Final answer:
An individual's identification with a different sex than their biologically assigned one is not necessarily considered a disorder; this is true. Gender identity is a personal internal sense and not being aligned with one's biological sex is not inherently a condition of distress, though some may experience gender dysphoria.
Step-by-step explanation:
An individual's identification with a sex other than the biologically assigned one does not necessarily have to be considered a disorder. The statement in question is true. Gender identity refers to an individual's internal sense of being male, female, neither, both, or another gender, which may not correspond to their biological sex. The term gender dysphoria is used to describe individuals who experience significant distress or dysfunction in relation to the gender they were assigned at birth, but not all individuals who identify with a different gender experience this dysphoria. In 2019, the World Health Organization reclassified gender identity disorder as gender incongruence, categorizing it under sexual health rather than as a mental disorder, reflecting a broader understanding and acceptance of variations in gender identity.
