About this trial
As embryo ploidy is a crucial factor not only for implantation but also for maintenance of a pregnancy, the aim of this study is to evaluate the impact of the CS / isthmocele on the ongoing pregnancy rates and the implantation site in single euploid frozen embryo transfer, independent of the endometrial preparation approach.
