Environmental contaminants found in home and diet have the same adverse effects on male fertility both in humans and domestic dogs, finds a new study highlighting the decline in sperm quality in both the species over the past few years.
The findings, published in the journal Scientific Reports, showed the chemicals — at concentrations relevant to environmental exposure — have the same damaging effect on sperm of both man and dog. The researchers carried out identical experiments for both species using samples of sperm from donor men and dogs.
