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 ...

Embryo culture in presence of oviductal fluid induces DNA methylation changes in bovine blastocysts [PDF]
, 2017 During the transit through the oviduct, the early embryo initiates an extensive DNA methylation reprogramming of its genome. Given that these epigenetic modifications are susceptible to environmental factors, components present in the oviductal milieu ...

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).

The Effect of Prolonged Culture of Chromosomally Abnormal Human Embryos on The Rate of Diploid Cells [PDF]
International Journal of Fertility and Sterility, 2016 Background A decrease in aneuploidy rate following a prolonged co-culture of human blastocysts has been reported. As co-culture is not routinely used in assisted reproductive technology, the present study aimed to evaluate the effect of the prolonged ...
