Next we talked about Balanced Translocation. I've included an article that explains this below, which will help you. I struggled to understand today! They can give us a blood test to check for this to see if one of us is a carrier.
Bascially I learned that of couples trying to conceive a mere 1% will have recurrent miscarriages. Look at us in that 1%! If you told me there was a 1% chance of my sandwich having glass in it, I would eat the sandwich. I 1% risk is pretty small. I can't believe we're in such a minority! Someone my age, with recurrent miscarriage has about a 2% chance of having a pregnancy with chromosomal abnormalities. That means we have a 98% of a pregnancy being healthy. I guess.
We can have the blood test to see if we have balanced translocation, but that doesn't mean they can do anything to fix it. They can't go in and rearrange my chromosomes! It is what it is, but at least then we'd know what's really causing things. If we have balanced translocation, we can have PGD testing done on our embryos to try to see if any of our embryos are healthy before we transfer them. But, PGD testing is an additional, EXPENSIVE cost. The blood tests we're talking about to test for the balanced translocation aren't cheap either. They run about $900 for Rob, and $900 for me, and there's a good chance insurance won't cover it.
We also went over all the family history we had to provide them, which didn't really show anything conclusive. It wll be nice to get a copy of the counselor's report to see how she summarizes our situation.
This blog is a very SHORT version of the 1.5 hour meeting I had this morning. If we have any more miscarriages, we need to have them tested to see what caused them. They can't guarantee that our first 2 miscarriages were caused by chomosomal problems, but I tested negative for all the other issues that can cause miscarriages, so I think that is what happened with them. If we have the testing and find we have balanced translocation, we could consider the option of donor egg or donor sperm. That might help.
So, now I wait for the counselor to send her report to Dr. Stassart. Rob and I think Dr. Stassart will recommend the testing. Then we will see where we go from there.

Balanced Translocation and Recurrent Miscarriages
A chromosomal translocation is a condition in which part of a chromosome has broken off and reattached in another location. Translocations can be completely harmless or they can cause serious health problems, depending on the circumstances. In the case of the former, many people can have translocations without being aware of the condition. This is usually the case for reciprocal (or balanced) translocation, a type of chromosomal translocation that increases the risk of recurrent miscarriages.
What Balanced Translocation Means:
In a balanced translocation, a person usually has all the genetic material necessary for normal growth -- a piece of a chromosome is merely broken off and attached to another one. However, when that person's cells divide to create egg or sperm cells for reproduction, the egg or sperm cells can end up with extra genetic material or missing genetic material, which could lead to miscarriage depending on which chromosome and genes are affected.
Incidence in Recurrent Miscarriages:
In about 4.5% of all couples with recurrent miscarriages, one or both parents has a balanced translocation. Research has shown that couples with balanced translocations are more likely to have miscarriages than couples without balanced translocations. There's some evidence that balanced translocations involving specific chromosomes are more likely to cause miscarriages than others.
Testing for Balanced Translocation:
Balanced translocation is diagnosed through a test called a karyotype in which blood samples from both parents are analyzed looking for the translocation. Some research suggests balanced translocation in the mother is most likely to be associated with recurrent miscarriages, but fathers can be carriers as well.
Treatment for Balanced Translocation:
There is no cure for balanced translocation, and in most cases, the only adverse effect on health is recurrent miscarriages. For couples affected by balanced translocation, odds are in favor of a successful pregnancy at some point, but repeated miscarriages can obviously be difficult to cope with emotionally.In some cases, couples with balanced translocation can opt for a treatment called preimplantation genetic diagnosis (PGD). In PGD, the couple conceives via in-vitro fertilization along with gene testing of the embryos to be sure that they do not have an unbalanced translocation. PGD is very expensive, however, and not covered by insurance much of the time, which is another reason why many couples are forced to keep trying without intervention.
