“According to the data, average human male sperm count have dropped by almost fifty percent between 1938 and 1990. At the same time, the incidence of testicular cancer had jumped sharply, not just in Denmark but in other countries as well. The medical data also suggested that genital abnormalities such as undescended testicles and shortened urinary tracts were on the rise among young boys.
“Because the changes in sperm counts and quality of the increase of genital abnormalities had occurred over such a short period of time, the researchers ruled out genetic factors. Instead, the changes appeared due to some sort of environmental factor.”

“From  until 1990, average human male sperm counts will drop by almost 50 percent; during the same period the incidence of testicular cancer will triple.”
