Abstract This study aimed to examine the viability of human blastocysts after warming with fatty acids (FAs) using an in vitro outgrowth model and to assess pregnancy outcomes after a single vitrified-warmed blastocyst transfer (SVBT). For the experi

Abstract Background Human embryos express the prolactin (PRL) receptor at the morula and blastocyst stages. Treatment with PRL from cleavage to the blastocyst stage improves blastocyst outgrowth on fibronectin-coated dishes. However, whether post-war

Background and Aims: In recent years, preimplantation genetic testing (PGT) has frequently involved a trophectoderm (TE) biopsy at the blastocyst stage, followed by vitrification. However, the factors influencing the viability of biopsied blastocysts

Background and Aims: With the exception of chromosome segregation errors, the molecular and biochemical mechanisms responsible for advanced maternal age (AMA)-related reduced embryo developmental competence remain unclear. In women of AMA, the blasto

Background and Aims: The vitrification procedure decreased intracellular lipid content and subsequent developmental competence. Furthermore, a recent study reported that fatty acid (FA) supplementation into warming solutions increased intracellular l

Abstract Purpose This study aimed to examine the embryonic development of human 4‐cell stage embryos after warming with fatty acids (FAs) and to assess the pregnancy outcomes after single vitrified‐warmed cleavage stage embryo transfers (SVCTs).

Abstract Background Information regarding the influence of cytoplasmic events during fertilisation on the clinical outcome remains limited. The cytoplasmic halo is one of these events. A previous study that used time-lapse technology found an associa

Abstract Purpose The present study aimed to examine the correlations of the time interval from trophectoderm (TE) biopsy to vitrification with the blastocyst survival rate and blastocyst outgrowth ability. Methods A total of 1,202 mouse blastocysts w

Abstract Background Blastomere movement (BMov) occurs after the first cell division in human embryos. This movement has been suggested as a prognostic parameter for pregnancy outcome prediction following cleavage-stage embryo transfer. However, the e

Cryopreservation of mature oocytes and embryos has provided numerous benefits in reproductive medicine. Although successful cryopreservation of germinal-vesicle stage (GV) oocytes holds promise for further advances in reproductive biology and clinica
