Success Rates

The Donor Egg Bank network began shipping egg lots between fertility programs 5 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.

DEB Success Rates- Oct 2017

The above chart encompasses 4,164 embryo transfers that were completed in all programs. Donor Egg Bank requires all network programs to report 100% of cycles. 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 6 and 7 eggs on average. The egg lot size available for each donor can be viewed in the donor database. Additional eggs chosen increases the likelihood of embryos remaining for another try.  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.

Our Egg Lot Assurance

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 network provides only mature eggs for sperm insemination. We guarantee at least one or more normal developing embryos will be available for transfer by day 3, unless there is a significant known male factor, which would prevent normal embryo development.

In 58% of egg thaws, sufficient embryos have been available for both a transfer and an additional 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 we will provide a new egg lot in accordance with your chosen financial plan. 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.
