Evaluation of Early Frozen Blastocyst Transfer in A True Natural Cycle Protocol in Comparison to A Hormone Replacement Protocol: A Single-Center Cohort Study [PDF]
International Journal of Fertility and Sterility, 2023 Background: Timing of frozen embryo transfer (FET) within a purported window of implantation is of increasing interest,and there is a paucity of evidence surrounding the transfer of frozen embryos early within these frozen embryo transferprotocols.

Cytokines That Serve as Embryokines in Cattle
Animals, 2021 The term “embryokine” has been used to denote molecules produced by the endometrium, oviduct, or by embryo itself that will influence embryo development. Several cytokines have been identified as embryokines in cattle and other mammals.

Mitochondrial reactive oxygen species regulate mitochondrial biogenesis in porcine embryos
The Journal of Reproduction and Development, 2021 The number of mitochondria in blastocysts is a potential marker of embryo quality. However, the molecular mechanisms governing the mitochondrial number in embryos are unclear.

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 ...

Assessment of aneuploidy concordance between clinical trophectoderm biopsy and blastocyst
Human Reproduction, 2018 STUDY QUESTION Is a clinical trophectoderm (TE) biopsy a suitable predictor of chromosomal aneuploidy in blastocysts? SUMMARY ANSWER In the analyzed group of blastocysts, a clinical TE biopsy was an excellent representative of blastocyst karyotype in ...
