Hi Loops,

We had success with ICSI and same as your situation there was no fertility issues found on the female side but DH had low sperm motility and morphology. We only had one successful fertilisation so our emby transfer occured with a 2 cell emby - we didn't even wait for blasocyst stage as there was only one to transfer back in any way and we were told that my uterus was the best place for our emby anyhoo. But that aside, my understanding is that ICSI would be a better option becase they can 'choose' the best, healthiest sperm to fertilise the eggs with in contrast to 'regular' IVF

Has your FS given any indication of why they think blasyocyst stage didn't occur - I guess it could be a range of reasons - even egg quality too, have they any ideas, or suggested an alternate plan for the next cycle?

Hope they can give you some answers - GL for the next round if you choose to try again
