Abstract
The healthy, adult male rats (Rattus norvegicus) were treated with fluoride water (F.W.+5.8 ppm), F.W.+ ascorbic acid and F.W. + vitamins (C, D) and Ca+2 for 60 days. Fluoride water ingestion to rats for 60 days resulted in significant reduction of seminal vesicle weight, sperm motility and sperm density of cauda epididymis and testis as compared to control values. The level of testosterone diminished significantly leading to reduced fertility and numbers of litters. The total erythrocytes number, hemoglobin and haematocrit value declined. The concentration of protein, fructose and ascorbic acid decreased, whereas, the cholesterol concentration of testis and enzyme activity of acid phosphatase increased significantly (P<0.001) as compared to control value. The exogenous feeding of ascorbic acid and vitamin C, vitamin D and calcium along with fluoride water for 60 days caused recovery in all altered parameters studied including circulating level of testosterone, blood physiology, sperm function and fertility. The data suggest that ascorbic acid and vitamin C, vitamin D and Ca +2 treatment can play a prophylactic role to maintain normal physiology in fluoride toxicity.

Evaluation of vitamin E and calcium effects on fluoride toxicity-induced fertility impairment
Chronic fluoride (Fl) toxicity is a serious public health problem globally where drinking water contains more than 1 ppm of Fl. Sodium fluoride (NaF) produced male reproductive system toxicity. The aim of the present study was to evaluate the amelioration of Fl toxicity-induced fertility impairment by vitamin E and calcium

Fluoride toxicity in the testis and cauda epididymis of guinea pig and reversal by ascorbate
Effects of sodium fluoride (NaF) (30 mg kg-1 body weight) and ascorbic acid ingestion along with sodium fluoride for 30 days each were studied to evaluate its possible role as an ameliorative agent on functions of reproductive organs and spermatozoa of the fluorotic guinea pig. The cauda epididymal spermatozoa were

Sodium fluoride induced toxicity in testes of Swiss albino mice and its reversal by ascorbic acid and calcium
Fluorosis, which was considered to be a problem related to teeth and bone only, has now turned up to be a serious health hazard. The aim of this study is to see the effect of fluoride on the reproductive system and to see the role if any of Ascorbic acid

Amelioration of fluoride toxicity by vitamins and calcium on reproductive organs of female rat
Normal female rats of Wistar strain (Rattus norvegicus) weighing between 150–200 g were treated with fluoride (Fl) contaminated drinking water (FW, 5.8 ppm), vitamin C (6 mg) and vitamin C (6 mg) + D (6 mg once a week) + calcium (6 mg) for 30 days. Fl water treatment to

Fluoride toxicity on rat testis and cauda epididymal tissue components and its reversal
The toxic effects were evaluated of sodium fluoride (NaF) ingestion on the physiology of tissue components of testis and epididymis of adult, male albino rats, and the possible reversal of the effects by use of some antidotes. The results revealed that the testis and cauda epididymal proteins were altered, with

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

Fluoride Exposure Increases Metabolic Requirement for Magnesium
Fluoride's toxicity is significantly enhanced in the presence of nutritional deficiencies. Similarly, fluoride exposure increases the body's requirement for certain nutrients. An individual with a high intake of fluoride, for example, will need a proportional increase in calcium to avoid the mineralization defects (e.g., osteomalacia) that fluoride causes to bone

Fluoride Is Not an Essential Nutrient
In the 1950s, dentists believed that fluoride was a “nutrient.” A nutrient is a vitamin or mineral that is necessary for good health. Dentists believed that fluoride ingestion during childhood was necessary for strong, healthy teeth. A “fluoride deficiency” was thus believed to cause cavities, just like a deficiency of calcium can

Fluoride Exposure Increases Metabolic Requirement for Calcium & Vitamin D
It is well known that individuals with nutrient deficiencies are more susceptible to fluoride toxicity, including fluoride's bone effects. As discussed in the following studies, fluoride increases the skeleton's need for calcium (and vitamin D) by increasing the amount of unmineralized tissue (osteoid) in the bone. When insufficient calcium and

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.
