Definitions

Physiologic cysts including follicular and luteal cysts constitute the vast majority of cystic ovarian lesions. They typically result from failure during folliculogenesis, most often from rupture or regression of the ovarian follicles. They may also result from continued hemorrhage in a corpus luteum. Follicle cysts are usually larger than the mature graafian follicle and range from 3 to 5 cm in size; however, they may attain a diameter of 8–12 cm. Physiologic ovarian cysts are an extremely common incidental finding during the reproductive ages. However, they may be found in all age groups, particularly in adolescents and in the early postmenopausal period. Functional ovarian cysts may also develop due to irregularities of pituitary gonadotropin hormone release or due to external hormonal replacement therapy.
