Chinese factory workers exposed to high levels of the plastics chemical BPA had low sperm counts, according to the first human study to tie it to poor semen quality.
The results "are at least suggestive of the possibility that BPA may be one of the compounds that are causing some of these changes" in sperm, she said. But Gore said stronger evidence is needed to prove that BPA is indeed the culprit.
Low sperm counts were found in workers who had detectable levels of bisphenol-A in their urine. Poor sperm quality was two to four times more prevalent among these men than among workers whose urine showed no sign of BPA. The lowest sperm counts were in men with the highest levels of BPA.
The U.S. Food and Drug Administration has been evaluating the chemical's safety but declined to say if it is considering following Canada's lead in declaring the chemical toxic.

Population control conspiracy theorists may be onto something here....
So now a study exists to back up what many people have been saying for quite awhile... That BPA is a toxin that effects fertility.
Is this an attack on manhood - leading to global feminization?

Health authorities have always believed these trace exposures were harmless. But the question of whether eating canned food entails any health risks because of BPA, a compound that mimics the female hormone estrogen, is about to receive one of its most thorough reviews.
The WHO meeting is being held in Canada, in part because it is the leading jurisdiction in the world on BPA regulation. The federal government was the first in the world to add the man-made chemical to a national toxic substances list last month, after having earlier banned baby bottles made from the compound, another international first.
There is also growing evidence that BPA has impacts in the wider population. A study published last week in the journal Fertility and Sterility of workers in Chinese factories who used BPA linked the chemical to poor sperm quality among those with the highest exposures. Earlier this year, another study, of typical Americans, found those with the most BPA had a 45 per cent higher risk of developing cardiovascular disease.

Has a safe level actually been established?
Yes. The internationally established safe level known as the Tolerable Daily Intake (TDI) for BPA is 0.05 mg per kilogram of body weight per day. The TDI is an estimate of the amount of a substance in food that can be ingested daily over a lifetime without appreciable health risk. The TDI is based on animal studies and incorporates a safety factor which allows calculation of a safe level of consumption for humans to be undertaken.
Are very low levels of BPA in food of a concern?
FSANZ has evaluated the safety of BPA in food, including that consumed by infants from baby bottles and concluded that levels of intake of BPA are very low and do not pose a risk to public health for any age group. For example, to reach the safe level (TDI) for BPA:
•a 5 kg baby would need to consume more than 80 large (240 mL) polycarbonate plastic baby bottles full of infant formula a day, around fifteen to twenty times more than a baby would eat.
•a 9 month old baby weighing 9 kg would have to eat more than 1 kg of canned baby custard containing BPA every day, assuming that the custard contained the highest level of BPA found.

A Health Canada study of canned pop has found the vast majority of the drinks contain the chemical bisphenol A, a substance that imitates the female hormone estrogen and is banned in baby bottles.
Out of 72 drinks tested, 69 were found to contain BPA at levels below what Health Canada says is the safe upper limit. However, studies in peer-reviewed science journals have indicated that even at very low doses, BPA can increase breast and ovarian cancer cell growth and the growth of some prostate cancer cells in animals.
The federal department's study was published in January in the Journal of Agricultural and Food Chemistry and was posted on Health Canada's website. When asked why the study was not widely publicized, Shank said "it wasn't our intent" to hide it.
Low levels of BPA were detected in all surveyed canned beer samples with levels ranging from 0.081 to 0.54 µg/L*, and only one bottled beer sample at a level of 0.054 µg/L*. The presence of BPA in canned beer samples and its absence (or lower level than canned) in bottled beer samples suggests that migration from can coatings is a source of BPA in canned beer products.
But things have changed. Last month, reacting to a cascade of research studies linking BPA to serious health conditions, senior FDA leaders appointed by President Obama issued a strong warning to the public to avoid the chemical. FDA officials announced a series of investigations of BPA safety, meanwhile committing the agency, on its own and in conjunction with Canadian counterparts, to “support” food processing industry efforts to find a suitable replacement for BPA in can linings, particularly for canned infant formula.
Right now, the Japanese canning industry voluntarily uses non-BPA can linings, but nearly all other major canners in industrialized nations use epoxy resin with BPA. Scientists and policy-makers worldwide are stepping up research into BPA and into alternatives for cans. Later this year, the World Health Organization and the Food and Agriculture Organization of the United Nations are planning to convene an international “Expert Consultation on BPA.”
Well then – what’s in the cans? Pepsi is silent on that question. At least Coca-Cola’s website acknowledges the BPA controversy and takes a position. Pepsi’s position is ostrich. On Feb. 3, we emailed and telephoned Pepsi customer service and media relations to ask if Pepsi had managed to come with a non-BPA can lining.
So far – nothing. Pepsi hasn’t returned our calls. We can only assume this means Pepsi, like Coke and most other canners outside Japan, uses BPA-based epoxy resin.

seriously, you guys ought to do a little research into what the stuff does to alligators......
Increasing research shows damage from endocrine disruptors. Their use in products will be increasingly called into question. Companies using these products are poor investment risks and could have some liability risks in the future as well. They have had a pass because the companies using these substances were the ones funding the research. While that is still largely the case, independent researchers, both here and offshore, are replicating pretty dramatic experiments.
The most interesting one I know of offhand is that concerning alligators in Lake Apopka in Florida. Birth defects were observed in male alligators, and these defects were replicated in succeeding generations when unaffected alligators were exposed to the contaminated water in the lake. This wasn’t specifically Bis A, but the story is cautionary because endocrine disruptors behave similarly and are active at low concentrations and where other contaminants are present as well.
There are many instances of bad science from the alphabet agencies because of undue influence. The pharmaceutical industry is another example where independent scientists are beginning to catch them, sometimes with the industry’s own research, in regression analyses, and in other ways. Joseph Biederman, of Harvard, among others, have been outed this year. University research funded by industries which stood to profit are increasingly getting busted for conflicts of interest and other misbehaviors.
