Episode 38 - Villain Or Vindicated on Pediatric Gender Care - Dr. Ken Zucker

In 2015, one of the world’s best-known researchers of childhood gender dysphoria lost the clinic he had led for more than three decades. Toronto’s Centre for Addiction and Mental Health closed its child and youth gender identity service and dismissed its clinical lead, psychologist Ken Zucker.

The clinic had come under intense criticism. Some accused it of practising conversion therapy by trying to steer children away from a future transgender identity. An external review found that its approach was out of step with emerging practice, although the reviewers said they could not determine whether it was practising conversion therapy. For many people, Zucker’s dismissal marked the end of an era in which clinicians saw childhood gender dysphoria as something they might try to resolve.

Then the story took another turn. In 2018, CAMH acknowledged serious errors in the review’s account of Zucker’s conduct, apologized to him, and reached a financial settlement. Zucker saw that as a vindication. CAMH, however, stood by its decision to close the clinic. The apology corrected allegations about the man. It did not settle the argument about the care.

That argument has become more urgent. Zucker was not a marginal figure. He chaired the group responsible for sexual and gender identity diagnoses in DSM-5, edited Archives of Sexual Behavior, and helped produce some of the most influential follow-up research on children referred for gender identity concerns. In one study of 139 boys assessed in childhood, only 17 were classified as having persistent gender dysphoria at follow-up. That finding has been cited to argue for patience before assuming a child will need medical transition. But what, exactly, did those studies establish? The children were assessed decades ago, more than a third did not meet the diagnostic threshold at their initial assessment, and the research cannot tell us whether Zucker’s treatment changed their outcomes. Nor can its percentages simply be applied to adolescents presenting for the first time today.

Now the clinical pendulum appears to be moving again, at least in some countries. Following the Cass Review, England has moved toward broader assessment of young people’s mental health and development before specialist treatment. Sweden has urged greater caution with medical interventions for minors. Those changes revive questions Zucker spent his career asking: How does dysphoria develop? Which young people will continue to experience it? What else might explain their distress, and how can clinicians help them make sound decisions?

Renewed interest in careful assessment does not, by itself, vindicate every aspect of Zucker’s old approach. In particular, it does not show that therapy can prevent a transgender outcome, or that prevention should be its goal. Zucker is still working on those questions. He has recently written with Michael Bailey about psychotherapy for gender dysphoria and is collaborating with Bailey and Lisa Littman on a study following adolescents and young adults over time.

So was Ken Zucker a clinician punished for asking questions that medicine needed to ask? Or did his clinic cross a line between exploring a child’s distress and trying to determine who that child should become?
