What happens when an intersex child is born in Brazil? To answer this and other questions, this study aims to present a theoretical study of intersexuality. Initially, there will be performed an analysis of the divergences involving the theme and then, a reflection on bodies to observe, through the interpretive transformations that they have suffered historically, if the sex and gender marks form a binary standard that would have the power to turn them invisible if not attended. Through collected stories, we seek to understand the criteria used to label bodies as intersex and the experiences of its protagonists. An analysis of the external interventions that these individuals were and are subject to birth, will also be conducted to understand the contemporary situation. In this sense, Winnicott s theory will be an important tool to not only question the current protocol, but also bring the vision of the constitution of subjectivity in childhood and think of an alternative of care that respects this construction. The roles played by the Brazilian Law finalize the study to investigate whether it has functioned as an obstacle or as a guarantor of the rights of intersex infants. We examine whether there are rolls being held in line with international changes, checking in current legislation the existing obstacles and the possibilities to think about the matter. Finally, a path from the perspective of the Civil-constitutional Law will be designed, seeking the admission of plural existences, i.e., new meanings to the consciousness of self, able to allow the full development of identities and respect the human dignity.
