“The possibility of a link between air pollution and semen quality has been suggested in a number of studies over the years, although not all of them have agreed with this conclusion,” said Allan Pacey, professor of andrology at the University of Sheffield, who was not involved in the research.
Research into samples of 30,000 men in China suggests ability of sperm to swim in right direction could be affected.

Air pollution may affect semen quality, specifically sperm motility — the ability of sperm to swim in the right direction — according to a new study analysing the sperm of over 30,000 men in China.
The research, published today in the journal JAMA Networks, also suggests that the smaller the size of the polluting particles in the air, the greater the link with poor semen quality.
It’s everywhere: in the rain, snow, our food, our waters, even in the human placenta! Mercury is poisoning life on Earth.
ARE YOU AWARE artisanal miners' gold ore processing produces 20% of the world's supply of gold used in our jewellery, iPad’s, iPhone, computers, and other electronics devices?
Artisanal miners' ore processing uses mercury, a deadly neurotoxin to extract gold from crushed or milled ore releasing 2,000 tonnes of mercury vapor to our atmosphere annually and is the world's largest anthropogenic source of deadly mercury pollution overtaking coal fired plants mercury emissions in 2017.
Mercury pollution is documented in 2021 by Oxford University earth scientists to stay airborne up to one year then precipitates back to Earth in the form of rain and snow.
But finally there's hope"
