late fertilisation of mature egg

I was told by our embryologist that only 3 of the 6 mature eggs collected were fertilised by ICSI on Sunday however today they’ve advised there are currently 4 embryos as one fertilised later? How can this happen if ICSI was being used and will that embryo have any chance of making it to day 5 for testing or is it likely to be poor quality because it was a later fertiliser (not sure if that’s even a thing sorry for the crazy terminology) any advise would be much much much appreciated. Thank you xxx

hi, sorry I don’t know the answer but I would want the same question answering too, I could understand if it was standard IVF but with it being ICSI how do they fertilise later. Unless they did inject the sperm and it was just a slow fertilisation and they didn’t notice. I would definitely ask them how that worked just out of curiosity. As for the embryo, I have seen and read so many stories where the ‘weak’ or ‘weird’ embryo made it to blast and even live births.

I had a slow embryo which developed but a day behind and that made it to blast and they transferred it, unfortunately it didn’t result in pregnancy as it didn’t implant but it made it to transfer!

Also someone I know their embryo that made it to live birth. They said that they were watching the embryo on one of the maps you can pay extra for and while they were watching one of the embryos like shot something out of it. But it made it to blast and live birth. So the weird and wonderful little embryos can be the best ones too

Good luck ❤️

Thank you so much for your response. I feel like I’ve just about exhausted every single question and then something else happens. My clinic must hate me and with our low numbers going to need a bid antihero cycle next month so feeling awkward. It’s so tiring isn’t it. All my friends and family think because we are doing IVF we are gauranteed a pregnancy and it’s just not the case. I get to the point I’m done then a few days pass and talk myself into going again. Hopefully this might be the kink in the norm we need and be our miracle xxxx

Ask them as many questions as you want to, that’s what they are there for and never feel like you are annoying them, they will get it all the time and will know how stressful it is for everyone. I know I get it we did our first round of IVF which was NHS funded and we only had that one embryo that made it, so when it didn’t work we had to then make the decision to pay for our next cycle, but then all the family and friends were like well now you are paying it’s definitely going to work! I was like erm no you still have the same kind of treatment etc. just this time they can make tweaks to suit you better or try a different protocol as they have seen from the first round what needs to be changed. But you’re right a lot of people just see positives and births from IVF and not the true side of it. It’s so stressful but I really do hope everything goes well for you xxxx

I don’t think anybody understands fully unless they go through it themselves. Much love to you ♥️

Same has happened to me - I had egg collection Monday 11 have fertilised + 2 they’re continuing to monitoring. 5 day report Saturday 🤞🏻

I actually had this happen on my first round but a + 1 and that one actually ended up being my euploid after PGTa!

Wow congratulations those are great numbers! Keeping everything crossed for you Sunday!

The +1 that ended up being your euploid did you transfer? I had a euploid after PGTa testing last cycle which we transferred in January but unfortunately didn’t stick xxx

Yes we transferred but sadly miscarried at 8 weeks.

It is great numbers and I know I should be grateful for them; but at 40 I’m ready to see a steep decline. Our first round I had 30 mature eggs- 16 fertilised- 4 and my +1 sent for PGTa - one euploid. I followed different meds this time and had more follicles but less eggs - 19 eggs- 15 mature - 11 fertilised + 2 hopefully. I seem to respond well to the stims as my reserve is still good for my age but it’s the quality that’s the important part. I’m feeling quite impatient for Saturday - just keeping fingers and toes crossed. 🤞🏻 I’d be delighted with one more euploid and another shot 🤞🏻🤞🏻🍀

I’m so sorry to hear you miscarried 💔

You’re doing amazing! My numbers have already fallen off a cliff and I’m 36. Our first IVF round was when I was 32 and we collected 18 eggs ended with 9 embryos and 1 live birth. Last round 18 months ago we collected 18 eggs, 6 embryos (PGTa tested and down to 4) but 0 births 😢 and this round collected 9 eggs, 6 mature, 3 fertilised + 1 so waiting to hear if any made it to 5 day to test Friday. Fingers crossed this is a lucky month for us both xxxx

Oh I hope so ❤️ it is tough holding on to hope for sure - but thats just what improves our strength and resilience. We’ve got this 💪🏻

I had a natural birth (unassisted) - my 12 yr old son. I didn’t even think secondary infertility would hit. We had treatment on the NHS years ago which was shocking and left us with no faith in the consultants and lead us to just give up and come to terms our family as a 3 - he’s flipping amazing and a true blessing - although the teenage attitude is showing its head 😂!

But we had a change of heart and Headed last year for a fertility MOT which showed promise and strictly said we would try ONE round and one round only 😂 but with the miscarriage and the what ifs - here we are. I’ll have one more retrieval on our package if we’re unsuccessful this time- sincerely hoping it’s not needed. Wishing you the BEST ❤️

This is unexplained secondary fertility for us also. I was blessed with the most amazing beautiful daughter when I was 18 and she’s 18 herself now. It doesn’t make it any easier though does it. I really hope you don’t need your final round. We’ve said we will do one more round after this one and then we’re done but you know what it’s like 🤣 wishing you lots of luck, hope and everything else positive ♥️♥️♥️♥️
