Bisphenol-A now linked to male infertility

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.

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 disruptor 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.

Harvard Study: Bisphenol A In Dental Fillings And Sealants

Anthony Gucciardi

After a new study out of Harvard Medical School revealed that dental fillings and sealants contain dangerously high levels of the deadly chemical bisphenol A (BPA), some dentists are now claiming that these fillings and sealants are still perfectly safe for use in children.

These are some of the brands with products containing Bisphenol A.

BPA is an endocrine disruptor that mimics the hormone estrogen. Consequently, has been linked to reduced fertility in men, and even receipts containing BPA can be harmful to male hormone levels when handled. BPA is found in plastics, soft drink cans, soup cans, and thousands of other packaging containers.

A recent California bill would have banned BPA in children-related items such as baby bottles and children’s toys, but was shot down on September 2nd. Connecticut, Maryland, Massachusetts, Minnesota, Vermont, Wisconsin, and Washington already have such laws.

Why then, would it be safe to have fillings and sealants in your mouth that contain this chemical? The research shows that it’s really not. Research shows that BPA levels in saliva skyrocket by around 88 times higher than normal (and what constitutes a “normal” level of a toxic substance?) right after a dental sealing. Experts agree there is no “safe” level of exposure to BPA.

“This chemical is one that you should not be exposed to at any level,” said von Saal, Curators’ professor of biology at the University of Missouri at Columbia.

This is why it is shocking that multiple media outlets have started claiming that BPA is actually not a danger to health, despite routine research proving that this gender-bending chemical is nothing to play around with.

Bisphenol A also Found in Receipt Ink

Researchers have made the startling discovery that a gender bending chemical compound is present on some till receipts.

And the levels of hazardous substance Bisphenol A (BPA) can be high enough to suppress male hormones in the body. The compound, used to make ink visible on thermally sensitive paper, is ingested by men when they handle the receipts and then touch their mouths or handle food.

Prof Frank Sommer, 42, a Berlin-based urologist, explained: ‘A substance like that could shift the balance of the sex hormones in men towards oestrogen.

‘In the long term, this leads to less sexual drive, encourages the belly instead of the muscles to grow and has a bad effect on erection and potency.’

BPA is also used in food cans, shower curtains, toys and babies bottles. In addition to suppressing male hormones it is thought that it may be triggering early puberty in girls – and putting them at greater risk of cancer and diabetes.

Scientists have claimed it is harmful enough for the Government to introduce a precautionary ban.

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 supports its removal and has stated concerns regarding the impact of the chemical on babies and young children.

BPA is known as an endocrine disruptor and interferes with the release of hormones.
