" For the males, decreased sperm count and enlarged prostates. The treatment altered virtually every aspect of the reproductive system. The place next to the testes, the duct system called the epididymis where the sperm are stored prior to being ejaculated -- it was abnormally small, which could account also for lowered sperm count in the ejaculate. But we know also the testis is making fewer sperm. We see changes in growth rate as well. One of the interesting things is that these very low doses of estrogen increase rates of growth. The animals were actually growing larger than they would have normally. It was really quite a dramatic effect. The females went into puberty early. And we saw changes in behavior, changes in reactivity to the presence of other animals in the environment. Essentially the animals looked to be somewhat hyper-reactive to stimuli. We have, in other words, effects on brain and behavior. We're also seeing changes in liver enzyme activity which determines the way we respond to external chemicals, how fast we clear drugs, how we metabolize drugs. In other words, in every aspect of physiology that we look for, we see effects. And they're permanent. And the important thing about what I'm talking about is we are only exposing babies to these chemicals for very, very short periods of time in development and the consequences are for the rest of the life of that individual. Once you change the development of an organ there is no way to undo that effect. It's a life sentence -- that's a lifetime consequence. Medical science can't undo the development of organs. " Fredrick Vom Saal, Professor of Biological Sciences, University of Missouri in an interview on estrogenic chemicals in the environment conducted in February 1998 by Doug Hamilton, producer of FRONTLINE's " Fooling With Nature. " Full interview can be found here From simple laboratory mice to the unusual case of the phytoestrogen sensitive captive cheetahs, there is ample evidence that dietary phytoestrogens cause infertility in a variety of animals. Why would this be? Like the other toxins in soybeans, the phytoestrogens are present in the soybean to ensure its survival. What better way to discourage predators than to make sure they aren't able to reproduce? But what about humans? Some, such as Richard Sharpe and Theo Colborn, have suggested that the trend toward lower male fertility is due to environmental estrogens, including the soy phytoestrogens. But is there any evidence that phytoestrogens may place males at risk of reduced fertility? Also see quotes from Food Safety - a 21st Century Issue, by Professor Shaw in the New Zealand Science Review. The human sperm count decrease over the past five decades might relate to the introduction of soya to the western diet and the increasing popularity of vegetarianism - a sting in the tail for apparently healthy eating. More information is available from an article published in The Dominion, Wellington September 3 2001. Nagata and colleagues have reported an inverse association between soy product intake and serum hormone concentrations in Japanese men. Research has demonstrated that chemical compounds can have a number of other effects on male health including decreasing prostate gland weight, lower testosterone levels, along with inducing significant testicular cell death and necrosis. §*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§*§ *§ - PULSE ON WORLD HEALTH CONSPIRACIES! §* Subscribe:......... - Quote Link to comment Share on other sites More sharing options...

This and other articles you have posted (that I've seen) have been excellent. Please keep up the good work. Gary. Quote Link to comment Share on other sites More sharing options...
