The gender transition process varies according to each individual.
It often entails a social change in which a person changes the way they dress or the pronouns they prefer to use. It may even involve a legal name change.
Gender transition is not always a surgical operation, and one does not need to undertake any such operation to identify as transgender.
There may be medical components to some transgender people’s transition process, but this is considered personal information and needs to be treated as such.
