Egg Freezing6 views

The survival rate after thawing frozen eggs is about 80% to 90%, but fertilization rate, blastocyst formation rate, and live birth rate decline with the woman's age at freezing. For example, eggs frozen before age 35 have an estimated live birth rate of about 4% to 8% per egg, while rates are significantly lower after age 38. Success also depends on whether preimplantation genetic testing (PGT) is performed after thawing and on the condition of the uterine lining. Egg freezing cannot guarantee future pregnancy, and each thaw cycle usually requires multiple eggs. Individual success estimates should consider age, ovarian function, and other factors, so consult a reproductive medicine specialist.
