A recent study has found that Monsanto’s Roundup pesticide may be responsible for causing infertility. After reviewing the many already well-documented negative impacts Roundup has on the environment and living creatures, it is no surprise to add yet another item to the list.
Researchers tested roundup on mature male rats at a concentration range between 1 and 10,000 parts per million (ppm), and found that within 1 to 48 hours of exposure, testicular cells of the mature rats were either damaged or killed. According to the study, even at a concentration of 1 ppm, the Roundup was able to affect the test subjects by decreasing their testosterone concentrations by as much as 35%.
How can such small levels of exposure have such a profound effect on the reproductive system? Roundup, being a glyphosate-based herbicide is also known to have endocrine disrupting properties.
Much like BPA, glyphosate-based herbicides have the ability to interfere with the natural hormonal balance in the human body, thereby introducing a number of health risks along with even the smallest levels of exposure. These chemicals are strong enough to affect your metabolism, behavior and mood, reproductive organs, and even provoke cancer.
As a result, any plants that are sprayed with roundup carry with them a chemical effect similar to that of other endocrine disruptors, offsetting the hormonal balance and causing adverse effects, despite even the smallest levels of exposure. This in part contributes to the number of males with increased fertility issues in more recent times.

Rates of prostate cancer around the world could be linked to oral contraceptives, a new study suggests.
Dr. Neil Fleshner and Dr. David Margel from Princess Margaret Hospital in Toronto say they have found a significant association between oral contraceptives, prostate cancer and mortality, especially in developed countries in North America and Europe where there is a high use of birth control pills.
The study was published on the online medical journal BMJ Open on Monday.
The authors suggested that estrogen from birth control pills may be excreted through women’s urine, ending up in water supply systems. This, they say, could be boosting rates of prostate cancer.
The authors say the oral contraceptives could be acting as endocrine disturbing compounds (EDCs) — chemicals that interfere with hormones that could result in side effects such as cancer.
“Temporal increases in the incidence of certain cancers (breast, endometrial, thyroid, testis and prostate) in hormonally sensitive tissues in many parts of the industrialized world are often cited as evidence that widespread exposure of the general population to EDCs has had adverse impacts on human health,” said the study.

Teenagers carry 30 percent more of the toxic chemical bisphenol A (BPA) in their bodies than older adults, according to a study conducted by researchers from Statistics Canada.
BPA is an industrial chemical used to make hard, clear plastics for water bottles and baby bottles, and resins to line food and beverage cans. It is also found in the special paper used to print receipts. An endocrine disruptor, it mimics the effect of estrogen in the human body and interferes with the function of other hormones.
“Phthalates and [BPA] … aren’t quite identical to the natural hormone molecules in men’s or women’s bodies, but they come close enough that they occupy the same receptors on estrogen-sensitive tissues and exert their own unique effects on human health,” writes David Steinman in his book Safe Trip to Eden.
BPA has been linked with an increased risk of cancer, reproductive and nervous problems, including changes in the brain.
Researchers collected urine samples from more than 5,400 Canadians between the ages of six and 79, testing for traces of BPA. They found traces of the toxin in 91 percent of those tested.
Teenagers might have higher levels because they consume more food relative to their body weight, the researchers suggested, or because they metabolize it differently. Researchers expressed concern that these higher levels might pose an even more severe risk of developmental problems at an age when the body is undergoing major changes.
The average level of BPA found was just over one part per billion, 1,000 times the level at which estrogen is naturally found in the body.
Health Canada has officially designated BPA as a toxic chemical and ordered its removal from baby bottles, but most other countries have yet to follow suit.
“The No. 1 priority at the moment has got to be getting it out of the lining of tin cans,” said Rick Smith of Environmental Defense. “When nine out of 10 Canadians have a hormonally active chemical in their body, for which easy alternatives are available … why not make some further changes with respect to BPA?”

A product survey conducted by The Independent found that the toxic chemical bisphenol-A (BPA) is used in 18 on the 20 top-selling canned food products in the United Kingdom.
BPA is one of the most widely produced chemicals in the world. It is used to harden plastic in everything from infant and water bottles to mobile phone and computer casings, and also to make linings for cans of food, beverages and infant formula. Yet a growing body of research has implicated the chemical as an endocrine (hormone) disruptor that can lead to cancer, birth defects, behavioral problems and other diseases.
The FDA recently reversed its position on the safety of BPA, acknowledging concern over the chemical’s effects on the development and brains of infants and young children. This move sparked a new, still-ongoing review of the chemical’s safety by the European Food Safety Authority. The British Food Standards Agency still maintains that BPA poses no health risks.
The Independent surveyed manufacturers General Mills, Heinz, Spam, Asda, Baxters, John West, Princes, Premier Foods, Sainsburys and Tesco about the use of BPA in the liners of several of their canned food products. Together, the 20 products represented account for £921 million ($1.4 billion) in sales, or 43 percent of the total for all canned food sold in the United Kingdom.
Every manufacturer sold at least one product lined with BPA. The only cans not lined with the chemical were those containing Tesco canned fruit and Tesco Value tomato products. Yet Tesco and Tesco Value canned fish both came in cans lined with BPA.
Other top-selling products in BPA-lined cans included soups, baked beans, corned beef, canned pies, chopped ham, long spaghetti and Green Giant Niblets.
Claire Dimmer of Breast Cancer UK called for manufacturers to clearly label all cans that are lined with BPA.
“Otherwise it’s impossible for us to make a decision on ways of limiting our and our families’ exposure to this chemical,” she said.

(NaturalNews) The FDA is reevaluating the safety of a popular chemical additive called triclosan, based on recent studies that seem to indicate it causes endocrine disruption in the body and leads to the emergence of drug-resistant “super” bacteria.
Triclosan is commonly found in liquid antibacterial hand soaps and sanitizers, dishwashing detergents, shaving gels, toothpastes, clothing and even children’s toys. It was originally designed as a surgical scrub for people in the medical field, but is now used in pesticides and a variety of different consumer products to ward off pathogens.
It is so common in popular consumer goods that, according to the U.S. Centers for Disease Control and Prevention (CDC), traces of triclosan can be found in the urine of about 75 percent of the population.

(NaturalNews) According to the National Institutes of Health (NIH), almost 11 percent of Americans age 20 or older have diabetes. And the most common form of this disease, type 2 diabetes, has reached epidemic proportions. Now scientists have found a link between vitamin D deficiency and the inability of many patients with this kind of diabetes to keep their blood sugar under control. What’s more, this raises the strong possibility that, along with being overweight and sedentary, a lack of vitamin D could be a major factor in triggering type 2 diabetes in the first place.
Esther Krug, MD, an assistant professor of medicine at the Johns Hopkins University School of Medicine and an endocrinologist at Sinai Hospital in Baltimore, Maryland, just presented this research in San Diego at the Endocrine Society’s 92nd Annual Meeting. “This finding supports an active role of vitamin D in the development of Type 2 diabetes,” Dr. Krug said in a statement to the media.

(NaturalNews) Following its 2008 declaration that the chemical bisphenol-A (BPA) is a safe additive in food and beverage plastics, the U.S. Food and Drug Administration (FDA) received criticism from consumer advocacy groups and others for neglecting scientific evidence that indicated the contrary. The agency reluctantly agreed to review its position and recently reversed its position, declaring that it now has concerns about the safety of BPA.
Several scientific studies have verified that BPA is a highly toxic endocrine disruptor that can impede proper reproductive function and lead to cardiovascular disease, liver problems, and diabetes. It is especially harmful during the early developmental stages because it hinders the proper development of organ tissues and glands and inhibits proper sexual maturity.
A 2009 Harvard University study found that people who drank from polycarbonate bottles containing BPA for just one week experienced a two-thirds increase of BPA in their urine. Published in the journal Environmental Health Perspectives, the study verified that the BPA used in containers leaches very easily into food and beverages, especially when heated.

A small study suggests people may be routinely exposed to the chemical bisphenol A through everyday consumption of canned goods.
The study has food safety and consumer advocates calling for a crackdown on the chemical in a food safety bill expected to reach Senate debate in the coming weeks.
Bisphenol A, also known in BPA, is widely used in plastics and as a lining for cans holding everything from soup to fruit to sardines. It has come under intense scrutiny in recent years because in addition to preserving food, it also mimics human hormones and has been classified as an endocrine disruptor.
Five states and several municipalities have restricted the use of BPA in baby products and infant formula cans because of concerns that exposure may be dangerous for young children. Tuesday’s study, though small, suggests the chemical may be widely consumed by children and adults in everyday groceries.
A study conducted by a coalition of consumer and food safety groups found detectable levels of BPA in 46 of 50 grocery store cans tested. The results suggest BPA routinely leaches from can linings into food.
BPA has been associated with a variety of health problems in laboratory animals, including cancers, early puberty, and developmental problems.
The highest BPA level detected was 1,140 parts per billion, found in a can of Del Monte French Style Green Beans obtained from the pantry of a study participant in Wisconsin.

The government of Denmark has released a 326-page report affirming that endocrine disrupting chemicals are probably continuing to the birth of fewer males and the “feminization” of existing ones.
The report centers on chemicals like PVC, flame retardants, phthalates, dioxins, PCBs and bisphenol-A, all of which mimic the action of estrogen in the body. The researchers concluded that due to the prevalence of these chemicals, children could easily be exposed to high enough levels to place them at “critical risk” of harm.
The chemicals have been blamed for falling sperm counts among men worldwide, and their full effects remain unknown. A study by researchers at Erasmus University in Rotterdam, Netherlands, found that male children who had been exposed to PCBs and dioxins while in the womb were more likely to dress up in female clothes and play with dolls than boys who had not been. Other research has documented a connection between prenatal phthalate exposure and “feminization” of male genitals, including smaller penises.
Evidence is increasingly emerging that estrogen mimics might also be responsible for a puzzling phenomenon: fewer boys are being born than ever before. Typically, 106 male children are born for every 100 females in most populations. In recent years, however, this distribution has been shifting in favor of females, with endocrine disruptors a likely culprit.
For example, a Canadian Inuit community living on Lake Huron and surrounded by chemical factories produces two girls for every boy born. Similar phenomena have been observed in contaminated communities in Brazil, Israel, Italy, Taiwan and the Arctic Circle, as well as among workers in Russian pesticide factories.
Many hormone-mimicking chemicals build up in the body and resist environmental degradation, meaning that they are now widely distributed across the planet.
“There is very little, if anything, individuals can do to prevent contamination of themselves and their families,” the environmental group WWF said.

Contamination of drinking water by a common herbicide poses a greater health threat than previously believed, according to a report issued by the nonprofit environmental organization Natural Resources Defense Council (NRDC).
The Environmental Protection Agency (EPA) monitors average yearly levels of the popular herbicide atrazine in drinking water supplies, based on four tests per year. But the NRDC notes that levels of the toxin in drinking water regularly spike after heavy rains or during the spring when it is being widely applied, and that the four yearly testings may miss these events. The organization’s researchers found several such spikes in its own testing of water supplies in towns in agricultural regions of the South and Midwest.
“Our biggest concern is early-life-stage development,” said Jennifer Sass of the NRDC. “If there’s a disruption during that time, it becomes hard-wired into the system. These endocrine disrupters act in the body at extremely low levels. These spikes matter.”
Because atrazine is compatible with no-till farming, it is popular among farmers seeking to acquire a “green” label by reducing their carbon footprint. It is known to disrupt the hormonal system, and may cause cancers and menstrual problems in adults. It is considered especially dangerous to the developing reproductive systems of fetuses and children. The chemical has been shown to kill aquatic microorganisms and suppress the immune systems of larger animals, and it can cause limb or reproductive deformities in amphibians at levels as low as 0.1 parts per billion.
The EPA has set a threshold of 3 billion parts per billion for permissible atrazine levels, which the NRDC says would be too high even without periodic spikes. The NRDC analysis of 139 different municipal water systems found that 54 of them had a one-time spike higher than 3 parts per billion at some point in 2003 or 2004.
Home or municipal carbon filters can remove atrazine from water, but many municipal treatment plants do not use such procedures.
