The US Supreme Court on Wednesday hears a challenge to a Tennessee law banning gender-affirming medical treatments for transgender minors, a case with repercussions for similar state prohibitions across the country.

At issue is a Tennessee law that bans access to hormones, puberty blockers, and other treatments for trans kids in the state.

Tennessee’s attorney general is set to defend the state’s gender affirming care ban for minors in the U.S. Supreme Court Wednesday against challengers who say the 2023 law endangers children. While attorneys for the plaintiffs claim the law violates the Constitution’s equal protection clause,

The court will consider whether states can block doctors from prescribing gender treatments to patients under the age of 18, in its biggest case this term.

The issue of transgender rights animated the presidential campaign. Now it has made its way to the Supreme Court, and in more ways than one.

The justices are considering whether a Tennessee law banning gender-affirming care for minors violates the Constitution’s equal protection clause.
