comparison of Letrozole and Clomiphene in combined regimens with gonadotropins in pregnancy rate in pcos patients with clomiphene resistant polycystic ovarian syndrome.
The aim of this study was to compare Letrozole and Clomiphene effects, in combination with Gonadotropins, on pregnancy rate in ovulation induction cycles in Clomiphene-resistant patients with polycystic ovarian syndrome. 120 patients with PCOS referred to kashan infertility clinic were enrolled in this randomized clinical trial and were randomly assigned to receive 100mg Clomiphene citrate or 5mg Letrozole daily on days 3 – 7 of menstrual cycle. Patients on both groups received 150IU HMG intramascularly on days 5 – 8 of menstrual cycle, as well. On tenth or eleventh day of menstrual cycle, transvaginal sonography was performed in order to determine endometrial thickness and dominant follicle size and HMG dose was increased, if needed. HCG at a dose of 5000 IU was administered when at least one mature follicle was observed. β-HCG was measured 2 weeks after HCG administration. Number of mature follicles, endometrial thickness, amount of Gonadotropins consumed, and pregnancy rate were compared between groups.
