"Sex refers to the biological designation of a person as either ‘male’ or ‘female’ based on their anatomy (e.g. reproductive organs) and/or their biology (e.g. hormones). Gender refers to the traditional or stereotypical roles, behaviours, activities and attributes that a given society considers appropriate for men and women.

Gender identity is one’s internal, deeply held sense of one’s gender. For transgender people, their own internal gender identity does not match the sex they were assigned at birth. Most people have a gender identity of man or woman (or boy or girl). For some people, their gender identity does not fit neatly into one of those two choices. Unlike gender expression, gender identity is not visible to others."
