Abstract
This article seeks to outline the main features of the stereotype of family promoted by the emblematic institution of the Argentine eugenics movement, the Argentine Eugenics Society (Sociedad Argentina de Eugenesia), an organization founded in 1945 that remained active in the country until the 1970s. It explores the conduct expected both of the man/husband and of the woman/wife, and shows the principal behaviors required to constitute the ideal family, the outlines of which were based on set of sexual moral with an eminently religious bias.
