Hello...DH and I seem to be quickly heading in the direction of IVF w/ ICSI, as well, due to low count, low motility and 0% normal morph. We just met with the RE on Monday. There's no guarantee with IVF, of course. But, IVF, and especially with ICSI, gives you great odds in comparison to even a fertile couple's normal cycle...the odds go from 25% to 50-60% for a fertile couple. And, with our MFI we'll go from 1% or below up to that same 50-60% range.
I don't really buy into the "it only takes one" theory since our morphology is so low...but, ICSI is the only time "it only takes one" is literal. Even if DH only had one good sperm, that would be enough to fertilize the good egg with the ICSI needle (for lack of proper scientific terms)!
It is very scary to think about that kind of cost for only the chance, though...no matter how great the percentage. So sorry that you're both having to go through that!
