Abstract
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 rats produced reduction in weights of ovaries, uterus, vagina, kidneys, and adrenal glands, circulating levels of estrogen, number of litters, fertility rate, and altered tissue and serum biochemistry compared to control rats. However, cholesterol concentrations of ovaries and adrenals increased significantly. The above altered parameters were restored partially/completely after exogenous feeding with vitamin C and vitamins (C + D) and calcium. The data suggest that Fl-induced adverse effects on reproductive and other organs in female rats, whereas vitamin C, vitamin D and calcium treatment ameliorated Fl toxicity. Therefore, vitamins (C and D) and calcium play an important role in prophylactic treatment of fluorosis.

Amelioration of fluoride toxicity in some accessory reproductive glands and spermatozoa of rat
Sodium fluoride (NaF) at a dose of 10 mg/kg body weight was administered orally to male rats (Rettus norvegicus) daily for 30 and 50 days to evaluate the effect of the physiology of some sex accessory glands and sperm functions. The effects of withdrawal upon cessation of NaF ingestion, and

Reversal of fluoride-induced alteration in cauda epididymal spermatozoa and fertility impairment in male mice
The effects of sodium fluoride (NaF) ingestion (10 mg NaF/kg body weight) and the possible therapeutic effects of ascorbic acid (AA, 15 mg/animal/day) and/or calcium phosphate (Ca, 25 mg/animal/day) on the reproductive functions and fertility of male mice were investigated. NaF-ingestion brought about a significant decline in sperm acrosomal acrosin

Mitigating effects of some antidotes on fluoride and arsenic induced free radical toxicity in mice ovary
The effects of oral administration of sodium fluoride (NaF) and/or arsenic trioxide (As(2)O(3)) (5 mg and 0.5 mg/kg body weight, respectively) for 30 days were investigated on free radical induced toxicity in the mouse ovary. The reversibility of the induced effects after withdrawal of NaF+As(2)O(3) treatment and by administration of

Amelioration of fluoride toxicity in rats through vitamins (C, D) and calcium
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

Efects of sodium fluoride and aluminium chloride on ovary and uterus of mice and their reversal by some antidotes
A study was made of the effects on ovary and uterus of adminis-tering sodium fluoride (10 mg/kg body weight) or aluminium chloride (200 mg/kg body weight) alone and in combination to female albino mice (Mus musculus) for 30 days. The reversibility of the induced effects by withdrawal of NaF +

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'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.

Fluoride Exposure Aggravates the Impact of Iodine Deficiency
A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and

Fluoridation, Dialysis & Osteomalacia
In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

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.
