Interpregnancy Interval After Clinical Pregnancy Loss and Outcomes of the Next Frozen Embryo Transfer.

ABSTRACT:

Importance

The optimal interpregnancy interval (IPI) after a clinical pregnancy loss (CPL) remains controversial. Few studies have addressed the role of the IPI after a preceding CPL during in vitro fertilization (IVF) treatment.

Objective

To evaluate the association between different IPI lengths after a preceding CPL and pregnancy outcomes of the next frozen embryo transfer (FET).

Design, setting, and participants

This retrospective cohort study was conducted using data from the Center for Reproductive Medicine of Shandong University in China. The study included women who underwent frozen-thawed blastocyst transfer between July 1, 2017, and June 30, 2022, within 1 year after a preceding CPL during IVF treatment. Follow-up for pregnancy outcomes was completed for all
