Background and Objective: There is a genetic background for polycystic ovary syndrome (PCOS). Due to increase metabolic disorders, lipoproteins, impaired glucose tolerance, and hypertension in PCOS patients, this study was done to determine the cardiovascular risk factors in first relative member of patients with polycystic ovarian syndrom in Shiraz, Iran. Materials and Methods: This case - control study was carried out on 107 parents and siblings of women with PCOS as cases and 107 non-PCOS parents and siblings of women as controls in Shiraz, Iran during 2007-08. Demographic characteristic, BMI, obesity and blood pressure were recorded for all subjects. Serum lipoproteins including total cholestrol, triglyceride, LDL, HDL and fasting blood sugar were measured in cases and controls. Data were analyzed using SPSS-16.5, independent t-test, Chi-Square and Kappa tests. Results: 35.3%, 26.5%, 11.76% and 5.8% of fatheres in cases were considered as overweight class I, class II, class III of obesity, respectively when compared to controls. This differecne was significant (P<0.05). Waist –hip ratio in mothers in cases (25.6%) and controls (17.9%) were higher than 0.85. Waist –hip ratio among the sisters in case and control groups were 23.5% and 17.6%, respectively (P<0.05). Hypertension was observed in 12.2% of cases and 3.7% of controls. This difference was not significant. High level of triglyceride were determined in 14.94% of cases and 6.5% of controls. A significant correlation was found between BMI and diabete II in case and control groups (P<0.05). Disorder in glucose tolerance test (GTT) in case and control goups were 19.62% and 7.47%, respectively (P<0.05). The obesity was found in 18.7%, 6.54% in cases and controls with disorder in GTT (P<0.05). Conclusion: This study showed that obesity, central obesity, high level of serum lipoproteins and hypertension among first relative member of patients with PCOS are significantly higher than the controls.

Background and Objective: Polycystic ovary syndrome (PCOS) is the most endocrine disorder in women. This study was done to determine the effect of N-acetylcysteine with letrozole to induction of ovulation in infertile women with polycystic ovarian syndrome.

Methods: This clinical trail study was carried out on forty PCOS women with normal TSH, prolactin, hysterosalpingographies and normal spermograms. The patients in control group were received letrozole 5 mg/d for 5 days starting at day 3 of the cycle. The patients in interventional group were received letrozole 5 mg/d with NAC 1.2 g/d (group II) for 5 days starting at day 3 of the cycle. On 14^th day of cycle, transvaginal ultrasonography was performed to evaluate endometrial thickness and follicles properties. If mature follicle detected, hCG was injected and timed coitus at 12, 36 and 60 hours later advised. β-hCG level was checked on day 16 after hCG injection.

Results: The mean of endometrial thickness and follicles ovulation in hCG injection day was similar in the two groups. The pregnancy rate was 15% and 20% in control and interventional groups, respectively. This difference was not significant. The mean of follicles number was 1.13% and 1.47% in control and interventional groups, respectively. This difference was not significant.

Conclusion: NAC as an adjuvant to letrozole was not effective for ovulation induction in patients with PCOS.

Background and Objective: Polycystic Ovarian Syndrome (PCOS) is considered as a metabolic disorder and it is one of the most common endocrine and heterogeneous disorders with complex pathogenesis among women in reproductive ages. This study was done to evaluate the accuracy of diagnosis of lipid accumulate product index (LAP), insulin resistance, waist circumference and waist to hip ratio in women with polycystic ovary syndrome.
Methods: In this case control study, antropometrics, biochemical parameters, LAP and insulin resistance in 43 women suffering from PCOS as case and 40 healthy women as control were measured. Body mass index (BMI), waist hip ratio (WHR) and waist circumference (WC) was determined for each subject. LAP was defined as [WC (cm)-58´TG (m mol/L)]. PCOS was diagnosed according to Roterdam standard .Insulin resistance was defined based on Homeostatic model assessment – insulin resistance (HOMA-IR).
Results: The mean age, BMI, WHR and LAP index, among PCOS women were 24.06±5.86, 26.61±4.34, 0.81±0.061 and 47.13±4.13, respectively. There was a direct and significant correlation between HOMA-IR index and BMI, WC and LAP in case group (P<0.05). Statistical analysis showed that the optimal cut-off value of LAP, BMI, WC and WHR were 46.93, 27.91, 93 and 0.81 respectively.
Conclusion: The WC, BMI and LAP indices are useful in screening the insulin resistance in patients with PCOS.
