Co-localization of decondensed supernumerary sperm in peripheral small cleavage furrows suggested that decondensation of sperm nuclei is a prerequisite for the short-lived supernumerary sperm-associated peripheral cleavage furrows. Our analysis shows that the most significant stage at which the slower developing rhesus embryos demonstrated a lag in cleavage was at the 5—8 cell duration. However there was a group of embryos that only reached early blastocyst by day 6. The presence of micronuclei seen in these embryos could be due to daughter cells that subsequently exit mitosis due to abnormal chromosome complements thus preventing participation in mitosis followed by a combination of necrotic and apoptotic cell death The pronucleus fuses with the egg nucleus, regenerating 2N chromosomes. Since the XXO embryos typically were observed as arrested by day 3, the culture of the XXO embryos was stopped on day 2.
