In physiological condition, avian sperm can be stored within the sperm storage tubules of female reproductive tract and may able to fertilize eggs up to 15 weeks. The long-term viability and fertilizing ability of sperm is reduced when avian sperm are stored in vitro conditions. The motility, viability and fertilizing ability of avian sperm depends on in vitro storage conditions. Many factors can affect in vitro sperm motility, viability and fertilizing ability such as storage temperature, pH of extenders, osmolarity, sperm dilution rate, and seminal plasma. Researchers are trying to extend longevity of avian sperm during in vitro condition by applying the knowledge of in vivo sperm storage mechanism(s) and sperm biology. This paper reviews the sperm motility, viability and fertilizing ability of main poultry species stored in vitro conditions. This study will help to understand a scenario of in vitro avian sperm motility, viability and their fertilizing ability.
