Abstract
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 + AlCl3 treatment and by administering ascorbic acid (AA), calcium (Ca), or vitamin E alone and in combination were also investigated. All treatments (NaF, AlCl3 , and NaF + AlCl3) resulted in a significant decline of ovarian protein and 3B-and 17B-hydroxysteroid dehydrogenase activities which could be related to increased cholesterol levels in the ovary suggesting altered steroidogenesis. The treatment also caused a hypercholesterolemic effect in serum. Accumulation of glycogen in uterus could be related to inhibition of phosphorylase activity affecting carbohydrate metabolism. The withdrawal of combined treatment for 30 days brought about an incomplete recovery. How-ever, AA, Ca, or vitamin E supplementation alone and in combination produced an additive effect for recovery of most of the parameters almost to con-trol levels. Hence the effects of NaF and/or AlCl3 are transient and reversible.

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

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

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

Management of fluoride induced testicular disorders by calcium and vitamin-E co-administration in the albino rat
Fluoride contamination of drinking water can disrupt male gametogenesis and steroidogenesis and induce testicular oxidative stress. Treatment of rats with sodium fluoride at the dose of 20 mg/kg/day for 28 days resulted in significant diminution of testicular Delta5,3beta-hydroxysteroid dehydrogenase (HSD) and 17beta-hydroxysteroid dehydrogenase (HSD) activities and low plasma levels of

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,

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

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

Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur

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
