Objectives: To determine trends in clinical practice for individuals with DSD requiring gonadectomy.

Design: Retrospective cohort study.

Methods: Information regarding age at gonadectomy according to diagnosis; reported sex; time of presentation to specialist center; and location of center from cases reported to the International DSD Registry and who were over 16 years old in January 2019.

Results: Data regarding gonadectomy were available in 668 (88%) individuals from 44 centers. Of these, 248 (37%) (median age (range) 24 (17, 75) years) were male and 420 (63%) (median age (range) 26 (16, 86) years) were female. Gonadectomy was reported from 36 centers in 351/668 cases (53%). Females were more likely to undergo gonadectomy (n=311, p<0.0001). The indication for gonadectomy was reported in 268 (76%). The most common indication was mitigation of tumour risk in 172 (64%). Variations in the practice of gonadectomy were observed; of the 351 cases from 36 centers, 17 (5%) at 9 centers had undergone gonadectomy before their first presentation to the specialist center. Median age at gonadectomy of cases from high income countries and low/middle income countries (LMIC) was 13.0 yrs (0.1, 68) years and 16.5 yrs (1, 28), respectively (p<0.0001) with the likelihood of long-term retention of gonads being higher in LMIC countries.

Conclusions: The likelihood of gonadectomy depends on the underlying diagnosis, sex of rearing and the geographical setting. Clinical benchmarks, which can be studied across all forms of DSD will allow a better understanding of the variation in the practice of gonadectomy.
