At follow-up, gender identity/dysphoria was assessed via multiple methods and the participants were classified as either persisters or desisters. In childhood, 88 (63.3%) of the boys met the DSM-III, III-R, or IV criteria for gender identity disorder the remaining 51 (36.7%) boys were subthreshold for the criteria. In childhood, the boys were assessed at a mean age of 7.49 years (range, 3.33–12.99) at a mean year of 1989 and followed-up at a mean age of 20.58 years (range, 13.07–39.15) at a mean year of 2002. This study reports follow-up data on the largest sample to date of boys clinic-referred for gender dysphoria ( n = 139) with regard to gender identity and sexual orientation.
