#12 Bisphenol-A Is Linked To Infertility
A very common chemical known as bisphenol-A is found in thousands upon thousands of our plastic products. It also turns out that it has some really nasty effects on the human body. Fortunately, some in the mainstream media are beginning to acknowledge this. Back in October, one of the largest UK newspapers published an article entitled "Bisphenol-A now linked to male infertility" which made the following unequivocal statement about the dangers of BPA.... Bisphenol-A (BPA), known as the "gender bending" chemical because of its connection to male impotence, has now been shown to decrease sperm mobility and quality.

A controversial chemical used for decades in the mass production of
food containers and baby bottles has been linked to male infertility for the
first time.

Bisphenol-A (BPA), known as the "gender bending" chemical because of its connection to male impotence, has now been shown to decrease sperm mobility and quality. The findings are likely to increase pressure on governments around the world to follow Canada and ban the substance from our shelves. BPA is used widely to make plastic harder and watertight tin cans. It is found in most food and drink cans – including tins of infant formula milk – plastic food containers, and the casings of mobile phones, and other electronic goods. It is also used in baby bottles though this is slowly being phased out. BPA has been the subject of intense research as it is a known endocrine disrupter which in large quantities interferes with the release of hormones. Earlier studies have linked it to low sex drive, impotence and DNA damage in sperm. Now a new five year study claims to have found a link between levels of BPA in the blood and male fertility. For their study of 514 workers in factories in China, researchers at Kaiser Permanente, a California-based research centre, found that men with higher urine BPA levels were two to four times more at risk of having poor semen quality, including low sperm concentration, low sperm vitality and mobility. What is more the amount of the BPA in the blood seemed to be inversely proportional to sperm quality. Even those with less than the national average BPA levels in America were effected, it was claimed."Compared with men without detectable urine BPA, those with detectable urine BPA had more than three times the risk of lowered sperm concentration and lower sperm vitality, more than four times the risk of a lower sperm count, and more than twice the risk of lower sperm motility," said study lead author Dr De-Kun Li.He claims the research, published in the journal Fertility and Sterility, was the first human study to report an adverse association between BPA and semen quality. Previous studies found a negative link between BPA and male reproduction in mice and rats It was also the third study in a series by Dr Li and his colleagues examining BPA's effect on humans. The first study, published in November 2009, found that exposure to high levels of BPA in the workplace increases men's risk of reduced sexual function. Increasing BPA levels urine are also associated with worsening male sexual function, according to the second study, published in May 2010. The latest study, funded by the US National Institute of Occupational Safety and Health, throws further doubt on the safety of BPA."The finding of the adverse BPA effect on semen quality illustrates two points: first, exposure to BPA now has been linked to changes in semen quality, an objective physiological measure," Dr Li said."Second, this association shows BPA potential potency: it could lead to pathological changes of the male reproductive system in addition to the changes of sexual function.“When you see this kind of association with semen you have to wonder what else BPA has an effect on,” said Dr Li.As a precautionary principle, he said, “Everybody should avoid BPA as much as you can.”The researchers noted that BPA may also affect female reproductive systems and have adverse effects on ailments such as cancer or metabolic diseases. BPA has already been banned in Canada and three US states.
Bottles and cans containing the chemical have been linked to breast cancer, heart disease, obesity, hyperactivity and other disorders. Most manufacturers of baby bottles have stopped putting it in their products but older stock containing the chemical is still on sale. The US Food and Drug Administration (FDA) supports its removal and has stated concerns regarding the impact of the chemical on babies and young children.It can affect disorders associated with metabolism, fertility and neural development.
Reproductive system and sexual behavior research HERE
A study released in 2013 demonstrated that BPA in weak concentrations is sufficient to produce a negative reaction on the human testicle. The researchers found that a concentration equal to 2 micrograms per litre of bisphenol A in the culture medium, a concentration equal to the average concentration generally found in the blood, urine and amniotic fluid of the population, was sufficient to produce the effects. The researchers believe that exposure of pregnant women to bisphenol A may be one of the causes of congenital masculinisation defects of the hypospadia and cryptorchidism types the frequency of which has doubled overall in the past 40 years. They also suggested that "it is also possible that bisphenol A contributes to a reduction in the production of sperm and the increase in the incidence of testicular cancer in adults that have been observed in recent decades." A 2007 study using pregnant mice showed that BPA changes the expression of key developmental genes that form the uterus, which may impact female reproductive tract development and future fertility of female fetuses. A series of studies made in 2009 found: Mouse ovary anomalies from exposure as low as 1 µg/kg, concluded that BPA exposure causes long-term adverse reproductive and carcinogenic effects if exposure occurs during prenatal critical periods of differentiation. Neonatal exposure of as low as 50 µg/kg disrupts ovarian development in mice. Neonatal BPA exposition of as low as 50 µg/kg permanently alters the hypothalamic estrogen-dependent mechanisms that govern sexual behavior in the adult female rat. Prenatal exposure to BPA at levels of (10 μg/kg/day) affects behavioral sexual differentiation in male monkeys. In placental JEG3 cells in vitro BPA may reduce estrogen synthesis. BPA exposure disrupted the blood-testis barrier when administered to immature, but not to adult, rats. Exposure to BPA in the workplace was associated with self-reported adult male sexual dysfunction.A 2009 rodent study, funded by EPA and conducted by some of its scientists, concluded that, compared with ethinyl estradiol, low-dose exposures of bisphenol A (BPA) showed no effects on several reproductive functions and behavioral activities measured in female rats. That study was criticized as flawed for using polycarbonate cages in the experiment (since polycarbonate contains BPA) and the claimed resistance of the rats to estradiol, but that claim was contested by the authors and others. Another 2009 rodent study found that BPA exposure during pregnancy has a lasting effect on one of the genes that are responsible for uterine development and subsequent fertility in both mice and humans (HOXA10). The authors concluded, "We don't know what a safe level of BPA is, so pregnant women should avoid BPA exposure." In a 2010 study, mice were given BPA at doses thought to be equivalent to levels currently being experienced by humans. The research showed that BPA exposure affects the earliest stages of egg production in the ovaries of the developing mouse fetuses, thus suggesting that the next generation may suffer genetic defects in such biological processes as mitosis and DNA replication. In addition, the research team noted that their study "revealed a striking down-regulation of mitotic/cell cycle genes, raising the possibility that BPA exposure immediately before meiotic entry might act to shorten the reproductive lifespan of the female" by reducing the total pool of fetal oocytes. Another 2010 study with mice concluded that BPA exposure in utero leads to permanent DNA alterations in sensitivity to estrogen. Also in 2010, a rodent study found that by exposing fetal mice to BPA during pregnancy and examining gene expression and DNA in the uteruses of female fetuses, BPA exposure permanently affected the uterus by decreasing regulation of gene expression. The changes caused the mice to over-respond to estrogen throughout adulthood, long after the BPA exposure, thus suggesting that early exposure to BPA genetically "programmed" the uterus to be hyper-responsive to estrogen. Extreme estrogen sensitivity can lead to fertility problems, advanced puberty, altered mammary development and reproductive function, as well as a variety of hormone-related cancers. One of the authors concluded that BPA may be similar to diethylstilbestrol that caused birth defects and cancers in young women whose mothers were given the drug during pregnancy. A 2011 study using the rhesus monkey – a species that is very similar to humans in regard to pregnancy and fetal development – found that prenatal exposure to BPA causes changes in female primates' uterus development. A 2011 rodent study found that male rats exposed to BPA had lower sperm counts and testosterone levels than those of unexposed males.A 2011 mice study found that male mice exposed to BPA became demasculinized and behaved more like females in their spatial navigational abilities. They were also less desirable to female mice

We truthers have known for YEARS that BPA in plastics release oestrogen-mimicking chemicals, especially when in those lovely microwave meal containers that people all eat out of and THEN you wonder why male fertility has dropped 50% in 40 years? The problem with scientists is that they're so compartmentalised into their various specialities and cannot see how one thing (BPA to make plastics hard) can affect another thing (BPA releasing oestrogen-mimicking chemicals when heated up) But what is really suspect is how there were many other chemicals available to make hard plastics harden and yet they had to go with the one that causes male fertility problems. Part of the population reduction agenda, hmmm? Just like the tetanus vaccines given to brown people in Africa and Australasia that also contain the hCG hormone which then causes pregnant women who have the tetanus shot to immediately abort their babies...

Slow Kill Holocaust: Proof the Government is Killing You
Watch : HERE
Proof that the government is poisoning the population. With their stated goal to reduce population worldwide, the eugenicists who run the world state have resorted to any means to target reproduction and fertility, including the outrageous measures identified in the 1969 Planned Parenthood -- World Population memo written by Frederick S. Jaffe. That memo proposes reducing U.S. fertility via postponement of marriage, discouraging tax incentives for parents, encouraged increases in homosexuality, adding fertility control agents to the water supply and encouraging women to work, as well as measures including forced abortion and payments to encourage abortions. Many of these draconian calls for involuntary fertility control reflect some of the most controversial entries in the 1977 Ecoscience volume written by current White House science advisor John P. Holdren & population bomb scare-monger Paul Ehrlich. From Bisphenol-a (BPA), to GMO crops, fluoride in water and countless other toxins slow killing modern society, the elite controllers have intentionally triggered cancer, disease and sterility while trying to mask their attack through "slow" ambient poisons that gradually drag down the masses as they eat factory-produced foods, drink public water and are bombarded by packaging products of all kinds. BPA and other synthetic estrogen-mimickers are particularly harmful, and widely used in food-grade plastics, metal food cans, recycled paper & receipts, as well as countless other products-- as they interfere with the endocrine system, create gender-bending effects, reportedly cause male infertility, trigger early puberty, contribute to hyper-aging and are linked to breast cancer in adults, prostate cancer in children and numerous other harmful effects. We participate in our own destruction through the designs of the elite via our own ignorance. Learn the truth, and the truth shall set you free. Read more on how to eliminate and reverse the effects of Bisphenol-A (BPA) and other toxins naturally.

7 Nasty Effects of BPA – The Plastic Chemical
Bisphenol a (BPA) is the widely used chemical found in many plastics, food can linings, and even on US dollars and receipts. Known as an endocrine-disrupting chemical that mimics the hormone estrogen, BPA has been linked to numerous negative health effects in countless studies. The worst part? While the Food and Drug Administration considered banning the chemical in March of 2012, the ban was denied, and BPA continues to be ubiquitous. So what exactly does mean? It means the entire U.S. is still subjected to the chemical’s negative effects.
Here are 7 nasty effects of BPA.
1. Breast CancerBreast cancer is slowly becoming one of the many well-known negative outcomes induced by BPA exposure. In fact, over 130 studies have confirmed the link between bisphenol A and to ailments like breast cancer, obesity, and reproductive problems. Ironically, the popular nonprofit Susan G. Komen for the Curepartners with many bottled water companies for their ‘For the Cure’ races across the nation. The problem, obviously, is that most of these plastic bottles contain BPA.
2. Early PubertyWhile girls typically enter into puberty (or have in the past, at least) at just over ten years of age, studies show that this age has fallen by more than a year within only one generation. Some girls are even seeing breasts at 7 years old. Although there are other factors to consider, BPA may be to blame as well. After examining 1,151 girls between the ages of 6 and 8 in the United States over a two year period, researchers found that multiple chemical classes were detected at high levels within the girls’ urine. About one-third of the girls went through puberty prematurely.“Our research shows a connection between chemicals that girls are exposed to on a daily basis and either delayed or early development. While more research is needed, these data are an important first step in evaluating the impact of these common environmental agents in putting girls at risk,” lead researchers Dr Mary Wolff said.3. Heart DiseaseSome research has linked both BPA and phthalates to a disorder known as atherosclerosis. This disorder, which is the hardening of the arteries through the buildup of plaques, negatively impacts blood flow and ultimately increases your risk of heart disease. Shocking, the research is not the first of its kind. One team also found that individuals with higher levels of bisphenol-a in their urine were more than twice as likely to suffer from coronary heart disease than those with lower levels.
4. and 5. Infertility in Males and FemalesBisphenol a has been found to be adversely affecting male genital development, subsequently leading to compromised fertility health. One study examined the effects of BPA on the distance between the genitalia and the anus in males, known as the Anogenital distance (AGD). AGD is very important biologically for a number of reasons, and plays a prominent role in the health of one’s fertility. Researchers found that parental exposure to BPA during pregnancy was associated with shortened AGD in male offspring. In other words, high level BPA exposure led to offspring with AGD defects. AGD has been linked to fertility in males, making BPA’s negative impact on the male reproductive systemnoteworthy. Men with an AGD lower than the median, which sits around 52 mm (2 in), have seven times the chance of being sub-fertile as compared to those with a longer AGD. But males aren’t the only one’s suffering; BPA has been linked to reproductive issues in women as well. In one study, researchers found that BPA caused reproductive problems that can affect women, including abnormal egg development. The eggs of fetuses exposed to BPA had difficulty forming follicles, which ultimately increases the risk of eggs dying before maturation. Additionally, the researchers observed other abnormalities, showing signs that they would carry too many chromosomes as a result of not dividing during development. This could lead to miscarriages or disorders like Down Syndrome.
6. Sparks Multiple Negative Brain AlterationsFurther adding on to BPAs long list of negative effects, some research has also found that the chemical disrupts a gene responsible for proper nerve cell function, ultimately leading to compromised brain development. Researchers of the study, published in the journal Proceedings of the National Academy of Sciences, discovered that BPA could damage central nervous system development by disrupting a gene called Kcc2.“Our study found that BPA may impair the development of the central nervous system, and raises the question as to whether exposure could predispose animals and humans to neurodevelopmental disorders,” study researcher Dr. Wolfgang Liedtke, M.D., Ph.D., said. Another study found that exposure to bisphenol-A early in life can spark changes in gene expression. The changes occur in a part of the brain called the amygdala, which can lead to increased levels of anxiety.The study abstract states:“Early life exposure to Bisphenol A (BPA), a component of polycarbonate plastics and epoxy resins, alters sociosexual behavior in numerous species including humans. The present study focused on the ontogeny of these behavioral effects beginning in adolescence and assessed the underlying molecular changes in the amygdala.”
7. ObesityLast, but certainly not least, BPA may be one of many factors responsible for the obesity epidemic. One study found that high BPA exposure is associated with obesity in the general adult population in the U.S.Another study, examining BPA concentrations in the urine of kids aged 6 to 19, found that obese children made up 22% of individuals with the highest BPA levels in their urine. About 10% of kids who had the lowest BPA concentration in their urine were obese. HERE
"Chemical BPA Linked to Heart Disease, Study Confirms"
'BPA is commonly used in consumer plastics, particularly polycarbonate plastic items such as manysunglasses, reusable bottles, food packaging, and baby bottles. It also lines the inside of food cans.In a sampling of U.S. adults, those with the highest levels of BPA in their urine were more than twice as likely to suffer from coronary heart disease than those with the lowest concentrations of BPA.The findings almost perfectly dovetail with a 2008 study on the same topic, said study co-author Tamara Galloway, an ecotoxicologist at the U.K.'s University of Exeter.'.... click the link above to continue.
