Are you talking about PGD? the genetic diagnostic of the embryos before they are implanted?

PGD (pre-implantantion diagnosis) and PGS (pre-implantation screening) are the same thing.

It is useful if you have a known chromosomal problem or if you have had a lot of miscarriages for presumed genetic causes. It costs about $5000 extra, and it's never covered by insurance. But, it will be able to tell good embryos from bad embryos. You do want to make sure you're getting the full 46 chromosome comparative genomic hybridization PGD (where they look at all the chromosomes), rather than the older FISH PGD, where they only look at about 5 chromosomes.

I did it, because I have a balanced chromosomal translocation (2 broken chromosomes with pieces swapped) which caused me to have 5 m/c. We had to do 3 IVFs in a row before we found a single normal embryo to transfer. It was very hard to continually go through IVFs and be told that we got nothing.

I chose to do it, because my m/c were happening at 10-12 weeks, so it was too hard on me physically and emotionally to keep seeing heartbeats and hoping; also because we knew that about 90% of my eggs would be bad. If my miscarriages were earlier, I might have just kept trying without PGD, knowing that if a good egg popped up, it would probably stick.

Thanks E for the clarification!!!!

Thanks EELC, to be considered for a future, hope not, but thanks again.
