Many dental products contain dangerously high levels of fluoride. For years, manufacturers and dentists failed to warn consumers about the risks from ingesting these products. Although the FDA now requires manufacturers to warn consumers that fluoride products are poisonous when swallowed, manufacturers and dentists are still using these products in ways that expose consumers and patients to potentially toxic levels of fluoride.
Fluoride’s Effect on Male Reproductive System: Animal Studies
Over 60 studies on animals (including rats, mice, roosters, and rabbits) have found that fluoride adversely impacts the male reproductive system. These studies have repeatedly found the following effects: (1) decreases in testosterone levels; (2) reduced sperm motility; (3) altered sperm morphology; (4) reduced sperm quantity; (5) increased oxidative stress; (6) and reduced capacity to breed.
Male infertility is responsible for about 50% of the fertility problems that couples face. Infertility in males is often the result of reduced sperm court, abnormal sperm quality (e.g., reduced motility and altered morphology), or altered levels of sex hormones (e.g., reduced testosterone). A review of over 100 studies of sperm density from 1938 to […]
Fluoride’s Effect on Male Reproductive System – Human Studies
Consistent with 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 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.
Fluoride’s Effect on the Male Reproductive System — In Vitro Studies
Carefully controlled in vitro studies have found that direct exposure of fluoride to the testes or semen inhibits testosterone production and damages sperm. While researchers have known since the 1930s that mega concentrations of fluoride can completely (but reversibly) immobilize sperm, it was not until the 1970s and 1980s that researchers found that relatively modest concentrations of fluoride could cause damage prior to complete immobilization.
Prenatal and postnatal ingestion of fluorides – A progress report.
The cases described indicate that certain patients react unfavorably to fluoride therapy. Whether the fluorine acts as an allergen after short term use or whether the fluorine acts as an intoxicant after many months of use, is unknown and should be determined.
Fluoride Dentrifice and Stomatitis
Statistical data of 133 patients who have been using fluoride dental cream or powder have been presented. Each has developed intraoral ulcerative lesions. Many have been treated for other complaints without clearance of the lesions. Age is not significant. Repeated insults with the fluoride dentrifices produced increasingly severe excoriations. There seems to be nothing specific about the lesions to differentiate them from other diseases of an oral nature.
Allergic Reactions from Fluorides
Six cases are described with allergic manifestations from fluorides. The symptoms were reproduced by administering an aqueous fluoride solution either by ingestion, injection or local application. Control tests had no such effect. The patients had no way of knowing which solution contained fluoride.
Allergy to Fluoride
Six children and one adult exhibited various allergic reactions after the use of toothpaste and vitaimin preparations containing fluoride. The following conditions were encountered: Urticaria, exfoliative dermatitis, atopic dermatitis, stomatitis, gastro-intestinal and respiratory allergy.
Fluoride Toothpaste: A Cause of Acne-like Eruptions
I feel that I should share with my colleagues in dermatology an observation relative to the treatment of problem acne.
