I had the same situation at my first cycle, 6 eggs retrieved, 5 mature but none fertilized, they didnt use ICSI though. At my second cycle 9 retrieved 7 mature 3 fertilized with ICSI. We clearly have some fertilization issues, but the doctors dont know is it due to poor egg quality or sperm problem.
I hope it works for you next time, I know how devastating "no fertilization" news can be,
