Biomarkers of endometrial receptivity through a minimally invasive approach

摘要

Pregnancy and live-birth rates after in vitro fertilization (IVF) have continued to increase across the past decade and are due to the higher implantation rates, presumably reflecting superior laboratory techniques, introduction of quality management programs, and improved stimulation protocols. This has led to an increasing use of single-embryo transfer in some countries and a significant reduction in embryo numbers transferred in others. This makes identification of the ideal conditions for implantation even more necessary.
