The University of Nottingham published a report on dog fertility in August 2016. After analyzing fertility in stud (male) dogs over a 26 year period, the university noted a significant decline in semen quality.
Given the overpopulation of animals shelters in the US, isn't there some silver lining here? Unfortunately no, as the decline in dog fertility is synonymous with ailing dog health.
The University of Nottingham observed "environmental contaminants" in the sperm and testes of adult dogs, resulting in lower fertility: "[we] were able to demonstrate that chemicals found in the sperm and testes of adult dogs - and in some commercially available pet foods - had a detrimental effect on sperm function at the concentrations detected."
Simply put, domesticated dogs are exposed to more chemicals today than ever before - whether it is in dog food, drinking water, or other environmental components (i.e. pesticides used on plants and grass) - and this is causing a buildup of toxins in their reproductive organs and hurting their ability to reproduce.
The scary part? Researchers have observed a similar decline in adult human sperm quality and function.
Could it be that we are exposing ourselves to the same toxic chemicals that are hurting our furry friends? Jury's still out, but all evidence suggest this is the case.
