Abstract

This study was aimed to evaluate the effects of Quercetin to improve efficiency of the female reproductive system of wester rats which exposed to oxidative stress by lead acetate. 40 mature female rats were used with weights at (180± 20 gm) and randomly divided into equal 4 groups (10 animals in each group). group 1(control group) received drinking water freely, group 2: administered Querctin (300mg/kg) orally once daily for 60 days, group 3: administered daily dose of lead acetate (10mg /kg) orally, once daily for 60 days and group 4: administered daily dose of lead acetate (10mg/kg) orally for 30 days and then administered Quercetin (300mg/kg) orally once daily for another 30 days. after 60 days the animals were sacrificed and samples of ovary and pituitary glands was taken for gene expression study for Aromatase cytochrome P450 gene, FSH beta subunit gene and FSH receptor gene The results were as follows: gene expression of estrogen showed a significant increase (p0.05) in compared with other groups, also there was a significant increase(p
