The effect of 100, 300 and 500 mg/kg of ethanol extract of ricinus communis extract on reproductive hormone: estrogen, progesterone, LH and FSH was investigated using virgin female albino wistar rats. The results showed that at lower doses ricinus communis extract caused a decrease in estrogen, progesterone and LH levels at P < 0.05, but at high dose of 500mg/kg it caused an increase in estrogen, progesterone levels at P < 0.05. The extract did not have significant effect on FSH at P > 0.05.  Data suggested that the extract increased the hormones in a dose-dependent fashion.     Keywords.
