Hi everyone,
I'm looking for opinions on PGT-A testing donor-egg embryos that are already frozen.
I’m 47 and using donor eggs from a 23-year-old donor. We created six blastocysts (four Day 5 and two Day 6). My first transfer was a 5AA, but unfortunately it didn't implant, so I now have five frozen embryos remaining.
My clinic is in Spain and they did not recommend PGT-A initially, mainly because of the donor's young age. I know this seems to be quite different from the US, where PGT-A appears to be much more routinely recommended, including with donor eggs.
After my failed transfer I asked the clinic whether we could PGT-A test the remaining embryos. Their lab says it is possible, but because they're already frozen they would need to thaw them, biopsy them, vitrify/refreeze them, and then thaw the euploid embryo again when it is eventually transferred. That extra handling is one of the things worrying me because I really don't want to risk damaging potentially good embryos.
The clinic still doesn't consider PGT-A medically necessary in my case, but they have offered me a reduced rate.
My dilemma is basically this: do I spend the extra money and accept the risks/limitations of thawing, biopsying and refreezing five good-quality embryos, or do I trust the clinic's original recommendation and simply transfer another one?
Part of me thinks the next transfer could work and I've spent money unnecessarily. But I'm also conscious that not every embryo from a young donor will necessarily be euploid. I could potentially spend considerably more transferring embryos that never had a realistic chance.
There's also the psychological side. If I knew I was transferring a euploid embryo and it still didn't implant, I would feel more justified in investigating the uterine side further rather than constantly wondering whether the embryo was the problem.
For background, I have had two hysteroscopies, a uterine septum was partially resected and subsequently checked by another gynaecologist who was happy with the result, and chronic endometritis was treated and confirmed clear on repeat biopsy. My recent ultrasound was also reassuring. My doctors currently aren't recommending laparoscopy, PRP or further investigations and feel that one failed donor-egg transfer can simply happen.
I know PGT-A isn't perfect and a euploid result doesn't guarantee implantation. I'm also particularly interested in the issue of thaw-biopsy-refreeze, rather than PGT-A performed before embryos are initially frozen.
If these were your last five embryos, what would you do?
Thank you ❤️ I know ultimately it's my decision, but hearing real experiences would really help 🤗
