Two recent studies
show Roundup to be an endocrine-disruptor and to be associated with
birth defects in humans who work with it.
Farmers who applied pesticides to their crops in Minnesota were
studied, along with their families, to see if their exposure to
pesticides caused birth defects in their children. The study found
that both fungicides and the herbicide Roundup were linked to statistically
significant increases in birth defects. Roundup was linked to a
3-fold increase in neurodevelopmental (attention deficit) disorders.

A test tube study also reported in the journal Environmental Health
Perspectives showed that Roundup can severely reduce the ability
of mouse cells to produce hormones. Roundup interferes with a fundamental
protein called StAR (steroidogenic acute regulatory protein). The
StAR protein modulates the production of testosterone in men (thus
controlling male characteristics, including sperm production) as
well as the production of adrenal hormone (essential for brain development),
carbohydrate metabolism (influencing loss or gain of weight), and
immune system function. The authors write that "a disruption
of the StAR protein may underlie many of the toxic effects of environmental
pollutants." (Environmental Health Perspectives Vol. 108, No.
8 (August 2000), pgs. 769-776.)
