Embryotechnologies in current system of Equine reproduction

Summary

# Editorial Summary Modern embryotechnologies have become increasingly central to equine breeding programmes worldwide, and this review examines the current state of in vivo and in vitro reproductive techniques that are reshaping how breeders approach genetic selection and mare management. The paper synthesises global and Russian developments across oocyte pickup (OPU), in vitro fertilisation (IVF), intracytoplasmic sperm injection (ICSI), cloning and the production of in vitro-produced (IVP) embryos, alongside traditional embryo transfer protocols. Key findings highlight substantial technical progress in these advanced reproductive methods over the past decade, with particular momentum in Russia where breeder interest in embryo transfer has notably increased. For equine professionals, this revival of embryotechnologies offers practical pathways to extend the reproductive lifespan of valuable mares, bypass certain subfertility issues, and preserve genetics from high-performing animals—though integration of these techniques into routine practice will require investment in specialist facilities and training. Understanding the capabilities and limitations of OPU-derived embryos, in vitro fertilisation success rates, and the regulatory landscape around cloning will be essential for vets, nutritionists and breeders advising clients on reproductive strategy.
