Why Do Cysts Form On Ovaries?

Cysts form on ovaries as an occasional part of the natural function of the sexual organ, while some of the cysts persist to become an abnormality and others are caused by some disorder or medical condition. Most ovarian cysts, which appear as small fluid containing bubbles, are benign and may even result in no signs and symptoms.

During ovulation, ovaries develop outgrowing structures known as follicles, which may further develop into cysts. These cysts are not usually larger than a pea in size, but become a problem when they grow larger than 5 centimeters in diameter, and especially when they cause much pain and discomfort. Bleeding, abdominal pain, fullness and discomfort are the main symptoms of ovarian cysts. Other symptoms include fatigue, headache, nausea and weight gain.

Ovarian cysts are fluid filled sacs that appear in ovaries. There are largely two types of ovarian cysts, functional and non-functional. Functional cysts occur as a part of the normal menstrual cycle. Non-functional ovarian cysts occur due to a number of conditions and disorders other than the normal menstrual cycle. Non-functional ovarian cysts are due to the polycystic ovary syndrome, endometriosis, ovarian serous or mucinous cystadenoma, hemorrhagic ovarian cyst and number of other conditions such as Dermoid cyst, cystic adenofibroma and borderline tumoral cysts.

Follicular cysts are the most common of the functional cysts and form due to the rupture of the follicles of the ovary during ovulation. These are the most commonly occurring ovarian cysts. Cysts occurring after the ovulation are known as corpus luteum cysts. Thecal cysts occur in the thecal layer of cells in the developing oocytes, during ovulation.

Normally ovarian cysts would subside themselves, but large ovarian cysts which are particularly uncomfortable may be required to be removed by surgery. Ovarian Cysts occur among women of all ages, but mostly during the childbearing years.
