A Missouri judge ruled Friday that a ban on gender-affirming health care for minors can take effect on Monday, as scheduled.

The ruling by St. Louis Circuit Judge Steven Ohmer means that beginning next week, health care providers are prohibited from providing gender-affirming surgeries to children. Minors who began puberty blockers or hormones before Monday will be allowed to continue on those medications, but other minors won’t have access to those drugs.

Some adults will also lose access to gender-affirming care. Medicaid no longer will cover treatments for adults, and the state will not provide those surgeries to prisoners.

Physicians who violate the law face having their licenses revoked and being sued by patients. The law makes it easier for former patients to sue, giving them 15 years to go to court and promising at least $500,000 in damages if they succeed.
