Abstract: This study aims to know what proportion of culture day 5 pre-blastocyst-stage embryos develop into blastocysts by culture day 6 and what patient and cycle characteristics are associated with delayed blastocyst formation. A retrospective observational… read more here.

Abstract: OBJECTIVE: In mammals, the oxygen (O2) tension in the uterus is lower (2%) than the oviduct (5-7%). This fits with a shift in the metabolic strategy of the embryo after compaction and may have implications… read more here.

DOI: 10.1016/j.rbmo.2019.07.007
Abstract: Objective Recent data demonstrate higher aneuploidy rates in day 7 embryos. It is unknown if increased aneuploidy rates are limited to specific embryos with slower development or if the presence of slower development indicates higher… read more here.

DOI: 10.1093/humrep/deab130.525
Abstract: May the mosaicism ratio be influenced by the time of blastulation in preimplantation genetic testing for aneuploidies (PGT-A)? The mosaicism ratio is significantly higher in day–6 blastocysts when compared to day–5 when transferable embryos are… read more here.
