Add falling sperm counts to the list of threats to human survival, epidemiologist warns
"Chemicals in our environment and other lifestyle factors in our modern age have harmed our reproductive health to the extent that, in the future, it may not be possible for most people to reproduce in the old-fashioned way," said Shanna Swan, an environmental and reproductive epidemiologist at the Icahn School of Medicine at Mount Sinai in New York with more than four decades of experience in the field.
Sperm counts among men in North America, Europe, Australia and New Zealand declined more than 59% from 1973 to 2011, according to a meta-analysis Swan co-wrote in 2017. At the current rate, half of men in those countries would have no sperm by 2045, while many others would have very low counts, Swan told USA TODAY.
Dear, oh dear. Who knew we'd inadvertently develop our very own population controls? I guess it's inevitable. Microbes and chemicals. As long as we collectively have the hubris to believe we can control and exploit nature, this is humanity's road.
