The results of studies conducted until now does not determine what the best way to treat infertility in the first line with patients with Polycystic ovary syndrome (PCOS). This study objective is to determine the best treatment for such patients. The long-term consequence health of women with PCOS are multiple. The woman with PCOS has a risk of developing metabolic diseases, heart diseases, diabetes Type II or anovulatory infertility. The insulin resistance plays an important role in all this medical condition. Clomiphene Citrate (CC) remains the first line treatment to induce ovulation in women with PCOS and anovulatory infertility.
