Arnt has straight blond hair and blue eyes. He swims, runs, skis on water and snow, and works out. He's not advertising for a girlfriend. His sperm is for sale. Arnt is one of 50 men from Denmark whose sperm sits in one of three metal vats in Manhattan - waiting for a couple or a single mother desperate for a baby. In this case, a Viking baby. The company Scandinavian Cryobank takes credit for 10,000 babies worldwide. Two years ago, the company opened a New York office and began marketing Scandinavian sperm to infertility doctors and their patients with a sleek albeit controversial slogan: "Congratulations, it's a Viking!" Another advertisement shows a blond, blue-eyed baby and talks about his ancestors who beat Columbus to North America. "You'd better build a strong crib," the ad boasts. While some think pursuing the fantasy of a near-perfect child smacks of eugenics, Americans are finding ways to attempt to give birth to designer babies. The freedom to choose the kind of child one wants could create "consumer eugenics," said Jonathan Moreno. "We have cultural stereotypes. Blue eyes, light skin and height are valued. It would be a historic irony if we all ended up looking like that."
