Update on equine ICSI and cloning. Conference Paper uri icon

abstract

  • Intracytoplasmic sperm injection (ICSI) has recently become efficient enough to be considered for clinical use. With ICSI, one spermatozoa is injected into a mature oocyte. Harvesting of an oocyte ex vivo, followed by ICSI and transfer of the fertilized oocyte to the oviduct, may be applicable when semen quality is insufficient for standard insemination. Sperm injection, followed by in vitro embryo culture to the blastocyst stage, may be used in cases where multiple oocytes are to be fertilized (e.g. when oocytes are collected post-mortem). Nuclear transfer (cloning) of horses is possible but still inefficient; however, commercial companies currently will culture and store cells from privately owned animals for a reasonable fee. Horse owners are beginning to realize the potential of cloning for salvaging valuable equine genetics that may otherwise be lost.
