Scientists are now advising professional male cyclists to freeze their sperm before they begin their careers. It seems that the rigorous training causes a dramatic drop in sperm quality. Factors like heat from the tight clothing, friction of the testes against the saddle, and stresses on the body from the physical demands of the sport could all be responsible for the increased risk of infertility.
Over the years I've heard a lot of reasons for male infertility. I decided to do a little research and I've rounded up some lifestyle practices that can lead to it. (I've added a few fake examples, too!) Find out if you can spot the real from the fake and be sure to tell all your guy friends how to spare their sperm!

6/6
i don't like that i know so much about sperm counts 
1that last one made me giggle with the possibility that if it were true- if a woman didn't want a child she could just bulk buy mountain dew!!
6/6...
26/6 - I'm actually glad I aced that quiz.. since I have them lol
36/6, yay! A great resource for any guy or girl interested in this stuff is Harry Fisch's "Size Matters." (Hint: The "size" is actually more in reference to a guy's gut! Fat guys just aren't as fertile. Even if he's rail thin, but has a basketball gut--ew!--it's still a sign of poor fertility.) Okay, I'll stop playing little miss know it all now.
Great quiz, Tres!
45/6 and I don't even have a penis.
56/6 pretty easy! Just guessed and its really obvious. I heard about the whole mountain dew shrinks your penis, but never believed it because there are so many rumors going around. Fun!
66/6 - I'd sure hope so after 10+ years of fertility treatments!
74/6. not bad for someone w/o a penis.
