Ovarian torsion is a gynecological emergency that requires immediate surgery. This very rare condition results from the rotation of the ovary along its pedicle that holds it in place. Such a rotation blocks the ovarian artery and sometimes the ovarian vein as well to break off the blood supply to the ovary resulting in severe abdominal pain. https://www.brooklynabortionclinic.nyc/ovarian-torsion-obstetric-and-gynecologic-emergencies/
