What is Egg Vitrification
and what does it consist of?

Vitrification is a fertility preservation technique that allows a woman’s eggs to be frozen for when she decides to become a mother. This breakthrough in Reproductive Medicine has given women the freedom and opportunity to choose, since it is not always the best time to have a baby.

This delay in childbearing thanks to the vitrification of oocytes allows them to be preserved with the quality they had when they were cryopreserved.

It is important to know that after 35 years of age the quality and quantity of oocytes decreases. Therefore, in our fertility clinics we recommend freezing the eggs before that age and thus we ensure a good quality that guarantees pregnancy at the most appropriate time for the future mother.

Vitrification is a technique for rapid freezing of eggs. With it, they are preserved in liquid nitrogen at a temperature of -196º C, thus maintaining their characteristics at the time they were cryopreserved.

For whom is Vitrification indicated?

This technique is recommended for:

  • Recommended before the age of 35.
  • Young women who wish to become mothers in the future.
  • Endometriosis.
  • Polycystic ovary syndrome.
  • Medication with impact on fertility with chemotherapy or radiotherapy.

How is the Vitrification process?

Here we detail the step by step of the vitrification proccess:

1. First visit to evaluate your case and design the best therapeutic plan: We adapt to your availability and schedule everything to avoid any unnecessary stress in your daily life.

2. Ovarian stimulation: The objective of IVF treatment is to obtain as many eggs as possible. For this, an ovarian stimulation is performed, with the daily administration of hormones through subcutaneous injections, to enhance follicular growth. This first phase usually lasts between 10 and 14 days during which we monitor your ovarian response by ultrasound. Once we observe by ultrasound that the follicles have reached an adequate size, we induce ovulation with a final injection of the hormone bHCG and schedule the date for your ovarian puncture.

3. Ovarian puncture: It is a simple and quick procedure (about 15 minutes) that is performed under light sedation to avoid any discomfort. During the puncture we extract by a slight aspiration follicular fluid containing your follicles where the oocytes that have developed during that cycle. It is performed by transvaginal ultrasound and does not require hospitalization, so recovery is quick and you can resume your normal life.

4. Vitrification of oocytes: After the puncture, the mature eggs obtained are vitrified (frozen). It is a safe process and allows the oocyte quality to be preserved intact. The eggs will remain in maintenance, with no time limit, until you find the ideal moment to embark on the road to motherhood.
