[To benefit tomorrow's children: female participation in Brazilian eugenics, 1918-1936].

This text analyzes female participation in Brazilian eugenics and medical discourse on the roles and social functions of the sexes during the first half of the twentieth century. In examining the production of two women, Ítala Silva de Oliveira and Eunice Penna Kehl, we maintain that certain women were effectively engaged in the eugenics movement and worked to bring women closer to eugenics. This analysis makes it possible to explore a pedagogical dimension of eugenics and of the popularization of this movement by attempting to form a hygienist and eugenist consciousness among women.
