OBJECTIVE Demand from minors with complaints of gender dysphoria has increased in recent years. This increase has been more pronounced in adolescent trans men in some international research studies. The first objective of this research study was to determine the sex/gender ratio of minors requesting a consultation in the Gender Identity Treatment Unit of the Principality of Asturias (UTIGPA) and presenting complaints of gender dysphoria. The second objective was to analyse the relationship of the sex/gender ratio with the age variable at which they requested the first consultation and the year in which they requested it. METHODS The sample consisted of 42 children under 18, attended between January 2016 and January 2019. The medical records were then reviewed to obtain information. Descriptive statistics were analysed with the collected data. RESULTS The sex / gender ratio over the period was 2/1 in favour of trans men. The average age at the request for consultation was 15.02 years (SD=1.84), with a range of 6 to 17 years. A higher percentage of applications was recorded (35.7%) in 2018, mostly made by trans men (93.3%). CONCLUSIONS There was an inversion of the sex/gender ratio, a favour of trans men, over the last 3years, and an increase in the number of applications by adolescent trans men, coinciding with several international investigations.
