Fluoride added to water makes circus animals calm and prisoners docile. Now we know the reason. A search for “fluoride” and “testosterone” turns up dozens of studies showing adverse effects, such as “Effects of sodium fluoride and sulfur dioxide on sperm motility and serum testosterone in male rats,” “Sodium fluoride disrupts testosterone biosynthesis by affecting the steroidogenic pathway in TM3 Leydig cells” and “Fluoride toxicity in the male reproductive system.”
It’s mostly Chinese researchers who are looking at this problem. A group from Shanxi, China, led by Jiahai Zhang investigated what happened to rats when given sodium fluoride in their drinking water (and also exposed to sulfur dioxide in the air) for eight consecutive weeks. Exposure to fluoride with sulfur dioxide but also to fluoride alone adversely affected testis tissue and serum testosterone levels in rats.
Addition of fluoride—a toxic waste—to drinking water should be banned worldwide, but of course there is resistance, because then the industries producing it (such as the fertilizer industry) would have to engage in the expensive process of cleaning it up.
