Funny story: My wife works in a fertility center and was looking under a microscope at some sperm in a petri dish. She observered some of them busily trying to penetrate a round object, which the embryologist she was working with confirmed was an air bubble.
The embryologist said to her: "Just like a guy - they'll hump anything!" I guess it's no surprise that is takes billions of the little fellas to have a chance for a few to make it to the egg. -Bryon Deborah Harrell wrote: >http://my.webmd.com/content/Article/60/66971.htm?printing=true > >"A sperm's mysterious journey through a woman's body >in search of an egg to fertilize may be a lot like a >heat-seeking missile locked onto a target.
