Dogs struggling to give birth

Wednesday, August 10, 2016 (HealthDay News)- Fertility man’s dog In the UK over the last three decades, a new UK study suggests that chemical pollution may be the cause.

Researchers said the findings could shed light on reports of perceived declines in male fertility in many countries, including the United States, United Kingdom and France.

“This is the first time that such a decrease in male fertility has been reported in dogs, which is believed to be due to environmental pollutants, some of which have been detected in dog food and the sperm and testes of the animals themselves. “Research leader Richard Lee said. He belongs to the Faculty of Veterinary Medicine, Nottingham University.

According to background information from the new study, several reviews of human male childbirth have reported poor sperm quality and increased reproductive problems such as cryptorchidism over the last 70 years. However, the importance of these findings is still controversial, as different laboratories have used different methods over the years.

Nonetheless, the authors of the dog study said previous studies on men suggest that adverse environments affect the male reproductive system. And harmful exposures are thought to occur early in a man’s life, the researchers said.

Since dogs and men share a similar environment and a similar reproductive system, researchers thought that studying dogs might help provide some answers.

Researchers examined 26-year samples from five types of stud dogs at a breeding center in the United Kingdom. These varieties included Labrador Retrievers, Golden Retrievers, Curly Court Retrievers, Border Collies and German Shepherds. According to the study’s authors, sperm samples were taken from 42-97 dogs each year.

Researchers said they found a significant reduction in dog sperm quality during the study.

They also said they found that dog sperm and testes had levels of chemical contaminants that could harm sperm. These chemicals are also found in some pet foods, including brands for sale. puppy, The author of the study said.

Although a new study found a relationship between dogs infertility And exposure to chemicals, which did not prove cause and effect. However, the researchers said they tried to explain some other possible causes.

“We also considered other factors, for example, some genetic conditions affecting childbirth, but 26 years was ignored because the decline associated with genetic problems was too fast. “Lea said. Said in a college news release.

“While further research is needed to definitively show relevance, dogs can certainly be human sentinels. Dogs share the same environment, show the same range of illnesses, and often have the same frequency. And it reacts like a treatment. “He added.

The study was published online in the journal on August 9th. Science report..
