Alabama’s state legislators gave final approval to a bill that could imprison doctors for up to to a decade for prescribing medical treatments to transgender youth.

The bill criminalising gender-affirming care for transgender people younger than 19 years old is the first in the US to make healthcare for young transgender patients punishable by up to 10 years in prison.

Senate Bill 184 prohibits doctors from prescribing puberty blockers, hormone therapy and surgeries for transgender youth, though Alabama health care providers have repeatedly told legislators that such surgeries were not performed on minors in the state.

The legislation – which passed the state House on 7 April following its passage in the Senate earlier this year – also prohibits “a nurse, counselor, teacher, principal or other administrative officials at a public or private school” from “encouraging or coercing a minor” to withhold from a parent or guardian whether their “perception of his or her gender or sex is inconsistent with the minor’s sex.”
