title: Study of Foeniculum vulgare Effect on Folliculogenesis in Female Mice.
abstract: BACKGROUND
  Foeniculum vulgare (FVE) is used in traditional medicine for its antiseptic, palliative and anti-inflammatory effects. Traditionally, FVE is utilized for treating female infertility. The present study aims to investigate the effects of FVE extract on folliculogenesis in female albino mice.
  
  
  METHODS
  In this experimental study, a total of 20 female albino mice were divided into four groups. Groups 1 and 2 (experimental) received FVE alcoholic extract at doses of 100 and 200 mg/kg body weight (BW)/day for five days. Group 3 (negative control) received ethanol and group 4 (positive control) was administered normal saline, in the same doses as the experimental groups. Animals in all groups were sacrificed on the sixth day of the study; their ovaries were dissected out and prepared for histological examinations. Hematoxylin and eosin (H&E) stained microscopic slides were evaluated and the numbers of ovarian follicles were compared between groups. Data were analyzed by one way ANOVA.
  
  
  RESULTS
  The total follicle numbers were 26.5 ± 5.24 for group 1 (100 mg/kg FVE), 27.2 ± 4.1 for group 2 (200 mg/kg FVE), 10.1 ± 2.53 for group 3 (ethanol control) and 17.2 ± 3.9 for the saline control group (group 4). The numbers of graffian, antral and multilaminar follicles increased significantly in both experimental groups when compared with the control groups (p<0.05), however there were no significant differences in follicle numbers among the experimental groups. The number of unilaminar primary follicles did not significantly change between all groups. GCMS analysis of FVE extract identified the presence of diosgenin, an estrogenic compound.
  
  
  CONCLUSIONS
  FVE induced folliculogenesis in female mice ovary and increased the number of growing ovarian follicles. The estrogenic component of FVE, diosgenin, may exert this effect.
