title: Ascorbic acid treatment elevates follicle stimulating hormone and testosterone plasma levels and enhances sperm quality in albino Wistar rats.
abstract: BACKGROUND
  Infertility issues have been linked to the effect of oxidative reaction in the reproductive system. This study evaluated the effect of ascorbic acid, on fertility parameters of male albino Wistar rats was studied.
  
  
  METHODS
  Eighteen albino Wistar rats weighed between 178 g and 241 g were used, randomly assigned into three groups. Group 1 was the control group; oral gavaged 5 ml of distilled water; Groups 2 and 3 were administered medium dose (250 mg/kg) and high dose of ascorbic acid (400 mg/kg), respectively; twice daily for 21 days. Blood samples were obtained by cardiac puncture, and blood serum was obtained for hormonal assay, and the testes were harvested for sperm analysis.
  
  
  RESULTS
  Follicle stimulating hormone levels significantly increased in the high-dose group as compared to both the control and medium dose groups. Luteinizing hormone levels in the medium dose group decreased significantly as compared to the control group. Testosterone significantly increased in both the medium- and high-dose groups as compared to the control group. Sperm motility increased significantly in the high-dose group as compared to both control and medium-dose groups. Percentage sperm concentration decreased significantly in the medium-dose group when compared to the control and increased significantly in the high-dose group as compared to the medium-dose group. For percentage normal morphology, there was a dose-dependent increase in the test groups when compared to control group.
  
  
  CONCLUSIONS
  These results are indicative of a positive influence of ascorbic acid on male fertility modulators and may therefore, serve as a potential adjuvant treatment for male infertility cases.
