Falling sperm count observed around the world, study finds
Men aren’t producing as many sperm as they were decades ago. It’s a trend observed around the globe. The pace of decline is accelerating.
Men aren’t producing as many sperm as they were decades ago. It’s a trend observed around the globe. The pace of decline is accelerating.
Those are the headline findings of a new analysis of sperm count studies published Tuesday in the journal Human Reproduction Update. It’s the largest report to examine the issue.
In a news release, the researchers behind the analysis framed their findings as a “looming crisis” and a “canary in a coal mine” that could “threaten mankind’s survival.”
Shanna Swan, an author of the new analysis, said in an interview that the new research should sound alarms about men’s overall health and reproductive fitness.
“There is a decline in reproductive function,” said Swan, a professor of environmental medicine and public health at the Icahn School of Medicine at Mount Sinai in New York City. “This is not an isolated phenomenon.”
