I'm 45, just had 1st failed ivf. previously had 2 fld iui's and 2 cxld. will try ivf again in jan. are more iui's a waste? insurance will cover them

Donor egg: Are you using a donor egg? That would be most rei doctors recommendation at this point. At 45 after failed iui's and failed ivf, nearly every rei doctor would likely recommend donor egg. Not to do so would be somewhat insincere, as promising a pregnancy at 45 with your own eggs is highly unlikely. I'm not an rei specialist, though, you might consider asking this question directly to one on ht.
