Brief Summary
The use of GnRH antagonist protocol nowadays is the slandered protocol of controlled ovarian stimulation in patients with poly cystic ovarian syndrome (PCOS) because it decreases the incidence of OHSS(1, 2). However, this protocol may lead to asynchronous growth of follicles with an early dominant follicle specially in PCOS patients(3). In most of cases this phenomenon will affect the IVF outcomes(2, 4) Aromatase inhibitors (AIs) nowadays is recommended to be used for ovulation induction in patients with PCOS (5, 6).It has fewer side effects, and a shorter half-life than clomiphene citrate(CC), and no effect ON the endometrial receptivity. It is used in treating patients with chronic anovulation, unexplained infertility and poor ovarian reserve(7). It acts through decreasing estrogen levels and allows follicle stimulating hormone (FSH) release from the hypothalamus (8, 9). It could be used alone or with combination with human menopausal gonadotropin (HMG) specially in patients with CC resistant(10-13). It also improves the ovarian response to FSH when they are used in combination and it decreases the risk of OHSS (14). This study aims to evaluate the effect of uses of letrozole in combination with HMG during ovarian stimulation in patients having PCOS undergoing IVF/ICSI on the follicular growth pattern, synchronized growth of follicles, maturity of oocyte and the quality of embryos.

Outcome Measures
Primary Outcomes (1)
the number of asynchronized follicles in both groups
• Asynchronization will considered when there is a difference of at least 2 mm between the dominant follicle and other follicles
30 min
Study Arms (2)
• Study group
ACTIVE COMPARATORIt contains 100 patients will undergo ovarian stimulation with letrozole 2.5mg twice daily (Femara; Novartis Pharma Services, Basel, Switzerland) for 5 days starting from the first day of menstruation in combination with low dose step up stimulation with recombinant FSH starting in the third day of menstruation.
• Control group
NO INTERVENTIONIt contains 100 patients will undergo ovarian stimulation with low dose step up stimulation with recombinant FSH starting in the third day of menstruation
