The Assisted Reproduction Technologies (ART) program at Colorado State University's E​​​quine Reproduction Laboratory is one of the most established laboratories of its kind within the equine industry in the United States. CSU pioneered many of the procedures utilized for equine assisted reproductive techniques, and they continue to provide both cutting-edge clinical and research opportunities for horse owners. The use of traditional IVF techniques has not been successful in the horse; therefore, intracytoplasmic sperm injection (ICSI) is used for fertilization in the laboratory setting. Horse owners and breeders need to understand the regulations established within their respective breed registries prior to pursuing these procedures. Enrollment within the ART program at CSU is appropriate for subfertile mares that are unable to become pregnant or donate embryos, as well as stallions within a limited amount of frozen semen.
