The remaining stages of the meiotic division will not begin until years later, when her egg has finally matured in a developing follicle and the LH surge at midcycle causes the egg to resume meiosis.

Very complex events are taking place in the egg during this monthly development and growth of the follicle. When it comes to prioritizing your sexual and reproductive health, selecting a contraceptive that will both protect against STIs and prevent unplanned pregnancy is key. After nine months, the baby is ready to be pushed out of the uterus by the mother during labor. This is an equal division in which fortysix chromosomes are still left within the egg nucleus. Next, the follicle expands to form a fluid-filled cavity around the egg.

Once penetration of the zona has begun, it requires an average of twenty minutes for the sperm to get completely through; once the sperm has broken through, it plunges directly into the egg membrane itself in less than a second.

Penetration of the egg membrane by the sperm head also sets in motion the second meiotic division of the egg with the release of the second polar body. Females are born with 1 to 2 million immature eggs, about of which are released over the course of her reproductive years, beginning with menarche and ending with menopause.
Under the influence of the midcycle LH surge, the wall of the follicle weakens and deteriorates, and a specific site on its surface ruptures. At the same time, the female nucleus which is sitting on the opposite side of the egg is triggered to undergo its second meiotic division shortly after sperm penetration and become the female pronucleus.
