Do the birth certificates say "donor #15"? What happens if two of his offspring, (from the sound of the article there could be a lot of them), fall in love and don't find out they're half siblings until they go in for their marriage license?
Or worse - what if his female offspring decide they too want fatherless children, and go to the same bank and receive donations from "donor 150"??
Eeeeewwww...
