Under "conditions related to sexual health", the ICD-11 lists "gender incongruence", which is coded into three conditions:
Gender incongruence of adolescence or adulthood (HA60): replaces F64.0
Gender incongruence of childhood (HA61): replaces F64.2
Gender incongruence, unspecified (HA6Z): replaces F64.9

Persistence
According to the American Academy of Pediatrics, "by age four most children have a stable sense of their gender identity" and "research substantiates that children who are prepubertal and assert [a transgender or gender diverse identity] know their gender as clearly and as consistently as their developmentally equivalent peers who identify as cisgender and benefit from the same level of social acceptance".If gender dysphoria persists during puberty, it is very likely permanent. For children with gender dysphoria, the period between 10 and 13 years is crucial with regard to long-term gender identity. Factors that are associated with gender dysphoria persisting through puberty include intensity of gender dysphoria, amount of cross-gendered behavior, and verbal identification with the desired/experienced gender (i.e. stating that they are a different gender rather than wish to be a different gender).Prospective studies have reported that gender dysphoria in children is more heavily linked to adult homosexuality than to an adult transgender identity, especially with regard to boys.
The studies state that the majority of children diagnosed with gender dysphoria did not desire to be the other sex by puberty, with most growing up to identify as gay, lesbian, or bisexual, with or without therapeutic intervention.The prospective studies have been criticized  on the basis that they counted as desistance cases where the child was simply gender-nonconforming rather than dysphoric. While they met the criteria for gender identity disorder as defined in the DSM-III or DSM-IV, many would not have met the updated criteria for gender dysphoria in the DSM-5, established in 2013. In addition, prior to the DSM-III in 1980, there was no diagnostic criteria for gender dysphoria, so research on desistance rates published prior to 2000 reported inflated numbers of desistance.Additionally, the evidence offered has been criticized for citing studies which have been labelled conversion therapy for discouraging social transition and trying to prevent a transgender outcome. The studies have been used to argue for more caution in socially or medically transitioning transgender youth; however, they have been criticized as irrelevant due to tracking diagnoses rather than tracking evolution of gender identity or desire to transition. In addition, Bonifacio et al. state that "there is research to suggest" that some desistance of GD "may be caused, in part, by an internalizing pressure to conform rather than a natural progression to non–gender variance. "According to a review published in 2022 considering more recent studies, the majority of pre-pubertal children who socially transition persist in their identity in 5 to 7 year follow ups.
