Studies conducted on animals have shown consistently that high exposures to fluoride can seriously damage the male reproductive system.
This includes reduced testosterone production, sperm quality, sperm motility and fertility.
Studies conducted in to highly-exposed humans have found similar findings of reduced testosterone and fertility.
Carefully controlled studies have had consistent findings and found direct exposure of fluoride to the testes or semen both inhibits testosterone production & damages sperm.
Check out the findings from these two studies conducted in the 80s looking in to the impact of fluoride on the testes and as a result testosterone production:
1983, Kanwar reported that infusion of testes for four hours with 10 ppm of fluoride inhibited testosterone production.
1985: Chubb reported that infusion of testes for three hours with just 3 ppm fluoride inhibited testosterone production, which “emphasizes the sensitivity of steroidogenesis to fluoride.”
As I’ve mentioned previously; “Fragrance” or “parfum” is potentially the most vaguely listed ingredient in existence.
From a legal perspective, all fragrance is “proprietary” and as a result organisations don’t have to disclose its components.
Sadly, this is where it’s been shown that phthalates are snuck in and when it comes to chemicals that lower testosterone, they are one of the worst culprits!
So pronounced as thal-ates, these are another endocrine-disrupting chemical.
Much the same as many other endocrine disruptors, studies have shown they cause negative effects on the male reproductive system including decreased sperm count, testicular cell destruction and thyroid irregularities.
When it comes to lowering testosterone production, it is the destruction of testicular cells and thyroid irregularities that cause major issues.
This is because the testes & your thyroid are where testosterone & other hormones are produced.
Triclosan is an antibacterial chemical, hence why it’s found in many cleaning products.
It has been linked to concerns over antibiotic resistance & like many chemicals in this article, endocrine disruption and as we know with that, comes lowered testosterone production.
Sodium Lauryl Sulfate
Sodium lauryl sulfate is a chemical you will have seen mentioned in a number of my other overviews of products that contain chemicals that lower testosterone.
It’s used as an ingredient in thousands of products from cleaners, to cosmetics and body cleaning products.
It is sometimes abbreviated to SLS/ SLES or may be listed as sulfates.
With regard to testosterone production and wider health, SLS poses a threat as it breaks down the skins’ moisture barrier.
This allows the dangerous chemicals like the others listed in this article to penetrate the skin far more easily.
SLS is thought to make your skin as much as 100 times more permeable.
Another big cause for concern is that when combined with other chemicals SLS becomes a “nitrosamine”.
This is an extremely strong class of carcinogen and a poison to the body.
There have been multiple studies conducted in to the effects of SLS exposure and they have shown links to organ toxicity, skin & eye irritation, reproductive & developmental toxicity.
Then of course there is the main reason you’re reading this article, it causes endocrine disruption which includes reduced testosterone production.
Final Thoughts & Future Articles
Hopefully this article has painted a picture of the dangers your standard household cleaning products can pose.
The good news is there are alternatives that are both non-toxic and aren;t manufactured with chemicals that lower testosterone production.
I will be publishing an article shortly focused on the alternative products you can use.
To give you an idea for the short term, baking soda, apple cider vinegar and white vinegar are all effective natural cleaners.
The chemicals mentioned in this article and others that potentially lower testosterone are found in other products that you likely use daily.
I’ve written articles covering these, which you can check out below.
