+Peer-reviewed scientific papers aren't enough for you? (They could be cherry-picked; there are lots of scientific journals, and no doubt a lot of bad science slips through the cracks of the review process.) Want something more indicative of a consensus among practitioners? Fine. The [_Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition_](https://en.wikipedia.org/wiki/DSM-5) (the definitive taxonomic handbook of the American Psychiatric Association) [says the same thing](https://sillyolme.wordpress.com/2021/02/06/american-psychiatric-association-supports-the-two-type-transsexual-taxonomy/) in [its section on gender dysphoria](/papers/DSM-V-gender_dysphoria_section.pdf) ([ICD-10-CM codes](https://en.wikipedia.org/wiki/ICD-10-CM) F64.1 and F64.2):

+> In both adolescent and adult natal males, there are two broad trajectories for development of gender dysphoria: early onset and late onset. _Early-onset gender dysphoria_ starts in childhood and continues into adolescence and adulthood; or, there is an intermittent period in which the gender dysphoria desists and these individuals self-identify as gay or homosexual, followed by recurrence of gender dysphoria. _Late-onset gender dysphoria_ occurs around puberty or much later in life. Some of these individuals report having had a desire to be of the other gender in childhood that was not expressed verbally to others. Others do not recall any signs of childhood gender dysphoria. For adolescent males with late-onset gender dysphoria, parents often report surprise because they did not see signs of gender dysphoria in childhood. Adolescent and adult natal males with early-onset gender dysphoria are almost always sexually attracted to men (androphilic). Adolescents and adults with late-onset gender dysphoria **frequently engage in transvestic behavior with sexual excitement.**
