==Measurement==
No objective measurement or imaging of the human body exists for gender identity, as it is part of one's subjective experience.<ref>{{cite journal | vauthors = Dahlen S | title = De-sexing the Medical Record?

The central claim rests on a consistent declarative statement of the trans patient's subjective experience of self-hood. Therefore, we cannot prove or disprove a gender identity. Gender identity is a deeply held, spiritually significant, personal belief that can neither be confirmed nor rebutted by external evidence and biological data. | doi-access = free }}</ref><ref>{{cite journal | vauthors = Griffin L, Clyde K, Byng R, Bewley S | title = Sex, gender and gender identity: a re-evaluation of the evidence | journal = BJPsych Bulletin | volume = 45 | issue = 5 | pages = 291–299 | date = October 2021 | pmid = 32690121 | pmc = 8596152 | doi = 10.1192/bjb.2020.73 | quote = As a pure subjective experience, it may be overwhelming and powerful but is also unverifiable and unfalsifiable. | doi-access = free }}</ref> Numerous clinical measurements for assessing gender identity exist, including questionnaire-based, interview-based and task-based assessments.
