MONTGOMERY, Ala. — A federal judge on Friday blocked part of an Alabama law that made it a felony to prescribe gender-affirming puberty blockers and hormones to transgender minors.

U.S. District Judge Liles Burke issued a preliminary injunction to stop the state from enforcing the medication ban, which took effect May 8, while a court challenge goes forward. The judge left in place other parts of the law that banned gender-affirming surgeries for transgender minors, which doctors had testified are not done on minors in Alabama. He also left in place a provision that requires counselors and other school officials to tell parents if a minor discloses that they think they are transgender.
