Risk of ischemic placental disease in fresh and frozen embryo transfer cycles.

ABSTRACT:

Objectives

To evaluate the association of fresh and frozen embryo transfer with the development of ischemic placental disease (IPD), hypothesizing that differences in implantation environment affect placentation and thus pregnancy outcomes.

Design

We performed a secondary analysis of a retrospective cohort study of deliveries linked to IVF cycles.

Setting

Tertiary hospital and infertility treatment center.

Patient(s)

We included all women who underwent an autologous IVF cycle and had a live-born infant or an intrauterine fetal demise (IUFD). We excluded women less than 18 years of age.

Intervention(s)

We compared pregnancies resulting from frozen embryo transfer (frozen) cycles with those resulting from fresh embryo transfer (fresh) cycles.
