Causes of gender incongruence
From Wikipedia, the free encyclopedia
Gender incongruence is the state of having a gender identity that does not correspond to one's sex assigned at birth. This is experienced by people who identify as transgender or transsexual, and often results in gender dysphoria.[1] The causes of gender incongruence have been studied for decades.
Transgender brain studies,[2] especially those on trans women attracted to women (gynephilic), and those on trans men attracted to men (androphilic), are limited, as they include only a small number of tested individuals.[3] Studies conducted on twins suggest that there are likely genetic causes of gender incongruence, although the precise genes involved are not known or fully understood.[4][5][6]
