Fluorosis: geographical pathology and some experimental findings

October 1981 | Fluoride | Zahvoronkov AA, Strochkova LS. | 14(4):182-91.
A.P. Tarinsky (4) revealed a 2-3 fold increase of symptoms of oligospermia and azoospermi a in male W¢rkers suffering from industrial fluorosis compared with healthy men o f the same age. Tokar (5, 6) found an association between fluorosis and hypogonadism. These data made it necessary to study the changes of synthetic processes in the testes of mice in experimental fluorosis. A total scintillation method of probe computing on the counter revealed certain shifts of RNA and prote in metabolism i

In vitro inhibition of testosterone synthesis in the presence of fluoride ions

1983 | IRCS Medical Science | Kanwar KC, Vig PS, Kalla NR. | 11: 813-814.
A marked fall (p < 0.01) in the testosterone production was recorded at a fluoride concentration of 100 ppm and testosterone synthesis was maximally inhibited (p < 0.01) at 200 ppm. There was a noticeable, though marginal, inhibition in testosterone synthesis even at 10 ppm fluoride concentration. From 1 ppm to 200 ppm, the degree of inhibition of testosterone synthesis seems to be dependent on fluoride concentration.
