Mode of conception does not appear to affect placental volume in the first trimester.

ABSTRACT:

Objective

To study whether infertility treatments, including IVF and non-IVF fertility treatments, are associated with diseases of placental insufficiency in early gestation. First trimester placental volumes by ultrasound and chorionic villi weight during sampling (CVS) were performed to detect differences between pregnancies conceived spontaneously versus with fertility treatments.

Design

Retrospective cohort.

Setting

Academic tertiary center.

Patient(s)

Women with singleton pregnancies undergoing CVS and first trimester ultrasound from April 2007 to November 2015.

Intervention(s)

Estimated placental volume (EPV) was calculated from ultrasound images using a validated computation and CVS estimated tissue weight was performed using a validated visual an
