    Background: Tubal occlusion is one of the most frequent causes of infertility in women. The evaluation of the fallopian tube is necessary to determine the management plan for infertility. The two most important diagnostic procedures which are used for the evaluation of tubal patency are hysterosalpingography (HSG) and laparoscopy. Objectives: The aim of this study was to compare HSG and laparoscopic findings in the diagnosis of tubal patency. Patients and Methods: In a prospective study sixty two infertile cases were examined by HSG as part of their routine infertility evaluation, three months after HSG, tubs status were assessed by laparoscopy as a gold standard method. The findings of HSG and laparoscopy were compared. The Laparoscopy findings were used as reference standard to calculate sensitivity, specificity, positive and negative predictive values for unilateral and bilateral no tubal patency. Results: The sensitivity and specificity of HSG on bilateral tubal patency or no bilateral tubal patency were 92.1% and 85.7% respectively. The positive and negative predictive values were 97.2% and 66.7%, and the accuracy was 91.1%. The sensitivity and specificity of HSG for evaluation of the bilateral tubal patency and unilateral or bilateral no tubal patency were 77.8% and 52.94%, the positive and negative predictive values were 81.4% and 47.4% respectively, and the accuracy was 71%. Conclusion: HSG is considered to have a high sensitivity and specificity. HSG and laparoscopy are not alternative, but are the complementary methods in the examination of no tubal patency

    The aim of this study was to compare pregnancy, childbirth, and neonatal outcomes in women with different phenotypes of polycystic ovary syndrome (PCOS) with healthy women. A prospective cohort study from the beginning to the end of pregnancy for 41 pregnant women with PCOS (case) and 49 healthy pregnant women (control) was completed. Based on the presence or absence of menstrual dysfunction (M), hyperandrogenism (HA), and polycystic ovaries (PCO) on ultrasound, the PCOS (case) group were divided into three phenotypes (HA + PCO (  = 22), M + PCO (  = 9), HA + M+PCO (  = 10). Pre-eclampsia, gestational diabetes, and lower birth weight among newborns were significantly higher in the PCOS case group compared to the control group especially in the phenotype HA + M+PCO (  < .05). High BMI (  = 2.40; =.03) was the strongest predictor of pre-eclampsia in patients with PCOS. High androgen levels (free androgen index) (  = 13.71, 3.02;  < .05), was the strongest predictor of developing diabetes during pregnancy and reduced birth weight baby, respectively.These results suggest that PCOS, particularly in phenotype HA + M+PCO (  < .05), is a risk factor for adverse pregnancy and neonatal outcomes including gestational diabetes, pre-eclampsia, and reduced weight babies

    Objective: The aim of this study was to evaluate the effect of curcumin on body weight, glycemic control and serum lipids in women suffering from polycystic ovary syndrome (PCOS). Methods: The current randomized, double-blinded, placebo-controlled clinical trial was performed on 60 subjects with PCOS, aged 18�40 years old. Subjects were randomly allocated to take 500 mg/day curcumin (n = 30) or placebo (n = 30) for 12 weeks. Glycemic control and serum lipids were measured at baseline and after the 12-week intervention. Using RT-PCR method, gene expression related to insulin and lipid metabolism was evaluated. Results: Curcumin significantly decreased weight (�0.8 ± 0.9 vs. �0.2 ± 0.8 kg, P = 0.03) and BMI (�0.3 ± 0.4 vs. �0.1 ± 0.3 kg/m2, P = 0.03). Curcumin, compared with the placebo, significantly reduced fasting glucose (β �2.63 mg/dL; 95 CI, �4.21, �1.05; P = 0.002), serum insulin (β �1.16 μIU/mL; 95 CI, �2.12, �0.19; P = 0.02), insulin resistance (β �0.26; 95 CI, �0.48, �0.03; P = 0.02), and significantly increased insulin sensitivity (β 0.006; 95 CI, 0.001, 0.01; P = 0.02). In addition, taking curcumin was associated with a significant reduction in total cholesterol (β �15.86 mg/dL; 95 CI, �24.48, �7.24; P = 0.001), LDL-cholesterol (β �16.09 mg/dL; 95 CI, �25.11, �7.06; P = 0.001) and total-/HDL-cholesterol ratio (β �0.62; 95 CI, �0.93, �0.30; P &lt; 0.001), and a significant increase in HDL-cholesterol levels (β 2.14 mg/dL; 95 CI, 0.36, 3.92; P = 0.01) compared with the placebo. Additionally, curcumin administration up-regulated gene expression of peroxisome proliferator-activated receptor gamma (PPAR-γ) (P = 0.03) and low-density lipoprotein receptor (LDLR) (P &lt; 0.001) compared with the placebo. Conclusions: Overall, curcumin administration for 12 weeks to women with PCOS had beneficial effects on body weight, glycemic control, serum lipids except triglycerides and VLDL-cholesterol levels, and gene expression of PPAR-γ and LDLR.

    Abstract This study was conducted to evaluate the effects of selenium supplementation on gene expression related to insulin and lipid in infertile women with polycystic ovary syndrome (PCOS) candidate for in vitro fertilization (IVF). This randomized double-blind, placebo-controlled trial was conducted among 40 infertile women with PCOS candidate for IVF. Subjects were randomly allocated into two groups to intake either 200-μg selenium (n = 20) or placebo (n = 20) per day for 8 weeks. Gene expression levels related to insulin and lipid were quantified in lymphocytes of women with PCOS candidate for IVF with RT-PCR method. Results of RT-PCR demonstrated that after the 8-week intervention, compared with the placebo, selenium supplementation upregulated gene expression of peroxisome proliferator-activated receptor gamma (PPAR-γ) (1.06 ± 0.15-fold increase vs. 0.94 ± 0.18-fold reduction, P = 0.02) and glucose transporter 1 (GLUT-1) (1.07 ± 0.20-fold increase vs. 0.87 ± 0.18-fold reduction, P = 0.003) in lymphocytes of women with PCOS candidate for IVF. In addition, compared with the placebo, selenium supplementation downregulated gene expression of low-density lipoprotein receptor (LDLR) (0.88 ± 0.17-fold reduction vs. 1.05 ± 0.22-fold increase, P = 0.01) in lymphocytes of women with PCOS candidate for IVF. We did not observe any significant effect of selenium supplementation on gene expression levels of lipoprotein(a) [LP(a)] in lymphocytes of women with PCOS candidate for IVF. Overall, selenium supplementation for 8 weeks in lymphocytes of women with infertile PCOS candidate for IVF significantly increased gene expression levels of PPAR-γ and GLUT-1 and significantly decreased gene expression levels of LDLR, but did not affect LP(a).

    The primary aim of our study was to determine the influence of taking chromium plus carnitine on insulin resistance, with a secondary objective of evaluating the influences on lipid profiles and weight loss in overweight subjects with polycystic ovary syndrome (PCOS). In a 12-week randomized, double-blind, placebo-controlled clinical trial, 54 overweight women were randomly assigned to receive either supplements (200 μg/day chromium picolinate plus 1000 mg/day carnitine) or placebo (27/each group). Chromium and carnitine co-supplementation decreased weight (� 3.6 ± 1.8 vs. � 1.0 ± 0.7 kg, P &lt; 0.001), BMI (� 1.3 ± 0.7 vs. � 0.3 ± 0.3 kg/m 2 , P &lt; 0.001), fasting plasma glucose (FPG) (� 5.1 ± 6.0 vs. � 1.1 ± 4.9 mg/dL, P = 0.01), insulin (� 2.0 ± 1.4 vs. � 0.2 ± 1.2 μIU/mL, P &lt; 0.001), insulin resistance (� 0.5 ± 0.4 vs. � 0.04 ± 0.3, P &lt; 0.001), triglycerides (� 18.0 ± 25.2 vs. + 5.5 ± 14.4 mg/dL, P &lt; 0.001), total (� 17.0 ± 20.3 vs. + 3.6 ± 12.0 mg/dL, P &lt; 0.001), and LDL cholesterol (� 13.3 ± 19.2 vs. + 1.4 ± 13.3 mg/dL, P = 0.002), and elevated insulin sensitivity (+ 0.007 ± 0.005 vs. + 0.002 ± 0.005, P &lt; 0.001). In addition, co-supplementation upregulated peroxisome proliferator-activated receptor gamma (P = 0.02) and low-density lipoprotein receptor expression (P = 0.02). Overall, chromium and carnitine co-supplementation for 12 weeks to overweight women with PCOS had beneficial effects on body weight, glycemic control, lipid profiles except HDL cholesterol levels, and gene expression of PPAR-γ and LDLR.

    Objective: The aim of this study was to evaluate the effect of melatonin supplementation on mental health parameters, metabolic and genetic parameters in women suffering from polycystic ovary syndrome (PCOS). Methods: This randomized, double-blinded, placebo-controlled clinical trial was performed on 58 subjects, aged 18�40 years old. Subjects were randomly allocated to take either 10 mg melatonin (2 melatonin capsules, 5 mg each) (n = 29) or placebo (n = 29) once a day 1 h before bedtime for 12 weeks. Glycemic control and lipid profiles were measured at baseline and after the 12-week intervention. Using RT-PCR method, gene expression related to insulin and lipid metabolism was conducted on peripheral blood mononuclear cells (PBMCs) of PCOS women. Results: Melatonin supplementation significantly decreased Pittsburgh Sleep Quality Index (β �2.15; 95 CI, �3.62, �0.68; P = 0.005), Beck Depression Inventory index (β �3.62; 95 CI, �5.53, �1.78; P<0.001) and Beck Anxiety Inventory index (β �1.95; 95 CI, �3.41, �0.48; P = 0.01) compared with the placebo. In addition, melatonin administration, compared with the placebo, significantly reduced serum insulin (β �1.20 µIU/mL; 95 CI, �2.14, �0.26; P = 0.01), homeostasis model of assessment-insulin resistance (HOMA-IR) (β �0.28; 95 CI, �0.50, �0.05; P = 0.01), serum total- (β �7.96 mg/dL; 95 CI, �13.75, �2.17; P = 0.008) and LDL-cholesterol levels (β �5.88 mg/dL; 95 CI, �11.42, �0.33; P = 0.03), and significantly increased the quantitative insulin sensitivity check index (QUICKI) (β 0.008; 95 CI, 0.002, 0.014; P = 0.007). Moreover, melatonin supplementation upregulated gene expression of peroxisome proliferator-activated receptor gamma (PPAR-γ) (P = 0.004) and low-density lipoprotein receptor (LDLR) (P = 0.01) compared with the placebo. Conclusions: Overall, melatonin administration for 12 weeks had beneficial effects on mental health parameters, insulin levels, HOMA-IR, QUICKI, total- and LDL-cholesterol levels, and gene expression of PPAR-γ and LDLR among women with PCOS. © 2019 Elsevier B.V
