<h3>
What are ovaries?</h3>
On either side of your uterus are two tiny, oval-shaped glands called the ovaries. They create and store your eggs (also known as ovum), as well as the hormones that regulate both pregnancy and your menstrual cycle. One of your ovaries releases an egg during ovulation. You can get pregnant if this egg is fertilized by a sperm. Until you reach menopause, your ovaries will continue to release an egg every menstrual cycle. Your ovaries stop releasing eggs during menopause. Your ovaries may occasionally release numerous eggs (this can result in a multiple pregnancy). Menstruation and fertilization both depend heavily on your ovaries. They create the hormones progesterone and estrogen as well as eggs for fertilization.
