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.
So the number of egg-containing follicles remaining in the ovary undergoes a steady decline from an average of 400,000 eggs at age eighteen to an average of 25,000 eggs by age thirty-seven. After age thirtyseven or thirty-eight, there is then a very dramatic acceleration of the monthly decline of remaining eggs.
To date, USC Fertility has cryopreserved the oocytes of more than 150 women. Of those who have returned for their eggs, 15 of 21 (65%) have delivered babies. There are two standards to judge egg freezing.sually 3-4 embryos are transferred in women up to 38 years of age. We therefore recommend that 10 eggs be stored for each pregnancy attempt. Most women 38 years of age and under can expect to harvest 10- 20 eggs per cycle.
