Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta- human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.
A luteoma is a tumor that occurs in the ovaries during pregnancy. It is associated with an increase of sex hormones , primarily progesterone and testosterone .

A corpus luteum cyst or luteal cyst is a type of ovarian cyst which may rupture about the time of menstruation, and take up to three months to disappear entirely. A corpus luteum cyst does not often occur in women over the age of 50, because eggs are no longer being released after menopause. Corpus luteum cysts may contain blood and other fluids.
Follicular cyst of ovary: Can occur after menopause, or during childbearing years [36] Theca lutein cyst: Normally occurs postpartum [37] Chocolate cyst: Presence of this type of cyst is an indicator of endometriosis [38] Ovarian germ cell tumors: Benign [39] Dysgerminoma: Typically occurs in young women between the ages of 10–30 years of age ...
The granulosa lutein cells do have aromatase, and use it to produce estrogens, using the androgens previously synthesized by the theca lutein cells, as the granulosa lutein cells in themselves do not have the 17α-hydroxylase or 17,20 lyase to produce androgens. [5] Once the corpus luteum regresses the remnant is known as corpus albicans. [12]
The follicular cyst of the ovary is a type of functional [1] simple cyst, and is the most common type of ovarian cyst. Signs and symptoms.
Thecomas or theca cell tumors are benign ovarian neoplasms composed only of theca cells. Histogenetically they are classified as sex cord-stromal tumours . They are typically estrogen -producing and they occur in older women (mean age 59; 84% after menopause ).
