Background: Vitrification is a recently introduced yet widely applied assisted reproduction technique. So far, the effects of the chemicals and devices in vitrification on sperm motility and DNA integrity are still unclear.
Objective: This study aimed to examine sperm quality, as determined by semen analysis and sperm DNA integrity when vitrified with or without cryoprotectant agents (CPAs) using pulled-glass capillaries.
Objectives: 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.
Article Synopsis
- - The study compared physiological intracytoplasmic sperm injection (PICSI) and regular intracytoplasmic sperm injection (ICSI) in terms of fertilization rates and the quality of embryos using sibling oocytes from 76 couples undergoing their first cycle at a reproductive center in Vietnam.
- - Both methods showed similar fertilization rates and embryo quality overall, but PICSI significantly improved the blastulation rate in cases with low sperm DNA fragmentation compared to ICSI.
- - The findings suggest that while there is no overall benefit of PICSI over ICSI for embryo outcomes when sperm quality is variable, PICSI does yield better results in blastocyst formation under low DNA fragmentation conditions.
Objective: 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.
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.
Background: A direct association between metabolic syndrome (MetS) and sperm production/function has been proposed. In this cross-sectional study, we aimed to determine the impact of MetS on sperm survival. Men from infertile couples treated at Hue University Hospital, Vietnam, were enrolled in this study, which spanned the October 2018 to October 2020 period.

Women who had previously failed in the cleavage-stage embryo transfer, underwent extended culture of their warmed cleavage embryos to the blastocyst stage, thereby improving cryopreserved embryo transfer (CET) outcomes, although the ability of embryos to reach the extended blastocyst as well as the value of the prolonged culture was limited. This study aimed to investigate the effectiveness of blastocyst transfer by extending the culture of vitrified-warmed cleavage embryos.
