The present research report has looked into the correlation between male infertility and the fluoride level in water, the occurrence of dental and skeletal fluorosis, [the volume and quality of] semen and the amount of fluoride contained therein. Results have shown that fluoride might be a leading cause of male infertility in regions with endemic fluorosis.
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
The effect of the fluoride ion on reproductive parameters and an estimate of the safe daily dose of fluoride to prevent female infertility and miscarriage, and foetal neurotoxicity.
A paper in the current issue by Yousefi et al. examined data on the prevalence of fertility, infertility, and abortion (miscarriage), in the health records of 3,392 women, aged 10–49 yr, living in two regions of Poldasht county, Iran, with low and high drinking water fluoride ion (F) levels (means
Reproductive toxic effects of ingestion of sodium fluoride in female rats
The objective of this study was to investigate the toxic effects of different concentrations of sodium fluoride (200, 400 and 600 ppm NaF), administered in drinking water for 30 days, on the reproductive system of adult female Sprague-Dawley rats. The rats in the two higher-dosed groups showed clinical signs of
[Fluorosis of coal burning affects the male reproductive system].
Fluorosis of coal burning is a new type of endemic fluorosis in China, which affects the male reproductive system. Furthermore, the content of fluoride in the semen, sperm mortality, sperm concentration and the incidence of infertility are higher in severe fluorosis areas than in mild- and non-fluorosis areas, so are
The influence of excess fluorine intake in the drinking water on reproductive efficiency in bovines
Observations were made over four breeding seasons to determine the effect of excessive intake of fluorine in the drinking water on the breeding efficiency of cattle. Fifty Afrikaner heifers, maintained under ordinary ranching conditions, were divided into five groups which received 5, 8 and 12 ppm fluorine respectively in the drinking
