Risk factors for twin pregnancy in women undergoing double cleavage embryo transfer.

ABSTRACT:

Background

Two or more embryo transfers have been used to increase the success rate of live birth in traditional in vitro fertilization (IVF) strategy at the expense of increased risks of multiple pregnancy and adverse perinatal outcomes. The decision regarding the elective single embryo transfer or double embryo transfer remains inconclusive. The aim of this study was to investigate the risk factors for twin pregnancy in IVF.

Methods

Participants who underwent their first fresh IVF cycle where two cleavage stage embryos were transferred in Women's Hospital of Zhejiang University between January 2010 and December 2018 were included in this retrospective cohort study. The primary outcome was twin delivery. Secondary outcomes included preterm birth and low birth weight RESULTS
