Synchronization of Meiosis in Porcine Oocytes by Exposure to Dibutyryl Cyclic Adenosine Monophosphate Improves Developmental Competence Following in Vitro Fertilization1

Abstract excerpt

The effect of stage of maturation of the germinal vesicle of porcine oocytes at the time of in vitro maturation on subsequent developmental competence was examined. A large variation exists in the germinal vesicle morphology of oocytes at the time of collection of cumulus-oocyte complexes (COCs) and after culture in the absence of dibutyryl cAMP (dbcAMP) for 20 h. However, the morphology of the germinal vesicle...
