Success Rates

Donor Egg Bank USA began shipping egg lots between fertility programs in 2012.  Following our merger with California Cryobank in 2016, the network has grown to over 150 fertility practices, and clients have the convenience of using frozen donor eggs both nationally and internationally.

The above chart encompasses embryo transfers that were completed in all programs. Unique to other egg banks, California Cryobank's Donor Egg Bank requires network programs to report 100% of cycles. Success rates vary by fertility practice, and the above statistics incorporate all results regardless of individual fertility practice performance.

We only ship eggs that are mature and capable of producing a baby.  Our egg lots range in size from 5 to 8, with the average size being 6 and 7 eggs.  Because no woman produces mature eggs in perfect groups of 6 or 8, we want embryologist to not be tempted to freeze immature eggs in order to have egg lots all of one size.  The number of eggs available for selection on each donor can be viewed in the donor database. While one egg lot is a good chance at having a baby, egg lots greater than 5 have an increased likelihood of embryos remaining for an additional try. Sometimes we will consolidate two egg lots together and in these cases, the egg lot should perform similar to an egg lot of 6 eggs. 

Our unique network encourages camaraderie and the sharing of expertise and best practices. 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 Guarantee

As the nation's premier egg bank, we offer a blastocyst guarantee. 

Human biology can be unpredictable and we can offer this guarantee because we are confident in the quality of the donor eggs we provide. 

We know that egg survival is not the best indicator of egg quality and therefore we take the additional step of guaranteeing a usable quality blastocyst at nearly every program. Donor Egg Bank USA and California Cryobank provide only mature eggs. We guarantee at least one or more blastocyst will be available for transfer or freezing on or by day 6.  If a blastocyst is not available and a transfer occurs, our obligation has been fulfilled and we will not provide a replacement.  In addition, we require at least one million motile sperm for the guarantee to be in place. 

In 68% of egg thaws, sufficient embryos have been available for both a transfer and additional embryos frozen.  In the unlikely event, that a blastocyst is not available, 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.

This guarantee is designed to give you peace of mind and provide confidence in your investment.
