Hi all. I've about to start my 7th round of ivf, 3rd with donor eggs. Twice I didn't have anything to transfer, 4 failed to implant and 1 natural mc. i have one frozen embryo left. I've had a uterine biopsy and know I have some immune issues, thyroid antibodies and too few NK cells. We've tried IVIG, prednisole, tacrolimus, clexane and aspirin. The clinic now want to try a granocyte protocol. Has anyone got any experience of this or even heard of it. Seems to be some kind of growth protocol but from what I've read the side effects are quite severe. I have a meeting with the clinic in a couple of weeks but just looking for any information I can find. Thanks.
