Success rates

Not every frozen egg will result in a baby.

When thinking about egg freezing you may like to consider:

  • How many eggs your fertility specialist expects will be collected in a cycle
  • Your ideal number of frozen eggs (possibly over multiple cycles)
  • How likely your frozen eggs are expected to survive the thawing process
  • Your chances of having a baby from each thawed egg
  • The number of egg freezing cycles you can and want to go through
  • The number of children you may want to have using frozen eggs

Chances of egg freezing working

Let’s say you freeze 10 eggs.

If the time comes for you to use your eggs, around (34):

  • 7-8 will survive thawing
  • 5-6 thawed eggs will become embryos
  • 1-2 of those embryos have the potential to become a baby
04 Chances of Egg Freezing Working

This is a general example, and outcomes will be different for everyone. A fertility specialist will be able to give you more personalised advice.

Your chances of having a baby will depend on:

  • Your age when eggs are frozen
  • The number and quality of your frozen eggs
  • Other factors (e.g. quality of the sperm used to fertilise the eggs)

If you would like the option of having more than one child from frozen eggs you may need to freeze more eggs.

Your IVF Success have an egg freezing calculator which may help estimate your own potential success rates. Click here to visit their website.

The only way to know if your frozen eggs will become a baby is to try and use them. If they do not work and you want to continue trying to have a baby, you may be able to use IVF with your own eggs, or donor eggs/ embryos if available.
