(5) “Male” means a member of the human species who, under normal development, has XY chromosomes and produces or would produce small, mobile gametes, or sperm, during his life cycle and has a reproductive and endocrine system oriented around the production of those gametes.

(10) “Social transitioning” means acts other than pharmaceutical or surgical interventions that are offered as treatment to a minor for the purpose of the minor presenting as the opposite sex or an identity other than the minor's sex, including the changing of a minor's preferred pronouns or dress and the recommendation to wear clothing or devices, such as binders, for the purpose of concealing a minor's secondary sex characteristics.
