FG, we're in the same boat basically, sperm (morphology) issues, 1 fresh t/f, 3 frozen t/f and no hint of pregnancy. Our embies have been great with Day 5-6 hatching blasties and 95% cell survival after thaw. DW is apparently normal. Buggered if I know. Our FS says to just keep going for now and see what happens. So it's back to square one, cycle two!
