The world’s biggest sperm bank has rejected ginger donors due to lack of demand.

Denmark’s Cryos sperm bank, which provides women in 65 countries with sperm donations has started turning away redhead donors.

The director of Cryos, Ole Schou, said there had been a peak in donations, which has allowed the sperm bank to be more selective.

He said: “There are too many redheads in relation to demand.

“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.”

But demand for ginger babies hasn’t dropped in Ireland, says Schou, where sperm from redheads sells “like hot cakes”.

The most coveted sperm is from men with brown hair and brown eyes, largely because most of the company’s customers come from Spain, Italy and Greece.

Cyros sperm bank helps to impregnate around 2,000 women every year.

IVF Australia medical director, Associate Professor Illingworth, said the same thing would never happen there, because there aren’t enough donors in the country.

He said: “The problem we have is a shortage of donors. We’ll happily take all the readheads we can get.”
