I am a recipient of donated embryos and have tremendous respect for couples that have chosen to donate their embryos. While I recognize the magnitude of this gift, I have never been there and cannot fully understand what a couple goes through when donating their embryos. Below are links to sites that are for donors and hosted by other donors. If you know of a site that would be beneficial to some that has donated their embryos or are considering donating them, please let me know so that I can add it to the list.
Embryo Donation (Babycenter.com group)
Embryo Donation & Adoption forum (both recipients and donors represented here)
