Closephine Your DH sounds like a wonderful man and has been so dedicated and committed to this process, I’m so very sorry for these latest results, can only imagine how gutted he must be. once you’re into the realm of IVF then ICSI and IMSI overcome the male factor - and in fact patients with male factor have excellent prognosis for IVF success, because there’s a mechanical reason why you haven’t got pregnant naturally (same with women with blocked tubes) - so ‘fuck yeah science’ etc. I can’t remember - do Serum do IMSI as well as ICSI? IMSI is particularly helpful if morphology is poor, as the super duper magnification can try and find a swimmer that isn’t just the prettiest, but ones that are likely to be genetically strongest. know Serum are absolutely brilliant for male factor, so between Mr Ramsay and Penny, it sounds like you have and will be in the very best hands
Fuzzy I’m so sorry your news today was disappointing, big hugs to you and DH. I am in violent agreement that biopsying at day 3 is a complete waste of time and money. PGS is just a selection tool - that’s it. As you say, waiting to see what makes it to day 5 is a selection tool in itself - not all embryos that make it to blast will be chromosomally normal, but anything that doesn’t make it to blast was almost certainly abnormal. In our first cycle we had 6 eggs, 4 fertilised, but they all arrested after day 3. However gutting this was, if we had transferred at day 3, it would always have been BFN or mc, so the outcome wouldn’t have been any different whether we had transferred at day 3 or not. And for PGS it would have been bonkers to biopsy at day 3 - when the fact they arrested told us they were all abnormal to begin with. Day 5/6 biopsy also enables them to test several cells, vs one cell from a day 3-er
Although the quantities were very different, our May cycle shows why day 5 biopsy made more sense. At day 3 we had 19 good quality embryos - the cost of testing all of these would have been ridiculous. By day 5/6, 19 had reduced to 9 embryos - so testing at day 3 would have been madness, as leaving them in the dish was a very valuable selection tool in and of itself.
If you got a single blast, would you still do PGS? Or would you hold back the biopsy and do another banking round, in order to get more embryos for testing (and batch together biopsies from both cycles for PGS testing in one go)?
Keeping everything crossed for the day 2 update and hope you’re not feeling too uncomfortable
