The storage is done for 12 months, and for the chemotherapy, the storage is maintained for around ten years that can even be further extended in few situations.
OOcyte or Eggs Cryopreservation is applicable on females who need to receive a serious medical treatment for severe diseases for example cancer that may terribly decrease their ability to release eggs thereafter. This method is also significant for females who want to focus on their career and want to put their motherhood on hold. In this procedure, the eggs are excessively developed by females that are then frozen within a couple of hours of retrieval and then stored.
