Twenty-five is not a neurobiologically determined age of maturity for gender-affirming medical decision-making

Among the increasing threats to the healthcare of transgender and gender-diverse people globally, are efforts to deny gender-affirming medical care to people under age 25 typically justified by stating that the human brain is not developed until the mid-to-late 20's. Thus, this line of reasoning states young adults are not sufficiently mature to be responsible for autonomous healthcare decision-making— at least in regard to gender-affirming care.

Abstract:
Among the increasing threats to the healthcare of transgender and gender-diverse people globally, are efforts to deny gender-affirming medical care to people under age 25 typically justified by stating that the human brain is not developed until the mid-to-late 20's. Thus, this line of reasoning states young adults are not sufficiently mature to be responsible for autonomous healthcare decision-making— at least in regard to gender-affirming care.
