INTEREST in the use of equine assisted reproduction technologies (ARTs) such as intracytoplasmic sperm injection (ICSI) has rapidly increased worldwide in recent years.

The term ART refers to anything other than natural cover and therefore includes artificial insemination (AI), embryo transfer (ET), intracytoplasmic sperm injection (ICSI) and cloning. Semen technologies such as harvesting sperm after death from the testicles and sexing semen (to ensure either a filly or colt foal) are also included.
