The Hebrew University/Mount Sinai paper was a meta-analysis by a team of epidemiologists, clinicians, and researchers that culled data from 185 studies, which examined semen from almost 43,000 men. It showed that the human race is apparently on a trend line toward becoming unable to reproduce itself. Sperm counts went from 99 million sperm per milliliter of semen in 1973 to 47 million per milliliter in 2011, and the decline has been accelerating. Would 40 more years—or fewer—bring us all the way to zero?
1 - I want to know who the test subjects actually were.
2 - Boys and young men today are lazier, more sedentary and less active, than they have ever been. They have great thumb muscles from playing video games, but their bodies are weak. Remember, 7 out of 10 high school graduates are unfit for military service, due to criminal activity, drug use, or being so completely out of shape that we cannot send them to basic training. It stands to reason that boys who aren't active, not building muscle, and not doing more than moving from the chair to the fridge and back won't be producing much testosterone.
3 - Speaking of drug use: We have rather high rates of marijuana use. THC effects the brain. The glands that signal for the production of testosterone are where? In the brain. Studies have also shown that prolonged marijuana use can lower your sperm count. In short, it messes with your testicles. Where is testosterone produced? In your testicles.
The article traces the problem back down to plastics, and how much of them are ingested by humans. Why take chances? If you have boys, get them off the couch pronto, and don't let them smoke weed. And then work on overall health. Stop eating crap. Learn how to cook real food. Read labels. If you can't pronounce it, you probably don't need to be eating it.
But in the end, we're all gonna die. The only real question is how you want to live.
