Fertility programs who freeze eggs for Donor Egg Bank USA use the latest assisted reproductive technology available,
called vitrification, for egg freezing. This vitrification technique is
used to freeze all of the donor’s eggs and was perfected in our labs by Michael
Tucker, Ph.D., a renowned embryologist in the field of reproductive
technology. Until recently, egg freezing was done through a slow freeze
methodology and had varying degrees of success.
Using the slow freeze method, ice crystals would
form within the egg and destroy the cell’s structure. Now embryologists
highly skilled in the vitrification technique can greatly minimize the
formation of ice crystals and keep the cell structure intact. As a
result, our technique protocol ensures eggs that have been vitrified
(frozen) are virtually the same as using freshly retrieved eggs.
Donor Egg Bank USA have trained and certified the embryologists in each
of our Partnering Practices on our specific vitrification technique.
Vitrification techniques vary widely among the general field of
fertility practices and as a result, so does the quality and pregnancy
rates. Therefore our Partner Practices complete a quality assurance
process and every cycle performed is reviewed to ensure consistent
standards of quality.
