A transgender clinic in St. Louis will no longer prescribe gender hormones to minors thanks to a new state law that exposes doctors to lawsuits if they provide such treatments.

The Transgender Center at St. Louis Children’s Hospital “will no longer prescribe puberty blockers or cross-sex hormones to minors for purposes of gender transition,” Washington University, which is affiliated with the hospital, announced on Monday.

Missouri’s new law bans putting children on puberty blockers or cross-sex hormones and performing gender surgery on minors. The law includes an exception for patients already on hormone treatments, allowing them to continue taking them.
