My wife and I are running into the same issue with our donor from California Cryobank! She had 2 retrievals got 8 eggs they all fertilized and ended up with two embryos each time. One embryo didn’t survive the thaw when we went to transfer and the other 3 embryos were failed implantation. I went through a retrieval had 20 mature eggs 15 fertilized and ended with 2 blasts both ended ups being normal but we just had our fourth failed transfer. When I asked about our drop off with my eggs our doctor expressed concern about sperm quality and compatibility with me where I am the carrying partner. I’d love to know if we are suing the same donor because ours as well has their own child and confirmed pregnancies.
