GENDER DETRANSITION: A CRITICAL REVIEW OF THE LITERATURE

Introduction. Gender detransition is the act of stopping or reversing the social, medical, and/or administrative changes achieved during a gender transition process. It is an emerging phenomenon of significant clinical and social interest. Methods. We systematically searched seven databases between 2010 and 2022, manually traced article references, and consulted specialized books. Quantitative and content analyses were carried out. Results. We included 138 registers, 37% of which were empirical studies and 38.4% of which were published in 2021. At least eight terms related to detransition were identified, with differences in their definitions. Prevalence estimates differ according to the criteria used, being lower for detransition/regret (0-13.1%) than for discontinuation of care/medical treatment (1.9%-29.8%), and for detransition/regret after surgery (0-2.4%) than for detransition/regret after hormonal treatment (0-9.8%). More than 50 psychological, medical, and sociocultural factors influencing the decision to detransition and 16 predictors/associated factors are described. No health or legal guidelines are found. Current debates focus on the nature of gender dysphoria and identity development, the role of professionals in accessing medical treatments, and the impact of detransition on future access to these treatments. Conclusions. Gender detransition is a complex, heterogeneous, under-researched, and poorly understood reality. A systematic study and approach to the topic is needed to understand its prevalence, implications, and management from a healthcare perspective.
