Which frogs can change their gender and how?

Tap Water Cause Frogs to change gender, what may it do to men?

  • According to an new study a poison or contaminant found in tap water have caused some male frogs to turn female. They even produce eggs. http://www.usatoday.com/tech/science/2010-03-02-1Aatrazine02_ST_N.htm What I ask is, why would the government allow this? And please dont tell me that our govt wont do that to its own people. Why? Because we are Amercans? Thanks for you answers. Read the article if interested and do your own research.

  • Answer:

    I knew that they put stuff in the water, for I have been potitioning our congress about it for years (With little result, I might add.) I didn't know that it was causing gender changes in frogs though. That may explain why I've had the sudden urge to wear womens shoes recently....LOL!!

of course they would poison us what do you think western medicine is, it's the sole reason we cannot naturally recover from aids and cancer

This is a perfect example of why we are in this deep financial and economic crisis - spending hundreds of millions of dollars to dunk frogs into tap water. This is useless information that will never benefit anybody, ever. Still, the stupid government keeps spending money hand over fist (money it does not have) for idiotic things like this and other useless things, like turtle tunnels under highways. It's not that the government allows this, the government DOES it. Government is always the problem, never the solution.

Sometimes things have unintended consequences. They (the FDA) tested the atrazine, but apparently didn't test it with multiple exposures (like the frogs would encounter in real life). The recommendation at the bottom of the article say it should be phased out. Some men have low sperm counts these days. Perhaps it is related to a lifetime of low level atrazine exposure.

I bet they spent millions of dollars poisoning frogs, they call it a stimulus bill. You kind of spun that article didnt you? They didnt expose frogs to tap water, they exposed the frogs to a single dose of chemical herbicide directly. Also, any household tap water filter is fully capable of removing the chemical. The EU has banned the chemical all together. But also dont forget humans are a higher form of life. All wild male rabbits die "naturally" of prostate cancer because of high sperm production due to their reproduction rates. Thats like saying male pornstars will die fo prostate cancer bc of too much sex. We`re a higher form of life. Now if they tested the chemical on monkeys or pigs then that`d be something to write home about.

herbicide that contaminates the tap water consumed by millions of Americans has been found to produce gender-bending effects in male frogs, "chemically castrating" some and turning others into females, a study shows. Frogs in the experiment were exposed to amounts of the weedkiller atrazine that are comparable to the levels allowed in drinking water by the Environmental Protection Agency, says lead researcher Tyrone Hayes of the University of California-Berkeley. The study was released Monday in the Proceedings of the National Academy of Sciences. In Hayes' earlier studies, atrazine caused male frogs to begin growing eggs in their testes. In this experiment, 10% of the males exposed to atrazine — one of the most commonly used herbicide in the world — actually changed sex; some were able to breed and lay eggs. Nearly all of the other males had low testosterone and sperm levels, which made them unable to reproduce, Hayes says. The experiment can't tell scientists whether atrazine affects humans in a similar way, Hayes says. But it does raise new questions about the safety of atrazine, which other studies have linked to human birth defects, low birth weight, prematurity and low sperm count. The EPA said in October that it planned to reassess atrazine's safety, including its cancer risk. The European Union has banned the chemical. About 75% of stream water samples and 40% of groundwater samples contain atrazine, according to the U.S. Geological Survey. The Natural Resources Defense Council, an environmental advocacy group, detected atrazine in 90% of tap water samples from 139 water systems. Inexpensive faucet-top water filters can remove the chemical, says Jennifer Sass, a scientist with the group. Several water systems in Illinois, where atrazine is commonly used on corn and other crops, are suing the chemical's manufacturers, asking them to pay the cost of taking the herbicide out of drinking water. The principal scientist for Syngenta Crop Protection, the leading manufacturer of atrazine, says the chemical is safe. Company-sponsored studies that met rigorous EPA standards found atrazine has "no effect on frog sexual development," Tim Pastoor says. He criticized the new study and notes that Hayes tested only one dose of atrazine. A stronger study would have exposed frogs to several doses and noted any trends, he says. Given that atrazine has survived years of scrutiny by the EPA, Pastoor says, he sees no reason to re-examine atrazine's safety now. "As far as we're concerned, it's unnecessary," he says. Although scientists still have many questions about atrazine, Sass says, the chemical should be phased out as a precaution.

Men, especially MASCULINE men, are dangerous to the power structure. Why do you think testosterone (maleness) is such an "evil"? Yet, estrogen (femaleness) is given out like candy?
