What is an enlarged ovary?

An enlarged ovary is an ovary that has expanded past its normal size. The cause of this enlargement is often cyst formation. Other causes include endometriosis, benign tumors and, rarely, ovarian cancer.

Many types of cysts can grow within the ovary, such as those called functional cysts that form during menstruation. Another type of cyst is caused by endometrial tissue growing within or on the ovary, as seen with endometriosis. Polycystic ovarian syndrome is a condition in which multiple cysts can develop within a single ovary or both ovaries. Both ovarian cancer and metastatic cancer are rare causes of enlarged ovary.

Depending on the cause, an enlarged ovary may occur in one or both ovaries, and it may be accompanied by symptoms in other parts of the body, such as abdominal pain, fever, or unintentional changes in body weight.

Some women with an enlarged ovary have no symptoms at all, while others may have abdominal pain, abnormal vaginal bleeding, difficulty urinating, or pain during sexual intercourse. In some cases, an enlarged ovary may grow large enough to put pressure on the bladder, making it difficult to expel urine.

Enlarged ovary is rarely a serious condition; however, seek immediate medical care (call 911) for serious symptoms, including severe abdominal pain or high fever (higher than 101 degrees Fahrenheit).

Seek prompt medical care if you are being treated for an enlarged ovary but mild symptoms recur or are persistent.


What other symptoms might occur with an enlarged ovary?

Enlarged ovary may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. Symptoms that frequently affect the ovaries may also involve other body systems. In some cases, an enlarged ovary may not produce any symptoms.

However, in some cases, the enlarged ovary may twist or become dysfunctional. Ovaria... Read more about enlarged ovarycauses
