The ovaries are situated immediately caudal to the kidneys and thus lie at the level of the third or fourth lumbar vertebrae. They are attached to the dorsolateral wall of the abdominal cavity by the broad ligaments and to the middle and ventral thirds of the last one or two ribs (dog) or to the diaphragm (cat) by suspensory ligaments. The ovaries are connected to the cranial ends of the uterine horns by the proper ligaments of the ovary (Fig. 7–1). The ovaries are in the dog completely and in the cat partially enclosed in a peritoneal pouch, the ovarian bursa. The ovarian bursa contains the uterine tubes and is usually opaque in the dog due to its fat content (Fig. 7–2). The surfaces of the ovaries, which are free of serosa, are covered by germinal epithelium. Germ cells from the germinal epithelium of the cortex grow inward and follicles, many of which degenerate and become atretic, develop. During the follicular phase tertiary follicles grow and can be seen macroscopically at the surface as follicular fluid increases. Lateral to the ovaries, the infundibula are opened to collect ovulated ova. In the dog the fimbriated extremities lie maily in the ovarian bursae, but generally a portion protrudes through the slit-like opening of the bursa.
