Japan announced this week that as many as a third of 18-year-old women may never have children due to a 'sex recession' that has plagued the country for decades.

One out of every 10 Japanese men in their 30s is still a virgin, and the country's fertility rate has plummeted from 1.5 in 1992 to 1.34 births per woman in 2020.

The lack of babies being born is already having real-world impacts — Japan's economy has stalled and caused the country to lose its place as an economic superpower. 

And experts warn the US is barreling towards the same fate, with fertility rates at a historic low and an increase in sexless relationships.

As well as having one of the lowest birth rates in the world, Japan also has one of the highest life expectancies, meaning it is left with a rapidly aging society, a shrinking workforce and fewer taxpayers.
