Egg freezing is a way that some women preserve their fertility in hopes of one day successfully bearing a child. Every woman is born with a finite amount of eggs. You will never make more eggs. While you may be born with about two million eggs (or oocytes), by puberty that number is down to 400,000 or so.
Before girls begin menstruating, they lose about 11,000 eggs a month. This number continues to diminish on a monthly basis throughout a woman’s adult life. According to experts at Yale Medicine, a rapid decline begins around the age of 37 and continues until menopause, at which a point a woman may only have about 1,000 eggs left.
There are numerous aspects of a woman’s egg supply and quality that relate to fertility.
There are insufficient tests that measure the quality of eggs in a woman’s body. Scientists and fertility researchers have, however, created a fairly standardized system of harvesting and preserving eggs that could produce viable pregnancies.
History of Egg Freezing
There is an interesting history to egg freezing. While relatively new, its popularity has skyrocketed as a viable way for women to extend their fertility or ensure motherhood “at a later date.” These practices have helped countless women. Here are the high points of cryopreservation and egg freezing practices among women in the United States.
