Hi Loula,
I just wanted to say that the same thing happened to me with my last cycle, 17 eggs, none fertilised. We're down for ICSI next, but the further SA test for my husband didn't reveal any problems - they tested for something called DZPIAR (which is something to do with penetrating the egg shell) but it was negative. I noticed that the info sheet was dated 1999. Really up to date technology down in Melbourne!
Hey, what happened with your friend?
What made her think it was her egg shells?
Best of luck to her,
WW
