Abstract
Today, women's infertility is considered a social disease in females, occurring not only as an effect of POF (premature ovarian failure) but also as CTRI (cancer treatment-related infertility) in oncologic patients. Several procedures for FP (fertility preservation) are currently adopted to prevent this condition, mostly based on utilization of retrieved eggs from the patients with subsequent IVF (in vitro fertilization) or cryopreservation. However, great interest has recently been devoted to OSCs (ovarian stem cells), whose isolation from female ovaries, followed by their in vitro culture, led to their maturation to OLCs (oocyte-like cells), namely, neo-oocytes comparable to viable eggs suitable for IVF. Translation of these data to FP clinical application creates new hope in the treatment of infertility. Thus, in line with the significant progress in using stem cells in the regenerative medicine field, neo-oogenesis via OSCs, which is currently unapplicable in fertility preservation procedures, will provide novel possibilities for young and adult females in motherhood programs in the future.
