A new long-term study from Germany suggests that the majority of young people diagnosed with gender identity disorders do not continue to identify as such over time. The study examined insurance data over five years, revealing that more than half of young people aged 5-24 across every age subgroup diagnosed with "gender identity disorder" no longer had the diagnosis after five years. Specifically, the desistance rate was 72.7% in 15- to 19-year-old females and 50.3% in 20- to 24-year-old males. Among the whole group of 5- to 24-year-olds, only about 36.4% of those diagnosed in 2017 still had the diagnosis five years later, indicating that more than 63% desisted. 

One of the strengths of this study is its comprehensive collection of outpatient billing data for all legally insured persons in Germany, providing a large and representative sample. Additionally, the long observation period from 2013 to 2022 offers valuable insights into long-term trends and changes in diagnosis rates.

The research also noted a dramatic rise in the number of young people being diagnosed with gender identity disorders. In 2013, there were 22.5 cases per 100,000 insured young people, but by 2022, this had increased to 175.7 cases per 100,000, representing an increase of nearly 681%. The study highlighted that, in almost all years, the highest prevalence of gender identity disorder diagnoses was found in 15- to 19-year-old females. In 2022, this age group had a prevalence rate of 452.6 cases per 100,000.
