Summary (though I highly recommend reading this)<p>1. Men's sperm counts have gone down by half in the last 30 years in industrialized countries, nobody has established why. [A]<p>2. The environment is full of (>1,400) endocrine-disrupting chemicals that may be an answer. One such example is Atrazine.<p>3. "We examined two doses of ATZ which included the 'safe' level for drinking water, determined by the Australian government, as well as a 10-fold higher dose delivered to the mice in drinking water from weaning until 12 weeks of age,"<p>4. "Our results showed significant effects on the reproductive and general health of male mice." Including reduced sperm count.<p>5. Interestingly, "We found a change in gene expression in the liver following ATZ exposure. Two genes implicated in fat uptake were found to be over-expressed, an early stage of 'fatty liver disease,"<p>6. Lower doses over a long exposure time may potentially do more damage than a high dose.<p>7. This study has been accepted for publication last month. The pair is continuing to do more research.<p>--

There is a fair amount of bad science about the risks of Atrazine and it's a shame that they referenced some of it (the negative effects on frogs haven't been replicated and there is significant evidence that the paper was not entirely honest about the facts). But of course, I'm not an expert to gauge the accuracy of this paper.<p>For those who are interested, it's likely that Alex Jones was referring to Atrazine with his "turning the frogs gay" rant (what he was referring to is the paper I mentioned, which claimed to find gonadal deformities in frogs that were exposed to Atrazine).<p>I'm not a chemist, but one has done a few videos on the topic of Atrazine[1].<p>[1]: <a href="https://youtube.com/watch?v=s6NDtIU8liw" rel="nofollow">https://youtube.com/watch?v=s6NDtIU8liw</a>
