Bisphenol exposure thought to increase chances of impotence

Fresh studies into Bisphenol exposure have found that factory workers, who operate in working environments where this chemical is present, run the risk of suffering with erectile dysfunction and are 7 times more likely to experience the symptoms that are associated with premature ejaculation. The compounds have been seen to be hazardous to human health since the early 1930s.

According to experts, workers who are exposed to it are 4 times more likely to suffer an inability to obtain an erection and 7 times more likely to experience some degree of premature ejaculation. The study was the first of its kind, although previous research involving animals have proven that BPA has a negative effect on the reproductive system in rodents.

The study ran for 5 years, and was published in the Human Production Journal. It looked at 634 Chinese factory workers, to draw a comparison between those who had been exposed to BPA and those who had worked away from it. BPA is used in polycarbonated plastics, commonly found in baby bottles, plastic containers and the lining of cans, commonly used for food and drink.

Not only is BPA thought to be a powerful human endocrine disrupter, but the first epidemiological study of its effects on the male reproductive system served to provide important information. Researchers had estimated that the BPA levels that factory workers in China were exposed to, were 50 times higher.

The author of the study, Di-Kun-Li, commented :"Because the BPA levels in this study were very high, more research needs to be done to see how low a level of BPA exposure may have effects on our reproductive system," said the study's lead author De-Kun Li, from Kaiser Permanente's Division of Research. "This study raises the question: Is there a safe level for BPA exposure, and what is that level? More studies like this, which examine the effect of BPA on humans, are critically needed."

Erectile dysfunction affects 40% of men. Anybody suffering with symptoms are advised to seek the help of a trained health practitioner who may describe key treatments such as Viagra sildenafil citrate, Cialis tadalafil and Levitra vardenafil.
