Transgender people can benefit from psychological, psychiatric, endocrinological support, sexual reassignment surgery, sexology support and dermatological care. The value of transitional care courses is scientifically recognized. Currently, the modalities of decision and realization of the care paths are heterogeneous on the territory, little standardized, and are the subject of debates between representatives of users and medical teams.~The french national report of IGAS from 2011 warns of the need to argue and legitimize care practices through more numerous, more exhaustive scientific studies, presenting a better level of evidence~Since 2011, no prospective study has been carried out on the national and international level, making it possible to assess the relevance of the planned care modalities. This research project, conducted over five consecutive years at the first contact of a transgender people with a care device, aims to correlate a variation in the quality of life of people with the characteristics of the care methods provided. This is a first proposal to assess care practices for transgender people. The results of this study would first allow us to infer the care modalities most suited to the needs of people. Secondly, secondary hypotheses could support new experimental protocols.
