Chemical pollutants in the home degrade fertility in both men and dogs, study finds

New research by scientists at the University of Nottingham suggests that environmental contaminants found in the home and diet have the same adverse effects on male fertility in both humans and in domestic dogs. 

There has been increasing concern over declining human male fertility in recent decades with studies showing a 50% global reduction in sperm quality in the past 80 years. A previous study by the Nottingham experts showed that sperm quality in domestic dogs has also sharply declined, raising the question of whether modern day chemicals in the home environment could be at least partly to blame.

In a new paper published in Scientific Reports, the Nottingham team set out to test the effects of two specific man-made chemicals namely the common plasticizer DEHP, widely abundant in the home (e.g. carpets, flooring, upholstery, clothes, wires, toys) and the persistent industrial chemical polychlorinated biphenyl 153, which although banned globally, remains widely detectable in the environment including food.
