Frozen embryo transfer outcomes in patients with prior cesarean delivery: a focus on endometrial lining parameters

Although patients can be reassured that a prior cesarean does not appear to be associated with reduced endometrial thickness, receptivity in FET cycles may be diminished, as reflected by lower subsequent live birth rates. One possible explanation is an altered endometrial environment, given the increased risk of cycle cancellation due to endometrial fluid accumulation in patients with prior cesarean delivery.
