We've got the results of a massive new study by the University of California, San Francisco . . . on the different ways we Americans INJURE OUR GENITALIA. 

--From 2002 to 2010, they found that about 16,000 Americans went to the emergency room for genitalia injuries.  69% were male.  And the top seven most common things that caused those injuries were . . .

#1.)  Bicycles. 

#2.)  Razors, scissors, and clippers. 

#3.)  Zipper injuries.

 #4.)  Falling in the bathroom. 

#5.)  Playing basketball. 

#6.)  Playing baseball or softball. 

#7.)  Skiing and snowboarding.
