Mary and Jane don’t know why they feel like women though they were born boys. Jane proffers the obviously wrong explanation that it’s because they have an extra chromosome. But even the experts aren’t certain about what causes gender identity disorder.
The most current (but still mysterious) explanation is that something happens to the part of the Central Nervous System responsible for gender identity in the womb. Theories that transsexuality is a mental illness or related to upbringing, social interactions and sexual experiences have largely been debunked.
