Egg Freezing6 views

Current medical consensus is that eggs can be stored long term in liquid nitrogen at -196 C, for at least 10 to 15 years or even longer. Studies show that storage duration has no significant effect on egg survival or fertilization rates after thawing. However, as a woman ages, pregnancy success using frozen eggs is still related to the age at which the eggs were frozen. Storage limits vary by country; for example, Taiwan allows storage for up to 10 years, while some countries allow extensions. For exact storage limits and future use rules, consult a reproductive medicine specialist.
