During the periods of higher air pollution sperm quality went down significantly. When the air quality improved, so did the quality of the sperm.
The study authors said this suggested that the pollution was affecting mature sperm late in their development, damaging the DNA.
This falls firmly under my "things that are only going to get worse" list.

Oh well.
We have too many people as it is.
Personally I take hot, hot showers and wear tight hot binding underwear, to kill my boys.
Cap'n--
Keep up the good work. ;-)
