The Supreme Court is set to hear arguments Wednesday challenging a Tennessee law that bans so-called "gender-affirming care" for minors including surgery and the prescription of puberty blockers

Three children that identify as transgender and their parents are challenging the law, in the case, United States v. Skrmetti, according to NPR.

The bill bans such care, which also includes hormone therapy, for residents younger than 18 attempting to switch genders. 

"You can't get a tattoo in Tennessee unless you're 18. You can't smoke. You can't drink," says state Sen. Jack Johnson, who introduced the measure. 

He also says the law prevents minors from making decisions that they will regret later.

Tennessee Attorney General Jonathan Skrmetti says lawmakers took “measured action” in 2023 when they prohibited gender affirming care for minors to protect them from “irreversible, unproven medical procedures.” But plaintiff attorneys argue the law violates the Constitution’s equal protection clause.
