Causes of Gender dysphoria

Little is known about the cause of gender dysphoria.

There has been some research claiming to show that male and female brains show some difference in structure and that people with gender dysphoria have brains structured like those of their psychological rather than physical sex. This suggests the cause occurs during the development of the brain while in the womb, however the research is inconclusive.

Research has also shown that a significant proportion of male transsexuals have abnormally low levels of HY antigen (This is present in the cells of males but not in the cells of females).b

Many believe gender dysphoria is caused by hormonal alteration of the nervous system of developing foetus.
