Is the Ploidy Status of the Embryo Impacted by Gonadotrophin Dose?

Background: There has been much debate and concern about whether the dose of exogenous gonadotrophins used for controlled ovarian stimulation (COS) adversely affects the selection of leading follicles and potentially impacts the quality of the eggs retrieved and the embryos created. The ploidy status of the embryo, as assessed by pre-implantation genetic testing (PGT), is used as a measure of embryo quality.
