Placenta previa in in vitro fertilization and unassisted pregnancies-is there a difference in perinatal outcomes and placental histology?

While PP in non-assisted pregnancies is probably associated with previous CDs, in IVF it is more "sporadic," and may complicate any index pregnancy. A lower placental weight was more prevalent in the control group, supporting the concept that pregnancies complicated by PP following IVF can be attributed to initial abnormal location of placentation, rather than an underlying pathological uterine segment of implantation. Nevertheless, IVF and unassisted pregnancies entail similar perinatal outcomes in cases of PP.
