The ovaries are located in the female pelvic region; they’re comprised of two small organs approximately the size of your thumb. Each one flanks the uterus, to which they’re attached, near the fallopian tube’s opening. Within the ovaries are the female reproductive cells known as the oocytes, or eggs.
Within the ovaries are follicles, which are fluid-filled structures in which eggs mature. According to the University of Michigan’s Rogel Cancer Center, current knowledge says that women are born with their lifetime supply of approximately 1-2 million eggs. Furthermore, women aren’t able to make new eggs, and there’s a monthly decrease in the total number of eggs in the ovaries every month.
By the time an adolescent woman has reached puberty, only about 25 percent of her lifetime eggs remain–or 300,000. And over the next 3-4 decades of a woman’s reproductive life, said egg supply will continue to be depleted. And while it’s impossible to tell precisely how many eggs remain in the ovaries at any point, most women begin to see a major decrease in fertility around 37 years of age. By the time they reach menopause, almost no eggs remain.
The ovaries play an important role in the endocrine system. They produce and release hormones known as oestrogen and progesterone, which regulate each menstrual cycle a woman undergoes.
Menopause begins at the conclusion of a woman’s reproductive years, after her final menstrual cycle. It occurs once all egg-containing follicles have been lost. When menopause starts, the ovaries no longer secrete the hormones oestrogen and progesterone, causing menstruation to stop occurring.
All iterations of the Ezra scan cover the ovaries, and screen for various cancerous and precancerous states–such as polyps–within them. If you’d like to learn more about our scanning packages, you may do so by following this link.
