My Preimplantation Genetic Screening (PGS) Results

As a follow-up to my post called “Preimplantation Genetic Screening (PGS): Why You Should Do It,” I decided to publish the results of my two PGS tests. I hope the information is useful to anyone who wishes to compare her results or get a better idea of how maternal age may affect the quality of embryos.

IVF #1: 16 eggs retrieved, 15 successfully fertilized, 10 mature enough for biopsy on day 5/day 6. Results:

My reproductive endocrinologist made three conclusions based on the above results:
  1. With respect to good embryo morphology at day 5, I am among the top 1/3 not only for my age group (39–40) but also for women over 35
  2. With respect to euploid embryos per egg retrieval, I am about average for my age group with 1–2 euploid embryos per cycle
  3. With respect to euploid embryos per biopsied embryo, I am in the bottom 1/3 overall
In other words, though I was able to produce a huge number of okay-looking embryos, I still got only 1 or 2 chromosomally normal ones in each cycle, which is what a woman who is nearly 40 should expect. When you think about, that’s not necessarily bad news. A “normal” woman typically produces only one egg per month, and that egg might not be of good quality. So I am in a somewhat better position (having tested all embryos) and can only hope that the transfer goes well in a few days.

UPDATE:

IVF #3: 26 eggs retrieved, 19 successfully fertilized, 10 mature enough for biopsy on day 5/day 6. Results:

Even though I used a different sperm donor for IVF #3, the PGS results were consistent with those from the previous two tests. For someone my age (nearly 41), these are considered good results.

    A healthy embryo is just the beginning- the above link discusses a study done with rats showing that the mother's age was a big factor in congential heard defects and possibly other birth defects during gestation.
    The study took eggs from a group of young rats and fertilized them and implanted them in older rats while they did the same with the eggs from the older rats.
    About 10% of the rats that were carried by the young rats had a CHD- while 20% of the pups that were carried by the older rats a CHD. Though the following link
    http://circ.ahajournals.org/content/130/Suppl_2/A18016.abstract
    shows that these risks can be mitigated with exercise and a healthy diet both- in short keeping up your current life style.

  2. I found a couple of more links that you might find interesting
    http://www.webmd.com/infertility-and-reproduction/news/20150305/three-parent-ivf-faq
    The first is talking about a new form of IFV where mitochondrial DNA from a donor can be used to correct defects. The second article I have found is about vaccines that a pregnant woman should get - flu and and tetanus, diphtheria, and pertussis
