This is a repeat of an old story: A study done in Denmark in 1954 showed
that sperm count had dropped by 30% over the previous 15 years.  At that
time it was attributed to agricultural chemicals leaching into the water.  

Both France and the United States decided to replicate the study since other
countries don't know how to do "good science".  Amazingly they came up with
similar results.

If you add these two studies you get a fertility decline of 60% which would
explain the explosion of fertility clinics around the world.  Perhaps this
is a blessing in disguise as far as population control is concerned.

Seems that antibacterial liquid soap is one of the big sperm killers. A test

done on Danish navy cadets (great in cleanliness) showed about 35% 
infertility if I remember well.
