To maximize the chance of having a baby after egg freezing, you may need to go through a series of stimulation cycles to collect a good number of eggs. However, it is important to remember that no number of eggs can guarantee a live birth, as other factors such as egg quality are also relevant. Egg freezing should therefore never be seen as a definitive alternative to natural conception
We provide advice based on scientific tools around exactly how many eggs you need to freeze to find an acceptable cost/benefit situation. Studies based on in vitro fertilization show that if you have 20 eggs, you will have the following probability of succeeding in having a child:
- 35 years or younger, 80-90%
- 37-38 years, 60-70%
- 42 years, 37% (60 eggs, 75%)
