Best interests of a child-gender affirming treatments.

HB 156 establishes a legal presumption in Wyoming court decisions about children's best interests: it is conclusively not in a child's best interest to undergo gender transition or reassignment procedures. The bill defines prohibited procedures to include certain surgeries (like hysterectomy or orchiectomy), mastectomies, and specific hormone treatments (such as puberty blockers or supraphysiologic hormone doses), while excluding care for children with medically verified conditions like disorders of sex development or central precocious puberty. This presumption applies to family court cases involving custody, adoption, visitation, and protection orders. The bill amends multiple Wyoming statutes to incorporate this standard, affecting court rulings on minors' care.
