A 15-year study of 2,772 individuals, conducted by researchers at the University of Groningen, found that 11% of 11-year-olds had transgender inclinations—but that only 4% did at the age of 26.
“Gender non-contentedness, while being relatively common during early adolescence, in general, decreases with age and appears to be associated with a poorer self-concept and mental health throughout development,” the researchers stated.
