Abstract:
:Oocytes with three or more pronuclei and one or two polar bodies arising after intracytoplasmic sperm injection were analyzed cytogenetically, and the data were used to develop a general model explaining the possible origin of the abnormal pronuclear stages. The mechanisms, either separately or in variable combinations, that induce the appearance of additional pronuclei are: 1) nonextrusion of the second polar body; 2) incomplete chromatid segregation into the extruded second polar body; and 3) dispersal of the oocyte chromatids in the presence of the second polar body formation.
