Success Rates

The Donor Egg Bank USA network began shipping egg lots between Fertility programs more than two 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. 

Using our multi-site data from 3/1/2012 to 3/31/2014, 786 egg lots have been thawed which produced a pregnancy rate of 60% (includes biochemical pregnancies), a clinical pregnancy rate of  52% (a gestational sac was seen on ultrasound), and an on-going pregnancy rate/live birth rate of 45% per transfer (after miscarriages) .  Presently we are achieving a 47% on-going pregnancy/live birth rate per egg lot selected.   Network programs are using on average 1.6 embryos for each transfer.  Thirty eight percent (38%) of cycles have resulted in additional embryos to freeze beyond the initial transfer.  

More than 60% of egg lots thawed through the Donor Egg Bank USA network have resulted in a pregnancy and 45% resulted in an on-going pregnancy or the birth of a baby.

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 n our network are all mature and egg lots range between 5 and 7 eggs on average.  The egg lot size available for each donor can be viewed in the donor database. We believe that when physicians and embryologist share knowledge and resources, patients will have the best opportunity to achieve their dream of having a baby.

Our Egg Lot Assurance

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.  In 38% of egg thaws, sufficient embryos have been available for both a transfer and a cyro quality embryo freeze.  In the unlikely event, that an embryo is not available by day 3, 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.
