Embryo implantation. The initial step of a successful pregnancy is crucial for understanding its biological basis and addressing the challenges of infertility. The aim of this study is to establish a consistent platform for analyzing embryo-endometrium interactions under controlled conditions.

Based on this in vitro model, we found that ultra-high concentrations of estrogen significantly reduce the embryo implantation rates, whereas progesterone supplementation could dose-dependently alleviate these negative effects. This study offers new insights and therapeutic strategies for improving pregnancy rates in fresh embryo transfer during controlled ovarian stimulation for IVF. Compared to a three-dimensional culture system, this in vitro model offers a simple, rapid, and cost-effective platform that can be established in most laboratories and exhibits high reproducibility and reliability, making it an advantageous tool for research and development in the field of reproductive biology.
