This is a very generous gesture. I am sure someone will feel blessed to receive your donation.
Just as an aside about the term "adopt". I am not sure if you know, but by using that term you are inferring that these embryos are actually children, and that could have far reaching consequences. For example, it could potentially mean the people you donate to would be subject to the same screening criteria that those parents that actually do adopt born children. It also could mean added scrutiny for everyone who does ivf, and for the doctors who perform ivf. It sounds crazy but there are personhood amendments under discussion in many states. Also, when you look at these embryo donation/adoption websites, you can tell the "philosophical" orientation of the organization by which term they use.
(Perhaps you know this already, in which case, just tell me to mind my own business!)
