Abstract:

Endometrial receptivity is key to clinical pregnancy by in vitro fertilization-embryo transfer (IVF-ET) technique. Endometrial thickness (EMT) is a major index for pregnancy monitoring, but the optimal time indicating endometrial receptivity is controversially uncertain. Multiple studies have demonstrated the correlation between EMT and IVF pregnancy outcomes and EMT of a moderate range is essential for good pregnancy outcomes and a thin endometrium produces negative pregnancy outcomes. In this paper, we reviewed the research on the impact of EMT on IVF-ET pregnancy outcomes in terms of timing of EMT measurement, clinical pregnancy rate, live birth rate, ectopic pregnancy rate, placenta praevia, and low birth weight, investigating the mechanism of occurrence and treatment of thin endometrium so as to provide clinical references for improving IVF pregnancy outcomes.

Key words: endometrial thickness, thin endometrium, in vitro fertilization-embryo transfer, live birth rate, ectopic pregnancy, placenta praevia
