  • Whether you want to freeze raw eggs or a leftover quiche, you may have wondered what happens to eggs when they freeze, or if it's safe to freeze them at all.

The article from MSN discusses the process and effects of freezing eggs, a method increasingly used for fertility preservation. When eggs are frozen, they undergo a process called cryopreservation where they are cooled to sub-zero temperatures to halt biological activity. This involves several steps: first, women undergo hormone treatments to stimulate their ovaries to produce multiple eggs. These eggs are then retrieved through a minor surgical procedure. The eggs are quickly frozen using a technique known as vitrification, which prevents the formation of ice crystals that could damage the eggs. The article explains that while freezing eggs can preserve fertility, not all eggs survive the thawing process, and the success rate of achieving a pregnancy from frozen eggs decreases with the woman's age at the time of freezing due to potential chromosomal abnormalities. It also touches on the costs, the emotional considerations, and the advancements in technology that have improved the survival rates of eggs post-thaw, offering hope for future fertility.
