Weed Killer turns boy frogs into girls

March 2, 2010

Atrazine, a commonly used weed killer in California, turns male frogs into reproducing female frogs, according to a study performed by University of California at Berkeley researchers. [Reuters]

First, atrazine-exposed male frogs develop female features – termed hermaphroditism. Then a small percentage became female frogs through chemical castration.

“Ten percent of the exposed genetic males developed into functional females that copulated with unexposed males and produced viable eggs,” the researchers wrote.

The study included 40 African clawed frogs that were kept in water contaminated with 2.5 ppb (parts per billion) of atrazine. The EPA’s current drinking water standard is 3 ppb.

The European Union banned atrazine in 2004. In the United States, the chemical is the most common pesticide found in ground and surface water, the researchers said.

[…] Weed killer turns boy frogs into reproducing girl frogs…$20 they start testing it on humans soon…sex change anyone? […]

I can think of a few men I would like to volunteer for human experimentation.

Spliting my gut. That’s to cruel.

Hey fellow frog lovers, certain frogs have been known to change sexes in captivity all by themselves in order to reproduce, Jurassic park the frogs DNA remember now, anything to breed and reproduce even breaking the laws of nature. This is just another bad chemical businesses use that will probably filter down and we will all be a little different, possibly, god I would be a homely woman, poor frogs.

Wow you can make a lot of assumptions from this study.

Human studies are needed right away. Any takers? The job pays well but once the transformation is complete, you’ll make 20 percent less than the men do…

So then Atrazine in the domestic water would explain why 90% of American males have hermied over the last 20 years.

… it’s only a small step, then, before atrazine can be employed to recover the endangered Red Legged Frog by changing part of the make population to viable females ….

Racket, I think something is wrong here the frogs want to make it, not this,”changing part of the make population,” just which part is the make population, sorry couldn’t resist good comment though.
