The world's biggest sperm bank is struggling to meet demand despite an all-time high of willing donors and global expansion of its offices in New York and Bombay. Donors are said to be paid US$110 for "very good quality sperm." The sperm bank is Cryos, located in Arrhus, Denmark. Chief executive Ole Schou says they are having trouble meeting the sudden "avalanche of demand from the Western World, mostly from the United States." He says, "We help a tsunami of highly-educated single women who are more demanding and who prioritised their careers and who want to have a child before it is too late.""Cryos plans to expand further in Europe, Asia, Africa and Australia to give it a broad ethnical donor base to meet the demands of people all around the world," says the AFP report on Yahoo News UK.
