【按：轉基因農作物應用越來越廣，危害的證據越來越多了。本文作者問：轉基因作物引起動物不育的問題，政府管理者何時才想去面對？美國政府，何時才會面對和處理轉基因導致動物不育的問題？也許是，等中國政府給轉基因大米頒發合法證書以后吧？我好幾年前就說過：美國的戰略是：舍了孩子去打狼。不把中國領到懸崖下頭，他們怎么能把轉基因傷害動物的事端上臺面呢？是幾個動物重要，還是美國的21世紀生物技術的成功重要？孰輕孰重，一目了然。本文后面第一條跟帖：美國人必須從孟山都手中奪回自己的國家。中國亦然。打倒轉基因法西斯，是一場全球性世界大戰。轉基因莊稼能讓大鼠絕育，就絕不會讓人好。定時炸彈，四下冒煙，轉基因法西斯，日暮西山氣息奄奄。】
來自埃及的研究：抗蟲的轉基因Bt玉米可致大鼠絕育
這里所說的發現來自2012~2013年間發表的三項研究，試驗用的材料是孟山都公司的MON810抗蟲轉基因玉米品系的延伸品種。第一項研究表明，轉基因玉米與其未轉基因之前的親本實質上不等同。第二項研究，用轉基因玉米做飼料喂養大鼠，發現器官重量和體重有增有減，血液化學成分有變化，提示可能存在毒性。第三項是病理組織學研究，動物被飼以轉基因玉米，對照組飼以非轉基因玉米，結果清晰地顯示器官組織出現病態，特別見于肝腎和小腸。此外還發生了精原細胞的壞疽(死亡)和剝落，精原細胞是形成精子的基礎，因此導致雄性不育。這些現象都發生在短短91天的飼喂之后。
這是最近許多長期轉基因玉米動物研究項目中最新的幾項，有對照。這些研究提示轉基因作物可能與嚙齒類動物和農場動物的不育有直接關系。
2004年帕維亞大學做的研究，觀察到轉基因大豆飼料對小鼠生育的影響。草甘膦的問題也討論過。
2010年“俄國國家基因安全學會”與俄國“生態與進化研究所”聯合進行的研究顯示，Cambell 倉鼠被飼喂轉基因大豆兩年后失去生育能力。
2012年，杰里.拉斯曼的長期觀察表明，他養的豬因為轉基因飼料玉米的緣故而不能生殖;出現了假孕、有的豬產下水囊。為此他轉變成有機農民，只生產有機產品。
轉基因作物引起動物不育的問題，政府管理者何時才想去面對？

GM Bt Corn Causes Infertility in Rats – New Egyptian Studies

Egyptian researchers have found that Bt corn is not substantially equivalent to non-GM parent and was toxic to rats, even after only 91 days of feeding.
These findings arose from three studies published in 2012 and 2013 on a type of GM insect resistant Bt corn developed using Monsanto’s MON810 trait.
One study showed that the GM corn was not substantially equivalent to the non-GM parent.
A second study examined the effects on rats of a diet containing the GM maize. The study found that the GM corn diet caused increased or decreased organs/body weight or changes in blood biochemistry that indicated possible toxicity.
In the third study, histopathological examination was carried out on the rats fed the GM maize, and the results were compared with rats fed non-GM maize. The study found clear signs of organ pathology in the GM-fed group, especially in the liver, kidney, and small intestine. An examination of the testes revealed necrosis (death) and desquamation (shedding) of the spermatogonial cells that are the foundation of sperm cells and thus male fertility – and all this after only 91 days of feeding.
These studies are the latest in a long line of studies and in-field cases that suggest GM crops could be linked directly to infertility in rodents and farm animals.
In 2004 research carried out at the University of Pavia considered the possible effects of a diet containing genetically modified (GM) soybean on mouse testes. Changes that could cause infertility problems in the mice testes were identified and the role that glyphosate could have caused in this was also discussed in the research findings.
In 2010 an experiment carried out jointly by the Russian National Association for Gene Security and the Institute of Ecological and Evolutional Problems showed that Campbell Hamsters lost the ability to reproduce after being fed GM soy for 2 years.
In 2012 after long research, Jerry Rosman discovered his pigs couldn’t reproduce because of genetically engineered corn. They produced sacs of water—false pregnancies. As a result, he’s become an organic farmer and proponent of organic foods.
Is it not about time for government regulators to look at the possible links between GM Crops and infertility?
