ABSTRACT
Principles of Embryo Transfer Embryo transfer refers to the removal of an embryo from the reproductive tract (i.e. the uterus) of one mare and the transfer of that embryo into the reproductive tract of another mare. Embryo transfer is now a common reproductive procedure in the equine breeding industry. The number of reproductive centers, breeding farms, and veterinary clinics specializing in embryo transfer has increased dramatically in the past 10 years. Advances in collection procedures, transfer techniques, equipment, flush media, embryo shipment and cryopreservation have enhanced the success and therefore the clinical use of embryo transfer in horses.
