What is the effectiveness and safety of egg freezing technology (II)

The unresolted data from Tucker, who needs more data to support the success rate, is similar to Noyes's: 36 of the 98 cases of trying to get pregnant with their frozen eggs at Sheedy Grove Reproductive Medicine Center were already in or out of pregnancy.
means that women have a 36.7 percent chance of being or having children through frozen in-body fertilization, a probability and success rate that varies with age, similar to Noyes's results.
Sarah Elizabeth Richards cites these positive results in her article for the Wall Street Journal, "Why I Choose to Freeze Eggs (And You Should Do The Same).
between the ages of 36 and 38, she froze 70 eggs for nearly $50,000.
, however, larger data from more clinics show that the high success rates at New York University's Center for Reproductive Medicine and Sheedy Grove's Center for Reproductive Medicine are just one example.
a meta-analysis in 2013 showed that 2,265 egg thaws and embryo transfers in 1,805 patients had a success rate of only half what Noyes described.
for patients who transplanted three embryos at a time, the probability of a successful pregnancy at age 35 was 19.3 per cent, 16.5 per cent at age 38 and 14.8 per cent at age 40.
of frozen eggs use this set of data to claim that the failure rate of frozen eggs is too high.
to draw clearer conclusions from these opposite data, I consulted Kukluk Oktay.
is a reproductive endocrinologist at New York Medical College and is known for his revolutionary research into ovarian tissue freezing, a technology that provides reproductive protection for cancer patients.
was surprised that a 2013 meta-analysis was used against autonomous frozen eggs.
he believes is a more conservative assessment because the data come from infertile patients who are themselves less likely to conceive than healthy women.
, he believes the results are the most valuable data available to patients.
, he also believes that, like Noyes, it is not desirable to conclude the success rate of pregnancy for egg providers of different ages in only a few cases.
"there is no real study of whether autonomous frozen eggs can help women maintain fertility."
," Oktay said.
like Patrizio, he told me it's because women rarely actually come back to thaw their eggs after freezing them, healthy or not.
so doctors can't give any assurance that the data available looks good.
because there are no criteria for comparing the statistical programs of different clinics, these figures become even more difficult to understand.
the Centers for Disease Control and Prevention (CDC) and ASRM were not traced back to egg freezing.
they warn patients not to use their data to compare and select clinics, as some clinics turn away elderly, infertile patients or end treatment early when treatment is ineffective.
in the choice of clinic, patients often rely on uncertain reviews.
"You need to look at third-party data.
," says Gina Bartasi.
founder and chief executive of Fertility Authority, the parent company of Egg Bank, compared the choice of frozen egg clinics to the choice of hotels in interviews.
Egg Bank makes it easy to compare the prices of different clinics for women (new York University's reproductive center charges $2,400 more for a single frozen egg than Cornell Universityville Hospital next door), but it can't compare the success rates of different clinics.
most important, says Patrizio, is to let patients know that frozen eggs are not maternity insurance but just "hope."
Oktay tells patients that "insurance terms guarantee you compensation in the case of a house fire" so "frozen eggs are not an insurance policy, they are a lottery ticket."
told patients not to rely on frozen eggs to delay fertility.
" freeze your eggs and pretend you haven't done so.
staff at the Shedy Grove Reproductive Medicine Center at The New Year's Day, displayed a high-definition image of a sample of mature egg cells.

as long as you work hard enough and spend enough time, money and energy, anyone can become a parent.
Egg Bank sees autonomous frozen eggs as part of a trend that encourages women to take control of their reproductive destiny.
Richards told me that the frozen women she knew spoke of their psychological strengths, in part because frozen eggs reduced the stress of their relationship.
believe that these frozen eggs will eventually take effect, you can live with more confidence, " he says.
" frozen eggs give women the right to decide their own way of life, giving them more choices to free themselves from physiological hits.
, however, behind this empowerment lies a deeper social bias.
Emma Rosenblum found in her 2014 Bloomberg BusinessWeek cover article that, in fact, the main reason women choose frozen eggs is that they haven't found a partner yet: "Having a baby later?" Will frozen eggs really liberate your career? Noyes' team surveyed 183 frozen egg patients about the reasons for delaying childbearing and found that only 24 percent were career-motivated, while 88 percent said they did not have a partner.
whether or not this new choice emerges, women are still expected to become mothers, and if they fail to have children, society and women themselves will think that she will regret it for life.
the opportunity to freeze eggs, but also to deepen the traditional expectations of women.
In the process of understanding frozen eggs, I was hit not only by the unclear technical prospects, but also by my own inability to reach the psychological state required by it: I believed in the technology to freeze my eggs, but I couldn't believe that it really changed my life choices, that it didn't really make me choose to delay having children, that I really chose not to rely on men, that I really wanted to adopt or that I really chose not to have children.
't know what I'm going to do.
What I know for sure is that I don't want to pay for this technology that makes social problems worse: rich women can choose when and how to have children, while poor women can't; women are still expected to have a child of blood; even if a third of infertile couples are because of men's problems, infertability is still a woman's fault and must be addressed by women."
"This feeling has always surrounded me," a friend of mine told me, and for her, frozen eggs made her feel "lonely, ashamed, and hopeless."
What I'm equally sure about is that I don't want to fall into the fate of devoting an ordinary and bright month of my life to the puffiness, pelvic ultrasound, weight gain, and deep worries about the future.
If I choose not to freeze eggs, I will live up to the advice of Noyes, several New York Times authors, and neighbors I meet while walking my dog, and I will live up to the statistics that show that women's fertility declines with age, and the best available technology solutions on the market."
in the future, I might blame myself for not being able to have children.
so it seems to me that frozen eggs are not maternity insurance, they're just a partial way to help you avoid regret.
: In the last few paragraphs, the writer Abby Rabinowitz gives his thoughts and choices.
women around the world, the right to have children on their own is a long struggle from the past to the future.
egg technology, which has not yet been identified for its success rate and long-term risk, clearly does not solve the problem once and for all.
, however, it cannot be denied that if the technique of freezing eggs is technically improved, it will also provide more possibilities for women's emancipation, as will the development of contraception and abortion.
