ICD-11 represents major shift in the classification of gender identity-related health
The World Health Organization’s International classification of diseases 11th revision (ICD-11) came into effect in February 2022 and includes significant updates to the classification of gender identity-related health compared with ICD 10th revision (ICD-10).
Gender identity disorder" and "transsexualism" have been replaced with "gender incongruence".
New diagnostic categories have been moved out of the "Mental and behavioral disorders" chapter and into the new "Conditions related to sexual health" chapter.
Minor changes have also been made to terminology used in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, Text Revision (DSM-5-TR), published in March 2022.
Use of "experienced gender" rather than "desired gender".
Use of "gender-affirming" rather than "cross-sex" in relation to treatment and medical procedures.
It is hoped that the updates to language used in ICD-11 and DSM-5-TR will help remove stigma associated with gender diversity.
Gender dysphoria, also known as gender incongruence, is present when there is a distressing dissonance between a person's biological sex and associated social gender role, as assigned at birth, and that person's sense of their own gender.
Many adults with gender dysphoria will not seek specialist medical intervention, and prevalence is likely underestimated.
In children and adolescents, gender dysphoria is particularly complicated, may have higher comorbidity, and may change form as patients mature, making specialist assessment particularly important. This topic covers the management of gender dysphoria in adults only.
Subspecialty consultation is required for any patient with suspected or confirmed gender dysphoria (gender incongruence). Treatment is complex and should only be undertaken as part of a package of care provided by a multidisciplinary team with extensive experience in this area.
Gender nonconformity is when a person’s gender identity, role, or expression differs from the cultural norms prescribed for people of a particular sex.
Gender dysphoria, also known as gender incongruence, is present when there is a distressing dissonance between a person's biological sex and associated social gender role, as assigned at birth, and that person's sense of their own gender. "Gender identity disorder" and related terms should be avoided due to their connotations with mental ill health and the associated stigma.

People with gender dysphoria express the desire to live and be accepted in a social gender role other than that assigned at birth. Gender dysphoria is usually accompanied by a sense of discomfort with one's own body, particularly those primary and secondary sexual characteristics others use to assign social gender role, such as genitals, breasts, or facial hair.
Only some gender nonconforming people experience gender dysphoria at some point in their lives.
The historical terms "transvestite" and "transsexual" are considered pejorative, and their use should be avoided.
