Fresh Vs Frozen eggs
We offer you the option between a fresh and frozen donor egg cycle. For a fresh cycle, eggs are retrieved from the donor after she has completed her IVF cycle and immediately fertilised with the male partner’s sperm.
With a Frozen Egg cycle the mature (M2) eggs are retrieved and then immediately frozen using the very latest Vitrification technology and then stored in our egg bank ready for purchase by intending parents. The initial process is very similar between the two methods.
The Choice is Yours
Although there are very few drawbacks to frozen eggs, there are still many people who prefer to use the fresh egg process. This option requires that you and your donor synchronize menstrual cycles, meaning it could take two or three months before egg retrieval takes place. There is also a small degree of uncertainty regarding whether the donor will have an optimal response to IVF medication during that particular cycle.
The primary benefit of fresh egg donation is that it can provide a greater number of frozen embryos for future procedures- such as genetic screening (NGS) of the embryos to identify potential chromosome abnormalities or select a desired gender.
Research has shown that the success rates for fresh or frozen eggs are very similar. Many people choose to use frozen eggs as the process is simpler than a fresh cycle. Additionally, since frozen eggs are waiting for you to use them, you have greater control over when to begin your donor cycle.
Frozen Donor Eggs Vs Fresh Donor Eggs Statistics
According to the American Society for Reproductive Medicine, the foremost authority in the world in reproductive medicine, recent studies suggest the following comparison between frozen (vitrified) and fresh donor eggs used in IVF:
- 74.2% of frozen eggs vs 73.3% of fresh eggs successfully fertilize;
- 39.9% implantation rate with frozen eggs vs 40.9% implantation rate with fresh eggs;
- 55.4% pregnancy rate with frozen eggs vs 55.6% pregnancy rate with fresh eggs used in donor cycles;
Egg Banks like ours are rapidly changing the egg donation landscape from the use of fresh donor eggs to frozen donor eggs.
The Egg Bank Advantage:
- Simpler treatment
- Synchronization of cycles is not necessary
- More control over schedule
