No results posted yet for this study

Summary

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.

Conditions

Interventions

DIAGNOSTIC_TEST

Ultrasound between 6+0 and 6+7 weeks of pregnancy - With Isthmocele

Location of implantation of the GS (gestational sac) amended to Naji et al, defined as 3 possible implantation sites: (A: fundal, B: anterior, C: posterior) Size of isthmocele: * Depth of isthmocele * Width of isthmocele * Circumference of isthmocele Distance between isthmocele and outer cervical os (measured with the trace line) Distance between CS scar and outer cervical os (measured with the trace line) Size of gestational sac Measurements of the isthmocele size / circumference / distance between isthmocele / CS and outer cervical os
