Embryo transfer is a common technique in broodmare practice. The goal of this review is to provide a practical clinical perspective to various aspects of equine embryo transfer.
The objectives of embryo transfer in mares are i) to produce several foals from the same mare during a single breeding season, eventually bred by different stallions; ii) to allow donor mares to pursue their sport career while recipient mares carry their foals; and iii) to obtain foals from mares with genital lesions or diseases which preclude t...

Embryo transfer has been under development for over a 100 year and has developed greatly since its first successful attempt in 1890 in rabbits. Embryo transfer itself involves the removal of an embryo from the uterus of one mare, and the transfer of the embryo into the uterus of another mare.
Success in an embryo transfer program is dependent on (1) the ability of the mare to ovulate, (2) the act of fertilization in the oviduct, (3) transport of the embryo into the uterus, (4) survival of the embryo until the day of recovery, and (5) pregnancy rate after transfer of the recovered embryo into a recipient.
The purpose of this article is to give the reader an overview of an embryo transfer programme and the separate phases involved. The factors that determine the success of such a programme are considered in detail, particularly the effect of semen quality, embryo quality and recipient mares.
