It is a controversial treatment, with the risk of serious side effects, writes Karolinska University Hospital in its new guidelines.

They came into force on the first of May this year and mean that no one under the age of 18 should receive hormone treatment for their gender dysphoria, other than within the framework of clinical studies.  

The hospital management, which has made the decision, tells SVT that the treatment is based on a very weak scientific basis. 

SVT Nyheter has contacted all six clinics in Sweden that offer gender identity investigations to children and young people.

Following Karolinska's message, they are now acting in different ways.  

Linköping is following in Karolinska's footsteps and is waiting to start new hormone treatments until more facts have emerged.

In Uppsala and Lund, the issue is being discussed.

Uppsala has not yet made a decision, but Skåne University Hospital in Lund is now also awaiting more facts:

“In Skåne, we welcome SBU's review and have chosen to wait for the results for guidance on revisions of the care we offer young people with gender dysphoria.

From Skåne, we participate in the national and international conversation on the issue, and have waited for the review result to have a wait-and-see attitude, ”the hospital writes to SVT.

The clinicians in Västra Götaland and Västerbotten continue with the treatments as before. 

- The profession is divided on this issue, says Svante Norgren, Theme Manager at Astrid Lindgren's Children's Hospital 

- Some want to give treatment to young people, while others are worried about the risks it may entail. 

Today, 330 patients are registered with the KID team in Stockholm and are affected by the new guidelines at Karolinska.
