Background: Polycystic ovary syndrome (PCOS) that occurs with chronic lack of ovulation, systemic inflammation and hyperandrogenism is manifested most common endocrine disorder in women of reproductive age. Ziziphora tenuior L. due to possess its Pulegone, flavenoid and anthocyanin has anti-inflammatory and anti-oxidant activity. This study investigates the modulating effects of Ziziphora tenuior L. extract by its anti-inflammatory properties on hormonal profile and the improvement of tissue symptoms of estradiol valerate- induced PCOS. Methods: In this experimental study that established in Laboratory,s Animal Center and Cellular And Molecular Research Laboratory, Kharazmi University, Karaj, from October 2012 to November 2013, 144 female adult Wistar rats divided into three groups of control (without injection), estradiol valerate- induced polycystic ovarian syndrome (2 mg/rat estradiol valerate, subcutaneously) and Ziziphora tenuior L. extract-treated groups. After induction of the syndrome within 60 days, experimental groups were injected 100, 150 and 200 mg/kg bw Ziziphora tenuior L. extract for 10 consecutive days intraperitoneally. The animals were anesthetized by chloroform. Their ovaries and blood serum was harvested to hormonal analysis and histomorphometric studies. Data using of one-way ANOVA test and P< 0.05 was considered significant level. Results: The ovarian sections in PCOS group exhibited a significant reduction in thickness granulosa layer (82%), number of corpus luteums (54%), appearance of some cysts (79%) and increased CRP serum level (68%) compared with the control group, while the histological changes in Ziziphora tenuior L. extract-treated ovaries did not have significant difference compared with control (P= 142). The decrease of LH, estradiol, and testosteron was significant in Ziziphora tenuior L. extract-treated groups compared with the estradiol valerate- induced PCOS. Conclusion: It seems that Ziziphora tenuior L. extract may improve functional and endocrine disturbances of estradiol valerate- induced PCOS and modulate the hormone level by anti-inflammatory effects. Ziziphora tenuior L. extract also starts the ovulation process again in polycystic ovary syndrome group.
