Ovaries

Abnormalities in the sex organs of the female are, for the most part, due to developmental deviations. Anomalies of the reproductive tract are more frequent in women than men (1.5-2.0/1).

Incomplete or modification of its descent from the abdomen affect the final position of the ovary. It may retain its original suprapelvic position and lie above or upon the psoas major muscle. If the female gubernaculum (ovarian ligament) fails to adhere to the uterus the ovary may follow the round ligament and pass partly or entirely through the inguinal canal into the labium majus.

The adult ovary may present marked deviations from its typical form, sometimes being unusually long, spheroidal, flattened, triangular, crescentric, or otherwise irregular.

Supernumerary ovaries, varying in size, are not infrequent, occurring in 2-5% of women. In one study of 500 autopsies (Testut), supernumerary ovaries were found 23 times (or 4.6%).

Their usual location is variable in parous women, because they are displaced in the first prequency and probably never return to their original location. Also variably mobile, they may change position according to intestinal activity. In nulliparous women, in the upright position, their long axis is verticle; it has lateral and mesial surfaces, tubal and uterine extremities and mesovarian and free borders. They occupy the ovarian fossae on the lateral pelvic wall.

Isolation of ovarian anlage result in normal follicle-bearing ovarian tissue.

The ovaries may themselves may be the site of displaced adrenal or thyroid tissue.

Absence of one or both ovaries is extremely rare.

An ovary may become involved in inguinal hernia; the displacement of the ovaries into the rectouterine pouch (of Douglas) has also been reported.
