What does it mean that the sperm count among Western men has shrunk by half since the ‘70s?

‘The good news is that 47.1 million sperm per milliliter is still pretty healthy. A person’s sperm count is considered “low” when he has fewer than 15 million sperm per milliliter of semen, and plenty of men with low sperm counts are still able to conceive children. Future studies should examine whether there has been a corresponding increase in men clocking in below the 15 million sperm threshold in addition to a general decrease in average sperm concentration. More good news: There are research-based behavioral changes men can make to combat sperm-count decline, such as quitting smoking, eating healthy meals, and avoiding food and drink that have touched pesticides or materials containing BPA.

 

The bad news, according to Levine, is that the new study’s results may foretell “the extinction of the human species” if we don’t figure out what’s causing the lack of sperm and take action…’
