Health care for trans kids has been in the spotlight, with battles over what the science says and tons of U.S. states restricting the care that children can get. And then there’s a new report out of the UK, called the Cass Review, saying that a bunch of the evidence that doctors have been relying on to treat trans kids is “remarkably weak.” So what’s going on here? What is the best health care for trans kids? We sort through the science with Professor Stephen Russell, Dr. Cal Horton, and Dr. Ada Cheung.

UPDATE 6/6/24: In a previous version of this episode, we said a study was published this year, when it was actually published last year. The episode has been updated.
