Fertility could reach 0 in 20 years

Shanna Swan, a leading fertility researcher and professor of environmental medicine, has documented sharp declines in human fertility due to phthalate (soft plastic) and other chemical exposures. In 2017, she noted that sperm counts in Western men had fallen by half in the past 40 years.

From the article:

"If you follow the curve from the 2017 sperm-decline meta-analysis, it predicts that by 2045 we will have a median sperm count of zero. It is speculative to extrapolate, but there is also no evidence that it is tapering off. This means that most couples may have to use assisted reproduction."

I was telling my wife this morning that, in just my lifetime, China has gone from having a one-child policy due to overcrowding to worrying about population decline. Astonishing.
