In this research the effect of ovulating induction among this group of<br />women was compared with the women with normal ovary and tubal sterility.<br /><strong>Methods:</strong> This prospective cohort study performed on 260 infertile pairs with PCOS and tubal factors under treatment using<br />fertility assistance techniques in IFIC. The numbers of oocyte, concentration of testosterone and andrestandion, fertility<br />rate and embryo quality were compared.<br /><strong>Results:</strong> The mean of oocyte retrieved, concentration of andrestandion in follicular and LH0 phases, and testosterone in<br />LH0 phase were higher in PCOS patients (p < 0.05), but the fertilization rate indicated no difference between two groups.<br />According to the results there was a significant association between the concentration of andrestandion and testosterone<br />phase LH0 and the embryo quality.<br /><strong>Conclusion:</strong> The ovulation induction in PCOS by increasing the serum androgen concentration would lead to undesirable<br />influence on oocyte, so that the achieved embryo has a lower quality and the ratio of good-quality embryo decrease, but<br />because of the high number of oocyte and the number of achieved embryo in the women with PCOS the chance of growing<br />more good-quality embryo is high<br /><strong>Key words</strong>: Polycystic ovary syndrome, ovulation induction, number of oocyte, androgenhttp://ijnmr.mui.ac.ir/index.php/ijnmr/article/view/44http://ijnmr.mui.ac.ir/index.php/ijnmr/article/download/44/44
