Prospective cohort study in high responder oocyte donors using two hormonal stimulation protocols: impact on embryo aneuploidy and development.

Background: Ovarian stimulation regimens for in vitro fertilization seem to have a deleterious effect on oocyte quality and embryo aneuploidy in a dose-dependent manner. This study aims to test the influence of gonadotrophin doses on embryo aneuploidy rates.

Methods: A total of 32 young oocyte donors with a high response to ovarian stimulation, were included in the study.
