Améliorer les pratiques de soins pour les personnes présentant une variation du développement du sexe en Suisse. L’École de Lausanne (depuis 2005)

This article presents a short history of the Lausanne School or “Swiss model” (as it is sometimes called abroad) created in the context of an interdisciplinary “SHS and gender in medicine” project we launched in 2005 to improve medical care for persons with a variation of sex development (VSD). We reflect here on our collaborative work experience for more than 10 years now in order to highlight the conditions of possibility, the reasons, the goals and the various development modalities of a VSD teaching and hospital team committed to multidisciplinary care. Our team is also known for its commitment to differ early genital surgeries so as to respect children’s right to participate in medical treatment decisions. The Lausanne experience testifies to the possibility of changing clinical practices to implement “a less cutting, more talking” model of care and, at the same time, of developing a medical ethics “from below” to overcome the lack of ethical recommendations as it was the case until 2012 in Switzerland.
