What is a common complication of untreated ovarian torsion?

Untreated ovarian torsion can lead to ovarian necrosis due to the interruption of blood supply to the affected ovary. When an ovary is torsed, it becomes twisted around its supporting ligaments, leading to vascular compromise. This lack of blood flow results in ischemia, and if not promptly addressed, it can progress to necrosis, where the tissue dies due to lack of oxygen and nutrients. The longer the ovary remains in a torsed position, the higher the risk for permanent damage and loss of function, making ovarian necrosis a significant and serious complication of untreated torsion.

Other options, while they may present clinical scenarios in gynecology, do not relate directly to the consequences of ovarian torsion. Ovarian hyperstimulation syndrome is associated with fertility treatments, anemia is generally not a direct result of torsion, and endometriosis involves the presence of endometrial tissue outside the uterus, which is unrelated to the acute complications arising from ovarian torsion.
