Study Finds Endometrial Thickness May Not Substantially Impact Live Birth Rates in Single Embryo Transfers

A retrospective, multi-center study involving over 30,000 cycles of single frozen euploid embryo transfers found that endometrial thickness (ET) may not have a significant impact on live birth rates (LBR).

Key Findings:

Overall: ET wasn’t a strong predictor of LBR.
Programmed/Modified Cycles: LBR decreased with ET less than 7mm (22% and 41% reduction respectively).
Natural Cycles: no threshold for ET was found to affect LBR.
Underlying Cause: Researchers suggest a thin lining may be a result of underlying issues affecting implantation, rather than the direct cause of failure.

Study Details:

Conducted across 25 IVF centers in 3 countries.
Data from January 2017 to December 2022.
Median ET across all cycles was 8.9mm.
One author disclosed ties to the biopharmaceutical industry.
