Is egg freezing safe?
To date approximately 150 babies have been born from frozen eggs with no increased rate of birth defects when compared to the general population. Additionally, results from one study showed no increased rates of chromosomal defects between embryos derived from frozen eggs compared to embryos derived from fresh eggs. There have also been over 150,000 children born worldwide from frozen embryos using primarily slow-freeze cryopreservation techniques (the process USC Fertility uses for egg freezing) without an increase in birth defects. Although these data are reassuring, it will take many years of follow-up to ensure that babies born from egg freezing technology have no higher rates of birth defects than those conceived through other means.
