Sperm counts worldwide have plummeted by 62 percent since 1973, according to new Israeli-led research.
The study sounds alarm bells for both male fertility and for male health in general, its authors said. This is because low sperm count is considered an indicator of men’s health, with low levels being associated with an increased risk of chronic disease, testicular cancer, and a decreased lifespan.
“We should be amazed and worried by the finding,” said Prof. Hagai Levine of the Hebrew University of Jerusalem, who led the peer-reviewed study together with Prof. Shanna Swan at New York’s Icahn School of Medicine.
“The trend of decline is very clear,” told The Times of Israel. “This is a remarkable finding and I feel responsible to deliver it to the world. The decline is both very real and appears to be accelerating.”
