endometrioma
Pronunciation: en-doh-mee-tree-OH-mah
Ovarian cyst containing endometrial tissue and blood, associated with endometriosis and fertility impairment.
Full Definition
An endometrioma, also called a chocolate cyst, is a type of ovarian cyst that forms when endometrial tissue grows within the ovary, creating a cyst filled with old blood and endometrial debris. These cysts are a manifestation of endometriosis and can significantly impact fertility by affecting ovarian function, reducing ovarian reserve, and creating pelvic adhesions. Endometriomas may interfere with oocyte retrieval procedures and can reduce the response to ovarian stimulation. Treatment options include surgical removal, though this carries the risk of further reducing ovarian reserve, or management with hormonal suppression.
Usage
Usage note: Distinguish from other ovarian cyst types; note impact on fertility treatment planning.
