Background and Aim: Valsartan as a receptor antagonist angiotensin-II (AngII) is used to treat blood pressure disorders and affects various tissues of the body. Thus,the present study was performed to investigate the effect of Valsartan on the axis of the pituitary-gonadal axis in mature female rats. Materials and Methods: In this research, 40 mature female Wistar rats were randomly divided into 8 member groups including control, sham and experimental groups. Initially, all the animals were homogenized through intramuscular injection of estradiol valerate and progesterone. Then the animals of sham group daily received 1 ml of olive oil (solvent) and the experimental groups were gavaged daily doses of 100, 200 and 400 mg/ Kg Wt , of Valsartan The control group members were not Administered anything. All drugs were administered for 21 days and at the end of the period, through deriving blood from the heart of animals the required serum was prepared by means of relevant hormonal kits to measure the levels of FSH, LH, estrogen and progesterone. The obtained data was evaluated using ANOVA and Tukey tests ,and P< 0/05 was taken as the significant level. Results: Statistical results analysis showed that Valsartan caused a significant reduction in hormones of FSH, LH, estrogen and progesterone. Conclusion: Valsartan , as a receptor antagonist of Ang II inhibits the secretion of gonadotropin hormones and accelerates their effect on blocking the follicular cells of the female sex ,causing the reduction of female hormones.
