second polar body

This results in the production and extrusion of the second polar body.

The daughter cell then divides again to form a small "second polar body" and a larger ovum.

Fertilized eggs can be distinguished from those that are unfertilized within hours of fertilization by their prominent second polar body (Figure 1, panel 5).

The first and second polar body of the oocyte are extruded at the time of the conclusion of the meiotic division, normally the first polar body is noted after ovulation, and the second polar body after fertilization.
