The average sperm cell swims at 8 inches per hour.

In 2005, German TV channel RTL aired a show called 'Sperm Race' where male contestants donated sperm samples that were then raced toward an egg under a microscope. The man whose sperm reached the egg first won a red Porsche Boxster.

There's a children's book titled "Where Willy Went" detailing the adventures of a sperm.
