Endangered Species: Shrinking Penis Sizes and Sperm Counts Threaten Human Reproduction


Some time ago we brought you a story about a global sperm bank that scientists want to build on the Moon. If the facility is built, it would house sperm and eggs from a large numbers of animal species, in addition to humans. But if they are serious about constructing the lunar sperm bank, they might want to hurry up. Otherwise there might not be functional human sperm left to store. The existence of humanity is facing an unprecedented threat. In just a couple of decades, our ability to make babies could be seriously hindered. Sperm counts in human males are falling drastically. Based on a 2017 study, human sperm counts have plummeted 59% between 1973 and 2011, reported Axios. “If you look at the curve on sperm count and project it forward — which is always risky — it reaches zero in 2045,” said the mentioned study’s co-author Shanna Swan, an epidemiologist from the Mt. Sinai Medical School. That means that in some 24 years, human males would become unable to produce viable sperm cells. We don’t need to tell you that it’s not good news for making new humans. “That’s a little concerning, to say the least,” said Swan, clearly aiming for the Understatement of the Year prize.
