  • Evaluation of the toxicity of fluorine in Antarctic krill on soft tissues of Wistar rats

    Antarctic krill are a potential food source for humans and animals, but krill are known to contain high levels of fluorine (F). In this study, we investigated the toxicity of F in Antarctic krill using Wistar rats. There were three experimental groups: The control group were fed a basal diet,

  • Effects of fluoride ingestion on the physiology of reproductive organs of male rat

    Oral administration of sodium fluoride (NaF) (5 and 10 mg/kg body weight/day) for 30 days to adult male rats, brought about a reduction in body weight especially by high dose (10 mg/kg body weight). In fluorotic rats, testicular cholesterol and serum testosterone levels were not affected. However, succinate dehydrogenase activity

  • Fluoride + aluminum induced toxicity in mice testis witih giant cells and its reversal by vitamin C

    Administration of sodium fluoride (NaF, 10 mg/kg bw) together with aluminium chloride (AlCl3, 200 mg/kg bw) to adult male mice for 30 days resulted in structural alterations in the testis with formation of giant cells. These changes along with lower protein levels affected spermatogenesis. Steroidogenesis was also altered since the

  • [The primary study of antagonism of selenium on fluoride-induced reproductive toxicity of male rat].

    The protective effect of ascorbic acid at dose level of 1.0 mg/L in drinking water against the fluoride-induced damage on reproductive system of rat was studied. 150 mg/L sodium fluoride (NaF) in drinking water of male rat can cause the significant decrease of sperm count and mobility, the increase of

  • Suppression of male reproduction in rats after exposure to sodium fluoride during early stages of development

    Sodium fluoride (NaF), a widespread natural pollutant was given to sperm-positive female rats throughout gestation and lactation at a dose of 4.5 and 9.0 ppm via drinking water. The neonates were allowed to grow up to 90 days on tap water, and then sperm parameters, testicular steroidogenic marker enzyme activity

  • 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: Developmental Neurotoxicity.

    Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching

  • 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's Effect on Male Reproductive System -- The "Sprando/Collins" Anomaly

    In contrast to the findings of over 60 animal studies from other research teams, a series of studies by FDA researchers Sprando & Collins reported virtually no evidence of reproductive toxicity among animals treated with very high levels of fluoride exposure. The reasons for this discrepancy remains unclear. Excerpts from Sprando/Collins' Studies: "This study

  • Fluoride Affects Learning & Memory in Animals

    An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out
