Clinical Reproductive Trial Shows Major Advances in Fertility Options Yielding Successful Pregnancies Using New Vitrification Technique

Acclaimed fertility specialist and leading expert in the field of reproductive medicine Dr. John Jain, MD, FACOG announced today that he is conducting new clinical trials of egg freezing technology at Santa Monica Fertility Specialists (SMFS) and Egg Freezing Center (EFC). Dr. Jain’s study is the first in the United States to compare the two most promising methods of egg freezing—the more established slow-freeze method and a newer flash-freeze technique known as vitrification.
Preliminary reproductive results are especially encouraging for the vitrification technique with six pregnancies already established, including the first triplet pregnancy from this FDA approved trial.
While the slow-freeze method has already yielded positive results at EFC, the formation of intracellular ice crystals has traditionally presented certain obstacles to the advancement of the technology. Vitrification, which is a newer flash-freezing technique, allows eggs to be frozen so quickly that potentially damaging ice crystals cannot form.
Previously, the potential for viral contamination of the liquid nitrogen tanks used in the vitrification procedure, plus a lack of a comprehensive study of the technique had slowed acceptance of vitrification in the United States. However, with Dr. Jain’s clinical trial, a new vitrification method is employed using closed containers, approved by the FDA for investigation, which protects the eggs from viral contamination.
“Our success in egg freezing has yielded one of the highest published pregnancy rates in the country, with the birth of more than twenty babies,” explains Dr. Jain. “We are optimistic that following this trial, we will be able to expand our abilities, simplify the reproductive process and increase the rates we are currently seeing.”
“We hope to dramatically alter the fertility preservation options for women—particularly for cancer patients,” added Dr. Jain. “And because we have seen no increase in the overall rates of miscarriage, birth defects and chromosomal defects for babies born from frozen eggs over the rates seen with natural pregnancies, the results of this trial are even more relevant.” more…
