Why freeze your eggs?
Currently, about 70% of 35-year-old women do not have children. This fact leads to a higher challenge in achieving pregnancy because as the age of the woman advances, there is a decrease in the number and quality of oocytes.
For this reason, it is recommended to preserve fertility when there is still an adequate oocyte reserve, preferably before the age of 35 – 38.
Who is it recommended for?
Women who, for personal or other reasons, wish to postpone motherhood.
The transfer is done with a single embryo or a maximum of two. That way we reduce the risk of multiple pregnancies.
Woman of a reproductive age with cancer and who may have decreased reproductive potential.
After undergoing chemotherapy and radiation therapy, a fertility preservation treatment may help them achieve pregnancy once they have overcome the illness.
Women who have had surgery on their ovaries and whose fertility may be compromised.
The Treatment Step by Step
What is the procedure?
This procedure follows the same steps as in an In-Vitro Fertilisation (IVF) cycle: ovarian stimulation with hormones, oocyte aspiration, and instead of inseminating and fertilising them, they undergo vitrification (Cryotop method) before storing them in liquid nitrogen.
The oocytes can be cryopreserved for as long as the patient wants or needs, there is no time limit on this. With the Cryotop technique we have achieved survival rates of up to 97% in young patients (under 35), and pregnancy rates similar to those obtained with fresh oocytes.
The main factor that negatively affects survival rates is maternal age, although the results are similar to those obtained with oocytes before vitrification. No differences have been observed in the birth weights of live born babies when compared to those obtained with fresh oocytes in both single and twin pregnancies.

Oocyte vitrification for patients with cancer
Women with cancer and high life expectancy, regardless of their age, need to preserve their reproductive potential when facing cancer treatment, a potential cause of infertility. For these women, the option to freeze and store their eggs in an egg bank could save their reproductive potential and allow them to become pregnant in the future.
