The choice of freezing eggs is usually selected in the following cases:
If the woman is suffering from cancer and needs to undergo treatment with chemotherapy, the solution of egg freezing is essential in order to maintain the future chances of having a child. As we know, these treatments are detrimental to the reproductive capacity of women. Thus, the cryopreservation of oocytes prior to treatment gives women the opportunity to have their own children by using their own eggs.
Sometimes, women do not prefer the cryopreservation of embryos for ethical reasons. In these cases, the freezing of mature gametes could serve as an alternative solution.
Finally, many women wish to preserve their future ability to have children either because they have not yet selected a companion or due to business and medical reasons.
In recent years, great strides have been achieved in the history of cryobiology with the cryopreservation of oocytes being one of the objectives that have been achieved. Pregnancies with cryopreserved oocytes have already been recorded, but the percentage is still too low for the method to be considered as a routine method in IVF medical units.
The improvement of cryopreservative materials and freezing protocols in the years to follow will give many women the opportunity to acquire children at an advanced age when it is deemed necessary.
