Assisted hatching and live births in first-cycle frozen embryo transfers.

ABSTRACT:

Objective

To assess the effect of assisted hatching (AH) on live-birth rates in a retrospective cohort of patients undergoing first-cycle, autologous frozen embryo transfer (FET).

Design

Longitudinal cohort using cycles reported to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System between 2004 and 2013.

Setting

Not applicable.

Patient(s)

Women who underwent first-cycle, autologous FET with (n = 70,738) and without (n = 80,795) AH reported from 2004 to 2013.

Intervention(s)

None.

Main outcome measure(s)

Live births.

Result(s)

Propensity matching was used to account for confounding covariates, and a logistic regression model was constructed to identify the predictors of live-birth rates in relationship to AH. I
