There are many advantages to obtaining eggs from an egg bank. The donor has been fully screened and the eggs are already frozen. The cost of obtaining eggs from an egg bank are also less than doing a fresh donor cycle. However, the success rates using eggs from an egg bank are lower than doing a fresh donor cycle. In addition, you receive a limited number of eggs. This greatly reduces the chances of having extra frozen embryos if the first transfer is not successful or for a second pregnancy. Also, the chance that you will be able to have a genetic sibling are drastically diminished.
