Embryo Aneuploidies and Morphokinetics in Ovarian Stimulated and Non Stimulated IVF Cycles (AMOS)

July 21, 2020 updated by: Instituto Valenciano de Infertilidad, IVI VALENCIA

Embryo Aneuploidies and Morphokinetics in Ovarian Stimulated and Non Stimulated Cycles. An Intrapatient Comparison Using Next Generation Sequencing in Biopsy of Blastocysts and Time Lapse Evaluation.

The purpose of this study is to compare the number of euploid embryos obtained per metaphase II oocyte in unstimulated (modified natural cycles) and stimulated IVF cycles.

Detailed Description

Effects of ovarian stimulation on human embryo quality is still a subject of study. When natural and stimulated cycles have been compared, no differences have been observed in terms of embryo cleavage capacity, oocyte and embryo aneuploidy rate or incidence of aneuploidy in aborted foetuses. When mild and conventional doses of gonadotropins have been compared, a higher proportion of good morphological quality embryos are observed in the former. On the contrary, we showed that ovarian stimulation does not increase significantly the embryo aneuploidy rate in IVF derived human embryos when unstimulated and stimulated cycles were compared in oocyte donors. In this study, we want to compare the embryo aneuploidy rate between unstimulated and stimulated cycles in infertile patients, subjected to both IVF cycles with blastocyst biopsy and NGS-PGS. A comparison of the morphokinetics will also be performed.
