The world's largest sperm bank has started turning down redheaded donors because there is too little demand for their sperm

Ole Schou, Cryos's director, said that there had been a surge in donations in recent years, allowing the facility to become much more picky about its donors. "There are too many redheads in relation to demand," he said. "I do not think you chose a redhead, unless the partner - for example, the sterile male - has red hair, or because the lone woman has a preference for redheads. And that's perhaps not so many, especially in the latter case." Schou said that the only reliable demand for sperm from redheaded donors is from Ireland, where he said it sold like hot cakes. He said that sperm from donors with brown hair and brown eyes was particularly in demand, because of the bank’s large customer base in Spain, Italy and Greece. Indian sperm was also hard to find, he said, because India does not allow sperm or eggs to be exported, causing a problem for childless international Indians. It is interesting to see that people only want sperm from donors who have similar racial and ethnic characteristics to themselves.
