A prolonged decline in male fertility in the form of sperm concentrations appears to be connected to the use of pesticides, according to a study published Wednesday.

Researchers compiled, rated and reviewed the results of 25 studies of certain pesticides and male fertility and found that men who had been exposed to certain classes of pesticides had significantly lower sperm concentrations. The study, published Wednesday in Environmental Health Perspectives, included data from more than 1,700 men and spanned several decades.

“No matter how we looked at the analysis and results, we saw a persistent association between increasing levels of insecticide and decreases in sperm concentration,” said study author Melissa Perry, who is an environmental epidemiologist and the dean of the College of Public Health at George Mason University. “I would hope this study would get the attention of regulators seeking to make decisions to keep the public safe from inadvertent, unplanned impacts of insecticides.”

    It’s purely anecdotal, but go to a small town in Iowa and you may notice something a little unexpected - there’s seemingly a larger than normal population of gay and transgender people.

    Again, anecdotal, but I visit there frequently for work. My gut tells me the crop treatments are screwing with hormones…unless there’s some other explanation.

        People mock the gay frogs thing, but pesticide runoff was mucking with frog hormones, causing a genuine physical sex shift. Frogs are capable of shifting sex under specific conditions, and the chemical pollution was forcing the change. Huge ecological damage.

        It was perhaps the single time alex jones was correct about anything, and if he hadnt called the frogs gay he probably wouldnt have been mocked for it.
