Topic:Assisted Reproductive Techniques

Assisted Reproductive Techniques (ART) in horses encompass a range of technologies designed to aid in the breeding process. These techniques include artificial insemination, embryo transfer, intracytoplasmic sperm injection (ICSI), and oocyte transfer. ART is employed to enhance reproductive efficiency, manage genetic diversity, and support breeding programs for both commercial and conservation purposes. Artificial insemination involves the collection and deposition of semen into the mare's reproductive tract, while embryo transfer entails the collection of a fertilized embryo from a donor mare and its implantation into a recipient mare. ICSI involves the direct injection of a single sperm into an oocyte to achieve fertilization. Oocyte transfer involves the transfer of an oocyte from one mare to another for fertilization and gestation. This page compiles peer-reviewed research studies and scholarly articles that examine the methodologies, advancements, and applications of assisted reproductive techniques in equine reproduction.

Hysteroscopic insemination of small numbers of spermatozoa at the uterotubal junction of preovulatory mares.
   April 13, 2026  
Mares were inseminated with motile spermatozoa suspended in 30-150 microliters Tyrode's medium directly onto the uterotubal papilla at the anterior tip of the uterine horn, ipsilateral to the ovary containing a dominant preovulatory follicle of > or = 35 mm in diameter, by means of a fine gamete intrafallopian transfer (GIFT) catheter passed through the working channel of a strobed light videoendoscope. Insemination of 10, 8, 25, 14, 11 and 10 mares with, respectively, 10.0, 5.0, 1.0, 0.5, 0.1 or 0.001 x 10(6) motile spermatozoa resulted in conception rates of, respectively, 60, 75, 64, 29,...
