Study Shows that Environmental Chemicals Impact Dog Semen Quality

Environmental Chemicals Impact Dog Semen Quality – Duh!

Here is an interesting report on a population of breeding dogs exhibiting a 26 year (1988–2014) decline in sperm quality and a concurrent increased incidence of cryptorchidism in male offspring (1995–2014). A decline in the number of males born relative to the number of females was also observed.

Environmental chemicals (ECs), including diethylhexyl phthalate (DEHP) and polychlorinated bisphenol 153 (PCB153), were detected in adult dog testes AND (get this:)  commercial dog foods at concentrations reported to perturb reproductive function in other species.

Testicular concentrations of DEHP and PCB153 perturbed sperm viability, motility and DNA integrity in vitro but did not affect LH stimulated testosterone secretion from adult testis explants. The direct effects of chemicals on sperm, may therefore, contribute to the decline in canine semen quality that parallels that reported in the human.

DEHP is an industrial chemical used in vinyl-type plastics to make them soft and pliable. DEHP is in perfume, hair spray, most all fragrances, shampoo, air fresheners, laundry detergent, dryer sheets, insect repellents, pesticides, plastic toys, bowls, etc.

PCB153 or all PCBs for that matter are present in most all manufactured products from flame retardants, pesticides, electrical equipment and much more.

PCBs are known to cause cancer and damage to the reproductive, endocrine, immune, and nervous systems. In addition, PCBs damage the kidney and gastrointestinal tract and cause birth defects.

  1. How can we avoid these chemicals?

    • Hi Alica! While easy,it is not something many people or dog breeders are willing to do. We can avoid many of these of toxic chemicals by avoiding the use of toxic chemical-based household cleaners and personal products, feed a raw species appropriate diet – preferably feeding grass-fed, pasture raised animals, etc. I JUST posted an article on environmental estrogens(toxins that were listed in this article) Thank you for your question. 🙂
