Development of a targeted single molecule sequencing panel for ovarian hyperstimulation syndrome

center. The differences were not attributable to cohort size (blastocysts biopsied). This is the first study to investigate the question of center-dependent aneuploidy controlling for indication and patient population by taking into account only egg donor cycles. The reasons for the observed differences between centers can only be speculated but include any of the factors that are known to affect oocyte and embryo development, such as hormonal stimulation regimes, laboratory conditions, gamete and embryo manipulation methods, or environmental differences. Age is not considered to play a role here since young age is a pre-requisite to anonymous egg donation.
