Embryo cell division... too fast?

Wife is going through IVF. She transfered 2 embryos on day 3. The embryos were both grade 2. One was a 12 cell and the other 11 cell.  My question is this. At day 3, I have read that an embryo should only have 6 - 8 cells. Could this be a problem with 12 and 11 cells on day three? Can cell division be too fast or is it a sign of healthy embryos doing what they are supposed to do?

Some facts:

Male Fertility problems to include count, morph and motility.
11 Eggs retreived
8 fertilized
5 made it to transfer day 3
2 ET and of the remianing 3 none were able to be frozen

here's what the latest science seems to says: fast dividing cells on day 3 have a high likelihood of dying because a large proportion (80% I think) are chromosomally abnormal. So fast-dividing embryos are a cause for concern. For this reason, fast-dividing embryos have traditionally been avoided, and deliberately not implanted unless there's no alternative. So that's the bad news. Here's the good news. A recent study in 2008 took a closer look at fast-dividing embryos, to find out more about them. It turns out that although fast-dividing embryos are more likely to not survive beyond day 3, those that DO survive to day 5 end up being the very best embryos overall - even better than the normally dividing ones. In other words,  they're the best so long as they can get thru the 'likely-to-die-early' stage. So if your IVF clinic is automatically excluding fast-dividing embryos, they should read this recent research, by Luna and colleagues (2008). hope that helps.

My DH and I had our transfer 4 days ago. The lab tech that came in told us on day 3 they want to see the embyros between 6 and 9 cells. We had two transferred, one was 8 cell and the other was a 9 cell. But really who knows, as far as the reading I have done appears each lab grades the embryos differently too.

I read that 6-10  cells is good for day 3.  I am not sure what it means if there are more - maybe nothing  - it's just dividing slightly higher than average??

Don't want to impose, but did you ever discover why you miscarried? Good luck this time around.
