What is gender identity? Why do some people feel an inconsistency between their natal sex and the gender they consider themselves to be, and when and why does that “dysphoria” begin? A few very young children, mostly boys, prefer the clothes, names, and activities of girls before they even have a concept of “boy” and “girl.” But do the reasons for their gender incongruence apply to the adolescents, mostly girls, who show no interest in transitioning until puberty or later? How shall we determine which procedures are safest and most effective for treating children and young teenagers with gender dysphoria, without assuming they all are the same as the countless others who are nonbinary, “questioning,” and experimenting?
