This study found that a history of cesarean section does not significantly impact clinical pregnancy and live birth rates in euploid frozen embryo transfer cycles.
Purpose To evaluate the impact of a cesarean section (CS) on the chance of clinical pregnancy and live birth (LB) in frozen embryo transfer (FET) cycles in the setting of euploid embryos and the absence of intracavitary fluid (ICF) as causes of implantation failure were excluded. Methods Retrospective study, including patients with at least one previous CS or at least one previous vaginal delivery, who underwent a euploid FET cycle. Results A total of 412 euploid embryo transfer cycles had been included. Patients' mean age was 34.5 years and 42.48% of patients have had at least one previous CS. A clinical pregnancy was seen in 69.42% and 60.19% of the patients had a LB. Positive pregnancy test, clinical pregnancy, and LB rate were not significantly different between the groups without/with a history of a previous CS (p = 0.6/0.45/0.94, respectively). LB rate was significantly reduced by the presence of mucus on the ET catheter (OR: 0.413; p = 0.010), the BMI (OR: 0.946; p = 0.006), the combined embryo quality (embryo quality fair: OR: 0.444; p = 0.001; embryo quality low: OR: 0.062; p < 0.001), and by the HRT endometrial preparation approach (OR: 0.609; p = 0.023). Conclusion The possible negative impact of a CS can be overcome when a euploid FET after exclusion of ICF is performed.
