CNN has published an article asking why testosterone and sperm counts are plummeting across Europe and North America, saying that if sperm was an animal it might be "heading toward extinction in western nations."

The article highlights how "Total sperm count in North America, Europe, Australia and New Zealand dropped by up to 60% in the 38 years between 1973 and 2011" and that more recent research shows the trend is continuing.

The article links the fall to diets made up of fatty and processed foods, but admits "no one knows for sure" the reason and that it could also be connected with "radiation, air pollution and chemicals in our food, clothes and water."

The article opens with, "If sperm was an animal, science might worry that it's heading toward extinction in Western nations," a line which if it was uttered by a right-winger would be taken by many in the media as a dog whistle for white supremacy.
