The study which was published this month in the journal Human Reproduction, included 230 Chinese men who were occupationally exposed to BPA and 404 unexposed workers who reported on sexual function via in-person interviews. After controlling for variables that might influence results (like time on the job and age), it was discovered that exposed workers were about four times more likely to report a decreased sexual desire and/or reduced satisfaction with their sex life, were four and a half times more likely to report experiencing erectile dysfunction, and were more than seven times as likely to report having ejaculation difficulty.

BPA is a man-made organic compound that is a white to light brown flaky powder. BPA is used primarily in the production of polycarbonate plastics and epoxy resins that are then used in food and drink packaging and to coat metal products including the inside of food cans, bottle tops, and as coatings inside water supply lines. BPA is also used in some recycling applications and in some dental sealants.

 

BPA is an endocrine disruptor and as such, even at low doses, research suggests it may be able to mimic the body’s own hormones. Animal studies have consistently shown that BPA exposure increases the risk of poor pregnancy outcomes and can permanently impair the ability to reproduce. Many states have moved to restrict the use of BPA in baby bottles and some other food containers. Such exposure is likely responsible for most BPA exposure in humans although exposure via use of canned food may also be problematic. Recent testing by Consumer Reports found BPA levels higher than expected in commonly used canned foods.

 

Consumers can avoid BPA exposure by limiting their use of canned goods including canned soft drinks and by consuming beverages from glassware and stainless steel bottles and by using glass or metal containers for food storage and ceramic or glass containers for microwave heating. Avoiding certain plastic wraps during storage and heating can also reduce BPA exposure levels.

Stainless Steel Water Bottles

"Having some of these around will prevent you from buying the small plastic water bottles. You will avoid the BPA exposure and do the planet a favor. Prices range from about $10 to $40. Amazon.com has pretty good prices but you can pick them up just about anywhere."

 

Non-Plastic Food Containers

"Having glass storage containers around is your insurance policy against heating things up in plastics which can leach BPA.  Again, Amazon.com has pretty good darn prices on these but you can pick up sets at Target, Walmart etc... ."
