Interested in potential causes for this. Our polluted cities? Just stress? Bad diet?
Environmental pollutants? Endocrine disruptors? Internet porn?! Most of us are probably eating healthier than 40 years ago (Heart disease is way down), so not sure it's diet. Unless of course its all the chemicals and contaminants that we're getting with our food...
basic biology, plenty of hormones floating around so you're not so essential to the survival of the species.
yeah right.. evolution observed in the tiny span of time that is recorded modern science?
I've personally become concerned recently with the abundance of BPA and it's effect on the endocrine system of men. Between disposable water bottles, aluminum can liners, and food stored in plastic containers, there's a huge amount of exposure to this endocrine disruptor. The article doesn't mention it in particular, but I think it's worth being cautious over.

Got any links to research?

In addition, the analysis appears to deal with the mid 1970s onward, whereas Bisphenol A has been used commercially to cure resins and plastics since 1957, with a quick uptake in usage. We would have to look at the trend further back to have a lede on that, because the recent clinical data are not sufficient to support the claim that normal Bisphenol A exposure (and this is assuming it increased dramatically over this period) can be linked directly with a fifty to sixty per cent reduction in sperm count and/or quality.
There are studies linking overweight and obesity to reduced sperm count, and overweight/obesity rates have increased dramatically and steadily over the measured period of time. Unfortunately, this meta analysis did not appear to address these factors.
All of that said, Bisphenol A is very risky stuff, we should be very careful with the amount of it in the environment and our bodies.
