A guide to oocyte cryopreservation
Egg freezing can be a highly effective form of fertility preservation, conferring potentially high chances of pregnancy in later reproductive life.
Need to know:
Females are endowed with a finite and non-renewable repository of oocytes: around 1-2 million at birth. As a consequence, with age, the number and quality of oocytes decline. In sharp contrast, in males, postnatal replication of germ line stem cells within the testes produces tens of millions of sperm daily.
