    Abstract: 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 0.72−0.89 for the domains. Domain inter-correlations ranged from 0.36−0.73 and domain-total correlation coefficients ranged from 0.67−0.84. Test-retest correlation coefficients over 2−4 weeks were 0.97 (P & lt; .001) for the total scale and 0.84−0.96 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.

    Abstract: Objectives: The frequency of, and relationship between, the various manifestations of male sexual dysfunction in infertile couples have been poorly investigated, especially in Vietnam. Our study aims to assess the prevalence of premature ejaculation and erectile dysfunction in infertile couples using validated instruments, and the relationship between these disorders. Method: Cross-sectional descriptive study, using validated questionnaires including the Premature Ejaculation Diagnostic Tool (PEDT) and the International Index of Erectile Function-15 (IIEF-15), to measure the incidence of these problems in 255 male partners of infertile couples who were examined from January through December 2017, at the Center for Reproductive Endocrinology & Infertility, Hue University Hospital. Results: The prevalence of overt premature ejaculation was 4.7%, probable premature ejaculation was 7.1%, and erectile dysfunction was 26.3% (mild: 19.3%, mild-to-moderate: 3.9%, moderate: 2.7%, and severe: 0.4%). The PEDT total score was negatively correlated to IIEF-15-EFD and IIEF-15 total scores (r [Formula: see text]0.322 and r [Formula: see text] 0.348, respectively). Conclusions:In light of the identified prevalence of premature ejaculation and erectile dysfunction in the studied population, screening for these conditions should be included in the evaluation of infertile couples. These two disorders could negatively reciprocal effect on each other.

    Abstract: This study aimed to investigate the association between sperm quality assessed by routine semen analysis and sperm DNA integrity assay. Methods In our cross‐sectional study, a total of 318 men from the infertile couples were enrolled from December 2017 to March 2019 at the Hue Center for Reproductive Endocrinology and Infertility, Vietnam. General characteristics and semen parameters were detected. The sperm DNA fragmentation index (DFI) was estimated by the sperm chromatin dispersion (SCD) assay. A threshold of DFI 30% was applied to classify normal (DFI  〈  30%) or abnormal (DFI ≥ 30%) groups. The correlations between DFI and semen parameters were analyzed by Spearman's rank correlation coefficient. Results In the correlation analysis, DFI was significantly correlated with abnormal head and progressive motility, with a positive correlation with abnormal head ( ρ  = .202, P  = .0003) and a weak negative correlation with progressive motility ( ρ  = −.168, P  = .0027), respectively. In the bivariate analysis, DFI was associated with male age, smoking, and alcohol consumption with P   〈  .05. Conclusions The sperm DFI was not strongly correlated with conventional semen parameters. Therefore, a sperm DNA fragmentation assay should be performed as an additional step in the investigation of male fertility.

    In: Journal of International Medical Research, SAGE Publications, Vol. 50, No. 5 ( 2022-05), p. 030006052210974-
    Abstract: This study was performed to determine the effect of swim-up (SU) and density gradient centrifugation (DGC) on sperm survival and DNA fragmentation. Methods Individual semen samples were analyzed before each was divided into two aliquots (half for SU and half for DGC) for calculation of sperm survival and the DNA fragmentation index (DFI). Sperm DNA fragmentation was determined using the sperm chromatin dispersion test. Results The DFI of the 63 semen samples processed using both procedures was lower than that of the fresh semen samples. The DFI was significantly lower for samples processed using the SU than DGC method. In the sperm survival test, the SU technique was associated with increased sperm motility and vitality following preparation. After 24 hours, however, the concentration and percentage of surviving sperm were significantly lower in the SU than DGC group. Conclusions Both semen preparation techniques help to minimize sperm DNA fragmentation; however, when the DFI is 〈 30%, the SU technique is more appropriate than DGC. While DGC may be superior for intrauterine insemination, the SU method may be preferable for in vitro fertilization or maturation.

    Abstract: This study explores the role of anti‐Mullerian hormone (AMH) and LH/FSH ratio in diagnosis of polycystic ovary syndrome (PCOS). Methods In this multicentre cross‐sectional descriptive study, a total of 863 infertile women between 18 and 45 years were evaluated at three infertility centres in Vietnam and were recruited from June 2016 to June 2017. The patients were classified into two groups: Group I included 441 patients with PCOS (based on Rotterdam criteria consensus) and Group II included 422 non‐PCOS women. Diagnosis of PCOS was established based on Rotterdam 2003 consensus, and exclusion criteria were ovarian disease (ovary cyst/tumour), history of ovarian surgery and ovarian failure. Results At an optimum cut‐off level of 32.79 pmol/L, AMH showed sensitivity and specificity of 78.50% and 75.83%, respectively, with the AUC 0.852 (95% CI: 0.826‐0.875). The LH/FSH ratio had a similar AUC at the optimum cut‐off of 1.33 (AUC = 0.867, 95% CI 0.842‐0.889), which demonstrated a similar diagnosis value to AMH ( P  = 0.340). By using multiple logistic regression analysis, 1 ng/mL increase in AMH levels was associated with an increased risk of PCOS (OR = 1.63, 95% CI: 1.506‐1.764; P   〈  0.001). Similarly, one unit increase in LH/FSH ratio was associated with 14.433 times increased (95% CI: 9.302‐22.395; P   〈  0.001) risk of PCOS. There were no significant differences between values of AMH and LH/FSH ratio in PCOS diagnosis, as the difference between the two AUCs was 0.013, 95% CI: −0.024 to 0.028 and P  = 0.897. Conclusion The value of serum AMH concentration has been found not significantly superior to LH/FSH ratio in PCOS diagnosis. Although these biomarkers separately are not adequate for PCOS diagnosis based on their own value, the combination of different endocrine factors including AMH, LH and LH/FSH ratio together with BMI and other anthropometric and clinical characteristics may offer extra value to establish the diagnosis of PCOS.

    In: International Journal of Endocrinology, Hindawi Limited, Vol. 2019 ( 2019-03-13), p. 1-6
    Abstract: 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.
