'MEN are at risk of weaker sperm depending on where they live, a study warns.

The fertility of thousands, potentially millions of men, may be experiencing fertility decline without realising.

Researchers in China discovered that men who live in heavily polluted areas may experience poor sperm motility.

Motility is how well a sperm swims. The stronger it is, the easier the sperm can swim in a forwards direction in search of the egg.

But male fertility relies on a number of sperm parameters - inluding sperm count, which is the concentration of sperm per ejaculation.
