Oocyte


Meiosis video


Ovulation video

Oocyte is the immature egg which is first formed after the last mitotic division that produces the most immature egg called the primary oocyte. Primary oocyte enters into the first meiotic division to produce two daughter cells called secondary oocytes. They are released at the second meiotic division which is  arrested at 2nd metaphase stage and released at ovulation. At the penetration of the sperm cell, the secondary oocyte completes its second meiotic division to become the ovum. The ovum pronucleus is fertilized by the sperm pronucleus.
