Egg Freezing

We can store your eggs, so they are ready when you are.

There are many reasons to delay pregnancy. Elective egg freezing can give you more options so that you can decide when to start your family. As we age, the quantity and quality of our eggs diminish, and as a result, our biological clock does not always fit in with our life plans. Collecting and freezing eggs at an optimum time helps to increase the chance of a successful pregnancy in the future.

When is the best time to freeze my eggs?

The earlier you freeze your eggs, the better your chance of achieving a successful pregnancy – regardless of when you decide to use them. While your ovaries continue to age and the number of viable eggs decline, your uterus remains capable of supporting a pregnancy until about age 50.

Your chance of success is closely linked with the age at which you decide to undergo egg freezing. The optimum time to freeze your eggs is when you have the best ovarian reserve, typically between the ages of 25 and 37. Egg freezing after 37 is still an option; however, you may require multiple rounds of treatment to improve your chances of success. Your fertility doctor will make recommendations as to the number of eggs you should consider storing depending on your age and the plans you have for your family.

How are my eggs stored?

On the day of collection, your eggs are snap frozen using a process called vitrification. This process is highly successful, with at least 95% or more of the eggs surviving the thaw. Your eggs are securely stored in specialised tanks under liquid nitrogen, which ensures they remain at a consistently cold temperature. Our storage tanks undergo 24-hour electronic temperature monitoring and are located in a secure and alarmed area only accessible by our embryology team.

How long can eggs stay in storage?

Eggs can generally be kept in storage for up to 15 years (this time can be extended in special circumstances), provided you continue to pay the annual storage fee. During this time, we send out an annual storage letter to ensure we continue to honour your wishes and inform you as to when the storage time limit is approaching.

What if I no longer need my eggs?

If you want to discontinue the storage of your eggs, a discard form will need to be signed by you. Donation of eggs can be considered in some cases; however, this requires multiple counselling sessions and thorough consideration in order to explore the topics around donation.
