There is a group out there called Snowflakes.org that does embryo adoption. I contacted them about adopting embryos, but you cannot gender select. They told me even if I were to do PGD on them, I would have to implant everything that we thawed out. I think the only way to adopt a girl would be if someone in that organziation was adopting already PGD'd embies, and I don't know that there are any families like that involved in Snowflakes. I also contacted HRC when I was told I would not qualify for Microsort, and asked about their families donating their embies. I was told it rarely happens, and when it does, they usually go to a family already using HRC services.
I really only know of that one organization doing embryo adoption, all the other agencies are working through them, so I don't know of a better option if that is who she is already waiting with. We have been pursuing an international adoption for the last year, and the outlook isn't good, I know why she would be reluctant to start that process.
