Egg freezing involves collecting eggs at an age of prime fertility, and preserving them for later use. With the right techniques, eggs can be stored for years without any significant deterioration, giving you the option to use them to achieve pregnancy in the future. When the time is right, stored eggs can be fertilised, and the embryo transferred into your body to increase the likelihood of a successful pregnancy. However, stored eggs do not have to be fertilised. Egg freezing provides women with greater opportunity; it doesn’t force a decision.
