IB research: embryo asymmetry linked to future aneuploidies study

As a result of work carried out by our human biology team, results of research work shall be presented over the coming days in the VIII edition of the ASEBIR Congress in San Sebastian. The research evaluates if embryo symmetry during early development stages has an effect on chromosomal abnormality rates found following genetic analysis of embryos in the blastocyst stage. In order to carry out the research, specific software was used which captures embryonic cell images and measurements on the second and third days of development. Asymmetric embryos tend to produce poor quality blastocysts on day 5 of embryo development. Those which manage to develop and give rise to good quality blastocysts and, as a result, are able to undergo the embryo biopsy required for genetic analysis, have aneuploidy rates which are identical to those of symmetrical embryos observed on days 2 and 3 of embryo development.
