Press Release Infertility: Pregnancy from Frozen Human Egg in Connecticut


Pregnancy from Frozen Human Egg, 
Reported by New England Fertility Institute 
of Stamford and Hamden Connecticucut.



Dr. Gad Lavy M.D., F.A.C.O.G., Medical Director and Founder of the New England Fertility Institute announces a pregnancy resulting from a frozen human egg. “To our knowledge this is the first human pregnancy achieved in Connecticut from a frozen egg.”


To date, there have been only about 300 births resulting from frozen eggs worldwide. Human eggs are far more difficult to successfully freeze and thaw than embryos. The is in part due to the large water content of the egg that results in the formation of ice crystals on freezing.  Ice crystal formation within the egg can cause damage or destruction of the egg. Better understanding of the egg cell and improved cryopreservation procedures have led to successful freezing and thawing of human eggs.


Our team was able to freeze the eggs of a 25 year old donor for 6 months and then use standard IVF procedures to achieve a pregnancy in a recipient.  The pregnancy is ongoing and seems to be progressing normally

“We have crossed a significant clinical threshold with regards to successfully freezing and thawing egg”, said Dr. Ervin Jones PhD., M.D., Associate Medical Director of the New England Fertility Institute.


The potential applications for egg freezing are far reaching and include:
1. Freezing eggs of single women who are diagnosed with cancer and are about to have surgery or chemotherapy, which is likely to damage ovaries.
2.  Freezing the eggs of single women are concerned about the effects of aging on the quality of their eggs and their chances of achieving successful pregnancy.
3. Creating donor egg banks similar to sperm banks. Providing couples in need of egg donor a wider choice, and simplifying the procedure.
4. Limiting the number of embryos created during standard IVF.

We have stored frozen eggs from women with cancer and from women concerned about the effects of aging on their eggs.
