>The exact rate of desistance varied by study, but overall, they concluded that about 80 percent trans kids eventually identified as their sex at birth. Some trans activists and academics, however, argue that these studies are flawed, the patients surveyed weren't really transgender, and that mass desistance doesn't exist.
>Indeed, some of the studies cited by Cantor had sample sizes as low as 16 people and were more than 40 years old, and one was an unpublished doctoral dissertation. But the most recent study, published in 2013 in the Journal of the American Academy of Child and Adolescent Psychiatry, followed up with 127 adolescent patients at a gender identity clinic in Amsterdam and found that two-thirds ultimately identified as the gender they were assigned at birth.
This does not imply any percentage of patients who underwent surgery to "restore" their original sex. Orchiectomies, mastectomies, and histerectomies are irreversible in any case, not to mention bottom surgery.
