Sometimes, a small sample of tissue may be taken with small tools inserted through the vagina during a transvaginal ultrasound. In all three types of pelvic ultrasound, the transducer sends the reflected sound waves to a computer, which makes them into a picture that is shown on a video screen.
Before birth, a fetus starts with around 2 million eggs in each ovary. Those eggs are trimmed down over time, and a girl is born with around 300,000 eggs in each ovary. She â¦normally releases 1 egg a month during her fertile years.
What are the ovaries and what is their function? Women normally have two ovaries that store and release eggs. Each ovary is about the size of a walnut, and one ovary is located on each side of the uterus. One ovary releases an egg each month, and this process is called ovulation. Ovulation occurs in roughly the middle of a woman's monthly menstrual cycle. The egg is enclosed in a sac called a follicle.
