The research team discovered this effect when studying high-level male athletes, who often take the highest doses of ibuprofen to treat and prevent muscle pain. This is especially bad news for The Guys, who are high-level drinking athletes — we already can’t take acetaminophen.
Researchers are now investigating what introduced these chemicals into the dogs and whether the same sources could also be causing low quality human sperm development. (Well, not us specifically. The Guys regularly submit samples to measure Guyness and root out comedy performance-enhancing drugs.)
But, until we know what’s happening for sure, you should probably reassure your dog that he is, in fact, a good, masculine boy.
