Assisted Reproduction Treatments
Egg freezing, or oocyte vitrification, allows eggs to be preserved for potential use in the future. It may be an option for women who wish to postpone motherhood, patients who are going to undergo treatments that may affect their fertility, or women who want more time to explore their reproductive options.
Before starting the process, the specialist assesses age, ovarian reserve, follicle count and hormone levels. This information helps estimate how many eggs may be retrieved and what expectations are realistic in each case.
It is important to understand that egg freezing does not guarantee a future pregnancy. The chances of success depend on the woman’s age at the time of vitrification, the number and quality of the eggs, their survival after thawing, fertilisation, embryo development and embryo transfer.
Egg Vitrification is an easy, safe and painless treatment. First, eggs must be obtained. This is done through a process of ovarian stimulation, followed by the retrieval of eggs through ovarian puncture.
Once the eggs have been obtained, they are frozen using vitrification techniques. The Vitrification is a type of cellular solidification at low temperatures in a short time, without the formation of ice. To accomplish this, large quantities of cellular cryoprotectants are used to prevent the cell membranes from rupturing, which allows for a high survival rate of cells after thawing.
When the decision is made to attempt pregnancy, the eggs are thawed and then fertilised. The embryos are transferred two or three days later without the patient needing to undergo hormonal treatment.

The main advantages of egg vitrification include fertility preservation, the possibility of planning a future pregnancy without age affecting egg quality, and the flexibility to use frozen eggs when the time is right.
The cost of egg vitrification varies depending on the clinic and country, but generally ranges from €1,000 to €3,000 per cycle. This cost includes ovarian stimulation, egg retrieval, and the freezing process. There are also additional costs for annual egg storage.
While there is no strictly defined age limit, egg vitrification is most effective when performed before age 35, as egg quality and quantity decline with age. Women over 38 can opt for vitrification, but should be aware that success rates may be lower.
The vitrification process itself is not painful, but ovarian stimulation and egg retrieval can cause discomfort similar to premenstrual syndrome. Most women recover quickly after the retrieval and can resume their normal activities the next day.
Vitrified eggs can remain frozen for many years without losing their viability. There is no specific time limit, giving women the flexibility to decide when they wish to use them.
If you decide not to use your vitrified eggs, you have the option to continue storing them, donate them for research or assisted reproduction for other people, or dispose of them according to local regulations and your personal preferences.
Egg vitrification does not significantly affect ovarian reserve. The ovarian stimulation used to obtain the eggs mimics the natural process of follicle selection that would develop in a regular menstrual cycle.
The best time to freeze eggs is before age 35, when egg quality and quantity are optimal. However, every woman is different, and it's recommended to consult a fertility specialist to determine the best time for your individual circumstances.
Yes, vitrified eggs can be used in an in vitro fertilization (IVF) cycle later. Once thawed, the eggs are fertilized in the laboratory, and the resulting embryos are transferred to the uterus to attempt pregnancy.
The process usually includes an initial consultation, hormone tests and ultrasound scans, ovarian stimulation, monitoring and egg retrieval. The exact duration depends on the ovarian response and the recommended protocol.
No. Egg vitrification increases future reproductive options, but it does not guarantee pregnancy. The outcome will depend on several biological factors and on the treatment carried out at a later stage.
