Egg Freezing

Egg freezing is one of the fastest growing area of fertility services which allows women to preserve their fertility. At iTrust Fertility Centres we can support you to extend or preserve your fertility period through egg freezing. Babies born through the freeze-thaw process are healthy, and success rates are high.

How Does Egg Freezing Work?

The egg freezing treatment process begins with a course of injections to stimulate the ovaries so several eggs can be collected, followed by the egg collection procedure. The collected eggs are then fast-frozen using a technique called vitrification. Anyone considering egg freezing should be aware of the ten year storage limit set by the Human Fertilisation and Embryology Authority.
If and when you decide to attempt a pregnancy using your frozen eggs in the future, they will be thawed and fertilised in the laboratory, with the resulting embryo placed into the uterus.

Success rates

Egg freezing is still a relatively new procedure and the number of women coming back to thaw their frozen eggs is small. Success rates for these women are good, although success depends on the woman’s age and the quality of the thawed eggs.

Egg Freezing vs. Embryo Freezing

Freezing embryos rather than unfertilized eggs improves the chances of a successful pregnancy. Embryos have been frozen for longer than unfertilised eggs, and the procedure has been improved over a longer period; the success rate for unfertilised frozen eggs is around half of the success rate for frozen embryos. However, these rates continue to improve as new techniques are discovered.
