The aim of the study is to investigate the effects of unilateral ovarial torsion-detorsion to the contralateral ovary. 4 groups were created, each consisting of 8 Wistar-Albino female rats. Sham operation was performed in Group 1. After the torsion of the unilateral ovary; detorsion procedure was carried on 6 hours later in Group 2, detorsion was performed 12 hours later in Group 3. Unilateral oophorectomy was applied in Group 4 and the oophorectomized tissues were accepted as the control group. 3 weeks after the initial procedures, the rats were again anesthetized and the contralateral ovaries were excised. The specimens were divided for light and electron microscopic investigations. The amounts of normal follicles, corpus luteum, degenerated and atretic follicles were calculated in each group and were compared with each other. In the light microscopic investigation, normal follicle amount was 71 % in control group, 57 % in sham group and was 6.25 %, 33 %, 27 % in Group 2, Group 3 and Group 4 respectively. In electron microscopy; obvious ultrastructural changes and degenerative follicles were found in the contralateral ovaries in Group 2, but also in Group 3 and 4. As a result we demonstrated that severe degenerative changes in contralateral ovary continues even 3 weeks after the unilateral torsion and detorsion of an ovary. While detorsion after a 12 hours period of torsion acts like unilateral oopherectomy; more severe degenerative changes occur in the contralateral ovary following a torsion-detorsion event of 6 hours duration.
