Knowledge | Egg Freezing: A New Option for Delaying Parenthood
As society changes, more women are considering their reproductive futures. Egg freezing, an increasingly common medical technology, is becoming an important option for women who want to delay parenthood and preserve fertility. It allows women who hope to become mothers in the future to retain the possibility of using younger eggs when they are ready.
1. The Science of Egg Freezing
Egg freezing relies on a newer technique called vitrification, which prevents the structural damage previously caused by ice formation during freezing and thawing. As Teresa K. Woodruff, PhD, director of fertility preservation in the Department of Obstetrics and Gynecology at Northwestern University Feinberg School of Medicine, explains, vitrification rapidly turns the water-like material in an egg into a solid, avoiding the cracking common with traditional freezing methods.
Because of this advance, the American Society for Reproductive Medicine officially removed the “experimental” designation from egg freezing in 2012. To date, more than 2,000 babies worldwide have been born from frozen eggs, including about 1,000 in the past five years.
2. Success Rates and Costs
Although egg freezing is now well established, age remains an important factor in reproductive success. If a woman freezes her eggs at age 30, her chance of pregnancy per treatment cycle is approximately 13.2%; if she freezes them at age 40, it falls to 8.6%.
The process resembles in vitro fertilization (IVF). Fertility medications first stimulate the ovaries to produce multiple mature eggs in one cycle. A physician then retrieves the eggs in a minor, ultrasound-guided procedure under light anesthesia and freezes them for storage. Frozen eggs can be stored for 10 years or longer.
The procedure can be costly. One freezing cycle typically costs about $10,000, storage costs approximately $500 per year, and thawing and transfer cost about $5,000. IVF itself may cost another $10,000. Most insurance plans do not cover egg freezing, so women generally pay out of pocket and may seek partial reimbursement for medications.
3. Conclusion
Egg freezing gives women more reproductive options and autonomy. For women who wish to delay parenthood, it represents an important advance. Despite the high cost, the technology may preserve the opportunity to build a family at a later time.
