I have had 5 failed IVFs (I am 40) in the UK (Hammersmith and ARGC) so I decided to go to IVI in Barcelona to undertake a donor cycle. I can highly recommend them. They are extremely professional and take very good care of you. I did have a BFP after my first attempt a few weeks ago but subsequently this led to a BFN. My donor was only 23 and produced 10 mature eggs, 7 of which turned into beautiful embryos so I have another few attempts left. Give them a go and it is not that invasive!
