Roundup® damages testicle cells, lowers testosterone

Most men don’t know that their testosterone levels are significantly lower than their grandfathers at the same age. Or that those levels are declining faster and sooner than their grandfathers did. In the late 1940s, 1950s and 1960s it wasn’t at all unusual to find a strong testosterone level in a man in his 60s; in 2012, it’s definitely an unusual finding.

It’s a little better known that fertility problems have been steadily increasing, especially in the last two or three decades. As is the case with testosterone levels, sperm counts are generally lower in the ‘average man’ in the 21st century than in the 1950s.

For decades we’ve know that many of the herbicides and pesticides used in farming (except organic farming) are – for humans – ‘environmental oestrogens’. These molecules imprecisely mimic the activity of oestrogen. As ‘space alien’ molecules never before found on planet Earth – remember, all commercial herbicides and pesticides are (or were) patented – they don’t belong in human bodies, and cause trouble when they’re consumed in food or water. In fact, environmental oestrogens are suspected to be part of the reason for lower testosterone levels and lower sperm counts in each generation (or perhaps we should call it each degeneration) of American men since the 1950s.

GMO agriculture has opened a brand-new front in the chemical war on men’s testosterone and sperm counts.

The abstract below, taken verbatim [with translation in brackets] from research published in 2012, makes it perfectly clear that glyphosate, a principal active ingredient in the chemical spray Roundup®, is toxic to testicle cells – even killing them – and significantly lowers testosterone synthesis.

“Roundup is being used increasingly… on genetically modified plants grown for food and feed that contain its residues. Here we tested glyphosate and its formulation on mature rat fresh testicular cells from 1 to

10,000 parts per million… the range [found] in some human urine and in the environment… We show that from 1 to 48 hours of Roundup exposure Leydig cells [the testicular cells which make testosterone] are damaged. Within 24-48h this [Roundup®] formulation is also toxic on the other cells, mainly by necrosis [cell death], by contrast to glyphosate alone which is essentially toxic on Sertoli cells [testicular cells which make sperm]. Later, it also induces apoptosis [cell suicide] at higher doses in germ cells and in Sertoli/germ cells co-cultures. At lower… concentrations of Roundup and glyphosate (1 part per million), the main endocrine disruption is a testosterone decrease by 35%. The pesticide has thus an endocrine impact [lower testosterone levels and sperm counts] at very low environmental doses, but… a high contamination appears to provoke an acute rat testicular toxicity [cell death].1

Remember, men! It’s not just the Roundup® that is sprayed on lawns that may impair your virility, it’s the Roundup® residue found on the GMO foods eaten every day – yes, those tiny amounts – that can kill testicle cells and lower testosterone.

Corn chips, anyone?
