Objective: To determine if removing an ovary for ovarian tissue cryopreservation (OTC) increased rates of primary ovarian insufficiency (POI) in girls undergoing bone marrow transplantation (BMT). Institutional review board approval was obtained from all 3 clinical sites.
Design: Multicenter retrospective cohort study SETTING: Academic children's hospitals PATIENTS: Females aged 2-21 who underwent BMT with or without OTC from 2010 to 2017.
Interventions: None MAIN OUTCOME MEASURES: Rates of POI in girls who underwent OTC vs those who underwent BMT alone as determined by serum markers, presence of menses, or clinical diagnosis.
Results: A total of 142 patients were identified, 43 who had OTC and 99 with BMT alone. The rate of POI in girls undergoing OTC was 65% vs 41.8% in those who underwent BMT alone (P = .26).
Conclusions: Although this study was not powered to detect a lack of difference, it is reassuring that there does not seem to be a clinically significant increase in POI in patients undergoing OTC.
