If you can feel the clock ticking but you want to postpone motherhood, AGE banking may be a solution. This is also known as social freezing.
During your ART treatment or before you start treatment, it may be necessary to freeze and store reproductive cells or tissue. UZ Brussel's tissue bank where we store reproductive human tissue is called the CRG's MLM bank.To freeze any tissues, a contract must be signed at all times. In this contract:
These decisions can be revoked at all times, as long as you do this in writing before the end of the storage period.

Egg retrieval for postponed use: AGE banking or social freezing?
The CRG prefers to talk about AGE banking rather than social (egg) freezing.
AGE stands for Anticipation of Gamete Exhaustion and (very precisely) refers to the purpose of the intervention: you want to freeze your eggs (gametes) before they are exhausted.
However, the word AGE also stands for the most important female factor in terms of fertility: your age.
Nevertheless, the less accurate term social freezing is pretty much established, which is why we also use it sometimes.
In the contract you concluded with the CRG, the procedure you will have for AGE banking is called ‘egg retrieval for postponed use’.
Men are able to create new sperm until very late in life. Women on the other hand are born with a specific number of eggs, the number of which only decreases with the years. No new ones are created. Furthermore, with age the quality of the remaining supply diminishes, particularly by the relative increase in the number of eggs with a chromosomal abnormality. See also A woman's age
But even if you are aware of this biological clock, you may still have good reason to want to postpone motherhood. The frozen storage of eggs can help you to ensure you can have children in the future with your genetic material.
What does the treatment imply?
- Contact the CRG Contact centre and make an appointment.
- You have a consultation with a CRG doctor and a CRG psychologist. They will examine you, evaluate your application and provide all the necessary information, so that you can make a sound decision.
- If you have decided on AGE banking, your treatment is like an ‘ordinary’ IVF cycle (until the egg retrieval):
- In the lab the ripe eggs are immediately frozen and stored, i.e. frozen by vitrification and stored in the egg bank.
Is AGE banking possible at any age?
The considerable influence of your age on your fertility, also applies for AGE banking. The chances of a child after fertilisation of thawed eggs is greater if you are younger when your eggs are collected and frozen.
- At UZ Brussel CRG, eggs can be frozen up to the age of 40. But from the age of 36 (age of frozen storage) the chances of a child reduce considerably.
- Frozen eggs can be stored for ten years or until the age of 47 (the day before your 48th birthday).
- There are no indications that your age at the time the eggs are thawed and fertilised – with the sperm of your partner or a donor – affect the chances of success of your treatment.
But with getting older and certainly after the age of 40, the chances of pregnancy complications increase. This includes pregnancy hypertension (high blood pressure) and pre-eclampsia. .
Is AGE banking safe?
The frozen storage of eggs has become possible since the introduction of the vitrification technique (‘flash freezing’). This technique has already been applied for ten years and has outgrown the experimental stage.
It is a fact that on average 20 to 25% of the eggs do not survive the thawing process after frozen storage. However, investigation into the safety of egg vitrification has shown reassuring results, also and chiefly concerning the effect on the health of children born from fertilised eggs that were frozen.
How much does the treatment cost?

For more information about the (costs of the) treatment or for an appointment, please contact the CRG Contact centre, by telephone or e- mail.
- For AGE banking, i.e. the hormone treatment followed by egg retrieval and the frozen storage of the ripe eggs for maximum ten years (or to the day before your 48th birthday) the CRG charges a fixed amount. This is all for your account, even if you have Belgian health insurance.
- When the eggs are thawed at a later stage and fertilised in the laboratory, the IVF laboratory costs of a patient with Belgian health insurance are reimbursed by the RIZIV, provided you are younger than 43. (i.e. to the day before your 43th birthday). See Age limits.
- If you are no longer entitled (any more) to reimbursement by the RIZIV or if you do not have Belgian health insurance, the second part of the treatment is for your account.
