Hello, I have been through one round of IVF using donor sperm and although 13 eggs were collected, none fertilised. I was devastated. At egg collection I was told that it would be overkill to use ICSI but in hind site it makes sense that it was the wrong advise. Surely frozen sperm would not be as strong as fresh sperm. Do you think that ICSI should be recommended for all frozen sperm? Has anyone had success with conventional IVF and frozen sperm?
