The process of vitrification of ovules consists in reducing the temperature at which the oocyte is exposed, immersing it in liquid nitrogen at -196 ° C. Due to its high cooling rate, the formation of ice crystals is avoided, which are the cause of damaging the oocyte by damaging the cellular structures.
In Spain, the birth of many children has already been achieved with this procedure, which offers pregnancy rates similar to those obtained with fresh oocytes.
2. Who can benefit from oocytes vitrification?
Any woman who wants to delay her motherhood for professional or personal reasons.
Cancer patients who will receive radiotherapy or chemotherapy treatments, which can cause irreversible damage to the oocytes.

Phases of oocytes vitrification treatment
The process of vitrification of ovules to achieve the preservation of maternity involves three phases
1. Ovarian Stimulation
Through the administration of hormonal medications, and always under the supervision of the Oyala Gynecology and Fertility Center professionals.
2. Extraction of oocytes
Through a simple intervention called follicular puncture. It is a painless and rapid intervention.
3. Vitrification of oocytes
Once the ovules are removed, the vitrification of oocytes is performed in the laboratory. After this process, your ovules remain preserved in liquid nitrogen and perfectly identified for an indefinite time.
At the moment you decide to use the oocytes, they are devitrified to fertilize them with the sperm of the couple or an anonymous donor. Subsequently, embryos are introduced into the maternal uterus, using the Intracitoplasmic Sperm Injection (ICSI) technique.
