title: Dextropreponderance of corpus luteum rupture. A clinical study.
abstract: A retrospective study of 55 consecutive patients with cystic corpora lutea, corpus luteum cysts or hematomas was undertaken to verify the observation of a right-side predominance in the incidence of rupture. Thirty-nine patients had a ruptured corpus luteum diagnosed surgically and confirmed histologically. No difference was observed in the overall distribution, the volume of hemorrhage or the size of the cysts between the two sides. A statistically significantly higher incidence of rupture was found on the right side (81.25%) as compared to the left (56.52%). We propose a working hypothesis of a difference in the ovarian venous architecture that causes a higher intraluminal pressure in the right corpus luteum and the dextropreponderance of ruptures.
