Glyphosate Kills Rat Testis Cells

 Glyphosate Kills Rat Testis Cells

This does help reduce population. So, no one in the pesticide industry has

to worry about

losing their job. Monsanto controls the politicians, not the other way

around.

Glyphosate Kills Rat Testis Cells

#################################

Another link between Roundup and infertility. Dr. Eva

Sirinathsinghji

A new study finds that Monsanto’s glyphosate-based herbicide Roundup

Bioforce®

as well as glyphosate alone reduced testosterone levels in testicular cells

at

very low concentrations; and at higher concentrations - still 10 times

below

agricultural use – the cells died in 24-48 hours.

The study, carried out by Gilles-Éric Séralini and his colleagues at the

Université de Caen Basse-Normandie in France [1], was published just ahead

of

reports on glyphosate contamination of groundwater in Catalonia, Spain [2],

and

the presence of glyphosate in urine samples of Berlin city residents at

4-20

times the level allowed in drinking water (o.1 micrograms per litre, or 0.1

parts per billion (ppb)) [3]. American consumers exposed to glyphosate

through

residual levels in genetically modified (GM) foods are likely to have even

higher levels in their system; although no studies appear to have been

done.

These studies are emerging amid growing concern for the effects of

environmental

contaminants on decreasing levels of male fertility in humans and animals

in

industrialised nations [4], and there are already indications that

glyphosate

herbicide is linked to infertility and other reproductive problems.

Endocrine dysfunction at very low doses

Endocrine disruption can impact a wide range of physiological functions

that

include metabolism, growth and development,tissue function, behaviour,mood

and

reproduction. Healthy levels of testosterone in men are necessary for sperm

production among other things. With previous links of pesticides to

infertility,

the researchers were interested in whether glyphosate and its formulations

can

induce endocrine disruption in testicular cells.

The effects of Roundup Bioforce® and glyphosate alone were tested on three

types

of rat testicular cell: Leydig cells that produce testosterone, Sertoli

cells

that nurture germ cells through spermatogenesis, and germ cells that mature

into

sperm.

Doses of 1ppm (0.0001%) of both glyphosate and Roundup Bioforce® reduced

testosterone levels in Leydig cells by as much as 35 %, and a significant

increase in expression of aromatase was found within 24 hours. Aromatase is

an

enzyme that converts testosterone to oestrogens, and its activity is

important

for maintaining a healthy balance between the two hormones. These effects

of

supposedly ‘non-toxic’ dilutions of the herbicide underlie glyphosate’s

ability

to disrupt the endocrine system.
