【按：转基因农作物应用越来越广，危害的证据越来越多了。本文问：转基因作物引起动物不育的问题，政府管理者何时才想去面对？美国政府，何时才会面对和处理转基因导致动物不育的问题？也许是，等中国政府给转基因大米颁发合法证书以后吧？我好几年前就说过：美国的战略是：舍了孩子去打狼。不把中国领到悬崖下头，他们怎么能把转基因伤害动物的事端上台面呢？是几个动物重要，还是美国的21世纪生物技术的成功重要？孰轻孰重，一目了然。本文后面第一条跟帖：美国人必须从孟山都手中夺回自己的国家。中国亦然。打倒转基因法西斯，是一场全球性世界大战。转基因庄稼能让大鼠绝育，就绝不会让人好。定时炸弹，四下冒烟，转基因法西斯，日暮西山气息奄奄。】
来自埃及的研究：抗虫的转基因Bt玉米可致大鼠绝育
这里所说的发现来自2012~2013年间发表的三项研究，试验用的材料是孟山都公司的MON810抗虫转基因玉米品系的延伸品种。第一项研究表明，转基因玉米与其未转基因之前的亲本实质上不等同。第二项研究，用转基因玉米做饲料喂养大鼠，发现器官重量和体重有增有减，血液化学成分有变化，提示可能存在毒性。第三项是病理组织学研究，动物被饲以转基因玉米，对照组饲以非转基因玉米，结果清晰地显示器官组织出现病态，特别见于肝肾和小肠。此外还发生了精原细胞的坏疽(死亡)和剥落，精原细胞是形成精子的基础，因此导致雄性不育。这些现象都发生在短短91天的饲喂之后。
这是最近许多长期转基因玉米动物研究项目中最新的几项，有对照。这些研究提示转基因作物可能与啮齿类动物和农场动物的不育有直接关系。
2004年帕维亚大学做的研究，观察到转基因大豆饲料对小鼠生育的影响。草甘膦的问题也讨论过。
2010年“俄国国家基因安全学会”与俄国“生态与进化研究所”联合进行的研究显示，Cambell 仓鼠被饲喂转基因大豆两年后失去生育能力。
2012年，杰里.拉斯曼的长期观察表明，他养的猪因为转基因饲料玉米的缘故而不能生殖;出现了假孕、有的猪产下水囊。为此他转变成有机农民，只生产有机产品。
转基因作物引起动物不育的问题，政府管理者何时才想去面对？

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?
