A Swedish hospital has stopped prescribing puberty blockers and cross-sex hormones for minors under the age of 16. The Karolinska Hospital in Sweden issued the new policy statement, effective from April 2021. Hormones will still be permissible for 16−18-year-olds under very strict conditions. Approval will only be given in research settings where the review board is satisfied the minor understands the “significant risks and uncertainties of hormonal interventions”. They will determine whether or not the teenager is mature enough, and able to provide true consent, as a result.
