In recent years, progress has been achieved in the production of pig embryos through IVM and IVF techniques. Cytoplasmic maturation of oocytes has been improved by modifications to IVM procedures. However, the historical problem of polyspermic penetration still remains a major issue to be solved. Recent studies indicate that the type of IVF medium and certain modifications to that medium can reduce polyspermy. Efforts should be directed to increase the developmental competence and quality of embryos. At present, many embryo culture (EC) media are available that can overcome the historical 4-cell block and support development of early in vivo derived embryos to the blastocyst stage. In contrast, blastocyst development of in vitro produced embryos in these culture media varies significantly. Furthermore, morphology and cell numbers in in vitro produced blastocysts are inferior to their in vivo counterparts. However, several modifications to EC techniques have improved embryo quality and developmental competence. Testing embryo viability through surgical transfer to recipient animals has resulted in acceptable pregnancy rates with moderate litter sizes. Although reliable in vitro systems are available for the generation of pig embryos, the problem of polyspermy and poor embryo development hamper their large-scale implementation. Further research efforts should be directed to improve oocyte/embryo quality and the methods to minimize polyspermy through development of novel IVM, IVF, and EC techniques.
