One study showed that, without social transition, nearly two-thirds of pre-teen gender-dysphoric males grow up to be gay or bisexual.

A University of Toronto study [1] found that 63.6% of boys with early onset gender dysphoria, who received ‘watchful waiting’ treatment and no pre-pubertal social transition, grew up to be gay or bisexual. 

Only 12% of the study participants continued to identify as transfeminine.
