Use the pronoun that matches the person’s authentic gender. A person who identifies as a certain gender, whether or not that person has taken hormones or undergone surgery, should be referred to using the pronouns appropriate for that gender. If you are not certain which pronoun to use, ask the person, “What pronouns do you use?”

(Note for UW­–Madison communicators: If a person uses pronouns that are not familiar to most readers [such as xe or ze], include an explanation on first reference.)
