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.
We generally try to get about 10-18 eggs at the egg retrieval procedure. IVF success rates correlate with the number of eggs retrieved. There are several ovarian stimulation medication protocols that are used to pump up the ovaries to make enough follicles and eggs. Without stimulating medications, the ovaries make and release only 1 mature egg per menstrual cycle (month).
