How many eggs need to be frozen?

By Emilio Gómez Sánchez.
Last Update: 11/18/2021

Several studies recommend that the number of oocytes that should be stored is between 20 and 25 if the woman is under 35 years of age. If this age is exceeded, a greater number should be vitrified, since there will be fewer good quality oocytes. Although it should always be made clear to the patient that these cryopreserved oocytes will give her the possibility of performing in vitro fertilization in the future, and that she will have a high possibility of achieving a pregnancy, but this is not 100%.

Once vitrified, the eggs can be stored indefinitely.
