Ovarian teratomas do not cause abdominal pain under normal conditions. However, if a patient engages in vigorous activities, it can lead to a torsion of the ovarian teratoma. The torsion of the teratoma can drag the ovary to twist along with it, consequently affecting the blood supply to the adnexa on the affected side, leading to ischemic necrosis of the adnexa, and thus causing a sudden onset of severe lower abdominal pain on one side. In such abnormal situations, the ovarian teratoma can indeed cause lower abdominal pain.
