On September 12th 2017, as part of the so-called Lacanian Week in Buenos Aires, the 4th Study-Day of the New Red Cereda took place under the title "Sexual Diversity" - The Paths of the Choice of Sex in Childhood- Diagonal Americana. This was an opportunity in which the Interdisciplinary Center for Child Studies (CIEN) intervened. By virtue of this, we spoke with Alexander Daumas and Hernan Vilar so that they tell us about what happened there.
