From BBC:

Sperm quality significantly deteriorated and testicular cancers increased over recent years, a Finnish study says.

The study in the International Journal of Andrology looked at men born between 1979 and 1987.

The University of Turku research suggests environmental reasons, particularly exposure to industrial chemicals, may be behind both trends.

A UK expert said chemicals may affect the development of male babies.

Finnish men were studied as they have previously been shown to have some of the highest sperm counts in the world.

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

‘Danger chemicals’

The researchers looked at three groups of men who reached the age 19 between 1998 and 2006.

Men who were born in the late 1980s had lower sperm counts than those who were born in the beginning of the decade.

Total sperm counts were 227m for men born in 1979-81, 202m for those born in 1982-83 and 165m for men born in 1987, respectively.

In addition, the researchers observed that there was a higher incidence of testicular cancer in men born around 1980 compared with men born around 1950.
