Time-lapse monitoring technologies for the selection of bovine in vitro fertilized embryos with high implantation potential
Over the years, the utilization of in vitro fertilization (IVF) in bovine embryo production has increased globally to accelerate the selection of cows with high genetic values. The selection of embryos with high implantation potential is a critical factor in establishing pregnancy. Time-lapse monito...

| description | Over the years, the utilization of in vitro fertilization (IVF) in bovine embryo production has increased globally to accelerate the selection of cows with high genetic values. The selection of embryos with high implantation potential is a critical factor in establishing pregnancy. Time-lapse monitoring (TLM) has emerged as a new technique that allows frequent and non-invasive imaging of developing embryos. TLM is considered to have several advantages over the conventional morphological evaluation of embryos, which has been widely used in bovine embryo production. Establishing a novel embryo selection algorithm specifically for bovine IVF embryos is a critical challenge, but information on the association between morphokinetic data obtained using TLM and the implantation potential of embryos is still limited. This review outlines the potential application of TLM technology to improve the fertility of bovine IVF embryos, focusing on the results of human and bovine TLM studies that can be applied to select bovine embryos with high implantation potential. First, the progress of the TLM technology in bovine embryo production is summarized. The association between kinetic and morphological parameters and the developmental and implantation potential of human and bovine embryos is outlined. Finally, the benefits of evaluating blastocyst collapse and re-expansion as indicators of bovine embryo viability and the possible application of TLM to detect chromosomal abnormalities and determine embryo sex will be discussed. |
