Diagnosis Ultrasound is the primary tool used to document the follicular cyst. If they are large enough, a pelvic exam will also aid in the diagnosis. Treatment Follicular cysts usually resolve on their own in 3-6 weeks. If the yellow body reaches a size of greater than 3 centimeters, it is then referred to as a cyst. Rupture of these cysts occur more often on the right side and occur during intercourse.
Rupture occurs during the later days in the menstrual cycle when the cysts are the largest.
Sometimes they may reach a very large size, which then requires a surgical removal. Oral contraceptive therapy has been known to markedly reduce the risk of the formation of the functional ovarian cyst. This disease process is also known as endometriosis of the ovaries. Tiny implants of cells that line the uterine cavity become transplanted and form small cysts on the outside of the ovary. These cysts enlarge producing endometriosis of the ovary.
