Our first IVF we got 17 eggs 2 put back and 5 frozen. I got BFP but m/c @ 5 weeks. We did a FET only one made it to transfer. Again BFP m/c again.
This fresh one they got 15. 13 out of the 15 fertilized, but then at transfer time we had 2 really strong blasts put back, but none of the others made it to freeze. Is this a sign that something could be wrong with egg quality?
Both DH and I had chromosone testing on ourselves done, those tests came back fine. My Dr does PGD but says it can cause a lot of stress on the embryo. We are currently in our 2ww. Only 6 more days til test time. I was just wondering what your thoughts would be on this.
Any help is appreciated!
Thanks!!!

Some clinics have used PGD to try to improve IVF outcomes. This has been shown to not work in the general population. If anything, it caused more harm than benefit, reducing implantation rates through the slight damage to the embryos. This explains the recent push for non-invasive techniques to try to determine embryo viability.
However, there might be a sub-population in which PGD is beneficial for improving success rates. These would generally be those rare, few women who produce large cohorts of embryos, many of which make it to the blastocyst stage and appear normal, but are mostly abnormal. PGD can work to cull through the many to find the few good ones to transfer.
Again, that kind of patient is the rare exception.
However, women who produce only the number appropriate to transfer (like 1 or 2 blastocysts) would see no benefit. If there are so few, there is no mystery to solve regarding in which embryos to transfer.
Did you test the products of conception? An SAB does not automatically indicate a genetic defect. Embryos that pass complete chromosome analysis can still have an SAB, and sometimes the analysis of the abortus comes back genetically normal.
Did they get to the point of doing an ultrasound? What did they see? Sometimes a genetically good embryo has a lousy ICM, and although the sac (trophectoderm) implants and develops, there is no baby inside. These are called "anembryonic gestations" or sometimes a "blighted ovum".
Of course, PGD is good for screening out genetic disease, like Down syndrome, cystic fibrosis and such. It certainly has an important role.
