Causes of gender incongruence

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, 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.[2] Studies conducted on twins prove that there are genetic causes of gender incongruence, although the precise genes involved are not known or fully understood.[3][4][5]

Of 23 monozygotic female and male twins, nine (39.1%) were concordant for GID; in contrast, none of the 21 same‐sex dizygotic female and male twins were concordant for GID, a statistically significant difference (P = 0.005)... These findings suggest a role for genetic factors in the development of GID.

Combining data from the present survey with those from past-published reports, 20% of all male and female monozygotic twin pairs were found concordant for transsexual identity... The responses of our twins relative to their rearing, along with our findings regarding some of their experiences during childhood and adolescence show their identity was much more influenced by their genetics than their rearing.
