My RE didn't do B2B, but I know some do. Should be okay as long as you aren't dealing with MFI. Good Luck!
Ugh.....we are dealing exclusively with MFI. DH has a high count but low motility and morphology (although motility has gone up from 28% to 43% - morphology went from 2%-3%).
First RE recommended going right to IVF. This RE said three rounds of IUI first. We are going for the IUI since it's covered by our insurance (IVF is not).
Thanks for the well wishes :)
