In-vitro embryo production and transfer technology in
cattle: An updated review article
The use of in vitro technique with domestic animal gametes and the methods of
embryo manipulation for assisted reproduction is currently the most advanced
method in cattle breeding with regard to scientific research and practice. In vitro
embryo production (IVP) is the process of production of live embryos in the
laboratory rather than in vivo by collecting oocytes from slaughterhouse ovaries
as well as from live donor cows. IVP entails the completion of three biological
steps that are now relatively well established in cattle: oocyte in vitro maturation,
in vitro fertilization and embryo culture. Oocyte maturation is a complex process
involving nuclear and cytoplasmic maturation in appropriate media. To enhance
successful fertilization of matured Oocytes, sperm cells must be motile, have the
ability to undergo capacitation and express the acrosome reaction
