Abstract
Objective: The present study aimed to demonstrate the possible effects of increased 2-arachidonoylglycerol (2-AG) by applying the monoacylglycerol lipase inhibitor KML-29 on rats with ovarian ischemia-reperfusion (IR) model. Methods: Forty-eight female Wistar albino rats were divided into six groups. Group 1: Sham, Group 2: Ischemia, Group 3: IR, Group 4: IR + KML-29 (2 mg/kg), Group 5: IR + KML-29 (20 mg/kg), and Group 6: IR + vehicle (dimethyl sulfoxide). Three hours of ischemia followed by 3 h of reperfusion. Two different doses of KML-29 (2 and 10 mg/kg) were administered intraperitoneally in Groups 4 and 5, 30 min before reperfusion. Ovarian IR injury and ovarian reserve were evaluated histopathological and by using nuclear factor (NF)-κB, interleukin (IL)-1β, tumor necrosis factor (TNF)-α, transforming growth factor (TGF)-β1, superoxide dismutase, glutathione peroxidase pre-/postoperative blood antimullerian hormone, and inhibin B. Results: In the KML-1 and KML-2 groups, this damage was significantly reduced compared to the ischemia group. NF-κB, IL-1β, TNF-α, and TGF-β1 immunoreactivities increased statistically significantly in the ischemia group compared to the control group (p<0.001). Immunoreactivities of these proteins were significantly decreased in the KML-1 and KML-2 groups (p<0.001). It was observed that the number of these apoptotic cells decreased significantly in the KML-1 and KML-2 groups compared to the ischemia group (p<0.001). The postoperative inhibin level showed a significant decrease in the ischemia group compared to the sham group, while a significant increase was observed in the KML-1 and KML-2 groups compared to the ischemia group. Conclusion: It was seen that anti-inflammatory, antioxidant, and antiapoptotic activity was formed, and the ovarian reserve was preserved with 2-AG in ovarian IR damage. The protective effect of endocannabinoids on the ovaries may create a promising new treatment strategy for many pathologies that will affect the ovarian reserve.

Abstract
Purpose To investigate differences in reproductive outcomes among patients before and following ovarian torsion. Study design In this retrospective cohort study, we investigated the reproductive outcomes of patients who underwent surgery for ovarian torsion between 1988 and 2015 in a tertiary medical center. Data on deliveries before and after ovarian torsion were compared. Results During the study period, 199 women underwent surgery due to ovarian torsion. The majority (91.4%; n = 182) underwent detorsion, and 8.6% (n = 17) underwent unilateral adnexectomy. At the time of the torsion, 27.6% (n = 55) of patients were pregnant. Among women who suffered from ovarian torsion, about half (52%) of the deliveries occurred before the torsion and 48% following the torsion. No significant difference in the live birth rate was noted (p = 0.19). The fertility treatment rate in our cohort was 7.5% before and 5% after the torsion (p = 0.01). In addition, live birth, cesarean delivery, and fertility treatment rates were similar in women who underwent detorsion vs. those who had adnexectomy. Conclusion Surgically treated ovarian torsion does not appear to negatively influence fertility and live birth potential.

Abstract
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.

Abstract
Ovarian ischemia is a gynecological emergency case that occurs as a result of ovarian torsion. Oxidative stress plays a central role in the development of ischemia/reperfusion (IR) injuries. Lycopene (LYC) is a lipophilic, natural carotenoid well known for its antioxidant properties. This study provides information on the potential applications of lycopene. The Wistar Albino rats were distributed into six groups: Sham group (only a laparotomy was performed), Control group [laparotomy and intraperitoneal dissolvent (olive oil)], IR group, IR+olive oil group, IR+LYC 2.5 mg/kg/dose, intraperitoneal group, IR+LYC 5 mg/kg/dose intraperitoneal group. Evaluated in terms of histopathological changes, tissue malondialdehyde levels (MDA), ovarian expressions of phosphorylated nuclear factor-kappa B (p-NF-κB) and the TUNEL method was utilized to show apoptosis of ovarian tissue. There was a significant decrease in MDA, p-NF-κB values and the proportion of apoptotic cells assessed by TUNEL compared to the group that did not receive intraperitoneal LYC in rat injury with IR damage (P<0.05). In histopathological damage scoring, it was observed that the cell damage was significantly reduced in LYC-administered groups. LYC showed significant ameliorative effects on ovary injury caused by IR through acting as an antioxidant, antiinflammatory, and antiapoptotic agent.

Abstract
OBJECTIVE To review our institutional data regarding the management of adnexal torsion (AT) and assess the ovarian conservation rates. DESIGN Retrospective study. SETTING Tertiary children's hospital. PATIENTS Pediatric and adolescent patients with surgically diagnosed AT. Participants (n = 54, mean age 9.80 ± 3.95 years) were identified between June 2010 and May 2019. INTERVENTIONS Surgical management of AT. MEASUREMENTS AND MAIN RESULTS The primary outcome was to determine the ovarian conservation rates in AT cases. The secondary outcomes were to determine the incidence of AT to total emergency department (ED) presentations, decision to operation theater (OT) time in AT cases, return to OT, histopathology, and follow-up with ultrasound to determine ovarian function. Data were collected on demographic and clinical characteristics. Continuous data were compared with t tests or Kruskal-Wallis tests; categoric data were compared with chi-square tests. A total of 52 (96.29%) patients had ovarian conservation, and 53 (98.14%) had laparoscopic management. The incidence rate for AT cases to total ED presentations for the last 10 years was 9.9 per 100 000, which was based on a Poisson distribution. Presentations to an ED for AT cases have trended upward since 2010. Decision to OT time was statistically significantly shorter in cases with preoperative suspicion of AT than those with intraoperative diagnosis of AT (p = .000). A total of 7 (12.96%) patients returned to OT for suspicion of recurrent torsion. Of these, 5 (9.26%) had confirmed repeat AT. The presence of fever, pain duration, severity of pain, and severity of torsion did not correlate with the follow-up ultrasound findings of ovarian activity. CONCLUSION The findings from our study suggest that high ovarian conservation rates are achievable in AT cases. A high index of suspicion is required to prevent a delay in surgery.
