<h2>Ovulation</h2>
Explanation:
Women are born with approximately one to two million ova while female fetuses actually have far more egg cells when they are in the mother’s womb—sometimes as many as six or seven million eggs
- When egg cells are immature they are referred to as oocytes
- By the time a woman reaches puberty, there are only a small fraction of oocytes left—usually about 300,000
- During the reproductive lifespan, only about 500 of a woman’s eggs are ovulated
- The remaining eggs that are left behind die out during menopause
- Egg death is a natural part of the cycle of the female reproductive system so prior to menopause, women typically lose a thousand or so eggs every month
