Achtergrond van het onderzoek
*The correct date of registration is 15-01-2019.*
Rates of elective CSs are rising worldwide. Late sequaelae of CSs related to a niche (CSdefect) include gynaecological symptoms and obstetric complications. A systematic review of Gurol-Urganci (2013) reported a lower pregnancy rate after a previous CS (RR 0.91 CI 0.87-0.95) compared to a previous VD. However the underlying cause is unclear, included studies do not differentiate between indication for fertilisation, embryo transportation, or embryo implantation. Using an IVF population offers the possibility to study the effect of a previous CS on the implantation of embryo’s in relation to a previous VD.
