Abigail Shrier's recent book Irreversible Damage explores this question. I highly recommend it.

As I mentioned in another comment:

Abigail Shrier is a writer and not a scientist, and it can be clearly seen even from the title of the book that she has an agenda. The thesis of the book has been "rejected by the American Psychiatric Association, the American Academy of Pediatrics, the Endocrine Society, the American Academy of Child and Adolescent Psychiatry, and the World Professional Association for Transgender Health."

If you have a peer-reviewed study, that would be much more worthwhile to look at.

As I mentioned in another comment, multiple studies have been done. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6095578/

There is severe hesitation to fund this research by the psychiatric and medical establishment.
