[Practice of Fertility Preservation for Cancer Patients in the AYA Generation].

The adolescent and young adult(AYA)generation is defined as population aged 15 through 39years and is widely used by many organizations and associations. Female fertility preservation consists of oocyte freezing, embryo freezing, ovarian tissue freezing and transplantation, and ovarian protection by the GnRH agonist in anticancer agents. In particular, owing to the characteristics of fertility preservation for cancer patients in the AYA generation, a longer frozen storage period is possible. Special consideration for the devised and informed consent protocol for adolescent patients and psychological support are needed when patients gets older. At the same time, a safer and more effective technology could be developed during the storage period.
