Female patients decide to freeze their eggs for a variety of reasons. In many cases, it's for fertility preservation before a medical treatment damages ovarian reserve. Women who've been diagnosed with cancer may choose to freeze their eggs before receiving treatment. Chemotherapy and other medications can have a devastating impact on a woman's ability to produce viable eggs. In many cases, her eggs can be irreversibly damaged or destroyed. In other instances, women freeze their eggs to delay childbearing to a more convenient time in their lives.
Cryopreservation preserves the eggs at a temperature that extends their viability for very extended periods. That allows a patient or a parent of a female child to preserve their eggs for use at a time when they're healthy enough to become pregnant and bear a child.
Cryopreservation allows Dr. Oktay to store eggs almost indefinitely. Because he preserves eggs at low temperatures, there’s no tissue deterioration, even over the course of decades. Eggs must be kept in a secure and stable environment where there’s no fluctuation in temperature, to prevent any adverse effects on their viability.
The number of eggs that you should preserve to increase chance of success isn’t concrete or easily determined. However, this depends on many factors, including your age and number of eggs frozen. Because of this uncertainty, Dr. Oktay performed the largest and only study that determines abe-based success rates for egg freezing and came up with an egg freezing success rate calculator. This calculator is being used by thousands of experts and patients around the world. You can find it here.
The Egg Freezing Success Calculator allows Dr. Oktay to determine the best possible success rate for three scenarios. They include:
The calculator estimates the probability that a viable pregnancy will result from the use of eggs that have been cryopreserved based on your age at freezing, the number of eggs you have frozen, and the method used for egg freezing. You can test the formula here. The Egg Freezing Success Calculator is used around the world to help patients determine how many eggs should be frozen, and how many are likely to survive the thawing process. Patients who are interested in learning more about the calculator, and the possibility of storing their eggs, should contact Dr. Oktay for a consultation.
