When Should I Freeze My Eggs?

Every woman is born with a limited supply of eggs.  As this supply ages, the likelihood of each remaining egg to have the capability to become a baby diminishes.  However, this loss of potential is not spread evenly over the years, rather it is a shallow decline that usually continues into the mid-30’s, followed by a steeper loss that typically happens from the late 30’s into the early 40’s.  Over a matter of 5 years, the odds of one egg having the potential to make a baby decreases by about 80%.  Of course, not every woman is typical and the age at which this transition starts can vary quite a bit.

 

The only way to effectively protect the potential of eggs over time is cryopreservation, also known as egg freezing.  Once frozen, the capacity of the eggs to create a successful pregnancy is maintained through the years.

 

Gynecologists often ask me at which age to refer their single patients to me to discuss egg freezing.  The answer is not simple.  Certainly we do not want to put a patient through this process if it is likely that she will meet the right partner and form a family without ever using those eggs.  It would have been an unnecessary medical procedure with associated expense and lost time and effort.

 

On the other hand, we have to weigh the risk that the steeper decline in the eggs’ potential will happen before the woman has met her future partner and completed her family.  If we could predict when that decline will happen in each woman then this question would be much easier.  Unfortunately, our testing is only accurate in identifying this steeper decline when it is already occurring, at which point we have already missed the opportunity to freeze high-potential eggs.

 

Most of my egg-freeze patients are in their mid-30’s.  On average, at this point, only subtle changes in the potential of eggs have occurred, whereas within a few years, more drastic changes usually start.   Therefore, this timing does make sense for most women, but not everyone.

 

A concern about waiting until the mid 30’s is the possibility of an earlier decrease in egg potential.  While that is unusual, it tends to also be unpredictable.  Factors that contribute may include a history of smoking, a history of ovarian surgery or conditions that may lead to such surgery (e.g. endometriosis), or having a mother or older sister that experienced either an earlier menopause or infertility due to loss in egg potential.  Women with these factors should consider freezing eggs in their early 30’s or even late 20’s.    But, most often, if an early decrease occurs, it is without any predisposing factors and with no known cause.  Therefore, even without predisposing factors, cautious women, who want to minimize the risk of missing the opportunity, should also consider freezing their eggs in their early 30’s.

 

Of course, just as some women unpredictably have an earlier loss, some also have good potential that persists even past 40.  This can be determined at an initial visit with a fertility specialist through sonogram and blood tests.  So, for women who have not yet frozen eggs, even at 41 or 42 it makes sense to come in for evaluation and determine if this could still be worthwhile.

Infertility Podcast Series: Journey to the Crib: Chapter 32: Octomom

By David Kreiner MD

December 1st, 2013 at 8:26 am

 

Welcome to the Journey to the Crib Podcast.  We will have a blog discussion each week with each chapter.  This podcast covers Chapter Thirty-Two: Octomom. You, the listener, are invited to ask questions and make comments.  You can access the podcast here: http://podcast.longislandivf.com/?p=146


A year ago, the Medical Board of California revoked the license of Dr. Michael Kamrava, finding he “did not exercise sound judgment” in transferring 12 embryos to Nadya Suleman, who already had six children at home. The ruling, while not surprising, was illuminating, and it’s worth reflecting on the five things we learned from Octomom:

 

1.      Know How to Say “No”: There is a point where physicians have to make a judgment call. Pregnancies with triplets – let alone eight infants – put the mother at high risk of serious medical complications and put unborn children at risk for developmental disabilities. Physicians need to rely on their professional expertise and experience to know when to turn down a patient request no matter how vehemently it is made.

 

2.      Beware the Patient with Tunnel Vision: Often when a patient comes to a fertility doctor, unsuccessful pregnancy attempts have made her anxious and determined. She might want to get pregnant regardless of the risks that pregnancy may present.

3.      Less is More: In 1999, 35 percent of all transfers involved four or more embryos. In 2009, only 10 percent had four or more. And those high-number transfers are generally reserved for patients with significant fertility challenges. In contrast, Octomom already underwent multiple successful IVF (in vitro fertilization) procedures and had given birth to six children when she had her 12-embryo transfer.

 

4.      Know When to Deviate: While Dr. Kamrava’s deviation from guidelines was an extreme departure, deviations do occur for specific reasons, such as repeated IVF failure, age-related infertility and poor egg quality. It is important to know when implanting several embryos is appropriate.

5.      “Reduce” Risk: Dr. Kamrava complained that Octomom refused to undergo “selective reduction,” which would have reduced the number of embryos she carried to term. Here, again, is an argument for fewer transfers. Had he transferred fewer embryos, Octomom would not have had to face such a difficult decision.

Was this helpful in answering your questions about what could have been done differently to prevent the Octomom case? How much weight do you give your doctor’s recommendation on the number of embryos to transfer?

Please share your thoughts about this podcast here. And ask any questions and Dr. Kreiner will answer them.

Octomom
