Abstract
Background and objective: There is increasing evidence for the role of oxidative stress in female reproductive tract. The purpose of this study was to determine the activity of antioxidant enzymes during menstrual cycle. In addition, the relationship between activity of antioxidant enzyme and sex hormones was evaluated.
Materials and methods: In this study the activity of superoxide dismutase, glutathione peroxidase, glutathione reductase, catalase and total antioxidant capacity during the menses, follicular and luteal phases of the menstrual cycle in twenty women with regular menstrual cycle were studied. Furthermore, the correlation between activity of antioxidant enzymes and estradiol, progesterone, LH, FSH and testosterone were evaluated.
Results: There was no significant difference between activity of superoxide dismutase, glutathione peroxidase, glutathione reductase, catalase and total antioxidant capacity during the menses, follicular and luteal phases of the menstrual cycle (P>0.05). We found significant correlation, in luteal phase, between superoxide dismutase and FSH (P<0.05، r=0.44) and LH P<0.05،r=0.54). Also it is observed between LH and glutathione peroxidase (P<0.05، r=0.44).
Conclusion: Based on the results, there is no significant difference between antioxidant enzymes and total antioxidant capacity of plasma during menstrual cycle. In other words, physiologic system of women with regular menstrual cycle can protect body against oxidative stress and this is probably performed due to action of FSH and LH hormones.

Abstract
Background and Objectives: Ciprofloxacin is a synthetic antibacterial agent belonging to Fluoroquinolone drugs affecting effectively on gram-negative bacterial infectious. The aim of this study was to assess the effect of ciprofloxacin in the spermatogenesis period.
Material and Methods: The subjects were 20 male wistar rat randomly divided in to control (n=10) and experimental group (n=10), given 12.5mg/kg ciprofloxacin (soluble in drinking water) in spermatogenesis period. On the day of 28, the sperm was collected from cauda epididymis and sent for analysis.
Results: Based on light microscopic observation and statistical analysis, the majority of seminiferous tubules of control group were healthy, in Sc 8-9 stage. But in test group, sertoli cell degeneration and absence of sex cells were confirmed, and in some parts, just basal layer of seminiferous tubule was remained in Sc 3-5 stage.
Conclusion: Sex hormones (LH and FSH) and spermatogenesis (sperm count, motility and viability) were significantly decreased in test group compared to those of controls (P<0.05). Ciprofloxacin has some adverse effects on sperm related variables in 28 day period.
