Ovarian protection in cyclophosphamide-treated mice by fennel

- Morphological parameters (WVD) in CP-treated groups significantly reduced.
- Female sexual hormones in CP-treated groups significantly decreased.
- CP-treatment lead to a reduction in the number of different ovarian follicles.
- Fennel extract significantly ameliorate cyclophosphamide ovarian damages.

Evaluation of protective effect of fennel on mouse ovary against the destructive effects of cyclophosphamide (CP) was the aim of this study. Adult female NMARI mice were randomly divided into six groups (n = 8): (A) negative control, (B) CP200 mg/kg, (C) fennel 400 mg/kg/day, (E, F, and D) that received fennel 200, 400 and 100 mg/kg/day respectively + CP200 mg/kg. Their ovary weight, volume, and diameter (WVD) were measured. Five micron sections were stained using the H&E method. The serum levels of oestrogen and progesterone were measured using ELISA kit. The results showed that WVD significantly reduced in the CP-treated groups in comparison with the A and C, but WVD increased after treatment of the mice with fennel extract, in comparison with B group. A significant decrease of serum in terms of oestrogen and progesterone levels among CP-treated groups in comparison with the A group was observed. In the CP-treated groups a reduction in the number of different ovarian follicles in comparison with the A and C groups was observed. However, in the treated animals with fennel extract, these parameters significantly increased in comparison with the B group. Finally, it is concluded that fennel can protect ovary from cyclophosphamide side effects.
