Day 2 versus day 3 embryo transfer in patients with in vitro fertilization and only one zygote with two pronuclei.

ABSTRACT:

Objective

This study aimed to compare the pregnancy outcomes of Day 2 (D2) fresh embryo transfer and D3 fresh embryo transfer in women with only one zygote with two pronuclei (2PN).

Methods

Data on 432 in vitro fertilization-embryo transfer cycles with only one 2PN zygote from January 2016 to January 2022 were retrospectively collected. A total of 302 fresh embryo transfers on D2 (n = 193) and D3 (n = 109) were analyzed, and pregnancy outcomes were compared.

Results

The patients' characteristics were not different between D2 and D3 embryo transfer. There were no significant differences in the rates of clinical pregnancy, early abortion, or live birth between D2 and D3 embryo transfer. A multivariate logistic regression model controlling for age, the fertilizati
