Figure 25.1.3
Ovary in a woman undergoing treatment for infertility. A: In this woman taking medication to stimulate development of ovarian follicles, ultrasound demonstrates multiple follicles (F) throughout the ovary. These occupy a relatively larger portion of the ovary than they do in a normal, nonstimulated ovary. B: Follicle measured (calipers) in another women taking medication to stimulate follicular development.

Figure 25.1.4
Normal ovary in a postmenopausal woman. A: Sagittal and (B) coronal transvaginal images demonstrate the right ovary (calipers) in a postmenopausal woman. The ovary is small and homogeneous, without the physiologic cysts seen in the typical premenopausal ovary.
