I’m with an individual consultant for treatment - so I see him for all my scans, he does the protocol, EC and ET himself, working with CRM Care as a satellite clinic. So I see him at his consulting rooms for all my appointments and go to CRM for EC and ET, it’s their facilities and embryology team & lab. Nurse at CRM said 60% of their patients were satellite patients - most of the Harley St private consultant’s who offer IVF treatment seem to work with CRM, as does Zita West’s clinic.
Re: hard shells, that’s for eggs not embryos. A thawed frostie is no different at all to a fresh embryo - makes no difference at all to its ability to hatch, it’s not got a hard shell like an egg has, they’re completely different structures. So no reason your blasts should have needed assisted hatching at all - I think the evidence for it is pretty flimsy at best, so just as well to have saved your cash!
An egg being damaged by ICSI is only likely to be damaged if its a particularly fragile (and prob poorer quality) egg, or in the hands of an inexperienced embryologist - though it is, as you say, a possibility, it is very rare.
As far as I’m aware, all ICSI does is to level the playing field to IVF if there are sperm issues (or hard zona pellucida issues for thawed eggs) that would make standard fertilisation difficult - I don’t think it increases fertilisation otherwise, as that’s mostly down to egg quality.
And similarly, the drop off of embryos to blast is also down mostly to egg quality - so if I have a higher incidence of chromosomally abnormal eggs due to high FSH (as in, higher than would be expected for my age), I’ll get a lower fert rate, and a bigger drop off. I didn’t ever expect to have enough eggs to be able to even consider being allowed to go to blast (Dr says they say 3 good embryos at day 3 for extended culture). I might get loads of eggs but hardly any embryos if I have crappy eggs! I’ve been absolutely nailing all the supplements for egg quality, but who knows…
My egg reserves were spectacular when I was 28 and was diagnosed with PCOS, but then when I came off the pill to start TTC aged 33 and we discovered my AMH had declined 93% in 5 years, ugh. That was absolutely devastating.
We were advised to go pretty much straight to IVF as it looked like I wasn’t far off early menopause. Although Dr says my response isn’t that of someone with borderline POF, so the picture doesn’t seem to be quite as bleak as it was 6 months ago.
Can you believe I’ve never taken a pregnancy test?! Wish I had at least had a practice run, as it’s gonna be gutting when I do take my first ever HPT and see a BFN, when there’s £16,000 of treatment riding on it! :(
