Comparison of early and fully expanded blastocysts on pregnancy and birth outcomes in patients with fresh IVF/ICSI cycles: A retrospective cohort study.

ABSTRACT:

Objective

To investigate the effect of the early blastocyst on pregnancy and birth outcomes in patients in vitro fertilization/(early rescue) intracytoplasmic sperm injection-embryo transfer [IVF/(early rescue)ICSI-ET] cycles.

Methods

In this retrospective cohort study, 289 patients with single-blastocyst transfer within IVF/(early rescue)ICSI-ET treatment cycle were included and divided into the early (n = 48, Gardner stage = 1 or 2) and the fully expanded blastocyst (n = 241, Gardner stage ≥ 3) groups. The differences in pregnancy and birth outcomes between the two groups were compared.

Results

There was no significant differences between the two groups in baseline indicators, including demographic characteristics and clinical treatment (P> 0.05).The clinical outcom
