Ovarium torsion is a gynecological emergency that is common in women of reproductive age and requires early diagnosis and intervention. In this study, we aimed to investigate the long-term anatomical, histological and biochemical protective effects of lamotrigine in ovariums in the ischemia – reperfusion (I–R) model created experimentally in rats. A total of 40 female Sprague-Dawley rats, 14 weeks old, weighing 220–270 g were used in the study. The subjects were randomly distributed to form 4 groups named SHAM group, I - R group, I - R + Lamotrigine (LTG) group and R + LTG group. Under general anesthesia, the ovaries of the rats were reached and ischemia was created for 3 h with vascular clamps. 20 mg / kg LTG was administered intraperitoneally (ip.) to group 3 30 min before ischemia and to group 4 30 min before reperfusion. At the third hour of ischemia, the vascular clamps were opened and the abdomen of the rats was closed according to the surgical procedure. The rats were followed up for 28 days postoperatively and the ovarium tissues taken on the 28th day were examined anatomically and histologically. Biochemically, estradiol (E2), follicle stimulating hormone (FSH) and antimullerian hormone (AMH) levels were measured from blood samples taken from their hearts. Granulosa cells with diffuse vaculations were observed in degenerative follicles in group I-R. Again in this group, severe hemorrhage, fibrosis and edematous areas were observed in the ovarium stroma (Ovarian Histopathological Scoring (OHS): 7). In the I - R + LTG group, OHS was statistically significantly lower than the I - R group (OHS: 2; p < 0.000). In the R + LTG group, although the OHS score was calculated to be lower than the I - R group, there was no statistically significant difference (OHS: 6; p > 0.05). The protective effect of LTG against experimentally created ischemia and reperfusion damage was determined anatomically and histologically. No protective effect of LTG was observed in terms of FSH, E2 and AMH values measured from the blood sera of rats. These findings may provide a basis for future studies using LTG to treat ovarian ischemia-reperfusion injury.
