Genital gender-affirming surgery trends in Germany: Total population data with 19,600 cases from 2006 to 2022

To delineate the current trends regarding gender-affirming surgeries (GAS) in Germany.

Analysis of German hospital quality reports from 2006 to 2022 was conducted using the reimbursement.info tool. The German procedure classification (OPS) codes 5-646.0 for masculinizing- and 5-646.1 for feminizing surgery were assessed to identify GAS. Linear regression models were utilized for the analysis and depiction of current trends.

A total of 19,632 gender-affirming procedures were performed during the study period with an exponential increase over the years. Masculinizing surgeries increased from 246 in 2006 to 1291 cases in 2022 (increase by 424%; p < 0.001). The highest annual increase of 37.2% in numbers was from 2018 to 2019 (from 1235 to 1694 cases). Feminizing surgeries increased from 180 cases in 2006 to 799 procedures in 2022 (increase by 343%; p < 0.001). The cases increased most between 2015 and 2016 from 277 to 502 cases (81.2%). The number of hospitals offering these surgeries expanded from 24 in 2006 to 29 in 2022 (21% increase; p < 0.001).

This study demonstrates an exponential growth in numbers feminizing and masculinizing of GAS performed each year in Germany. Furthermore, a discernible trend emerges with a propensity for concentration of procedures within selected high-caseload centers across Germany.
