Egg fertilization rate

Hey guys what is a common rate of eggs fertilizing? Our first 2 ivfs with DH sperm we had 4 out of 7 fertilize. On this round we did 2 DH (one fertilized) and 5 with donor sperm (3 fertilized) Once again we got 4 out of 7. Guess maybe I expected more using donor sperm.

its just a terrible feeling to feel like you're in the exact same spot that didnt work before. Our last two attempts embryos stopped growing around 8 cells. We've yet to have anything to transfer. Not giving up yet but it just feels eerily similar.

    I was told 66% is textbook and you're close. We also experienced embryo arrest after day 3, which is when the sperm is activated. Hang in there. GL

    If the eggs are not fertilizing normally that means there's something abnormal about them or the sperm, so they wouldn't make good embryos - maybe that helps you feel better. You're not "wasting" eggs, if that makes sense.

    I think your fert rate for both cycles looks pretty good. You're not doing ICSI are you? Even so, that's a good rate.
