High Prevalence of Proposed Müllerian Duct Remnant Cysts on the Spermatic Duct in Wild Eurasian Otters from Sweden

A 2013 study looked at the spermatic ducts (vasa deferentia) of 235 otters (Lutra lutra) found dead between 1999 and 2012 in Sweden were examined for presence of paraductular cysts. The possible causes of the incomplete regression of the embryonic female gonadal duct are exposure to environmental contaminants such as elevated concentrations of estrogen-like compounds (endocrine disrupting chemicals), inbreeding, or a naturally occurring anatomic defect.The present finding of the proposed Müllerian duct remnants could indicate that these otters were exposed to elevated concentrations of estrogens or estrogenic like compounds during fetal development.

Parabens Used in Cat & Dog Food

2018 study researchers found dry pet food contained higher levels of parabens than wet food and that cat food used more of the hormone disruptor than dog food.

Effects of Pollutants on the Reproductive Health of Male Vertebrate Wildlife

Hormone Disrupting Chemicals Linked to Reproductive Issues in Male Otters

A report from CHEMTrust on chemicals linked to decrease in the otters penis bone, undescended testicles and an increase in cysts on reproductive tubes.

Intersex Fish Now in Three Pennsylvania River Basins: USGS

A 2014 news releasae by the U.S. Geological Service (USGS) finds intersex fish have been found in Pennsylvania’s Susquehanna, Delaware and Ohio river basins, indicating that the effects of endocrine-disrupting chemicals are more widespread than previously known. 

Canine Toys and Training Devices as Sources of Exposure to Phthalates and Bisphenol A: Quantitation of Chemicals in Leachate and in Vitro Screening For Endocrine Activity

A 2013 study looks at how chewing and mouthing behaviors exhibited by pet dogs are likely to lead to oral exposures to a variety of environmental chemicals. Products intended for chewing and mouthing uses include toys and training devices that are often made of plastics. The goal of the current study was to determine if a subset of phthalates and bisphenol A (BPA), endocrine disrupting chemicals commonly found in plastics, leach out of dog toys and training devices (bumpers) into synthetic canine saliva. These results confirm that toys and training devices are potential sources of exposure to endocrine disrupting chemicals in pet dogs.
