The change would lead to many intriguing questions: For example, would a man who becomes a woman be able to marry another man? (Probably.) Would an adoption agency be able to uncover the original sex of a proposed parent? (Not without a court order.) Would a woman who becomes a man be able to fight in combat, or play in the National Football League? (These areas have yet to be explored.)
