Trump administration revokes transgender health protection

It doesn't look like it bans sex changes, likely just heath coverage of sex changes:

Behind the dispute over legal rights is a medically recognized condition called “gender dysphoria” — discomfort or distress caused by a discrepancy between the gender that a person identifies as and the gender at birth. Consequences can include severe depression. Treatment can range from sex-reassignment surgery and hormones to people changing their outward appearance by adopting a different hairstyle or clothing.
