There is an embryo bank in (maybe?) Texas that deals with this very issue. You might google it and locate them.
It's in Tennessee.
There is a website miracles waiting, that people with extra embryos donate to other people. You might want to check it out. I know people searching for them must pay a fee to join, but it could be worth your time
And donor donation is much cheaper then adoption. If you have any questions, please feel free to ask. My twins are a result of donation
i saw a tv special about "snowflake babies". I'm sure if you Google that you will find some info.
