A Quick Guide to Egg Freezing

Ethnic Couple (4).jpgThe prospect of infertility causes stress and anxiety to most women planning to delay motherhood. Every woman’s quality ovarian reserve declines with age – most precipitously after the age of 37. Freezing one’s eggs at a young age allows a woman to choose the optimum time to conceive later in life – coupled with all of the health benefits derived from using her quality eggs.

Benefits of Egg Freezing

By 2018, an estimated 76,000 women in the United States will freeze their eggs to preserve their future fertility. This fertility preservation method will increase the odds of these women conceiving later in life at a time of they choose to start building their family. New Hope Fertility Center’s Division of Fertility Preservation has compiled an easy guide help women to learn more about the benefits of egg freezing. Egg freezing is becoming the preferred fertility preservation option women are choosing today because it avoids the future anticipated cost and physical challenges of multiple IVF cycles.

Best Age to Freeze Eggs

The best age for a woman to freeze her eggs is between 32 and 36. Any woman between the age of 30 and 40 who is planning on delaying motherhood should consider egg freezing. The number of eggs a woman will need to build her desired family is dependent upon her age, however, not every woman has the same egg reserve. Women who elect to freeze their egg when they are under 40 have the best chance of conceiving a pregnancy from their frozen eggs over 40. Bottom Line: Egg freezing success rates are most cost-effective when a women freezes her eggs under by the age of 38.

IVF – Egg Freezing

Through In Vitro Fertilization (IVF) a woman’s natural egg production is stimulated with fertility drugs into producing several eggs – 10 to 15 typically per cycle. These eggs are then surgically retrieved and cryopreserved using an advanced technique known as vitrification.

Vitrification Method of Freezing Eggs

New Hope Fertility Center’s founder and medical director – Dr. John Zhang – pioneered the modern egg freezing method of vitrification. Used by our fertility specialists since 2004, vitrification is an advanced technique designed to increase the chance of a woman’s eggs surviving. There are three stages of cryopreservation that an egg must survive in order to increase a woman’s chance of pregnancy in the future:

  • Freezing
  • Thawing
  • Fertilization

Vitrification is the rapid freeze method of freezing eggs. Extreme, rapid freezing avoids the formation of harmful ice crystals between an egg’s cells.

To prepare an egg for rapid freezing:

  • The eggs are placed in a high concentration of cryoprotectant solution while at room temperature
  • The eggs are then directly plunged into liquid nitrogen to immediately drop the temperature in a large number of degrees
  • An extreme rapid rate of thawing is used to prevent ice crystal damages prior to fertilization of the eggs with sperm in vitro

Recent studies have shown that vitrification increases the chance for survival of the egg when it is thawed and fertilized.
