    Abstract: Une association directe entre le syndrome métabolique (MetS) et la production/fonction des spermatozoïdes a été proposée. Dans cette étude transversale, nous avons cherché à déterminer l’impact du MetS sur le taux de survie des spermatozoïdes (TSS). Des hommes issus de couples inféconds traités à l’hôpital universitaire de Hue, au Vietnam, ont été inclus dans cette étude qui s’est. étendue sur la période d’octobre 2018 à octobre 2020. Les caractéristiques générales des patients, y compris l’indice de masse corporelle (IMC), le rapport taille-hanche, les niveaux de différents paramètres biochimiques et les paramètres de sperme ont été déterminés, ainsi que les taux de survie des spermatozoïdes (TSS). Le panel modifié du traitement des adultes (ATP III) du Programme National d’Education sur le Cholestérol (NCEP) pour la population asiatique a été utilisé pour le diagnostic de MetS. Résultats Les hommes avec un tour de taille anormal (≥ 90 cm) ont montré un taux plus élevé de résultats anormaux de SST (30,1% versus 16,7%, p  = 0,012). La fréquence de résultats anormaux de TSS chez les patients avec MetS (72.3%) était significativement plus élevée que celle des individus sans MetS (53,4%) ( p  = 0,02). En outre, le pourcentage de résultats anormaux de TSS chez les patients avec MetS et avec un BMI ≥ 23 était significativement plus élevé que celui des individus sans MetS (77,1% versus 55,2%, p  = 0,03). On a également observé de faibles corrélations négatives entre l’âge des patients et les résultats du TSS. Conclusion La viabilité des spermatozoïdes était plus faible chez les hommes atteints de MetS. Nous avons également observé que l’âge et l’IMC étaient des facteurs indépendants associés à un TSS anormal.

    Abstract: Objective: As the associations of sperm DNA fragmentation with morphology have not been examined in detail, this study aimed to investigate the relationship between abnormalities of morphological details and DNA integrity in human sperm.Methods: In this cross-sectional study, men from infertile couples were enrolled at Hue Center for Reproductive Endocrinology and Infertility, Vietnam. Conventional semen parameters, including morphological details, were analyzed following the World Health Organization 2010 criteria. Sperm DNA fragmentation was evaluated using a sperm chromatin dispersion assay. The relationships and correlations between semen parameters, sperm morphology, and the type of halosperm and the DNA fragmentation index (DFI) were analyzed.Results: Among 130 men in infertile couples, statistically significant differences were not found in the sperm halo type between the normal and abnormal sperm morphology groups. The percentage of round-head spermatozoa was higher in the DFI 〉 15% group (16.98%±12.50%) than in the DFI ≤15% group (13.13%±8.82%), higher values for amorphous heads were found in the DFI 〉 15% group, and lower values for tapered heads were observed in the DFI ≤15% group; however, these differences were not statistically significant. Small-halo sperm and the DFI were positively correlated with round-head sperm (r=0.243, p=0.005 and r=0.197, p=0.025, respectively). Conclusion: The rate of general sperm morphological abnormalities in semen analysis was not related to sperm DNA integrity. However, round sperm heads were closely associated with sperm DNA fragmentation.

    Abstract: Objective: This study aimed to compare the efficacy of physiological intracytoplasmic sperm injection (PICSI) and intracytoplasmic sperm injection (ICSI) in terms of the fertilization rate and embryo quality using sibling oocyte cycles.Methods: This prospective, cross-sectional study collected data from 76 couples who underwent their first cycle at the Hue Center for Reproductive Endocrinology and Infertility, Vietnam, between May 2019 and November 2021. The inclusion criteria were cycles with at least eight oocytes and a sperm concentration of 5×106/mL. Sperm parameters, sperm DNA fragmentation (SDF), fertilization, and the quality of cleavage-stage embryos on day 2 and blastocysts on day 5 were examined.Results: From 76 ICSI cycles, 1,196 metaphase II (MII) oocytes were retrieved, half of which were randomly allocated to either the PICSI (n=592) or ICSI (n=604) treatment group. The results showed no significant difference between the two groups in terms of fertilization (72.80% vs. 75.33%, p=0.32), day 2 cleavage rate (95.13% vs. 96.04%, p=0.51), blastulation rate (52.68% vs. 57.89%), and high-quality blastocyst rate (26.10% vs. 31.13%, p=0.13). However, in cases where SDF was low, 59 cycles consisting of 913 MII oocytes produced a considerably higher blastulation rate with PICSI than with ICSI (50.49% vs. 35.65%, p=0.00). There were no significant differences between the pregnancy outcomes of the PICSI and ICSI embryo groups following embryo transfer.Conclusion: Using variable sperm quality provided no benefit for PICSI versus ICSI in terms of embryo outcomes. When SDF is low, PICSI appears to be able to produce more blastocysts.

    Abstract: This study aimed to determine the relationship between oxidative stress (OS) measured by the oxidation–reduction potential (ORP) and the results of semen analysis among men from infertile couples. Methods This cross-sectional study included 166 men from infertile couples, determined according to the World Health Organization guidelines. The general characteristics, semen analysis, sperm chromatin dispersion assay, and ORP of all subjects were evaluated and analyzed statistically. Results Among 166 men from infertile couples, individuals with OS had a significantly higher DNA fragmentation index (DFI) than men without OS (22.37% ± 11.67% vs. 17.98% ± 8.98%). The sperm concentration, total sperm count, motility rate, and normal morphology were negatively correlated, while and an abnormal head and neck–tail were positively correlated with ORP. There was also a positive association between the DFI and OS level. The optimal ORP threshold for determining sperm quality was 0.77 mV/10 6 sperm/mL (sensitivity, 50.4%; specificity, 93.5%; positive predictive value, 52.9%; negative predictive value, 32.3%). Conclusions Determining the ORP suggests that OS has an adverse effect on the total sperm count, sperm motility, sperm concentration, morphology, vitality, and DNA fragmentation index.

    Abstract: Introduction: This study aimed to determine the incidence of lower genital infections and related factors in preterm premature rupture of membranes (PPROM) and preterm labor. Methodology: A case-control study was conducted on pregnant women who were admitted to the Hospital of Hue University of Medicine and Pharmacy, Vietnam between November 2017 and May 2019. Cases from 22 to 36 gestational weeks were included as group 1 (patients with preterm labor and intact membranes) or as group 2 (those with PPROM). The control group included women with singleton pregnancies who were matched on gestational age and recruited concurrently with the study cases. Gram stain was perfomed to identify Lactobacillus, Gardnerella, mobiluncus, Candida, and leucocytes. Trichomonas vaginalis was detected by wet mount. Cultures of vaginal secretions and aminotic fluid were performed to identify aerobic bacteria. Results: Bacterial vaginosis was higher in group 1 (28.9%) compared to control (11.4%). The incidence of isolated aerobic bacteria was 44.1% in group 2, 11.1% in group 1, and 12.7% in the control group (p 〈 0.001). Fungal infection was not shown to be a risk factor for preterm labor (p = 0.990), whereas, bacterial vaginosis was (OR = 3.16; 95%CI = 1.23-8.15; p = 0.016). Isolated aerobic bacteria were associated with premature rupture of membranes (OR = 5.45; 95%CI = 2.11-14.05; p 〈 0.001). Conclusions: Bacteria vaginosis increased the risk of preterm labor and preterm premature rupture of membranes. Isolated aerobic bacteria were related to PPROM, while fungal infection was not associated with preterm labor.

    Abstract: La spermatogenèse et la qualité du sperme peuvent être affectées négativement par une augmentation des espèces réactives de l'oxygène. La présente étude évalue l'efficacité d’une thérapie antioxydante combinée pour traiter l'infertilité masculine, telle que mesurée par les analyses du sperme et l'indice de fragmentation de l'ADN des spermatozoïdes (DFI). Les hommes infertiles avec un indice de fragmentation de l'ADN des spermatozoïdes élevé ont été invités à prendre, par voie orale, deux capsules de micronutriments par jour pendant trois mois. Chaque formulation antioxydante contenait 60 mg de vitamine E, 400 μg d'acide folique, 30 mg de sélénium, 125 mg de L-arginine, 220 mg de L-carnitine, 7,5 mg de coenzyme Q10, 40 mg de L-glutathion et 20 mg de citrate de zinc. À l'entrée et après le traitement, les caractéristiques générales, l'analyse du sperme et les tests de dispersion de la chromatine spermatique ont été enregistrés et comparés. Résultats Après trois mois de traitement avec des composés antioxydants, la qualité des spermatozoïdes s'est considérablement améliorée, comme l'indique une diminution de l'indice moyen de fragmentation de l'ADN de 45,6±17,2% à 34,8±20,3%; une augmentation de la concentration de spermatozoïdes de 29,7×106/mL à 35,7×106/mL ( p 〈 0,001), une augmentation du nombre total de spermatozoïdes de 72,1x106 à 95,5x106 ( p =0,012), et une augmentation de la vitalité de 75,5±17,1 à 81,1±14,4% des formes viables ( p 〈 0,001). Conclusions La supplémentation en micronutriments peut améliorer la qualité du sperme et l'intégrité de l'ADN chez les hommes infertiles. Les hommes souffrant d'infertilité et d'une fragmentation importante de l'ADN des spermatozoïdes qui prennent des antioxydants pendant trois mois subissent une réduction de l'indice de fragmentation de l'ADN et une augmentation de la qualité du sperme, mesurée par l'analyse du sperme.
