**5. Conclusions**

In conclusion, many factors affect the successful application of oocyte cryopreservation for women who want to preserve their fertility. Women's age at the time of oocyte cryopreservation is one of the most important factors to consider. Based on our current and previously published data, we can conclude that oocyte cryopreservation for fertility preservation can be done at any time during a woman's reproductive age. Similar as fresh oocyte IVF, the overall efficiency of oocyte cryopreservation is dependent up on women's age and reproductive health at the time of oocyte cryopreservation.
