The surgery of trans people is not apprehended by most of plastic surgeons as a simple surgery for the purpose of morphological transformation. At the same time, the French trans population does not benefit from adequate surgical coverage. Over the past few years, French regulations have simplified the process of reassignment surgeries. In addition, we have witnessed a fairly rapid increase in requests for transition surgery with accelerated and sometimes atypical courses. In recent years, a number of specialists have warned the medical community about the risks of slippage due to a lack of psychological monitoring of certain people beginning a transition process. Quite recently, hybrid transition paths have also appeared which, from a surgical point of view, are no longer limited to ensuring that a native assigned female patient can take on the most masculine appearance possible or the reverse. In this manuscript, we expose the biological, historical and societal place of transidentity and then address the reasons for the warnings of a certain category of the medical population while reassuring the surgical community on the benefits of reassignment surgeries in a controlled context. We end by proposing a few ways to improve the care course of trans people applicable in France.
