The journal Human Reproduction published a research conducted on 230 Chinese men who were exposed to BPA in their workplace for five years and compared them to 404 others who worked in a factory where no BPA was present.
The results:
The Chinese men working in facilities where they were exposed to BPA had four times the risk of suffering erectile dysfunction and seven times more likely to have difficulties with ejaculation than their counterparts who were not exposed to BPA.
The BPA-exposed men also had dramatically lowered sexual desire and overall less satisfaction with their sex life than men without the chemical exposure.
Many male and female, young and old are being exposed to BPA regularly.
BPA is used in wide range of everyday plastic products including most plastic containers, baby bottles, the lining of cans used for food and beverages, and even dental sealants.
And no one knows for sure what effects the chemical could be having on the human body, including the reproductive system.
A host of animal studies have demonstrated that BPA has a negative impact on the male reproductive system in mice and rats.
Chemical manufacturers and other defenders of BPA have long complained that research raising questions about its health effects was conducted on laboratory animals.
Now we have a human study and this can’t just be dismissed.
Other disturbing implications of the new study indicate that BPA may have other health effect that goes beyond male sexual problems like ED.
In fact, male sexual problems could prove to be early indicators of BPA-related effects on the human body that are more difficult to study, such as cancer or metabolic diseases.
BPA which was developed in the 1930s as a synthetic version of oestrogen, appears to throw off the hormonal balance in the human body, said Dr Li De-Kun, a scientist at the Kaiser Foundation Research Institute which conducted the study with funds from the National Institute for Occupational Safety and Health.
Dr.Li added that 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 human reproductive system.
Question arises from these studies:
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 critical in helping to establish prevention strategies and regulatory policies, said the study's lead author De-Kun Li, MD, Ph.D., in a media statement.
The US Food and Drug Administration, which regulates the chemical industries, have maintained that BPA is safe.
Still, concern over the use of this chemical in common everyday product among consumers has created pressure in the marketplace.
Manufacturers have pledged to take BPA out of baby bottles and water bottles.
What is BPA?
Bisphenol A (BPA) is an industrial chemical used to make polycarbonate plastic resins, epoxy resins, and other plastic products.
It is a chemical building block primarily used to make polycarbonate plastic and epoxy resins.
Polycarbonate plastic is a lightweight, high-performance plastic that possesses a balance of toughness, optical clarity, high level of heat resistance and excellent electrical resistance.
Because of these attributes, polycarbonate is used in a wide variety of common products including digital media (e.g., CDs, DVDs), electrical and electronic equipment, automobiles, sports safety equipment, reusable food , bottles, drink containers and many other products.
BPA is also used in the production of epoxy resins.
Epoxy resins have many uses including engineering applications such as electrical laminates for printed circuit boards, composites, paints and adhesives as well as in a variety of protective coatings.
Cured epoxy resins are inert materials used as protective liners in metal cans to maintain the quality of canned foods and beverages.
Cured epoxy resin have also achieved wide acceptance for use as protective coatings because of its exceptional combination of toughness, adhesion, formability and chemical resistance.
