Caveat emptor, as in all else. Emphasising some characteristics, one could list me as an A-1 possible donor, whose genetics one would love to pass on to future generations. Looked at from another perspective, one could list me as a "Red Flag - Approach With Caution" donor. How my children have turned out would tilt the balance in favor of the former, and yet...
I am not sure why people are going in this direction to begin with. It seems like an inauspicious start for a child, to have a donor father. It would make me feel as if I were a bit of software. Note that I say this as one whose father was out of the picture from age six on.
