When people think about fertility, it is often thought of as something to worry about later in life when you’re ready to start having a family.
If you are considering freezing your eggs for later in life there are a few things you need to understand about your body, your eggs, and the optimal time to freeze your eggs for the best possible outcome.
Egg biology: eggs make mistakes
Women are born with a limited supply of eggs that are used up over our reproductive lives. By the time you try to have a baby, the egg you use is exactly as old as you are. Many women are shocked to learn that over the age of 35, most of the eggs that remain in their ovaries have no potential to become a baby. Critical mistakes frequently made by older eggs that cannot be corrected or prevented.
Will I need my frozen eggs: overkill vs enhanced fertility?
The problem with deciding when the right time to freeze your eggs is that in your 20’s and 30s, when you are less likely to consider the procedure, there are many positive aspects to having your eggs frozen. When you wait until you’re over 35, a number of issues can arise, and the chance of having success is less than if you’d used an egg frozen at an earlier stage.
Below are some pros and cons of egg freezing at the different life stages:
The pros and cons of freezing eggs around 20
Excellent egg quality
High egg numbers achievable in a single freezing cycle
Reduced treatment costs compared with freezing later
Many women will have a family without needing to access their security egg bank
Treatments may (in retrospect) have been unnecessary
Freezing eggs around 30
Very good egg quality
High egg numbers achievable in 1-2 cycles
Reduced treatment costs compared with freezing later
By virtue of being single at this time-point, women who freeze eggs are more likely to benefit from having their security egg bank.

 Freezing eggs after 35
Eggs frozen before further profound fertility decline occurs
May be the difference between having a genetic child or not
May allow women to subsequently have a second or third genetic child where this would otherwise have been impossible
Lower egg numbers achievable in 1-2 cycles
More cycles recommended, associated with higher cost for the woman
Reduced egg quality, associated with lower live birth rates per egg warmed
On balance: The best age to freeze eggs is ideally around 30. By this stage, if you haven’t had a baby and are considering egg freezing, it is highly likely that having eggs frozen will enhance your future fertility options.  Beyond 35, while having eggs frozen can still benefit you profoundly, it becomes much harder to achieve ideal egg numbers in a single round of freezing.
