Behind Florida’s decision to block clinical services for transgender adolescents is a talking point — repeated by the state’s governor and top medical authorities — that most cases of gender incongruence fade over time.

The Florida Board of Medicine voted Nov. 4 to approve a rule that barred physicians from performing surgical procedures on minors to alter “primary or secondary sexual characteristics” and from prescribing them medication to suppress puberty and hormones. The rule included an exception for patients who were already receiving those treatments.

Two days later, Florida’s Republican governor, Ron DeSantis, said gender-affirming care is “an example of ideology overtaking the practice of medicine,” touting that he worked with the board to take a stand against it.

“Over 80% of the dysphoria amongst teenagers resolves itself by the time they become older,” DeSantis said during a Nov. 6 campaign event. “So why are you mutilating their body parts?”
