Study: Household pollutants cause infertility in both men and dogs

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.
"We know when human sperm motility is poor, DNA fragmentation is increased and that human male infertility is linked to increased levels of DNA damage in sperm," said co-author Rebecca Sumner, postdoctoral student at the University of Nottingham, Britain.
"We now believe this is the same in pet dogs because they live in the same domestic environment and are exposed to the same household contaminants," Sumner said.
For the study, the team tested the effects of two man-made chemicals - the common plasticiser DEHP, widely used in the home (e.g. carpets, clothes, toys) and the industrial chemical polychlorinated biphenyl 153, which although banned globally, remains widely detectable in the environment, including food.
