A Republican legislator in Oklahoma has moved to ban gender transition procedures from being provided to anyone under the age of 21.

The bill seeks to ban medical professionals from providing or referring controversial procedures like puberty blockers, cross-sex hormones, and sex-change surgeries for those under 21. The legislation would also block such procedures or services on the young from being tied to public funding, and any organization or hospital found in violation would lose such funding.

“It’s irresponsible for anybody in health care to provide or recommend life-altering surgeries that may later be regretted,” said Republican Oklahoma State Rep. Jim Olsen, who introduced HB 1011 on Thursday.
