Social freezing (oocyte freezing for later use)
Oocyte freezing is a relatively young method as the earlier procedures, unlike current methodologies, did not reach satisfactory results after thawing the oocytes. This method is intended primarily for women without a partner because we always recommend to freeze the already fertilized eggs, i.e. embryos.
Another reason for oocyte freezing can be a cancer disease when a woman undergoes chemotherapy or radiotherapy and there is a risk that the oncology treatment will also "destroy" her eggs. Sometimes we have to freeze the oocytes at the time when a partner fails to "deliver" the sperm for fertilisation in the IVF+ET programme.
Nowadays, however, the dominant reason for oocyte freezing is so-called social freezing. For many reasons, many women now decide to have a baby in their 40s. It is generally known that the ability to conceive decreases with age. Only about 20% women get pregnant without any problems in their 40s. In order to give a woman at this age a chance to have her biological child, it is possible to freeze her eggs in her “reproductive youth” and use them later in the IVF+ET programme.
For this method to be successful, it is necessary to freeze eggs up to the age of 35, ideally up to the age of 30.
