWe identified and analyzed 16 international publications (published between 1997 and 2017) concerning the study of 9 cohorts of children of lesbian mothers conceived by ART. We also supplemented this analysis with, in particular, the examination of 24 publications about planned lesbian families that do not distinguish between procreation situations with and without medical assistance (i.e., ART or self-insemination), and we also considered these results in relation to studies of children adopted by same-sex couples. Results and conclusionThe studies essentially reveal a developmental homogeneity across children of lesbian mothers and those of heterosexual parents (conceived naturally or by ART) whether we focus on the developmental characteristics of children or on family relationships. These studies also specifically analyze the issues of access to donor information and the stigmatization that these families may face.
