Semnan, Iran three Division of obestertics gynecology, Semnan University of Healthcare Sciences, Semnan, IranReceived February 2013; Revised accepted March yAbstractObjective: The aim of this study would be to ascertain if simvastatin pretreatment would modify clomiphene response in clomiphene citrate-resistant (CC-R)girls with (PCOS). Components and techniques: This quasi experimental study integrated twenty five clomiphene resistant girls with PCOS. All patients received cyclic oral contraceptives pills (OCP) (30 of ethinyl estradiol and 150 of desogestrol) from the 5th day of their spontaneous or progesterone (P) induced menstrual cycle; furthermore, they received simvastatin (20mg/day) from the first day of cycle for two consecutive months. Then, individuals were provided 100 mg clomiphene citrate (CC) (Iran Hormone, Iran) for five days beginning from day three of their menstrual cycles. The primary outcome measures have been ovulation and pregnancy prices. The modify in physique mass index (BMI), the mean number of follicles 18 mm, the imply of follicular size and endometrial thickness around the day of human chorionic gonadotropin (HCG) administration have been secondary outcome measures. Results: Ovulation occurred in 5 out of 25 (20 ) patients, but none of your patients conceived in this study. No crucial alter in BMI was observed after applying simvastatin (0.28+1.13; p=0.228). In all sufferers with ovulation, the number of follicles 18mm was one particular. The imply follicular size and endometrial thickness around the day of HCG administration had been 19.67 ?2.04 and 7.00 ?1.34, respectively. Conclusion: Within this study, we didn’t observe the favorable impact on ovulation and pregnancy rates with CC following of simvastatin pretreatment in CC-resistant PCOS ladies. So, additional studies with a larger number of individuals, larger doses of CC and more cycles are essential to make this clear.
