Check out this article I thought it was really interesting:
huffingtonpost.com tv-sperm-count-harvard-study infertility
Basically, researches have made a connection to men who watch more then 20 hours of TV have a lower sperm count, as opposed to those who do not.
What I actually found even more interesting is in the slideshow at the end of the article, lists other sperm zappers such as BPA. BPA is commonly found in register receipts - YUCK. Make sure to wash your hand after a purchase. I think I will try to not hang on to these very long either.
FYI- BPA is bad news, for those unaware:
A report from the United States Food and Drug Administration (FDA) in 2010 warned of possible hazards to fetuses, infants, and young children. Canada was the first country to declare BPA a toxic substance!
