ATLANTA, Ga. (Ivanhoe Newswire) -- More than six million American women
and their partners face some kind of infertility issue. Fertility treatments
like in vitro fertilization have helped millions, but what about women who still
can't conceive?
In 1997, embryologist Michael Tucker became the first United States scientist to
produce a baby from a frozen donor egg. Freezing eggs was groundbreaking
technology then, but…
"The potential was as low as five percent per thawing that you would actually
end up with a baby," says Michael Tucker, Ph.D., an embryologist with Georgia
Reproductive Specialists in Atlanta. "These were not good odds."
Now Dr. Tucker says he's found a new process called that significantly improves
the odds.
"By avoiding ice formation -- especially with the human egg, which is the
largest cell in the human body -- we are able to get much more consistent
survival of the cell," Dr. Tucker says.
Eggs are flash frozen in thin tubes, then thawed later for use. Dr. Tucker says
80 percent of eggs survive this process … compared to about 50-percent with
conventional freezing. And that means better odds overall.
"That's what you want to be able to say to an individual woman, we can offer
consistently a 30 percent chance per attempt of thawing your eggs using this
process of actually having a live born baby," Dr. Tucker says.
After three years of unsuccessful fertility treatments, Kurena and Mark Hill
became Dr. Tucker's first test case for vitrification. Now they have Rylie --
Dr. Tucker's newest success story. The new egg freezing technology is still
experimental, and the idea itself is still controversial. But for the Hills,
having their daughter means everything.
"Oh my God, she means … sorry to cry, but she means so much to me," Kurena says.
"She's such my miracle."
It's too soon to say whether this new egg freezing technique can be an option
for women in their 30's and 40's trying to save their eggs for the future. The
American Society for Reproductive Medicine warns that egg freezing in general
"should not be marketed or used as a means to defer reproductive aging."
