Risk factors for placenta accreta spectrum in pregnancies conceived after frozen –thawed embryo transfer in a hormone replacement cycle

Placenta accreta spectrum (PAS) is defined as abnormal adhesion of the placenta to the uterine wall after delivery due to direct placental trophoblast invasion into the myometrium [1]. PAS is a serious and life-threatening complication in pregnancy that involves massive postpartum haemorrhage and often requires caesarean hysterectomy [2 –4]. Retained products of conception following delivery at ≥24 weeks of gestation occur mostly as a consequence of focal placenta accreta [5,6]. In developed countries, the prevalence of PAS has increased by approximately 10-fold over the last four decades [1,7].
