‘Spermageddon’: is the world facing a male reproductive crisis?

Article here. Excerpt:

'The world is unwittingly walking into a male reproductive crisis, scientists warned this week as they presented data that revealed an apparent halving of average male testosterone levels over the past 50 years.

“It is mind-blowing that testosterone has declined by 50%,” Prof Hagai Levine, who led the work, told the Guardian. “This is a lot. Wake up people. Wake up.”

The finding is the latest in a series of recent results that suggest male fertility is in crisis. Levine’s team has previously documented an apparent drastic decline in global sperm counts, in what has come to be known as the “spermageddon” paper. The issue has become a preoccupation across the political spectrum.

The US health secretary, Robert F Kennedy Jr, has called declining sperm counts an “existential crisis” and Levine’s work has been seized on in the “manosphere” as proof modern society is emasculating men. The findings have also galvanised concerns about the hazardous impact of endocrine-disrupting chemicals, air pollution and global heating on human health.'
