Developing reliable models that capture the complexity of maternal– embryonic interactions and implantation is essential for deepening our understanding of early embryonic development as well as the underlying mechanisms of reproductive disorders. Conventional two-dimensional (2D) culture systems, however, fall short in accurately replicating the dynamic and multilayered in vivo microenvironment. In contrast, three-dimensional (3D) organoid technologies have recently emerged as a transformative approach, offering structurally and functionally relevant platforms that better reflect physiological conditions. This review highlights the latest strategies, innovations, and methodological advances in employing 3D organoids to model maternal–embryonic communication and implantation processes. It also outlines their growing potential in research applications and personalized medicine, particularly within the context of assisted reproductive technologies. Furthermore, the review discusses future directions for organoid-based studies from the endometrium, oviduct, ovary, testis, and epididymis have been established, their integration with gametes and embryos marks a new frontier. Cross-species work, especially your pioneering studies on endometrial organoids and lacunoids/cystoids, opens translational opportunities for understanding maternal–embryonic crosstalk, implantation biology, and fertility disorders. The review will discuss current advances, technical challenges, and future directions toward interconnected organoid systems (organoid-on-chip).
