Based on the articles I've linked to, the summary is that either:Ok. How would you summarise the evidence that puberty blockers aren't effective?
- no statistical improvement in mental health was measured
or
- the studies that claimed to see improvements in mental health are now being called into question because they were poorly designed studies.
== This is just my summary!
And to be clear: The claim under scrutiny is that these hormones improve mental health. No one saying they don't block puberty.
