South Dakota is projected to ban nearly all forms of extreme transgender medical procedures being performed on children in the state after the senate there overwhelmingly passed a bill ordering the policy.

The bill, which Republican Gov. Kristi Noem is expected to sign, would forbid doctors from prescribing drugs such as puberty blockers and/or synthetic hormones meant to mimic those of the opposite sex. 

Doctors would also be barred from performing irreversible surgeries on minors such as castrations and hysterectomies, which transgender-identified patients often undergo in order to try and approximate the body of someone of the opposite sex. 

The bill passed the Senate on a 30-4 vote.
