Many physicians choose to suppress gonadotropins with oral contraceptives. The oral contraceptives suppress gonadotropins which support "functional cysts" .
Physiologically normal ovarian enlargement can be due to the development or persistence of follicular or corpus luteum cysts. Follicular cysts are usually thin walled, 2-6 cm in diameter and contain relatively clear fluid. Most regress spontaneously in 1-3 months. Occasionally they can enlarge significantly and may result in bleeding from a rupture in the cyst wall. Large functional cysts and ovarian neoplasms may result in torsion.
