"Between 1989 and 2005, average sperm counts fell by a third in the study of 26,000 men, increasing their risk of infertility. The amount of healthy sperm was also reduced, by a similar proportion.

The findings confirm research over the past 20 years that has shown sperm counts declining in many countries across the world. Reasons ranging from tight underwear to toxins in the environment have been advanced to explain the fall, but still no definitive cause has been found."

I wonder if there could be some sort of "internal regulation" of sperm production because the need, desire and request to reproduce is substantially lower now then it was 1-3 generations ago in most modern countries but also for example in China (one-child laws).

It's Gaia trying to get back in balance. Gaia will continue to put the squeeze on sperm count until equilibrium is reached.:thumb:

The best evidence today is that toxins in the environment are responsible. (endocrine disruptors, et al:

HEIDELBERG, 12 May 2014 – A plethora of endocrine-disrupting chemicals interfere with human sperm function in a way that may have a negative impact on fertilization. These are the findings of a German - Danish team of researchers ....“For the first time, we have shown a direct link between exposure to endocrine disrupting chemicals from industrial products and adverse effects on human sperm function,’’ said Niels E. Skakkebaek, professor and leader of the Danish team.

And in China:


Li Zheng, told local newspapers that he was “very worried” about the falling quality of sperm, and that two-thirds sperm at Shanghai’s main bank did not meet standards set by the World Health Organization.
A 2012 study, coordinated by Dr Li, concluded that over the last 10 years worsening environmental conditions had closely mirrored the falling quality of sperm. Low sperm counts and aspermia, a condition that causes a man to produce no semen at all, were among the problems.

So much more to worry then the shrinking of the Y-chromosome reported multiple times as problem in the last decades (IMHO unsubstantiated).

Other evidence found the same problems in Europe, the US, and Israel, so the problem is world-wide.

Even at very low concentrations, this chemical [Ethinyl estradiol (EE2), the main active ingredient of contraceptive pills] has harmful effects on fish. Males suffer reduced sperm production, with severe effects on populations. In one recent trial, in a Canadian lake, researchers added EE2 until levels in the water reached five parts per trillion (ppt), a minute concentration. Yet fish populations suffered severe problems with one species, the fathead minnow, collapsing completely.

Essentially, the main ingredient in contraceptive pills EE2 damages male reproductive systems.
