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

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

Vitamin C and E supplementation can ameliorate NaF mediated testicular and spermatozoal DNA damages in adult Wistar rats.
Objective: Present study was designed to explore the efficacy of vitamin C and E (VC&VE) against fluoride mediated testicular, epididymal and spermatozoal anomalies. Materials and methods: Thirty two adult Wistar rats were divided into four groups. Group-I was control; Group-II received sodium fluoride (NaF) at 15 mg/kg/day

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

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 & Rickets
One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid (unmineralized bone) content of bone. When bones have too much osteoid, they become soft and prone to fracture -- a condition known as osteomalacia. When osteomalacia develops during childhood, it is called "rickets." The potential for fluoride

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 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.

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.
