I feel compelled to share my experience with you because I think it has so many ethical and emotional implications. Of course, it is ONLY my experience and it may not extrapolate, but I still think it is very relevant. I had a bunch of blastocysts and did PGS because I wanted to avoid m/c or Down's (over 35). Only a couple returned normal, but the results had a few things that puzzled me, and since the alternative was to discard the embryos, I decided to retest instead, with a different lab (after also reading articles about abnormal embryos being implanted in Europe and developing normally or retested with different results). Guess what?? More returned normal, PLUS the rest of abnormal ones had totally different abnormality profiles.
So I'm sitting here thinking, how many normal embryos are killed each day after PGS results? How many women who can only produce one embryo that turns out abnormal end up unsuccessful just because of throwing away the embryo? This technology is only experimental, the labs either make awful mistakes OR the embryos are mosaic and good cells may exist that can then lead to self-correction in the embryos. Playing God is awful and heartbreaking. I still don't know what to do with my "abnormal" embryos in this case because I definitely don't trust the results anymore..
