Estrogen in suburban ponds is turning male frogs female

"Our work shows that, for a frog, the suburbs are very similar to farms and sewage treatment plants," researcher Max Lambert said.

NEW HAVEN, Conn., Sept. 8 (UPI) -- Male frogs seeking a mate might have better luck in suburban ponds -- that's if they don't mind the risk of turning into females themselves.

Researchers at Yale University found suburban ponds, near shrubs, backyard gardens and manicured lawns, feature higher ratios of female green frogs than do ponds surrounded by forest. The new study, published in the journal Proceedings of the National Academy of Sciences, suggests higher levels of estrogen in suburban water are turning male green frogs female by disrupting the animal's endocrine system.

"In suburban ponds, the proportion of females born was almost twice that of frog populations in forested ponds," lead study author Max Lambert, a doctoral student at the Yale School of Forestry & Environmental Studies, explained in a press release. "The fact that we saw such clear evidence was astonishing."

Researchers didn't aim to locate the sources of estrogen in the water, but some of the ponds surveyed were connected to septic systems and sewer lines. Previous research has shown agricultural runoff and wastewater contamination near farms and water treatment plants are having similar effects on hormone regulation in frogs.

But the estrogen that's feminizing frogs in suburban ponds isn't necessarily coming exclusively from wastewater and pesticides. Plant species common to suburbs, like clover, naturally produce phytoestrogens.

"Our work shows that, for a frog, the suburbs are very similar to farms and sewage treatment plants," Lambert said. "Our study didn't look at the possible causes of this, partly because the potential relationship between lawns or ornamental plantings and endocrine disruption was unexpected."

Estrogen contamination could also have an impact on other frog species, as well as salamanders, birds and mammals found in suburban environs. As such, Lambert and his colleagues say their research is ongoing.

"Some of our lab's current work is trying to understand how the suburbs influence sexual development in other species," he said.

Where do you think all those psychoactive meds are winding up, too?

Are those aphrodisiacs intended for heterosexual activity, gay or both? Are those substances producing metrosexuals in the East?

Some claim a lot of plastics in food packaging contains these hormones. In other words, we are bombarded by Estrogen, no matter what?

Why I only drink distilled water...They only find what they test for, if that.

Distilled water is unstable and will actively leach minerals from your body.

Might wanna add a good mineral supplement to your life.

It appears this contamination may have a variety of sources. The article mentions pesticides, and adds, Plant species common to suburbs, like clover, naturally produce phytoestrogens.

Perhaps the researchers will follow up on this.

I use Doulton and Aquacera ceramic/charcoa filters. I hope they do the job.

Soy is a known phytoestrogen. Try and buy any product from the grocery store that does not have soy listed in the ingredients. Good luck.

I personally believe part of the reason for the spectacle of the Democrat Party debate is related to soybean poisoning. Though most of it is probably straight up psychosis.

Estrogen is known to seep into the ground wherever Connecticut republican politicians gather. It is an environmental crisis....

This contamination is from synthetic birth control hormones excreted in women’s urine. If it was any other substance, the EPA would be suing the manufacturers out of business. However, since birth control is a key component of the left’s agenda, there will be no action taken. Hypocrites.

Estrogen in foods such as Ede mama, soy, tofu, Sushi, tuna can linings

Wait'... tuna can linings ?

The other stuff I know about...

Estrogen would cause low labido, mood swings and bone loss in men. It makes men more feminine but I don’t think it reverses their sexual preference. Nutritional deficiencies in the womb, on the other hand causes homosexuality. It is a congenital defect causes by mostly by mineral deficiencies. Our farmlands have been stripped of minerals, particularly trace minerals. This has been known since the early seventies. The small portion of humanity that lives on high altitude, glacially ablated farmland has almost no incidence of homosexual or intersexual defects or any other birth defect. If pregnant women want straight children they should take a full spectrum of trace and major minerals that have been chelated for greater absorption. Typical prenatal are inadequate at preventing many birth defects.

suburban ponds

This article really has it out for the suburbs but ponds are actually a feature of exburbs. A big source of phytoestrogens would be farms growing soy beans, a plant that's developed chemical warfare defenses against being eaten.

Compared to the suburbs the growth stunting pollution and feminization chemicals in big cities is off the charts. If the toxins didn't kill a green frog hopping down Broadway it would be gay before it reached Macy's.

So why can’t we seed the clouds over Eastern Syria with it? :)
