New tests conducted by British scientists show that widely used agricultural pesticides disrupt male hormones, and may be contributing to a suite of reproductive disorders increasingly common among men.

Reduced sperm count, infertility and abnormal genitals are among the problems some scientists have dubbed “testicular dysgenesis syndrome.” This latest study greatly strengthens the evidence that these problems may be linked to environmental contaminants.

Since 2008, Brazil has held the dubious distinction of spending more on pesticides than anyplace else on earth. But what has the country's farmers, public health professionals and environmental advocates even more worried is Brazil's corresponding rise in planting of genetically engineered (GE) crops, engineered to tolerate mega-doses of herbicides like glyphosate (Roundup). And these crops are driving emergence of herbicide-tolerant "superweeds".

Editor's note: This week, Environmental Health Perspectives selected this trio of studies for its 2012 "Paper of the year" award. EHP notes that the importance of the research to understanding the "alterations of cognitive function following developmental exposure to environmental chemicals." Congratulations to the study authors from all of us at PAN. We are reposting our original coverage of these studies below.

School-age children have lower IQs when their mother's are exposed to pesticides during pregnancy. This is the conclusion of 3 independent studies released today in the journal Environmental Health Perspectives.

In an apparent, and failed, attempt at self-defense, honey bees are sealing off pesticide-laced pollen.

U.S. entomologists published a study two years ago that described a newly observed phenomenon in honey bees, now known as entombed pollen: food stores sealed off by bees after being deposited in the hive. That pollen was much higher in pesticide residues than any other pollen stored in the hive, and correspondingly had no detectable bacteria or fungi. Hives with entombed pollen were more than twice as likely to collapse later in the season than hives without it.
