"Analysis of procedure-specific trends by age revealed a number of important findings. First, GAS procedures were most common in patients aged 19 to 30 years. This is in line with prior work that demonstrated that most patients first experience gender dysphoria at a young age, with approximately three-quarters of patients reporting gender dysphoria by age 7 years. These patients subsequently lived for a mean of 23 years for transgender men and 27 years for transgender women before beginning gender transition treatments. Our findings were also notable that GAS procedures were relatively uncommon in patients aged 18 years or younger. In our cohort, fewer than 1200 patients in this age group underwent GAS, even in the highest volume years. GAS in adolescents has been the focus of intense debate and led to legislative initiatives to limit access to these procedures in adolescents in several states."
