Abstract

Treatment of adult male mice with sodium fluoride (NaF, 10 mg/kg bw/ day) and aluminium chloride (AlCl 3 , 200 mg/kg bw/day) simultaneously for 30 days caused marked histological changes in the epididymis accompanied by decreased levels of protein and sialic acid and also lowered activities of adenosine triphosphatase (ATPase) and succinate de hydrogenase (SDH) in caput and cauda epididymides with evident alteration of sperm maturation in mice. Withdrawal of NaF+AlCl 3 for 30 days led to significant recovery in all parameters except ATPase. Simultaneous treatment with NaF+AlCl 3 +vitamin C, however, resulted in significant recovery in both regions of the epididymides. These results indicate that the toxic effects are similar in the two regions, but among the parameters studied, ATPase seems to be the most sensitive and would likely affect sperm metabolism and motility.

  • 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'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 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.

    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
