From the book Everything Conceivable: How Assisted Reproduction Is Changing Men, Women, and the World by Liza Mundy (Alfred A. Knopf, New York, 2007)

At the entrance to the hall, unavoidable to all who entered, was a booth maintained by Scandinavian Cryobank, a subsidiary of Cryos, one of the world's largest sperm banks. As one might expect, Scandinavian Cryobank specializes in Scandinavian sperm donors: specifically, Danish donors enrolled in graduate programs at "major Scandinavian universities," men so mentally and physically superior that they passed "some of the most exacting genetic testing in the industry." Deliberately recalling another era when northern European men inflicted their genes on women of other nations, sales staff were distributing wry little buttons announcing "Congratulations! It's a Viking!" underneath which was a photo of a very blond, very sturdy-looking baby. A banner advertisement noted that the company caters to gay and straight, black and white, male and female. Under the happy, we-are-the-world tableau of patients, it added that it serves patients "as energetically as our ancestors once grabbed countries."
