Area of Science:
- Medical research
- Surgical procedures
- Endocrinology
Background:
- Gender dysphoria involves a mismatch between biological sex and gender identity.
- Hormonal therapy and gender-affirming surgery are primary treatments.
- Danish gender-affirming surgery is centralized, with limited specialized surgeons.
Purpose of the Study:
- To conduct the first nationwide, single-center review of gender-affirming surgeries in Denmark.
- To analyze trends in patient demographics and surgical procedures.
- To assess changes in the age of patients undergoing gender-affirming surgery over two decades.
Main Methods:
- Retrospective analysis of electronic patient databases from 1994 to 2015.
- Inclusion of patients diagnosed with gender identity disorders.
- Exclusion of individuals with pseudohermaphroditism or unreported gender.
Main Results:
- 158 patients were included: 65% female-to-male (FtM) and 35% male-to-female (MtF).
- Total surgeries: 126, including 62 FtM mastectomies and 45 MtF vaginoplasties.
- Median age at surgery decreased significantly from 40 to 27 years over the study period.
Conclusions:
- Gender-affirming surgery rates showed a higher prevalence in FtM individuals.
- A notable decline in the age of patients seeking gender-affirming surgery was observed.
