Zeta potential of sperm
The mature sperm cell has a negative "zeta" electropotential after acquiring epididymal proteins and sticks to the surface at the: (1) acrosome tip (2) postacrosome (3) midpiece (4) tailtip or (5) entire surface. Fertil Steril 2006;85:481.

2 PN zygotes without nucleoli

This patient had 26 M2 oocytes in the OPU. The fertilization rate is 77%. 11/20 of the fertilized zygotes had no nucleoli. 2 had very small nucleoli.

Multinucleated 2-cell embryo

Multiple nuclei are seen in both cells. Multinucleation has been correlated with increased chromosomal abnormalities, lower blastocyst development rate, and lower chance of implantation and successful pregnancy.
