How people view themselves and what they call themselves—whether they identify as masculine, female, a combination of the two, or neither—depends on their fundamental sense of gender. The sex a person is assigned at birth may or may not match their gender identification.
The outward manifestation of one's gender identification, commonly exhibited through behaviour, attire, physical traits, or voice, and which may or may not adhere to socially accepted behaviours and features typically associated with either being masculine or feminine.
The process through which some people attempt to more precisely align their internal understanding of gender with its external manifestation. Some persons undergo social transition, in which case they may start wearing differently, using other names and pronouns, or become accepted as a different gender in society. Some people go through physical transformations when they use medical procedures to change their bodies.
