Bisphenol A - bpa - is a man made chemical that was first synthesized back in 1891. It’s heavily used in the manufacturing processes of polycarbonate plastics and epoxy resins, and it’s often hailed as one of the most conventional chemicals.
Bisphenol A is also the most tested chemical in the world, and through that testing, some rather alarming evidence has been found.
Today’s we’re going to talk about BPA’s effects on the endocrine system, and mainly how it affects male testosterone levels, estrogen levels, and sexu3l function.
Some Science About BPA and the Endocrine System:
This study (577) compared the men who worked at a chemical plant which manufactures BPA to the men who worked at a tap water factory. The results show that the men who worked in contact with BPA had significantly lower serum testosterone levels, and especially free testosterone levels, when compared to the tap water factory fellows.
This study (578) found out that phthalates and BPA from plastics caused delayed puberty, lower free and total testosterone, increased serum estrogen, and increased SHBG count, in boys between the ages of 8-14.
Several animal studies have found that BPA is estrogenic, lowers testosterone, and causes sexu3l dysfunction (579, 580, 581, 582, 583).
This study (584) found out that BPA causes sexu3l dysfunction in human males.
This study (585) saw that Bisphenol A inhibited the enzyme 5-alpha reductase, thus blocked dihydrotestosterone (DHT) production. Same study also found that BPA increased the activity of aromatase enzyme, which converts testosterone into estrogen.
What’s even more troubling is the fact that in all of the studies I’ve seen, 95-99% of the test subjects had detectable levels of BPA in their system. So BPA affects nearly everyone.
That’s why I created this list of 5 hidden sources of BPA, so that you can avoid the things that are slowly crushing the life out of your testicles.
Let’s get to it.
All Kinds of Receipts
Grocery store receipts, bus tickets, air plane tickets, and basically everything that’s “instantly printed” after your purchase, contain huge amounts of Bisphenol A.
This is because the thermal paper on which the receipt is printed on contains alarmingly high levels of BPA as seen in this study. (586)
When you handle those receipts or even worse, store them in your wallet, you’re constantly exposed to BPA. This study (587) actually found out that you can experience a five-fold increase in your BPA levels, few hours after fiddling around with thermal paper.
You can avoid this by not taking the receipts that you don’t actually need, or if you do, don’t fiddle around with them and wash your hands as soon as you can.
NOTE: The ink also contains BPA, the same ink is also used to print newspapers (588).
Toilet Paper
This is a relatively new and one heck of an annoying discovery to me. But the truth is that our toilet paper is laden with BPA.
That’s due to the fact that toilet paper is mostly recycled paper, which contains the BPA laden thermal paper discussed above.
The fact that toilet papers usually contain alarmingly high levels of BPA was first seen in this study. (589)
This is probably one of those things that we have to just live with, because as far as I know there’s no BPA free toilet paper around, mainly because people don’t know that we wipe our behind with the estrogen mimic daily.
Plastics
Plastics are probably one of the biggest reasons behind the fact that our global average on male testosterone levels is so rapidly decreasing.
They’re just filled with estrogen mimics and testosterone lowering chemicals, such as the notorious phthalates and Bisphenol A.
And yes there’s a lot of BPA-free labeled plastics out there. However this excellent report (590) found out that nearly all of the them still contain a chemical called Bisphenol S (BPS) which is basically the same thing but with a different name, and if they don’t, then they’re laden with other estrogen mimics.
Every type of plastic commonly used in food packaging tested positive in some cases, which suggested there was no surefire way to avoid exposure to estrogen mimics.
And that’s the reason why I’ve been as plastic free as I can for the past few years.
Obviously no one can fully avoid plastics, as they’re literally everywhere, but this doesn’t mean that we have to expose ourselves to all of them constantly.
Canned Foods
The epoxy lining in nearly all aluminum cans is made with BPA.
And if the content of the can is something acidic, like tomatoes or soda for example, then you can be sure that the foods are also laden with the chemical.
