President Donald Trump signed a broad executive order targeting transition-related medical care for minors Tuesday.

The order, titled “Protecting Children From Chemical and Surgical Mutilation,” intends to restrict access to gender-affirming medical care — including puberty blockers, hormone therapy and surgery — for minors, which it defines as those younger than 19.

It prohibits federal funding from covering such care for minors, restricts research and education grants to medical schools and hospitals, and directs the secretary of Health and Human Services to issue regulations to end such care for minors.

The order also directs all federal agencies to rescind guidance from the World Professional Association for Transgender Health, or WPATH, a nonprofit association dedicated to transgender medical care that issues guidance that is widely used by health care professionals.
