BackgroundPolycystic ovarian syndrome (PCOS) is one of the most common endocrinopathies among reproductive-age women. Its metabolic features often overlap with those associated with metabolic syndrome (MS) and insulin resistance syndrome (IRS). The objective of this study was to determine the prevalence and predictors of MS and IRS in infertile Vietnamese women with PCOS.MethodsA cross-sectional study was conducted at a tertiary fertility centre at Hue University Hospital from June 2016 to November 2017. A total of 441 infertile women diagnosed with PCOS based on the revised 2003 Rotterdam consensus criteria were enrolled. MS and IRS were defined based on the National Heart, Lung, and Blood Institute/American Heart Association Adult Treatment Panel III 2005 and American College of Endocrinology IRS 2003 criteria, respectively. Complete clinical and biochemical measurements of 318 women were available for analysis. Independent predictors of MS and IRS were identified using multivariate logistic regression.ResultsThe overall prevalence of MS and IRS in women with PCOS was 10.4% and 27.0%, respectively. We identified older age (>30 years) and obesity as independent predictors of MS and IRS. Elevated anti-Müllerian hormone levels increased the risk of IRS, but not that of MS.ConclusionMS and IRS are prevalent disorders among infertile Vietnamese women with PCOS. PCOS is not solely a reproductive problem. Screening and early intervention for MS and/or IRS based on anthropometric, metabolic, and reproductive hormone risk factors should be an integral part of fertility care.
This study is aimed at comparing clinical pregnancy rates (CPRs) in patients who are administered either gonadotropin-releasing hormone agonist (GnRHa) or human chorionic gonadotropin (hCG) for ovulation trigger in intrauterine insemination (IUI) cycles. A prospective randomized comparative study was conducted at Hue University Hospital in Vietnam. A total of 197 infertile women were randomly assigned to receive either GnRHa trigger (n=98 cycles) or hCG trigger (n=99 cycles) for ovulation trigger. Patients returned for ultrasound monitoring 24 hours after IUI to confirm ovulation. A clinical pregnancy was defined as the presence of gestational sac with fetal cardiac activity. There was no difference in ovulation rates in either group receiving GnRHa or hCG trigger for ovulation. Biochemical and CPR were higher in patients who received hCG (28.3% and 23.2%) versus GnRHa (14.3% and 13.3%) (p=0.023, OR 0.42, 95%CI=0.21−0.86 and p=0.096, OR 0.51, 95%CI=0.24−1.07, respectively). After adjusting for body mass index (BMI) and infertility duration, there was no difference in CPR between the two groups (OR 0.58, 95% CI 0.27-1.25, p=0.163). In conclusion, the use of the GnRHa to trigger ovulation in patients undergoing ovulation induction may be considered in patients treated with IUI.
Introduction: The Female Sexual Function Index (FSFI) is regarded as a self-administered screening questionnaire for assessing the presence of any type of sexual dysfunction. Aim: The aim of this study was to investigate the psychometric properties of the Vietnamese translation version of the Female Sexual Function Index (VN-FSFI) in a sample of infertile Vietnamese women. Methods: An existing Vietnamese translated-FSFI version was used as a first-step approach to back-translate into English. Based on the comparison of the original English version and the back-translation script, a modified version of the FSFI was revised. This version was evaluated for "content validity" by a panel of 3 experts and for "face validity" by a pilot study that was based on its results to refine to reach the last Vietnamese FSFI version (VN-FSFI version). A cross-sectional survey to investigate psychometric reliability and validity of the last VN-FSFI version was conducted with 271 infertile Vietnamese women from January 2017 through February 2018, at a hospital located in a central region of Vietnam. Construct validity was evaluated by principal component analysis using varimax rotation and factor analysis. Reliability studies on internal consistency (Cronbach's alpha coefficient, domain inter-correlations, and domain-total correlations) and on test-retest (Intraclass correlation coefficient). Main Outcome Measure: Construct validity and the reliability of the VN-FSFI version.Results: Based on principal component analysis, a 5-factor model was established, consisting of arousal/ orgasm, satisfaction, pain, lubrication, and desire that explained 72.32% of the total variance. The factorial structure supported to 6 retrieved domains that corresponded to the original version. The Cronbach's alpha coefficients were 0.92 for the total scale and 0.72À0.89 for the domains. Domain inter-correlations ranged from 0.36À0.73 and domain-total correlation coefficients ranged from 0.67À0.84. Test-retest correlation coefficients over 2À4 weeks were 0.97 (P < .001) for the total scale and 0.84À0.96 for the domains. Conclusion: With good psychometric properties, which are almost similar to the original English version, this Vietnamese translation version of the Female Sexual Function Index (VN-FSFI version) was proved to be a valid and reliable instrument to measure multidimensional aspects of sexual function in infertile Vietnamese women.
