What Dog Testes Tell Us About Human Fertility

Fact-Checked Can Fido teach us about fertility? Since they have similar reproductive systems, share an environment with us, and are exposed to the same toxins as their owners, scientists consider dogs a sentinel species.   David Prado/Stocksy In the early 1900s, coal miners used birds in cages to monitor air safety and alert them when they were inhaling noxious gas while they could still act to save themselves. Today, researchers are studying pet dogs to learn about the chemicals that men are exposed to at home in search of warning signs that human health may be at risk. New Study Looked at Dogs, Rather Than Birds, for Early Signs of Toxicity

How plastics are making us infertile — and could even lead to human extinction

comments Climate change is rightly cited as an environmental crisis that could lead to human extinction. Yet there is another pollution issue, indirectly related, that could make it literally impossible for human beings to reproduce. I am talking, of course, about plastic pollution. Advertisement: Dr. Shanna Swan, a professor of environmental medicine and public health at Mount Sinai school of medicine in New York City, has a new book out called Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race. In it she describes how various chemicals commonly found in plastic products are leading to a decline in fertility. The most striking example of this is in dropping sperm counts; if you have fewer than 15 million sperm per milliliter of semen, you are considered to have a low sperm count. Human beings are rapidly reaching that point, as Swan demonstrates in her book.
