Chromatin differences between the first and second polar bodies may depend
upon the sequential appearance of substances regulating chromatin

In ICSI cases, which only account for about 40% of all ART cases performed, the
only morphological features that are generally considered are: is the oocyte
mature/MII (have a visible polar body)? Are sperm motile and the correct shape?

Gynaecology For Postgraduate And Practitioners
During maturation of the oocyte, the metaphase spindle is formed, meiosis
proceeds and the polar body is extruded. Formation of the first polar body results
from a highly asynchronous cell division at the end of the first meiotic division.
