This book is a practical guide to thecryopreservation and transplantation of oocytes, embryos, and ovarian andtesticular tissue for fertility preservation. Illustrated with a wealthof figures and photos, it provides updated techniques for clinicians,technicians, and researchers. This book also gives insights into in vitroactivation (IVA), in vitro growing (IVG), and in vitro maturation (IVM), withboth basic research and future directions. These techniques combined withcryopreservation will improve the chances of reproduction. Cryopreservation isessential to protect fertility in cancer patients who undergo treatment withradioiodine or chemotherapy, which may cause damage to their reproductiveorgans, and also for primary ovarian insufficiency patients. The book alsoincludes a chapter on the risk of the presence of malignant cells in ovariantissue. Both editors are pioneering researchers in this field.
