A new study has blamed falling sperm quality and rise in testicular cancer cases over the recent years on environmental reasons, particularlychemical exposure. 

Researchers from the University of Turku examined three groups of men born between 1979 and 1987, and found that those who were born in the late 1980s had a lower sperm count than those born at the beginning of the decade, reports the BBC. 

The study subjects were Finnish men because they have previously been shown to have some of the highest sperm counts in the world. 

But the scientists were never sure if this was because of their genetics or because they were exposed to fewer harmful chemicals.
