Surprisingly, This Is the All-time Age to Freeze Your Eggs

Egg freezing is slowly becoming mainstream. From a medical standpoint, information technology'sno longer considered experimental. Tech companies are starting to offering information technology as a perk. And cryopreservation banks fifty-fifty throw "egg-freezing parties" to convince women that it's a smart way to extend their childbearing windows.

But whether you piece of work for an Apple or a Facebook, who will cover the $10,000 price, or not, information technology'due south important for women who want to freeze their eggs to remember that the historic period at which you practise "stop fourth dimension" doesn't exist in a vacuum — the age of your eggs will touch your chances of really having a baby. If y'all want to put some follicles on ice, at what point is information technology a waste of coin? It might exist afterwards than yous retrieve.

Some backstory: When the American Social club for Reproductive Medicine (ASRM) gave egg-freezing the thumbs-upward in 2012 , they were talking about it specifically every bit a treatment for infertility. Doctors were seeing solid pregnancy success rates using eggs that were flash-frozen, which was peachy news for, say, a woman who was facing cancer handling that might destroy her eggs.

Only the ASRM was cautious to say that they did non endorse then-called elective egg freezing for people who weren't infertile but just wanted an insurance policy for the futurity. They didn't desire to encourage the freezing of eggs that would never get used, and they worried almostgiving older woman a false (and expensive) sense of security.

That doesn't hateful doctors don't do elective egg-freezing; they simply take long conversations with their patients. "Elective egg freezing is a reasonable thing, simply you have to be careful because some people might jump into doing it who don't really need information technology, and for some people it might be too tardily," says Owen Davis, Medico, electric current ASRM president and associate director of the IVF Program at the Ronald O. Perelman and Claudia Cohen Centre for Reproductive Medicine at Weill Cornell Medical Higher in New York City.

If a unmarried woman freezes her eggs in her early on 30s, she might experience some peace of listen, but information technology's all the same possible that she'll meet a partner and have no trouble getting pregnant the quondam-fashioned way. Just if a woman in her early 40s gets cryopreservation, her chances of having a babe might be much lower than she thinks, thanks to the declining quality of women'southward eggs as they get older.

When reproductive endocrinologist Anne Steiner has this conversation with women at the UNC Fertility Clinic, she has a pretty helpful tool to consult: a study she published last year in the journal Fertility and Sterility on the optimal timing for elective egg freezing.

For the paper, she and a squad used mathematical modeling to clarify hypothetical women ages 25 to forty who either did or didn't freeze their eggs, comparing pregnancy success rates against the likelihood that women would really utilise their eggs.

When they strictly compared women of different ages who had frozen their eggs, women who iced before they turned 34 had the all-time chance of giving birth, says Dr. Steiner, who's as well an assistant professor of obstetrics and gynecology at the UNC School of Medicine . Merely in that location was little benefit to women freezing in their 20s versus doing nothing, because they probably weren't going to use them. So the range that maximizes your baby chances without "wasting" a large sum of money on eggs yous might never use is between 30 and 34. (The study causeless women were trying for 1 babe, so certainly, unused eggs could be thawed in the future for subsequent children.)

Here'due south where it gets even more interesting: When Dr. Steiner's team looked at women who froze their eggs versus women who did nothing, they saw that women who did it at age 37 had the biggest benefit. That's where they saw the greatest divergence in the probability of having a baby, she says. Merely it needs a caveat.

"There is this do good over not freezing even at 37, 38, 39, albeit then your chance of getting a baby out of that are much less than if you had frozen at a younger age," says Dr. Steiner. While information technology'southward non a fail-safe, information technology is at to the lowest degree reassuring that women over 35 who are thinking about egg freezing are not too belatedly.

She says the study serves as an education tool. "Our goal is to aid the woman make the decision past asking herself, 'do I want to spend this coin understanding this is my probability if I practice this or if I don't do this.'"

Dr. Davis thinks information technology'southward helpful equally an answer to the question: since this engineering science exists, should every adult female with the means to exercise and so freeze her eggs? "In terms of the toll-benefit analysis, it probably doesn't make sense for every xx-year-old to freeze their eggs," he says. "Similarly, a person over 40 is going to have a harder time expecting those eggs to work for her."

"And at 37, that'south sort of similar the average age of the IVF patient in my clinic. That's actually an age at which you might get a reasonable number of eggs that are reasonably healthy."

In her experience, Dr. Steiner says younger women aren't making appointments to enquire nigh this. "Almost people aren't coming in at xx and saying 'what age should I practise it?' They're coming in [later on] when they hear about information technology, think about it, or information technology crosses their mind. That's where it's prissy to pull information technology out and say, 'Look, this is what you can anticipate to the best of our noesis,'" she says.

"It's expert, also, because at that place was a lot of contend about [elective egg freezing] for a long fourth dimension because of this concern that women would perceive it as something they could 100 percent rely on in the future. It's not perfect."
