Ovarian tissue cryopreservation in girls and adolescents at risk of gonadotoxicity: a 15-year experience in 159 patients from a referral program

Freezing ovarian tissue helps preserve fertility in girls with cancer, with this large study showing the approach's real-world success rates.

This 15-year retrospective study of 159 girls and adolescents documents outcomes of a structured risk-based ovarian tissue cryopreservation (OTC) program for pediatric oncology patients, finding primary ovarian insufficiency in 43% of evaluable patients. The study provides a coordinated care model with clear denominator definitions for endocrine outcome tracking across hematologic and other malignancies.

What the study was

Study design
Retrospective observational study (n=159, single center, 15 years)

Sample size
159
Category
Prevention
Maturity
Validated
Journal
Clinical & translational oncology

Why it surfaced

Largest single-center OTC experience in pediatric oncology; directly relevant to hematologic malignancy patients (HSCT, leukemia); addresses vulnerable underserved population.
