الملخص EN

The research work was conducted to investigate the effect of oral administration of water extract of black pepper at doses of (1, 5) mg / kg body weight for two weeks daily by determining the genotoxic effect (mitotic index), evaluation of immunological effect (IgG, IgM, IgA, C3, C4) and measuring fertility hormones (follicles stimulation hormone / FSH, luteinizing hormone / LH) levels with histopathologically examinations of female albino swiss mice ovaries in comparison with control (normal saline).

A clear effect in increasing mitotic activity was reveled for both doses in comparison with control.

Results also showed a significant increase in the value of the all immunological parameters at both doses in comparison with control.

Also obvious raise was seen in the level of FSH and LH for both doses when compared with normal saline treated mice with no significant damage seen in female ovaries tissue, in fact there were certain clinic pathological changes in mice ovaries tissue which were represented by increasing in the numbers of primary and secondary follicles and in the numbers of corpus luteum at both doses.
