What’s on your washcloth? An antimicrobial ingredient in some soap may sap your testosterone levels, say University of California at Davis scientists. They found that when triclocarban enters a man’s bloodstream through his skin, it mimics testosterone, causing his body to ratchet down production of real T in response, say study author Bill Lasley. Ph.D.
Low testosterone has been linked to everything from infertility to depression. Go to hpd.n.m.nih.gov for a full list of soaps and other toiletries that contain triclocarban.
The new study was published online this week by the journal Endocrinology (“Triclocarban enhances testosterone action: A new type of endocrine disruptor?“).
Now, before we get started, that UC Davis report says:
Triclocarban-containing products have been marketed broadly in the United States and Europe for more than 45 years; an estimated 1 million pounds of triclocarban are imported annually for the U.S. market.
- Coast Deodorant Bar Soap-Original Scent
- Mountain Fresh Dial Antibacterial Deodorant Bar Soap
- Safeguard Antibacterial Deodorant Soap
- Zest Deodorant Bar Soap, Whitewater Fresh
- Safeguard Antibacterial Deodorant Bar Soap
- Dial Antibacterial Deodorant Soap
Of course, that last one is the one I’ve been using for about 5 years! Oh, and to make matters worse, all over the house I’ve got Dial Antibacterial Foaming Soap. Guess what the active ingredient is? Yep.
The report also went on to say:
“This finding may eventually lead to an explanation for some rises in some previously described reproductive problems that have been difficult to understand,” said one author, Bill Lasley, a UC Davis expert on reproductive toxicology and professor emeritus of veterinary medicine. More analyses of antibacterials and endocrine effects are planned, he said.
Consumers should not take this study as guidance on whether to use triclocarban-containing products, Lasley said. “Our mothers taught us to wash our hands well before the advent of antimicrobial soaps, and that practice alone prevents the spread of disease.”
Now, they say that the following symptoms can result from low testosterone:
- Low sex drive
- Erectile dysfunction (ED)
- Increased irritability or depression
- Increased body fat
- Loss of body and facial hair
- Reduced muscle mass and strength
- Inability to concentrate
- Decreased bone density; osteoporosis
So, I don’t know about you, but I like my Testosterone. I dumped every freaking Dial product in my house, and I won’t be going back. Now I need to find some all natural soap that is devoid of all these freaking chemicals.
