Fig. 1From: Advancements in fertility preservation strategies for pediatric male cancer patients: a review of cryopreservation and transplantation of immature testicular tissueSchematic overview of fertility preservation through cryopreserved, thawed and transplanted ITT. The ITT could be cryopreserved by vitrification or CSF, and then isografted, autografted, or xenografted into species after being thawed. Here were the major milestones in offspring production following these cryopreservation methods. Offspring production was both observed through CSF and vitrification. Researches in this area are currently limited to animal models. LN2, liquid nitrogenBack to article page
