(Top) Transverse TA ultrasound at the level of the uterine fundus in a 23-year-old woman shows the right ovary in the typical position of
the ovarian fossa. The fallopian tube and broad ligament can sometimes be seen as a band of tissue connecting the ovary to the uterine
horn. Ovarian ligaments can be lax making ovarian position quite variable from above the fundus to the posterior rectouterine pouch of
Douglas. (Middle) Transverse TA ultrasound of the ovary in a neonate is shown. The size of the ovary is enlarged with a dominant
follicle related to stimulation from residual maternal gonadotrophins. Visible follicles may persist until 9 months of age or longer.
(Bottom) Longitudinal TA ultrasound of the ovary of a 5-month-old girl. The ovary is slightly prominent due to stimulation from
maternal hormones. The ovary is small (total volume of 1.7 cc) with immature follicles of variable size (usually less than 0.9 cm). The
size of the ovaries change very little in the first 6 years of life.
