The Donor Egg Bank USA network began shipping egg lots between fertility programs 3 years ago. Our collaboration of fertility practices continues to grow and clients now have the convenience of using frozen donor eggs both nationally and internationally.
The above chart encompasses 2,188 embryo transfers that were completed in all programs. Donor Egg Bank USA requires all of our network programs reports 100% of cycles that are completed within the network. Success rates vary by fertility practice and the above statistics incorporate all of the results regardless of individual fertility practice performance.
Through our experience, we have found 5 mature eggs to be needed to produce embryos sufficient for transfer with a very good success rate. The frozen donor eggs in our network are all mature and egg lots range between 5 - 8 eggs on average. The egg lot size available for each donor can be viewed in the donor database. We believe that when physicians and embryologists share knowledge and resources, patients will have the best opportunity to achieve their dream of having a baby.
We know that egg survival is not indicative of egg quality and therefore we take the additional step of guaranteeing a good quality embryo by day 3. The Donor Egg Bank USA network provides only mature eggs for sperm insemination. If all eggs available in the egg lot are thawed and fertilized, we guarantee at least one or more normal developing embryos will be available for transfer by day 3, unless there is a known male factor which would prevent normal embryo development.
In 54% of egg thaws, sufficient embryos have been available for both a transfer and an embryo freeze. In the unlikely event, that a good embryo is not available by day 3 (and that embryo doesn't convert to a blastocyst by day 6), then clients electing the Single Cycle Financial Plan will be provided a new egg lot and for clients in our Assured Refund Plan, the cycle will not count as one of the 6 attempts.
We offer this assurance not only for your peace of mind but because we are confident in the quality of the donor eggs provided in the network. We also make this assurance available to all programs in the network and not just a select few.
