Comparative Embryo Development Outcomes following Extending Embryo Culture to Day 6: A Retrospective Cohort Study [PDF]
International Journal of Fertility and Sterility, 2023 Background: Past studies have shown that culturing slow-growing embryos from day 5 to day 6 may increase vitrification yield. This study aims to evaluate if the proportion of embryos eligible for vitrification increases by growing embryos not vitrified ...

Hyaluronan and Hyaluronidase, which is better for embryo development? [PDF]
, 2016 Our aim was to examine size-specific effects of Hyaluronan (HA) on preimplantation embryo development. We investigated the effects of Hyalovet (HA, 500–750 kDa; the size produced by HA synthase-3, which is abundant in the oviduct), or HA treated with ...

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]
, 2020 In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.

Correlated response in early embryonic development in rabbits selected for litter size variability
World Rabbit Science, 2017 A divergent selection experiment for litter size variability was carried out in rabbits. The litter size variability was estimated as the phenotypic variance of litter size within female.

Frozen blastocysts: Assessing the importance of day 5/day 6 blastocysts or blastocyst quality
Experimental and Therapeutic Medicine, 2022 The aim of the present study was to analyze the high-quality blastocyst (HB) rate in all embryo frozen cycles and investigate the pregnancy outcomes for day 5/day 6 (D5/D6) blastocysts with respect to the blastocyst quality in programmed single vitrified-warmed blastocyst transfer (SVBT).

Repeats as global DNA methylation marker in bovine preimplantation embryos [PDF]
, 2017 DNA methylation undergoes dynamic changes and is a crucial part of the epigenetic regulation during mammalian early development. To determine the DNA methylation levels in bovine embryos, we applied a bisulfite sequencing based method aimed at repetitive

microRNAs as A Biomarker to Predict Embryo Quality Assessment in In Vitro Fertilization [PDF]
International Journal of Fertility and Sterility, 2023 Embryo selection for in vitro fertilization (IVF) is an effort to increase the success rate of embryo implantation. Factors influencing the success of embryo implantation include embryo quality, endometrial receptivity, embryo characteristics, and ...
