mosaic embryos

teamginger13

Has anybody had any experience in transferring a mosaic embryo? I was set for an FET today with our last remaining PGS normal embryo but it did not survive the thaw. The embryologist reminded me that I had one mosaic embryo left from an egg retrieval and couple years ago. I am waiting on a call back from a genetics counselor but am curious if anybody had any experience with this. I read that the success rate is much lower.

I transferred 4 abnormal embryos (2 at a time). We ended up with no mosaics, but apparently the % of rating of what is mosaic is dependent upon the lab that grades them. For my clinic the number was pretty low (meaning it barely had to have any mosaicism before they code it abnormal. I did get pregnant with one of them, but ended up being a chemical. There is certainly a chance of it working though based on the fact that PGS only tests 1 cell from the very outer layer which is NOT where the baby forms. That is what forms the placenta which can certainly still maintain a healthy pregnancy. If the egg is has a good cell mass, likely you could get lucky! Good luck!

Not exactly sure what they are considering mosaic, but we transferred an embryo that was classified as "only 85% confidence on chromosome 22" and am currently 10 weeks pregnant.

@teamginger13 Reading your post- I’m so happy to hear you had a normal healthy baby girls after a number of “abnormally” tested embryos. I just found out that my first 5 embryos may also all be abnormal, 4 are, 1 was inconclusive so will be retested. I am a bit deflated.... But I’m also a few years older. Hoping this last one may be viable. If not, another ER process will start.
