Objectives We aim to discuss the hematological cancer cases that opted for ovarian tissue cryopreservation (OTC) as fertility preservation before the gonadotoxic chemotherapy agent. Case presentation The ovarian tissue cryopreservation (OTC) was started in August 2020 in our center. Up to now, there were four cases have been performed and included in this report. The ovarian tissue cortex was cryopreserved with cryoprotectant using Kitazato™ (Tokyo, Japan) media and fit in the closed system devices. A total of four post-OTC patients were included. The mean age was 24 years old, whereas the mean serum AMH level was 30.43 pmol/L. Most of them were diagnosed with lymphoma, except one was leukemia. All of them received additional GnRH analog following OTC as a chemoprotective agent before cancer treatment. Currently, they are recovering well and on regular follow-up with the hematological department. Conclusions Although The OTC is an ultimate option for prepubertal girls, it can be proposed as a good strategy for adult cancer women who could not delay cancer therapy.
