our statistics

Our experience indicates that egg freezing and thawing using Frozen Egg Bank’s technique can be routinely performed, yielding good survival and pregnancy success rates.

Our strategy allows us to obtain a 91% survival rate post-thaw; from the 621 eggs that were thawed, with a 54.3% (50/92) pregnancy rate per transfer.


Since 2005, we already have 70 babies born and counting from frozen eggs. This is the highest number of babies born to one clinic in the Western Continental United States. Refer to Graph I.

Egg Freezing Success Rates 2005 - 2008

A number of reports have been nationally published or presented on oocyte cryopreservation. Outcomes of oocyte cryopreservation using the different slow-freeze methods are compared with Frozen Egg Bank’s method. We compared the data from other published authors regarding the survival rate, fertilization rate and the number of oocytes thawed in order to achieve a pregnancy. The Frozen Egg Bank experience is shown in the teal colored bar in Graph II.
