I understand MGC, when I first went through our list I was so upset - not one of them was DH. However we finally agreed of physical characteristics that were plausible, an acceptable medical history and general values/education that matched what we had. Regardless it was a difficult decision. I have re-read the information so many times now that I am pg, just to convince myself that I have made the right choice, though ultimately I think our influence will be much bigger than the genetics.
With this cycle we ended up with an Australian donor, but had used US on previous cycles. No one had mentioned a $2500 fee, so I think it might be just your clinic. I was with QFG in Queensland.
