Well, blow me down with a feather - it survived!
After a ridiculous wait at the hospital on Monday we met with the embryologist [Felix - definitely a name for the list] who told us that our one embryo was at 6 cells - 'progressing at an acceptable rate'. When we went into theatre for the transfer he announced that the embie had grown and was now an 8 cell. Loving that number 8!
We asked a heap of questions about the 'sperm binding' thing. We got a few answers on the 'what' side - it is the stuff that binds the egg and sperm together to allow fertilisation to take place; it was missing from most of the eggs; and ICSI may have overcome it. But they couldn't really give us much on the 'why' except that it was more likely to have been an egg problem rather than a sperm problem. 2 of the eggs were immature, 5 looked ok, and one was good - yea that was the one that fertilised.
So now on with the 2 week wait. This ride sure is a roller- coaster. Preg test September 3rd.
