Association of duration of embryo culture with risk of large for gestational age delivery in cryopreserved embryo transfer cycles.

ABSTRACT:

Objective

To examine the relationship between the day of embryo cryopreservation and large for gestational age (LGA) infants in women undergoing frozen embryo transfers (FETs) after cryopreservation on days 2-7 after fertilization and to compare the risk of the day of embryo cryopreservation to other possible risk factors of LGA after FET cycles.

Design

Retrospective cohort study.

Setting

Society of Assisted Reproduction Clinical Outcomes Reporting System.

Patients

Women undergoing FET cycles.

Intervention

Day of cryopreservation.

Main outcome measure

Singleton LGA infant.

Results

A total of 33,030 (18.2%) FET cycles in the study group (n = 181,592) resulted in LGA infants during the study period of 2014-2019. There was an increase in LGA r
