Spencer Cox on Saturday signed a bill banning gender-affirming surgery on minors who have not been diagnosed with gender dysphoria.

It ties the hands of doctors and parents by restricting access to the only evidence-based treatment available for this serious medical condition and impedes their ability to fulfill their professional obligations," the letter said.

The bill’s sponsor, state Sen. Mike Kennedy, a Republican family doctor has said government overnight is necessary for vital health care policy related to gender and youth.

People gather in support of transgender youth during a rally at the Utah State Capitol Tuesday, Jan. 24, 2023, in Salt Lake City.

"More and more experts, states and countries around the world are pausing these permanent and life-altering treatments for new patients until more and better research can help determine the long-term consequences."

Cox also signed another measure that would give students school-choice style scholarships to attend schools outside the public education system.
