| Research Abstract |
(Background)Chemotherapy and radiotherapy are essential for treatment of cancer in children and young adults, but these methods often result in testicular failure or reduced ovarian function. One problem in this area is that the ovum is structurally weak, compared with sperm, and the pregnancy rate after frozen ovum storage is very low. Ovarian preservation might be performed before cancer therapy and, in particular, may offer hope for preservation of fertility in young women with cancer.(Method)We hypothesize that this is due to instability of blood flow, and to examine this possibility we have focused on the vascular system and cryopreservation of 5 rats and 2 cynomolgus monkey with MRI whole organ freezing method, magnetic resonance influenced. We are examining the potential of this technology in transplantation and cryopreservation of the ovary.(Result)We attempted transplantation of a vascularized ovary following a certain period of cryopreservation. The endocrine function of the ovary and the potential for pregnancy were permanently re-acquired following these procedure.
