Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders, can be associated with problems, such as hyperandrogenism, chronic anovulation and infertility. Ginger and its active components, have powerful anti-inflammatory and antioxidant effects. Cyclooxygenase-2 (COX-2) is the enzyme in the biosynthesis of prostaglandins and operates as an inducible enzyme with a number of inflammatory stimuli like PCOS. In this research, we evaluated the effects of ginger extract on ovarian COX-2 gene expression and reproductive improvement in PCOS rats.

After induction of PCOS (by Estradiol Valerate injection), the rats divided into, control, PCOS control, PCOS treated with ginger extract (150 and 300 mg/kg) groups. At the end of treatment period, biochemical factors were measured by ELISA kits and histological assessment was done. Then RNA isolation and cDNA synthesis of ovarian tissues was performed. The data were analized by one way ANOVA ,followed by Tucky test and gene expression data were evaluated by using ΔΔCT method. Statistical significance level was set at P<0.05.

Administration of ginger extract to PCOS treated groups, led to improved gonadotropin, sex steroids and ovarian functioning. In addition, treatment of the PCOS group with 300 mg/kg of ginger extract caused to reduce COX-2 gene expression significantly (P<0.01).

Ginger extract can act as a natural anti-inflammatory agent, and can use as a replacement of conventional synthetic anti-inflammatory drugs, in the chronic inflammatory conditions like PCOS.

PCOS (polycystic ovary syndrome) is the most common endocrine and metabolic disorder characterized by amenorrhea, hyper androgens, hirsutism, chronic anovulation and infertility. The aim of the present study was determining the effects of ginger extract, and 6-gingerol on hormonal levels and ovarian follicles in induced PCOS rats, and comparing the ameliorating effects of these two substances for treatment of PCOS.

In this experimental research, 42 adult female Wistar rats weighting between 160 g-180 g were divided into six groups of 7 animals. PCOS control that received no injection. PCOS received intraperitoneal injections of 100 mg/kg of ginger extract (for 28 days). Statistical analyses with SPSS, one-way ANOVA, T-test and Duncan test wereused to compare groups.

In comparison with PCOS control, the treatment of PCOS rats with ginger extract (100 and 200 mg/kg) and 6-gingerol (200 and 400 µg/kg) led to significant decrease in LH levels. There was a decrease in FSH levels, but the significant one was only in the 6-gingerol treated group (400 µg/kg). In PCOS treated groups with gingerextract and 6-gingerol, the serum levels of estradiol decreased significantly compared to control and PCOS control groups (P<0.001). Progesterone levels in PCOS groups injected with ginger extract and 6-gingerol showed a significant increase (P<0.05). In PCOS treated groups with ginger extract and 6-gingerol, testosterone levels decreasedsignificantly (P<0.001, P<0.01, P<0.05).

6-gingerol and ginger extract may be a useful treatment for improving the PCOS through reduction of estrogen, testosterone, LH and FSH, and improvement of ovulation. In fact, because of anti-inflammatory and antioxidant properties of ginger components, especially 6-gingerol, they can cause to improve PCOS
