New research finds chemicals in the home are linked to reduced male fertility in dogs and humans. University of Nottingham researchers analyzed the effects of chemicals PCB153 and DEHP on male fertility in humans and dogs.
DEHP is a common plasticizer found in many household items, including shower curtains, garden hoses, shoes and swimming pool liners. PCB153, which is banned internationally, can still be detected in the environment.
The scientists say sperm motility in humans and dogs has declined by 30% over a 26-year period.
