Review. Rev. mex. de cienc. pecuarias [online]. 2022, vol.13, n.2, pp.473-487.  Epub June 20, 2022. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v13i2.5922.

For many years it has been sought to increase the reproductive efficiency of livestock using biotechnologies such as embryo bisection. However, despite its potential in livestock, its level of adoption is limited. The present work reviews the importance of demi-embryo reconstitution, after bisection, and the main factors that limit its success in livestock. It is possible to increase its level of adoption if it is possible to increase the efficiency currently obtained with this technique, this can be achieved by making a more precise selection of the embryos subjected to bisection. Embryo quality is one of the most important factors related to the potential to reconstitute into viable demi-embryos after bisection, which can be used with greater reliability in embryo transfer programs.

Keywords : Embryo bisection; Demi-embryo reconstitution; Embryo development.
