Common environmental exposures & male infertility

Fertility experts have suggested that worldwide male fertility has decreased over the last 50 years as measured by sperm concentration.

The cause of this infertility is still open to debate, but many researchers believe that environmental exposure to some compounds may play a role. New research out of Glasgow, Edinburgh and Aberdeen Universities seems to support this theory.

Researchers exposed sheep to commonly used chemicals such as cosmetics, detergents and pollutants.  These chemicals are typically encountered by pregnant women and throughout their children’s lives through puberty.

Following exposure, scientists then examined the testicles of the exposed sheep.  They found abnormalities that could lead to infertility in 42% of the animals.

The effects varied from animal to animal, but could not be measured by blood testosterone levels or testicle size.
