Bisphenol A ( BPA ) and Testosterone
What Is BPA
There is ever increasing concerns that surround the effect that a compound found in everyday life can have on a man’s testosterone production.. The compound in question is Bisphenol A – aka BPA.
What Is BPA
BPA is an industrial chemical that is used in the manufacture of certain plastics and resins found in food packaging since the 1960’s
Most commonly found in polycarbonate type materials such as plastic water bottle and also the lining found inside food cans and bottle tops. BPA has been studied in great depth and these studies have shown that BPA can actually seep into the food or drinks contained within… This has now been linked to possible health effects including issues with the brain, prostate and even behaviour of infants.
The FDA has stated that BPA is ( in its opinion) safe at low levels but research is still ongoing to determine the true long term effects of this compound.
BPA and Testosterone Production
A study recently carried out in China suggests that long term exposure to BPA could lower testosterone levels… the study followed men who worked at a chemical plant that used BPA for a period of 6 months… the study discovered that they had significantly lower free testosterone levels than men who worked at a similar factory without exposure to BPA.
These findings echo earlier reports that BPA can lower mens sex hormone, reducing sperm count and increasing cases of erectile dysfunction
BPA is similar in make up to the female hormone estrogen and this means that could have similar effects to the human body – in particular in men who could see their levels of testosterone reduce as the estrogen increased.
It is generally thought that unless you are exposed to BPA in the workplace, that everyday exposure through the contact with, and use of food containers should not cause too many problems.. but there are some simple guidelines that you could follow to minimise any possible risk from BPA:
- Use PPA free food containers as these should be clearly marked.. another guide is with recycling, if the container had a recycle code of 3 or 7 it is likely to be made with BPA
- Reduced the use of canned foods
- Do not put plastics in the microwave or expose them to any heat sources – as on example – leaving plastic water bottles in the car in the hot sun… the increased heat can cause the plastics to break down allowing the BPA to leach into the water.
- Use alternative containers to both cook and store foods – glass, porcelain and stainless steel containers are preferable.
