No no testing on this tissue, as I wasn't told prior (despite three previous MCs) that this was an option for us-pretty annoyed by that tbh, if only we had been told/prepared, maybe we could have kept something for testing. As we have a healthy son I am hopeful it's not something to do with us, but likely as you say the embryo/egg/sperm. But yeah if that is the case what do we do next?!
I haven't done enough research but from the brief stuff I know about karyotyping and if either of the couple has a balanced translocation , it can still result in a healthy pregnancy. It's all about the chance and that particular pregnancy. If you think it's likely the embryo, if your losses are all early losses and unlikely due to your uterine environment, I would say doing IVF with PGT A testing gives you the best outcome to get a healthy chromosomally normal embryo. It's not 100% and there's some limitations but at least it prevents further potential losses due to having implanting a chromosomally abnormal embryo. Example if I had gotten pregnant with either of the 2 of 3 embryos I had that had an issue, it would have resulted In me having another MC. Hope this helps.
Following this. Have you sent your miscarried tissue for testing? I am sorry for your losses. We didn't do genetic testing ourselves but after a few MCs we decided to do IVF with PGT A testing. My MCs were early so I'm quite convinced it's due to chromosome abnormalities. We recently tested 3 of our somewhat good quality embryos and 1 of 3 was genetically normal. However we didn't do genetic testing ourselves because most early losses are due to abnormality with the embryo itself, not either of the parents, although I know the latter can also take place. I think another type of PGT can then be done on the embryos. Hope this helps. x
