To my daughter’s gender therapist: you were wrong. It has been some months since you and my daughter had the last of four sessions. In the third session I was invited to sit in on a discussion of the effects of T, testosterone, on a human female body. You smiled calmly as you led us through a series of Powerpoint slides, explaining that my daughter’s reproductive organs would atrophy, that she would grow a beard, that her voice would deepen, and that “the phallus” would become enlarged. I sat listening, summoning all of my own skills as a clinical psychologist to not let a tirade loose at you in front of my brittle and fragile 17 year old.
