2010/2011 Egg Donation Success Rates & 2013 Egg Freezing Info

Unknown-1For egg freezing, a new procedure, there’s limited success rate data available because few of those who’ve frozen their eggs have come back to have them fertilized and implanted, but here’s a link to an info and advocacy website called Eggsurance.

A May 2013 study finds that to date ”Women whose SF [slow frozen] eggs were preserved before age 30 had a greater than 8.9% likelihood of implantation per embryo which declined to 4.3% for embryos from eggs frozen after 40. For vitrification [VF] cycles, implantation success declined from 13.2% for embryos from eggs frozen at 30 to 8.6% for embryos from eggs frozen at 40.”  Success rates may change as procedures evolve.  This is only the first layer of data, assuming these eggs have formed embryos, so there’s lots more to explore in thinking this through for yourself. Cost: in the $10,000 range, plus meds and annual maintenance fees.

CDC ART report, 2010 (latest final data available) & 2011 preliminary data

ART (Assisted Reproductive Technology) currently assists the conception of about 1.55% of US births. In 2011 (preliminary data), that was 61,610 babies born to 47,849 mothers (or maybe a few less mothers, if one woman had two deliveries in one year). 163,038* ART cycles were performed, with a success rate of 29.3% overall, and a failure rate of 70.1%.

Snapshot (detailed chart below): success rates per cycle with woman’s own eggs within the population of people trying (who generally have not succeeded on their own without IVF for some amount of trying, so it’s not representative of success rates at getting pregnant on your own at those ages): Under 35: 41.5% / 35-37: 31.9% / 38-40: 22.1% / 41-42: 21.4% / 43-44: 5% / over 44: 1%

Success rates per transfer to womb, of embryo made with your own eggs (a smaller set than the cycles): Under 35: 47.6% / 35-37: 38.3% / 38-40: 28.1% / 41-42: 16.7% / 43-44: 7.4% / over 44: 1.8%

Success rates per transfer with donor eggs at any age: Fresh: 55.8% / Frozen: 34.9%

To track annual success rates on IVF attempts by age (with non-donor eggs) and overall (with donor eggs), go to the National Summaries on the CDC ART (Assisted Reproductive Technologies) site.

They give you some helpful info, but it’s broken down by the number of cycles, not by the numbers of people involved (so you can’t tell when a person is attempting several times, or what proportion of the set of people trying end up with a live birth).

Success rates for women working with their own eggs are broken down by age, but not the rates for women working with donor eggs — because “patient age does not materially affect success with donor eggs.”  The drawback there is that you don’t see what numbers of women in each age range are attempting egg donation — but I assume the majority are over 40 (let me know why if you presume otherwise).

ART figure48lgWhile the success rates for these technologies have improved over time overall, especially for younger women, the numbers of attempts and of births declined between 2008 and 2009, along with the total number of US births, but have resumed their rise since then. (Chart data.)

Pools of attempters are limited to people encouraged (or allowed) by their doctors to proceed (so again, it’s people having issues with fertility, but not too many, so it’s not the set of all people), as well as by funds available.

About.com lists the current cost of an egg donation cycle at $25,000-$30,000, not including medications, and the cost for non-donor IVF as $12,000-$15,000 per cycle.
