Bridging the gap between basic research and commercial application at scale for in vitro bovine embryo production

Abstract

Abstract The rapid expansion of in vitro embryo production (IVP) in cattle has established this technology as a major driver of genetic progress and production efficiency. Despite widespread adoption, IVP systems remain inherently inefficient, with substantial losses occurring from oocyte to blastocyst and variable outcomes following transfer. At the same time, significant advances in the understanding of oocyte competence and embryo biology have occurred. However, this knowledge has not consistently translated into improvements in commercial embryo production. The purpose of this review is to examine the gap between basic discovery and field application in bovine IVP and to define the biological and operational factors that limit successful translation at scale. A central constraint is the fundamental difference between systems optimized under controlled laboratory conditions and those required to perform consistently across diverse donor populations, laboratory environments, and high-throughput workflows. Biological variability, metabolic regulation, and the complexity of embryo physiology intersect with operational feasibility, including scalability, cost, and workforce constraints, to limit adoption of new approaches. A structured translational pipeline, from discovery through proof of concept, development, and implementation, is required to align mechanistic insight with commercial realities. Successful translation depends on integrating biological understanding with system robustness, evaluating outcomes beyond early developmental endpoints, and aligning research and industry priorities throughout the development process. Strengthening the collaboration between research and industry is essential for continued innovation and growth of bovine IVP systems.
