Abstract
In the fertility preservation programs, ovarian cryopreservation is usually offered when the risk of premature ovarian failure is high (>30-50%) while the risk of ovarian metastasis is low. According to the guidelines, it must be done before the patient receives chemotherapy. A 22-year-old girl with acute lymphocytic leukemia was a candidate for ovarian cryopreservation after 6 months of chemotherapy. Despite chemotherapy, the anti-Mullerian hormone survey was within normal range. Ovarian tissue cryopreservation was done. In the histology survey, follicular density was 7.48. This case shows that only having a history of chemotherapy does not exclude the patient from the fertility preservation program. Regarding referring the patients for fertility preservation, cumulative factors such as a history of gonadotoxic treatment, age, and treatment protocol should be considered. In addition, the case was negative for assessing of CD45 marker. New data may challenge previous strict criteria, and extend the indications of this effective method in preserving fertility among cancer patients.
