Actually, thanks to quality time spent reading the "People's Book of Lists" in 8th grade, I knew that off the top of my head (should I admit that?). I did just do an internet search to make sure I was remembering correctly though.
Incidentally, extreme low sperm count is considered around 20 million (some of our friends who live on the anabolic board probably fall into that category. LOL). And according to one study, sperm count actually doubled in males when they spent extended periods of time away from their mates. Some counts measured as high as 712 million....no wonder my balls felt like they were going to explode when my arm was in a cast.
