Appearance, fate and utilization of abnormal porcine embryos produced by in vitro maturation and fertilization

Kikuchi K. , Somfai T. , Nakai M. , Nagai M.

In vitro production (IVP) including in vitro maturation (IVM) and fertilization (IVF) is now an important technology for obtaining live piglets. However, there are still two significant obstacles to the efficient production of viable porcine embryos: (1) polyspermy and (2) fertilization of oocytes arrested at the immature stage. These phenomena relate to production of embryos with abnormal ploidy (polyploidy). To avoid these problems, careful selection of mature oocytes ...
