There have been more than 60 scientific studies on animals that have identified an association between male infertility and fluoride exposure. All of those have tested the effects of pharmaceutical grade fluoride, but we are not that lucky. We get waste products from the fertilizer industry that are actually classified as hazardous wastes. Mmmm. Drink up!
Comparison of the toxicity of fluoridation compounds in the nematode Caenorhabditis elegans.
Fluorides are commonly added to drinking water in the United States to decrease the incidence of dental caries. Silicofluorides, such as sodium hexafluorosilicate (Na2 SiF6 ) and fluorosilicic acid (H2 SiF6 ), are mainly used for fluoridation, although fluoride salts such as sodium fluoride (NaF) are also used. Interestingly, only the toxicity of NaF has been examined and not that of the more often used silicofluorides. In the present study, the toxicities of NaF, Na2 SiF6 , and H2 SiF6 were compared. The toxicity of these fluorides on the growth, feeding, and reproduction in the alternative toxicological testing organism Caenorhabditis elegans was examined. Exposure to these compounds produced classic concentration-response toxicity profiles. Although the effects of the fluoride compounds varied among the 3 biological endpoints, no differences were found between the 3 compounds, relative to the fluoride ion concentration, in any of the assays. This suggests that silicofluorides have similar toxicity to NaF.

Fluoride in Drinking Water May Be Toxic to Sperm
First a bit of background… sodium fluoride was the first of the fluoride waste materials to be used for fluoridation, but now is rarely used. It’s the most well known, as this is ‘pharmaceutical grade’ compound used in toxicology studies and other research into the potential health dangers of fluoride.
The other two types of fluoride, sodium silicofluoride and hydrofluorosilicic acid, are the compounds actually used for water fluoridation. Sodium silicofluoride and hydrofluorosilicic acid are the waste products from the fertilizer industry and are actually classified as hazardous wastes.
The new study compared the toxicity of three fluoride compounds – sodium fluoride and two silicofluorides used for water fluoridation – to determine their effect on the growth, feeding and reproduction of roundworms. They found:1
“Exposure to these compounds produced classic concentration-response toxicity profiles… This suggests that silicofluorides have similar toxicity to NaF [sodium fluoride].”
Since sodium fluoride appears to be equally toxic as the fluoride chemicals added to drinking water, it raises serious concern about another recent study, which found sodium fluoride may damage sperm chemotaxis, the process by which sperm are attracted toward an egg, which plays a critical role in allowing fertilization to occur.2 Though this study involved mice, if the findings apply to humans it could put men at risk of becoming infertile…
Fluoride May Be Dangerous to Male Fertility
Past research, too, has shown that fluoride has potentially disastrous effects on the male reproductive system. The Fluoride Action Network (FAN) reported:3
- Exposing ram semen to 0.38 parts per million (20 umol/L) of fluoride for five hours caused a “statistically significant decrease in the motility of spermatozoa” along with other changes that would “undoubtedly affect the physiological function of the sperm.”
- Infusing testes with modest amounts of fluoride (4.75 parts per million) inhibited the synthesis of testosterone
- Sixty animal studies have found that fluoride adversely impacts the male reproductive system, including:
- Decreases in testosterone levels
- Reduced sperm motility
- Altered sperm morphology
- Reduced sperm quantity
- Increased oxidative stress
- Reduced capacity to breed
It’s not only animal studies that have shown an emerging problem, however. As FAN explained:4
“Consistent with the in vitro and animal research, studies of human populations have reported associations between fluoride exposure and damage to the male reproductive system. Most notably, a scientist at the Food & Drug Administration [FDA] reported in 1994 that populations in the United States with more than 3 ppm fluoride in their water had lower ‘total fertility rates’ than populations with lower fluoride levels …
While 3 ppm is a higher concentration than used in water fluoridation programs (0.7 to 1.2 ppm), it is still considered a ‘safe’ level by the EPA. To date, no U.S. health agency has attempted to replicate… [these] findings.
However, three studies of highly fluoride-exposed populations in China and India have found that high fluoride exposure is associated with reduced male fertility. In addition, five studies from China, India, Mexico, and Russia have found that high-fluoride exposure is associated with reduced male testosterone levels.”
Fluoride Is an Undeniable Poison to Your Entire Body
Study after study has confirmed that fluoride is a dangerous, toxic poison that bio-accumulates in your body while being ineffective at preventing dental decay. For instance, there are 25 studies showing that fluoride reduces IQ in children, and approximately 100 animal studies have also linked fluoride to brain damage.5
One particularly striking animal study6 showed that fluoride ingestion had a profound influence on the animals’ brains and altered behavior. Pregnant rats given fluoride produced hyperactive offspring. And animals given fluoride after birth became apathetic, lethargic “couch potatoes.” Other research has linked fluoride toxicity with the wide-ranging problems listed below.
- Increases lead absorption
- Disrupts collagen synthesis
- Increases manganese absorption, which is also linked to lower IQ in children
- Crippling skeletal fluorosis and bone fractures
- Genetic damage and cell death
- Increased tumor and cancer growth
- Disrupts immune system
- Inhibits antibody production
- Brain damage, and lowered IQ
- Severe eye problems, includingblindness
- Impaired thyroid function
- Bone cancer (osteosarcoma)
- Inactivates 62 enzymes
- Muscle disorders
What’s Better Than Fluoride for Preventing Cavities?
Well, practically anything, since ingesting fluoride in drinking water does NOT decrease rates of tooth decay. In all seriousness, anyone who has ever read Dr. Weston Price’s book Nutrition and Physical Degeneration will soon recognize that diet is the most important factor in dental health.
Dr. Price wrote this book in 1920 and it is full of pictures of cultures with excellent dental health that rapidly deteriorated once processed Western food was introduced. When Dr. Price studied these native diets, he noticed some similarities in the foods that kept them so healthy. Among them:
- The foods were natural, unprocessed, and organic (and contained no sugar except for the occasional bit of honey or maple syrup).
- The people ate foods that grew in their native environment. In other words, they ate locally grown, seasonal foods.
- Many of the cultures ate unpasteurized dairy products, and all of them ate fermented foods.
- The people ate a significant portion of their food raw.
- All of the cultures ate animal products, including animal fat and, often, full-fat butter and organ meats.
I believe that if you have an optimal diet, without processed foods and sugars from infancy, you can be virtually assured of cavity-free teeth. All of the brushing and flossing in the world will not give you the healthy teeth that following the eating patterns described above will, so if you value your pearly whites, get started eating a healthier diet today.
When the U.S. Public Health Service endorsed water fluoridation in 1950, there was little evidence of its safety. Now, six decades later and after most countries have rejected the practice, more than 70 percent of Americans, as well as 200 million people worldwide, are drinking fluoridated water. The Center for Disease Control and the American Dental Association continue to promote it–and even mandatory statewide water fluoridation–despite increasing evidence that it is not only unnecessary, but potentially hazardous to human health.
In this timely and important book, Dr. Paul Connett, Dr. James Beck, and Dr. H. Spedding Micklem take a new look at the science behind water fluoridation and argue that just because the dental and medical establishments endorse a public health measure doesn’t mean it’s safe. In the case of water fluoridation, the chemicals that go into the drinking water that more than 180 million people drink each day are not even pharmaceutical grade, but rather a hazardous waste product of the phosphate fertilizer industry. It is illegal to dump this waste into the sea or local surface water, and yet it is allowed in our drinking water. To make matters worse, this program receives no oversight from the Food and Drug Administration, and the Environmental Protection Agency takes no responsibility for the practice. And from an ethical standpoint, say the authors, water fluoridation is a bad medical practice: individuals are being forced to take medication without their informed consent, there is no control over the dose, and no monitoring of possible side effects.
At once painstakingly documented and also highly readable, The Case Against Fluoride brings new research to light, including links between fluoride and harm to the brain, bones, and endocrine system, and argues that the evidence that fluoridation reduces tooth decay is surprisingly weak.
