In assisted reproductive treatment (ART), few challenges are as emotionally and clinically complex as Recurrent Implantation Failure (RIF). It is a diagnosis that not only frustrates patients and clinicians but also raises important questions about the subtleties of embryo-endometrial interaction. Despite advances in embryo selection and laboratory techniques, many high-quality embryos fail to implant—suggesting that endometrial receptivity may be a limiting factor in a signi

The success of embryo implantation in assisted reproduction is often tied to endometrial thickness, but this metric alone doesn’t tell the full story. For implantation to occur and sustain, the endometrium must present a receptive, synchronised, and functionally supportive environment. Scientific literature increasingly suggests that molecular receptivity and tissue quality are as critical as structural thickness.  In this post, we’ll explore the biological complexity of the
