N2 - Some women suffering from leukemia require bone marrow transplantation to be cured. Bone marrow transplantation is associated with a high risk of sterility and some patients are offered fertility preservation by cryopreservation of ovarian cortex. Transplantation of ovarian cortex to women cured of leukemia, who became menopausal, is currently not performed due to the risk of introducing the disease. In this study, individual pieces of ovarian cortex intended for reimplantation from 25 patients with leukemia were transplanted to each of 25 nude mice for 20 weeks.
