When a couple decides to undergo fertility treatment through the use of donated eggs (egg donation), they can be either fresh or vitrified. At Ovoclinic, we work with both techniques, and following our success rates, we have achieved excellent results in both fresh and delayed transfers. However, we carry out a greater number of transfers with vitrified eggs (previously devitrified and fertilized in the laboratory) because we have Ovobank in our facilities, which allows patients to carry out their egg donation treatment effectively, without waiting lists.
Following the latest statistical report published by the SEF (Spanish Fertility Society), 80% of embryos in 2019 were transferred in the blastocyst stage and delayed, which indicates that cryopreservation techniques could indicate an improvement in the success rate reproductive. Ovoclinic collaborates with Ovobank, the first Egg Bank in Europe, which ensures the highest quality of vitrified oocytes.
ADVANTAGES OF AN OVODONATION CYCLE WITH VITRIFIED EGGS
Next, we are going to outline the most relevant differences of performing an egg donation treatment with vitrified or fresh oocytes.
WIDE SELECTION OF DONORS AND PHENOTYPES
By performing treatment with vitrified EGGS, the patient will have access to a wide pool of donors, of ethnic origin and phenotypes. In the same process with fresh eggs, the selection is generally limited to the number of similar donors available at that time, so the variety of egg donors is limited.
NO WAITING LISTS
Ovobank is located at the Ovoclinic facilities and has a variety of donors to find the one that most closely matches the patient, so there are no waiting lists to start the treatment.
The patient will have immediate availability, which means that she can plan the beginning of the treatment when she wishes and the medical direction advises. With fresh eggs, the patient must synchronize her cycle with the donor and assume different risks that may appear, such as, for example, the cancellation of her stimulation cycle or any problem that directly affects the donor.
The patient will not have to synchronize with the donor to initiate the ovarian stimulation. The eggs are already vitrified and will only have to undergo a devitrification process to be fertilized and transferred.
At Ovoclinic and Ovobank we make sure that the donors are suitable and in good health, carrying out exhaustive medical, genetic, and psychological studies, which guarantees that the eggs are of quality to achieve high pregnancy rates.
A “selfie” TO FIND THE DONOR MOST LIKE THE FUTURE MOTHER
In addition to all the above advantages, with the facial recognition application developed by the Ovobank R & D & i team: Ovomatch, it is possible to analyze various biometric points on the patient’s face and search, among a wide variety of available donors, the one that most closely resembles it physically. The patient only has to take a “selfie” with the mobile and from the app, the algorithm will search for the donor with a greater resemblance.
