Objective: To investigate the effects of folic acid on testicular
oxidative damage in sodium fluoride-induced male Wistar rats.
Methods: A total of 24 male Wistar rats were divided into 4
groups: the control, sodium fluoride (fed with 100 mg/L sodium
fluoride through drinking water orally for 21 days), folic acid
(36 µg/kg body weight/day, orally), and sodium fluoride plus
folic acid (received similar dose orally) groups. At the end of
21 days, epididymal sperm parameters, biochemical analysis
of testicular tissue, and serum hormonal levels were performed
along with histopathological studies.
Results: Sodium fluoride intoxication resulted in marked
reduction in gonado somatic index, serum luteinizing
hormone, and testosterone level along with 3 毬 -hydroxysteroid
dehydrogenase and 17 毬 -hydroxysteroid dehydrogenase
activities. In addition, reduction in sperm density, as well as
loss of sperm motility and sperm viability, were also observed.
Besides, increased levels of testicular malondialdehyde, nitrite,
interleukin-6 and tumor necrosis factor- 毩 as well as decreased
levels of superoxide dismutase and catalase activities and
reduced glutathione content were found to be associated with this
toxicity. Folic acid co-treatment, on the other hand, could prevent
all the sodium fluoride-induced testicular pathophysiology and
oxidative stress related parameters. Histological examinations
of testicular sections from the experimental rats supported
these results.
Conclusions: Combining all, this study suggests that being an
antioxidant, folic acid plays a beneficial role against fluoride-
induced adverse effects on the male reproductive system.
