Genetically modified plants afectt fertility?
Yes genetically modified plants affect the fertility. This has been proved by along-term feeding of genetically modified corn or maize by the Austrian government. According to the Austrian government mice had fewer offspring and lower birth rates. Most of the research on genetically modified crop safety has been conducted by biotech companies, such as Monsanto, rather than outside independent laboratories.
According to Professor Dr Jurgen Zentek, Professor for Veterinary Medicine at the University of Vienna and lead author of the study, said a genetically modified diet effected the fertility of mice.
According to Dr Jan van Aken, GM expert at Greenpeace International, says that genetically engineered food appears to be acting as a birth control agent, potentially leading to infertility. Prof Zentek said there was a direct link between the changes seen and the genetically modified diet. A press release from the Austrian Agency for Health and Nutrition, said the group of mice given a diet of genetically engineered corn saw a significant change in fertility.
A study presented by the Austrian Ministry of Agriculture and Health, in a scientific seminar held in Vienna, indicates that genetically modified organisms can affect reproductive capacity and therefore specialists require the withdrawal of these products .
The study indicates that fertility of laboratory mice, fed with genetically modified maize, was seriously affected,they procreating only a little, compared with those fed with natural food.
Laboratory mice fed with food that did not contain genetically modified organisms were reproducing more efficiently. This effect can be attributed to differences in sources of food.
Austrian scientists have carried out several long-term tests with laboratory mice, along 20 weeks. In one study, which was called "reproductive assessment by continuous feeding ",it was shown that a single generation of parents gave birth to several offsprings.Parents were fed either diet containing 33% proportion of different types of genetically modified corn (NK 603 x MON 810) or non-GM maize. In laboratory mice receiving genetically modified food was a decrease in the number of pups and their weight at the third and fourth generation, compared with the reference group. This decrease is statistically significant, said study authors.
This study is another example that the safety of food and feed derived from GM crops can not be guaranteed.
