Abstract
The female reproductive system is strongly influenced by nutrition and energy balance. It is well known that food restriction or energy depletion can induce suppression of reproductive processes, while overnutrition is associated with reproductive dysfunction. However, the intricate mechanisms through which nutritional inputs and metabolic health are integrated into the coordination of reproduction are still being defined. In this review, we describe evidence for essential contributions by hormones that are responsive to food intake or fuel stores. Key metabolic hormones-including insulin, the incretins (glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1), growth hormone, ghrelin, leptin, and adiponectin-signal throughout the hypothalamic-pituitary-gonadal axis to support or suppress reproduction. We synthesize current knowledge on how these multifaceted hormones interact with the brain, pituitary, and ovaries to regulate functioning of the female reproductive system, incorporating in vitro and in vivo data from animal models and humans. Metabolic hormones are involved in orchestrating reproductive processes in healthy states, but some also play a significant role in the pathophysiology or treatment strategies of female reproductive disorders. Further understanding of the complex interrelationships between metabolic health and female reproductive function has important implications for improving women's health overall.

Abstract
Objectives To evaluate the effects and mechanisms of action of growth hormone (GH) in the recovery of ovarian function in ovarian insufficiency induced by cyclophosphamide (CP) in a mouse model. Materials and methods After inducing ovarian insufficiency by administering 400 mg/kg of CP intraperitoneally to 6-week-old ICR mice, the mice were divided into four groups (control, CP, 1 mg/kg GH, and 2 mg/kg GH) with 10 mice in each group. GH was administered a week later for 7 days. Five mice from each group were sacrificed the next day, and their ovaries were collected for histological examination. The remaining mice were superovulated for in vitro fertilization (IVF). The terminal deoxynucleotidyl transferase dUTP-nick end labeling assay was performed to detect apoptosis. Masson's trichrome staining was used to analyze the degree of fibrosis. To quantify angiogenesis, CD31 immunohistochemistry was performed. Angiogenesis-related gene expression profiles were assessed using quantitative reverse transcription polymerase chain reaction. Results CP induced the loss of non-growing (primordial and primary) follicles while GH significantly protected primordial follicles and increased follicular quality. The CP group showed a decrease in fertilization and blastocyst formation rates in IVF. In contrast, the GH treatment group showed dose-dependent enhanced IVF outcomes. Furthermore, GH treatment decreased apoptosis and stromal fibrosis and increased angiogenesis. Many genes involved in angiogenesis, especially Leptin (Lep), platelet endothelial cell adhesion molecule 1 (Pecam-1), and angiogenin (Ang) were up-regulated in the GH treatment groups. Conclusion GH treatment may promote the recovery of ovarian function in ovarian insufficiency induced by the administration of CP via decreasing apoptosis and stromal fibrosis and upregulating Lep, Pecam-1, and Ang genes.

Abstract
Ischemia/reperfusion (I/R) induced ovarian damage is caused by various diseases such as ovarian torsion, ovarian transplantation, cardiovascular surgery, sepsis, or intra-abdominal surgery. I/R-related oxidative damage can impair ovarian functions, from oocyte maturation to fertilization. This study investigated the effects of dexmedetomidine (DEX), which has been shown to exhibit antiapoptotic, anti-inflammatory, and antioxidant effects, on ovarian I/R injury. We designed four study groups: group 1 (n = 6): control group; group 2 (n = 6): only DEX group; group 3 (n = 6): I/R group; group 4 (n = 6): I/R + DEX group. Then, ovarian samples were taken and examined histologically and immunohistochemically, and tissue malondialdehyde (MDA) and glutathione (GSH) levels were measured. In the I/R group MDA levels, caspase-3, NF-κB/p65, 8-OHdG positivity, and follicular degeneration, edema, and inflammation were increased compared to the control group (p = 0.000). In addition, GSH levels were significantly decreased in the I/R group compared to the control group (p = 0.000). On the other hand, in the I/R + DEX treatment group MDA levels, caspase-3, NF-κB/p65, 8-OHdG positivity, follicular degeneration, edema, and inflammation findings were decreased than in the I/R group (p = 0.000, p = 0.005, p = 0.005, p = 0.001, p = 0.005, respectively). However, GSH levels increased significantly in the I/R + DEX treatment group compared to the I/R group (p = 0.000). DEX protects against ovarian I/R injury through antioxidation and by suppressing inflammation and apoptosis.

The effect of growth hormone on the metabolome of follicular fluid in patients with diminished ovarian reserve. Reprod Biol Endocrinol 2023; 21:21. [PMID: 36849898 PMCID: PMC9969693 DOI: 10.1186/s12958-023-01073-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 02/14/2023] [Indexed: 03/01/2023] Open
Abstract
BACKGROUND Increasing evidence supports that the co-treatment with growth hormone (GH) enhances ovarian response and oocyte quality during controlled ovarian stimulation (COS) in patients with diminished ovarian reserve (DOR). The composition of follicular fluid (FF) plays an essential role in oocyte development and mirrors the communication occurring between the oocyte and follicular microenvironment. However, the effect of GH on the FF metabolome remains unclear. METHODS This prospective observational study recruited DOR patients undergoing in vitro fertilization (IVF) cycles with minimal stimulation protocol for COS. Each patient receiving GH co-treatment was matched to a patient without GH co-treatment by propensity score matching. The FF was collected after isolating oocytes and assayed by gas chromatograph-mass spectrometry (GC-MS) metabolomics. The Pearson correlation was performed to evaluate the relationship between the number of oocytes retrieved and the levels of differential metabolites. The KEGG database was used to map differential metabolites onto various metabolic pathways. RESULTS One hundred thirty-four FF metabolites were identified by GC-MS metabolomics. Twenty-four metabolites, including glutathione, itaconic acid and S-adenosylmethionin (SAM) showed significant differences between the GH and control groups (p-value < 0.05 and q-value < 0.1). In addition, the number of oocytes retrieved was significantly higher in the GH group compared to the control group (3 vs 2, p = 0.04) and correlated with the levels of five differential metabolites. Among them, the levels of antioxidant metabolite itaconic acid were upregulated by GH administration, while SAM levels were downregulated. CONCLUSIONS The co-treatment with GH during COS may improve oocyte development by altering FF metabolite profiles in DOR patients. However, given the downregulation of SAM, a regulator of genomic imprinting, the potential risk of imprinting disturbances should not be neglected.

Abstract
This study aimed to investigate the protective effect of ozone therapy on ovarian reserve, number of ovarian follicles, ovarian morphology in a rat ischaemia reperfusion (IR) injury model. Twenty-four, Wistar Hannover rats were included. The rats were divided into three groups as control, detorsion-only, and ozone therapy + detorsion groups. There was a statistically significant difference in the follicular damage and inflammation scores between the study groups (p = .019, p = .002, respectively). The highest AMH decrease was observed in the detorsion-only group (p = .012). The total damage score was higher in the detorsion-only group than the ozone therapy + detorsion group. Preantral, small and large antral follicle numbers were less in the detorsion-only group than the ozone therapy + detorsion group. The highest postoperative day 7 TAS level was in the ozone therapy + detorsion group. TOS levels did not differ significantly between the study groups. The combination of the ozone therapy with ovarian detorsion is more effective in protecting the ovarian reserve than ovarian detorsion-only.Impact StatementWhat is already known on this subject? Adnexal torsion is a common gynecological emergency in reproductive-age women. The recommended management is the detorsion of the adnexal pedicle in patients with fertility desire.What do the results of this study add? The combination of the medical ozone therapy with conventional surgical ovarian detorsion is more effective in the protection of the ovarian reserve compared to surgical ovarian detorsion.What are the implications of these findings for clinical practice and/or further research? This study speculates that medical ozone therapy in addition to conventional surgical ovarian detorsion could preserve ovarian reserve and function if confirmed in further clinical studies.

Abstract
OBJECTIVES To investigate whether growth hormone (GH) can improve oxidative stress (OS) by affecting) /nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1) in women of advanced age undergoing in vitro fertilization (IVF). METHODS This retrospective study enrolled 141 patients, including 65 aged C patients (patients not treated with GH) and 76 aged GH patients (patients treated with GH). The outcomes included IVF-ET results, OS markers in follicle fluid (FF) and Nrf2 and Keap1 mRNA and protein expressions in granulosa cells (GCs). RESULTS The results showed that GH improved the available blastocyst (p=.047) and implantation rate (p=.043) in women of advanced age undergoing IVF. The malondialdehyde (MDA) content of FF was significantly higher in the aged-C group than in the aged-GH group (p=.013). The antioxidant enzyme activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-px) and catalase (CAT) were significantly lower in the aged-C group than in the aged-GH group (p= .000, p= .049, p= .012 respectively). Nrf2 mRNA and protein expression was significantly higher and Keap1 mRNA and protein expression was lower in the aged-GH group than in the aged-C group (p= .000, p= .000 respectively). CONCLUSIONS The study showed that GH improved embryo quality and implantation rate and alleviated OS in FF, which may be related to Nrf2/Keap1.

Abstract
Secreted by the anterior pituitary gland, growth hormone (GH) is a peptide that plays a critical role in regulating cell growth, development, and metabolism in multiple targeted tissues. Studies have shown that GH and its functional receptor are also expressed in the female reproductive system, including the ovaries and uterus. The experimental data suggest putative roles for GH and insulin-like growth factor 1 (IGF-1, induced by GH activity) signaling in the direct control of multiple reproductive functions, including activation of primordial follicles, folliculogenesis, ovarian steroidogenesis, oocyte maturation, and embryo implantation. In addition, GH enhances granulosa cell responsiveness to gonadotropin by upregulating the expression of gonadotropin receptors (follicle-stimulating hormone receptor and luteinizing hormone receptor), indicating crosstalk between this ovarian regulator and the endocrine signaling system. Notably, natural gene mutation of GH and the age-related decline in GH levels may have a detrimental effect on female reproductive function, leading to several reproductive pathologies, such as diminished ovarian reserve, poor ovarian response during assisted reproductive technology (ART), and implantation failure. Association studies using clinical samples showed that mature GH peptide is present in human follicular fluid, and the concentration of GH in this fluid is positively correlated with oocyte quality and the subsequent embryo morphology and cleavage rate. Furthermore, the results obtained from animal experiments and human samples indicate that supplementation with GH in the in vitro culture system increases steroid hormone production, prevents cell apoptosis, and enhances oocyte maturation and embryo quality. The uterine endometrium is another GH target site, as GH promotes endometrial receptivity and pregnancy by facilitating the implantation process, and the targeted depletion of GH receptors in mice results in fewer uterine implantation sites. Although still controversial, the administration of GH during ovarian stimulation alleviates age-related decreases in ART efficiency, including the number of oocytes retrieved, fertilization rate, embryo quality, implantation rate, pregnancy rate, and live birth rate, especially in patients with poor ovarian response and recurrent implantation failure.

Abstract
BACKGROUND/AIMS Sepsis is an uncontrolled systemic infection, withcomplex pathophysiology that may result in acute lung organ damage and cause multiple organ failure. Although much research has been conducted to illuminate sepsis's complex pathophysiology, sepsis treatment protocols are limited, and sepsis remains an important cause of mortality andmorbidity in intensive care units.Various studies have shown that idebenone (IDE) possesses strong antioxidant properties, which inhibit lipid peroxidation and protect cells from oxidative damage. The present study aimed to evaluate the protective effects of IDE against lung injury in a cecal ligation and puncture (CLP)-induced sepsis rat model. METHODS Male albino Wistar rats were used. The animals were divided into a healthy control (no treatment), CLP, IDE control (200 mg/kg), and CLP + IDE subgroups (50 mg/kg, 100 mg/kg, and 200 mg/kg), with nine rats in each group.IDE was administered 1 h after CLP induction.To evaluate the protective effects of IDE, lung tissues were collected 16 h after sepsis for biochemical, immunohistochemical staining, and histopathological examination. RESULTS IDE significantly ameliorated sepsis-induced disturbances in oxidative stress-related factors, with its effects increasing in accordance with the dose.IDE also abolished histopathological changes in lung tissues associated with CLP.Furthermore, interleukin 1 beta (IL-1β)and tumor necrosis factor-alpha (TNF-α) immunopositivity markedly decreased in the septic rats following IDE treatment. CONCLUSIONS IDE largely mitigated the inflammatory response in sepsis-induced lung injury by decreasing free radicals and preventing lipid peroxidation. The results suggest that IDE may represent a potential novel therapeutic drug for sepsis treatment.

Abstract
Objective The objective of this study is to evaluate the preoperative hematological parameters to predict ovarian torsion in patients with ovarian mature cystic teratoma. We also analyzed the diagnostic value of these makers to predict ovarian necrosis in cases of torsion as well as the effect of torsion on ovarian reserve. Patients and Methods This is a retrospective study of 132 patients who received either laparoscopic or laparotomy surgery for OMCT at a single university hospital. Clinical characteristics and preoperative hematological parameters were compared between patients with or without torsion. Patients with torsion were further classified as infarction and non-infarction group. Preoperative parameters were compared between the two groups as well. Results White blood cell (WBC) count, neutrophil percent, neutrophil count, and neutrophil to lymphocyte ratio (NLR) were higher in the torsion group (n=37) than the non-torsion group (n=95) (p<0.05 for all). Although statistically insignificant, the preoperative anti-Mullerian hormone (AMH) was lower in the torsion group than the non-torsion group (4.07 ± 3.38 vs 6.1 ± 3.6, p=0.122). In cases of torsion, the infarction group showed higher WBC count and lymphocyte count but lower hemoglobin level and platelet to lymphocyte ratio (PLR) than the non-infarction group (p<0.05 for all). Conclusion The WBC count, neutrophil percent, neutrophil count, and NLR were higher in the cases of OMCT with torsion, and these parameters may be useful to diagnose OMCT with torsion. Also, adnexal torsion may deteriorate ovarian reserved as indicated by decreased AMH in torsion group.

[PMID: 32961615 DOI: 10.1111/jog.14503] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2020] [Revised: 07/14/2020] [Accepted: 08/29/2020] [Indexed: 12/12/2022]
Abstract
AIM Ovarian torsion is a common gynecological emergency of reproductive ages, occurring at rates of 2.7-7.4%. This study aimed to evaluate the antioxidant effects of Nebivolol (NEB) and histopathological changes in experimental ischemic (I) and ischemic-reperfusion (I/R) injury in rat ovaries. METHODS Forty-eight adult female rats were randomly separated into six groups as group 1 (control) receiving an oral saline solution for 3 days; group 2 (I) that underwent ischemia for 3 h with the application of atraumatic vascular clips; group 3 (I/R); group 4 (I + NEB) receiving 10 mg/kg NEB by oral gavage 30 min prior to the ischemia induction; group 5 (I/R + NEB) receiving 10 mg/kg NEB, and group 6 (control + NEB) receiving oral 10 mg/kg NEB for 3 days before ischemia induction followed by consequent reperfusion. Ovarian tissue damage was scored by histopathological analysis. Ovarian tissue malondialdehyde (MDA) and glutathione (GSH) levels were measured biochemically. RESULTS The levels of MDA and tumor necrosis factor-alpha (TNF-α), and TUNEL assay positivity scores increased in the I and I/R groups. GSH levels decreased in all case groups (P < 0.05). The oral administration of NEB (10 mg/kg) to the I- and I/R-groups reduced the levels of MDA and TNF-α and TUNEL assay immunopositivity scores (P < 0.05). GSH levels increased in the treatment groups. CONCLUSION The current experimental ovarian torsion study suggests a protective role for NEB against I and I/R injury in rat ovaries. NEB may be a novel agent for decreasing ovarian I/R injury.

Abstract
Objective
The aim of our study was to evaluate the effect of two different doses of lycopene, an antioxidant, on experimentally induced ovarian ischemia/reperfusion (IR) injury in rat model.
Materials and Methods
Twenty-four female rats were randomly divided into four groups: sham operation (group 1), 3-hour ischemia, 3-hour reperfusion (IR) (group 2), and IR + 100 mg/kg lycopene (PO) (group 3), IR + 200 mg/kg of lycopene (group 4). The rats’ superoxide dismutase (SOD), myeloperoxidase (MPO) activities, malondialdehyde (MDA), and glutathione (GSH) levels were calculated. Ovarian tissue damage was assessed using a histopathological scoring system.
Results
Serum parameter levels and histological scores showed that treatment with lycopene may be conservative approach to prevent IR injury after the ovarian detorsion procedure.The improvement with lycopene was higher at 200 mg than at 100 mg. The MPO and MDA values were significantly lower in groups 3 and 4 as compared with group 2 (
p
< 0.05), whereas the MPO and MDA values were lower in group 4 as compared with group 3.The SOD and GSH values were significantly higher in groups 3 and 4 as compared with group 2 (
p
< 0.05), whereas the SOD and GSH values were higher in group 4 as compared with group 3.Tissue damage scores were elevated in the IR group compared with the sham group, but the treatment with different lycopene doses after reperfusion improved the histopathological tissue damage scores.
Conclusion
The results showed that lycopene treatment reduced ovarian IR damage. Antioxidant activity was found to increase in a dose-dependent manner. Lycopene treatment may be conservative approach for ovarian torsion patients after the detorsion procedure to prevent IR damage.

Abstract
Background/aim Adnexal torsion is a common gynaecological emergency, and considered to be a problem mostly in reproductive-age women. To evaluatethe effect of metformin and detorsion treatment on reducing ovarian reserve in an ovarian torsion model. Materials and methods Twenty-four nonpregnant, Wistar Hannover rats were included in the study. Animals were divided into 3 groups: the control group, the detorsion only group, and the metformin + detorsion group. The first group received only laparotomy. In the second group, ovaries were fixed to the abdominal wall after performing 360° ovarian torsion, followed by detorsion after a 3-h period of ischemia. The third group underwent the same torsion and detorsion procedures as the second group, and received 50 mg/kg metformin by gavage for 14 days. Ovarian damage scores, follicle counts, and AMH levels were evaluated. Results The total damage score was significantly increased in the detorsion only group compared to the metformin+detorsion and control groups. Pre-operative/post-operative AMH decreases were statistically significant in negative direction in the detorsion only group when compared to the metformin+detorsion and control groups (P = 0.001). Conclusion Metformin+detorsion treatment may be effective in protecting the ovarian reserve after ovarian torsion.

Abstract
INTRODUCTION Bladder cancer (BCa) is one of the most common and aggressive cancers. It is the sixth most frequently occurring cancer in men and its rate of occurrence increases with age. The current method of BCa diagnosis includes a cystoscopy and biopsy. This process is expensive, unpleasant, and may have severe side effects. Recent growth in the power and accessibility of machine-learning software has allowed for the development of new, non-invasive diagnostic methods whose accuracy and sensitivity are uncompromising to function. OBJECTIVES The goal of this research was to elucidate the biomarkers including metabolites and corresponding genes for different stages of BCa, show their distinguishing and common features, and create a machine-learning model for classification of stages of BCa. METHODS Sets of metabolites for early and late stages, as well as common for both stages were analyzed using MetaboAnalyst and Ingenuity® Pathway Analysis (IPA®) software. Machine-learning methods were utilized in the development of a binary classifier for early- and late-stage metabolites of BCa. Metabolites were quantitatively characterized using EDragon 1.0 software. The two modeling methods used are Multilayer Perceptron (MLP) and Stochastic Gradient Descent (SGD) with a logistic regression loss function. RESULTS We explored metabolic pathways related to early-stage BCa (Galactose metabolism and Starch and sucrose metabolism) and to late-stage BCa (Glycine, serine, and threonine metabolism, Arginine and proline metabolism, Glycerophospholipid metabolism, and Galactose metabolism) as well as those common to both stages pathways. The central metabolite impacting the most cancerogenic genes (AKT, EGFR, MAPK3) in early stage is D-glucose, while late-stage BCa is characterized by significant fold changes in several metabolites: glycerol, choline, 13(S)-hydroxyoctadecadienoic acid, 2'-fucosyllactose. Insulin was also seen to play an important role in late stages of BCa. The best performing model was able to predict metabolite class with an accuracy of 82.54% and the area under precision-recall curve (PRC) of 0.84 on the training set. The same model was applied to three separate sets of metabolites obtained from public sources, one set of the late-stage metabolites and two sets of the early-stage metabolites. The model was better at predicting early-stage metabolites with accuracies of 72% (18/25) and 95% (19/20) on the early sets, and an accuracy of 65.45% (36/55) on the late-stage metabolite set. CONCLUSION By examining the biomarkers present in the urine samples of BCa patients as compared with normal patients, the biomarkers associated with this cancer can be pinpointed and lead to the elucidation of affected metabolic pathways that are specific to different stages of cancer. Development of machine-learning model including metabolites and their chemical descriptors made it possible to achieve considerable accuracy of prediction of stages of BCa.

Abstract
PURPOSE To investigate the effect of melatonin on uterine tissue in the ovariectomized rat model. METHODS Fourty Wistar albino rats were divided into four groups for histologic and immunohistochemical examination. The rats were first numbered randomly and then randomly divided into 4 equal groups: control (group 1), torsion (group 2), torsion+detorsion (group 3) and torsion+detorsion+melatonin (group 4) groups. In addition, four Wistar albino rats were used for western blot analysis in each group. And also, malondialdehyde (MDA) levels were measured biochemically in all rats. RESULTS The histopathological examination of the uterine tissue in rats ovarectomized showed a degeneration in uterine glands, dilation of blood vessels in the internal layer with a thrombosis and bleeding, abnormal nucleuses and vacuolated cytoplasm above and below the nucleus. In torsion group, the apoptotic cells increased in luminal epithelium and gland cells. In the melatonin group showed that the Bcl2 negative effect on the uterine epithelium and did not lead to apoptotic cells. CONCLUSION The increase in vascular endothelial growth factor expression resulted in the rearrangement of endothelial cell growth and the induction of angiogenesis.

Abstract
BACKGROUND The present study aimed to investigate the effects of hydrogen rich saline solution (HRSS) in a rat model of ovarian ischemia-reperfusion injury. METHODS Thirty-six female Wistar-albino rats were grouped randomly, into six groups of six rats. The groups were classified as: sham (S), hydrogen (H), torsion (T), torsion/detorsion (TD), hydrogen-torsion (HT), and hydrogen-torsion/detorsion (HTD). Bilateral adnexal torsion was performed for 3h in all torsion groups. HRSS was given 5ml/kg in hydrogen groups intraperitoneally. Malondialdehyde (MDA) and glutathione-S-transferase (GST) levels were measured in both the plasma and tissue samples. Tissue sections were evaluated histopathologically, and the apoptotic index was detected by TUNEL assay. The results were analyzed by Kruskal-Wallis and Pearson chi-square tests using computer software, SPSS Version 20.0 for Windows. RESULTS The MDA levels were higher and GST levels were lower in the torsion and detorsion groups when compared to other groups, but the differences were insignificant (P>0.05). The MDA levels were lower and GST levels were higher in the HT and HTD groups compared with the T and TD groups (P>0.05). Follicular injury, edema, vascular congestion, loss of cohesion and apoptotic index were higher in the torsion groups but decreased in the groups that received HRSS. CONCLUSIONS According to histopathological and biochemical examinations, HRSS is effective in attenuating ischemia-reperfusion induced ovary injury.

Abstract
The aim of this study was to evaluate the effects of aliskiren, direct renin inhibitor, as an antioxidant and tissue protective agent and evaluate the molecular, biochemical, and histopathological changes in experimental ischemia and ischemia/reperfusion injury in rat ovaries. Forty-eight female rats were randomly divided into eight groups: in Group 1, only sham operation was performed. Group 2 received 100 mg/kg aliskiren and sham operated. In Group 3, 3 h-period of bilateral ovarian ischemia was applied. Group 4 received a 3-h period of ischemia followed by 3 h of reperfusion. Groups 5 and 6 received 50 and 100 mg/kg, respectively, of aliskiren and bilateral ovarian ischemia was applied (after a 3-h period of ischemia, both ovaries were surgically removed). To Groups 7 and 8, 50 and 100 mg/kg of aliskiren were administered, respectively, and the induction of ischemia was performed. At the end of a 3-h period of ischemia, bilateral vascular clips were removed, and 3 h of reperfusion continued. After the experiments, IL-1β, IL-6, TNF-α, and iNOS mRNA expressions and SOD, GSH, MDA, renin, and angiotensin-II levels were determined and histopathological changes were examined in rat ovaries. Aliskiren treatment normalized excessive changes in cytokine and oxidative stress markers in both ischemia and ischemia/reperfusion injury. Histopathologically, treatment with aliskiren ameliorated the development of ischemia and/or ischemia/reperfusion tissue injury. This study concluded that aliskiren treatment is effective in reversing ischemia and/or ischemia/reperfusion induced ovary damage via the improvement of oxidative stress, reduction of inflammation, and suppression of the renin-angiotensin aldosterone system.

Abstract
This study evaluated the effects of N-acetylcysteine (NAC) and enoxaparin on ovarian tissue preservation, ovarian reserve and oxidative damage following ovarian torsion/detorsion injury. Rats were divided into four groups (n = 6/group): control; ischaemia/reperfusion (I/R); I/R + NAC; I/R + enoxaparin. Twenty-four hours after detorsion, ovarian tissues were collected for histopathological analysis and measurement of tissue 8-OHdG, GSH, MDA, MPO and SOD concentrations, as well as pre- and post-operative circulating AMH concentrations. Administration of NAC resulted in more pre-antral follicles compared with enoxaparin treatment and haemorrhage and follicle cell degeneration were more pronounced in I/R + enoxaparin group than I/R + NAC group. Both NAC and enoxaparin led to a significant reduction in ovarian tissue 8-OHdG (P = 0.004 and P = 0.01, respectively) and MPO (P = 0.013 and P = 0.023, respectively) concentrations compared with I/R group, indicating a protective effect against I/R oxidative damage. Only NAC-treated animals showed a significant increase in GSH and SOD concentrations and decrease in MDA concentrations compared with I/R group (P = 0.007, P = 0.024 and P = 0.026, respectively). These results indicate that NAC is more effective than enoxaparin in minimizing ovarian damage and preserving ovarian reserve following ovarian torsion.

Abstract
Among the different causes of gynecological acute pelvic pain, ovarian torsion represents a surgical emergency. It is a rare case in the pediatric/adolescent aged group
that must be included in the differential diagnosis of any girl with abdominal pain or
pelvic/abdominal mass. Current recommendations suggest that laparoscopic detorsion should be performed in order to preserve the integrity of the ovaries and fertility,
although oophoropexy may be considered in case of severe necrosis. Nevertheless,
maintaining the circulation of the ovary after detorsion deteriorates the tissue injury
and leads to a pathologic process called ischaemia/reperfusion (I/R) injury, which is
characterized by oxidative stress. During the detorsion process, an excess amount of
molecular oxygen is supplied to the tissues, and reactive species of oxygen (ROS)
such as superoxide radical (O2-), hydrogen peroxide (H2O2), hydroxyl radical (OH•),
as well as reactive nitrogen species (RNS) are produced in excess. ROS, RNS and
their toxic products cause DNA damage and lipid peroxidation in the cellular and
mitochondrial membranes, leading to cell death. In spite of attention on this topic,
currently there is no shared and clear evidence about the use of anti-inflammatory
and antioxidant agents to prevent I/R damage after laparoscopic ovarian detorsion.
Considering this element, future research should aim to develop shared protocols for
the clinical use (route of application, dosage and time of application) of antioxidants
after laparoscopic management of this condition.

AIM This study investigated the effects of the antioxidant agents, ozone (O) and ellagic acid (EA), on ischemia/reperfusion (I/R) injuries developed from an ovarian torsion-detorsion model. MATERIALS AND METHODS Arteries in the left ovaries of rats were clamped for two hours to achieve torsion, and then the clamps were removed for a two-hour detorsion period. Thirty-five female Sprague-Dawley rats were randomly divided into five groups: control: administered only with anesthesia, rats were not subjected to torsion-detorsion; I/R: subjected to torsion and subsequent detorsion, without administering any treatment agent; and I/R + EA, I/R + O and I/R + O + EA: subjected to torsion and detorsion processes and administered with EA, O or EA + O at the 75th minute of torsion. The rats were then sacrificed under general anesthesia and the ovarian tissues were excised. The tissues were homogenized and levels of glutathione reductase, catalase, superoxide dismutase and malondialdehyde (MDA) were analyzed. Tissue damage was evaluated in terms of histopathological parameters, such as hemorrhage, congestion, edema and inflammation. RESULTS Antioxidant enzyme activity and MDA levels in the ovary tissue increased in the I/R group and decreased in the O, EA and O + EA groups (P < 0.05). Histopathological examination revealed that tissue damage in the O, EA and O + EA groups decreased in comparison with the I/R group (P < 0.05). CONCLUSIONS These biochemical and histopathological findings suggest that EA and O are effective against ovarian I/R injury.

Growth Hormone Ameliorates the Radiotherapy-Induced Ovarian Follicular Loss in Rats: Impact on Oxidative Stress, Apoptosis and IGF-1/IGF-1R Axis. PLoS One 2015; 10:e0140055. [PMID: 26465611 PMCID: PMC4605641 DOI: 10.1371/journal.pone.0140055] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2015] [Accepted: 09/21/2015] [Indexed: 01/25/2023] Open
Abstract
Radiotherapy is one of the standard cytotoxic therapies for cancer. However, it has a profound impact on ovarian function leading to premature ovarian failure and infertility. Since none of the currently available methods for fertility preservation guarantees future fertility, the need for an effective radioprotective agent is highly intensified. The present study investigated the mechanisms of the potential radioprotective effect of growth hormone (GH) on γ irradiation-induced ovarian failure and the impact of the insulin like growth factor 1 (IGF-1) in the underlying protection. Immature female Sprague-Dawley rats were either exposed to single whole body irradiation (3.2 Gy) and/or treated with GH (1 mg/kg s.c). Experimental γ-irradiation produced an array of ovarian dysfunction that was evident by assessment of hormonal changes, follicular development, proliferation marker (PCNA), oxidative stress as well as apoptotic markers. In addition, IGF-1/IGF-1R axis expression was assessed using real-time PCR and immunolocalization techniques. Furthermore, after full maturity, fertility assessment was performed. GH significantly enhanced follicular development and restored anti-Mullerian hormone serum level as compared with the irradiated group. In addition, GH significantly ameliorated the deleterious effects of irradiation on oxidative status, PCNA and apoptosis. Interestingly, GH was shown to enhance the ovarian IGF-1 at transcription and translation levels, a property that contributes significantly to its radioprotective effect. Finally, GH regained the fertility that was lost following irradiation. In conclusion, GH showed a radioprotective effect and rescued the ovarian reserve through increasing local IGF-1 level and counteracting the oxidative stress-mediated apoptosis.

Abstract
The aim of this study was to examine the effects of amlodipine (AML) in rat testicular torsion/detorsion damage. In this study, rats were divided into eight groups: (i) sham; (ii) testicular ischaemia, 2 h of ischaemia; (iii) testicular ischaemia/reperfusion (I/R), 2 h of ischaemia followed by 2 h of reperfusion; (iv) ischaemia + AML (5 mg kg(-1)) administered 30 min before ischaemia; (v) ischaemia + AML (10 mg kg(-1)) administered 30 min before ischaemia; (vi) and (vii) I/R + AML (5 mg kg(-1)) and I/R + AML (10 mg kg(-1)) administered 1.5 h after the induction of ischaemia, respectively, and at the end of a 2-h ischaemia period and a 2-h reperfusion period applied; and (viii) sham + AML (10 mg kg(-1)). Significant decreases in levels of superoxide dismutase and glutathione were observed in ischaemia and reperfusion groups when compared with healthy controls. These antioxidant levels increased in AML groups while malondialdehyde levels significantly decreased. While increases in tumour necrosis factor-alpha and transforming growth factor-beta levels were found in the torsion and detorsion groups, significant decreases in the levels of these inflammatory cytokines were observed in the treatment groups. These results demonstrate that AML significantly produced protective effects on testis tissue damage that occurs in the torsion/detorsion model via biochemical, histopathological and molecular pathways.

Abstract
The somatotropic axis, consisting of growth hormone (GH), hepatic insulin-like growth factor I (IGF-I), and assorted releasing factors, regulates growth and body composition. Axiomatically, since optimal body composition enhances reproductive function, general somatic actions of GH modulate reproductive function. A growing body of evidence supports the hypothesis that GH also modulates reproduction directly, exerting both gonadotropin-dependent and gonadotropin-independent actions in both males and females. Moreover, recent studies indicate GH produced within reproductive tissues differs from pituitary GH in terms of secretion and action. Accordingly, GH is increasingly used as a fertility adjunct in males and females, both humans and nonhumans. This review reconsiders reproductive actions of GH in vertebrates in respect to these new conceptual developments.

Abstract
BACKGROUND To investigate the protective effect of ethyl pyruvate (EP), an anti-oxidant agent, against ischemia-reperfusion injury in a rat model of ovarian torsion, considering biochemical and histopathological aspects. METHODS Forty Wistar Albino rats were divided into five groups: Group I, sham operation; Group II, ischemia alone, Group III, ischemia-reperfusion; Group IV, ischemia-reperfusion+50 mg/kg EP; and Group V, ischemia-reperfusion+100 mg/kg EP. Through laparotomy, 360° torsion was performed and maintained for 3 h, and detorsion was maintained for a further 3 h. Intraperitoneal EP was given 30 min before the surgical procedure. Ovarian tissues and blood samples were obtained after surgery. Malondialdehyde (MDA) and asymmetric dimethyl arginine (ADMA) levels were measured in both plasma and tissue samples. Tissue sections were evaluated histopatologically. Analysis of variance was used for statistical analyses. RESULTS In both serum and tissue samples, ADMA and MDA levels were found to be significantly lower in the EP groups compared with the ischemia alone and ischemia-reperfusion groups (p=0.0001). However, no significant difference was found between groups treated with 50 mg/kg or 100 mg/kg EP. On histopathological evaluation, the total tissue injury score was found to be lower in rats treated with EP. No significant difference was detected between groups treated with 50 mg/kg or 100 mg/kg EP. CONCLUSION Ethyl pyruvate may exert positive effects in ischemia-reperfusion injury in cases of ovarian torsion. However, no difference was detected between 50 mg/kg and 100 mg/kg EP.

Abstract
OBJECTIVE To investigate the effect of enoxaparin on ovarian reserve and serum antimüllerian hormone (AMH) levels in a rat ovarian torsion model. DESIGN Experimental study. SETTING Experimental surgery laboratory in a training and research hospital. ANIMAL(S) Fourteen female Wistar Hannover rats. INTERVENTION(S) 1) Control group received no special treatment other than abdominal exposure; 2) detorsion-only group received bilateral adnexal torsion (3-hour ischemia), and then after 3-hour torsion period, detorsion (reperfusion) was performed; and 3) detorsion-enoxaparin group received 0.5 mg/kg enoxaparin subcutaneously 2 hours before the same surgery as the detorsion-only group and a second 0.5 mg/kg dose of enoxaparin 24 hours after the first surgeries. Apart from the surgeries, preoperative and postoperative 1-mL blood samples were drawn from the right jugular vein of each rat. MAIN OUTCOME MEASURE(S) Preoperative and postoperative serum AMH levels, histopathologic damage scores, and follicle counts in the ovarian tissue of the rats. RESULT(S) Vascular congestion and hemorrhage scores were higher in the detorsion-enoxaparin group than in the detorsion-only and control groups. The number of small antral follicles was smaller in the detorsion-only group than in the control group. The difference in the pre- and postoperative AMH levels was higher in the detorsion-only group than in the control and detorsion-enoxaparin groups. CONCLUSION(S) The combination of enoxaparin therapy with conventional ovarian detorsion is more effective in protecting the ovarian reserve than detorsion alone.

Abstract
Oxytocin (OT), a neurohypophysial nonapeptide, plays dual role as a neurotransmitter/neuromodulator and a hormone. It has also well known protective properties against ischemia/reperfusion organ damage. This study investigated the effect of OT on experimentally induced ovarian torsion/de-torsion ischemia/reperfusion (I/R) injury in rats. Sprague-Dawley rats were assigned to five treatment groups (n=7/group): Group 1, sham-operated; Group 2, torsion; Group 3, 80 IU/kg of OT administration 30 min prior to torsion; Group 4, torsion/de-torsion; and Group 5, torsion followed by 80 IU/kg of OT administration 30 min prior to de-torsion. OT administration significantly decreased the tissue malondialdehyde (MDA) levels in both the torsion and OT group (Group 3), and torsion/de-torsion OT group (Group 5) in comparison with the torsion-only group (Group 2) and torsion/de-torsion group (Group 4). Histopathological finding scores including follicular degeneration, edema, hemorrhage, vascular congestion, and infiltration by inflammatory cells were found to be significantly decreased in the torsion and OT group (Group 3), and torsion/de-torsion OT group (Group 5) when compared with the torsion-only group (Group 2) and torsion/de-torsion group (Group 4). In conclusion, these results, verified with histopathologic evaluation and biochemical assays, suggest a probable protective role for OT in ischemia and I/R injury in rat ovaries.

Abstract
OBJECTIVE To investigate the protective effect of quercetin (QE), an anti-inflammatory and anti-oxidant agent, on torsion-detorsion induced histopathological changes and blood IMA levels in experimental ovarian ischemia-reperfusion (IR) injury. STUDY DESIGN Twenty-four female Wistar rats were randomly divided into four groups in this study (n=6). Group I, (sham operation); Group II, torsion-detorsion plus saline (IR); Group III, torsion-detorsion plus solvent (dimethylsulfoxide: DMSO, IR+DMSO); Group IV, torsion-detorsion plus 15 mg/kg/bw quercetin (IR+QE) injected intraperitoneally 30 min prior to detorsion. After 3h of reperfusion, the right ovaries were removed surgically. The ovary tissue samples were fixed in 10% formalin solution for histopathological and immunohistochemical examination. Blood samples were obtained at the end of the procedures for each group of animals. RESULTS Ovarian sections in Groups II and III showed higher follicular cell degeneration, hemorrhage, vascular congestion and edema when compared with Group I. Administration of quercetin in rats significantly prevented degenerative changes in the ovary. Significantly less histopathological changes were found in Group IV compared with Groups II and III. Caspase-3 and TUNEL positive cells were detected in the ovarian surface, follicle epithelium, and stromal cells in all experimental groups, and there was a significant increase in Groups II and III compared with Group I (P<0.05). Treatment with quercetin decreased the number of caspase-3 and TUNEL positive cells. IR increased the ischemia modified albumin (IMA) levels in comparison to the sham group (1.06 ± 0.10 ABSU and 0.92 ± 0.08 ABSU, P<0.05). Quercetin administration before IR reduced the levels of IMA (0.93 ± 0.08 ABSU, P<0.05). CONCLUSION Administration of quercetin is effective in preventing tissue damage induced by IR injury in ovaries.

Abstract
The aim of this study was to evaluate the role of vitamin E in follicular degeneration and to assess histopathological and biochemical changes following ischemia-reperfusion (IR) injury in rat ovaries. Twenty-eight Wistar albino rats were randomly divided into four groups: sham, 4h torsion, 24h detorsion, and a vitamin E group. Thirty minutes before detorsion, a single dose of 200mg/kg vitamin E was administered intraperitoneally. The ovarian histology score was determined, serum levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were measured. The apoptosis of granulosa cells and the phospho-c-jun N-terminal kinase (p-JNK) and phospho-p38 (p-p38) immunoreactivities of these cells were determined. MDA and MPO levels were significantly increased in the torsion and detorsion groups. Hemorrhage, edema, and congestion were also apparent in these groups. In addition, the apoptotic index and the immunoreactivity of p-JNK were highest in the detorsion group, which also showed marked follicular degeneration. However, p-p38 activity was not affected by torsion-detorsion (TD) induction. Vitamin E ameliorated TD-induced histological alterations. It also decreased serum levels of MDA and MPO, reduced the activity of p-JNK in the ovaries, and reduced numbers of apoptotic follicular cells. In conclusion, these data indicate that vitamin E attenuated ovarian follicular degeneration by inhibiting the immunoreactivity of p-JNK and reducing the apoptosis of granulosa cells.

STUDY DESIGN Group 1: sham operation; Group 2: sham operation and bosentan 60 mg/kg; Group 3: bilateral ovarian ischaemia; Group 4: 3-h period of ischaemia followed by 3h of reperfusion; Groups 5 and 6: bosentan 30 and 60 mg/kg, respectively, with bilateral ovarian ischaemia applied 30 min later; the bilateral ovaries were removed after 3h of ischaemia; Groups 7 and 8: 3h of bilateral ovarian ischaemia was applied, with bosentan 30 and 60 mg/kg, respectively, administered 2.5h after the induction of ischaemia; following the 3-h period of ischaemia, 3h of reperfusion was applied, after which the ovaries were removed. RESULTS Ischaemia and I/R decreased superoxide dismutase (SOD) activity and the level of glutathione (GSH) in ovarian tissue, but increased the level of malondialdehyde (MDA) significantly compared with the sham operation group. Bosentan 30 and 60 mg/kg before ischaemia and I/R decreased the MDA level and increased SOD activity and the GSH level in the experimental groups. The serum levels of the inflammatory cytokines interleukin (IL)-1β, IL-6 and tumour necrosis factor-α were also measured in the I/R injury model in rat ovaries. The levels of these cytokines were significantly higher in the ischaemia and I/R groups compared with the sham operation and sham operation plus bosentan groups. The histopathological findings also demonstrated the protective role of bosentan against I/R-induced injury in rat ovaries. CONCLUSION Administration of bosentan protects the ovaries against oxidative damage and I/R-induced injury.

Abstract
Ovarian cortex cryobanking is a technique of fertility preservation that led to the birth of about 20 children in the world since 2004. Its main limitations are low follicular survival rate after thawing and transplantation and the risk of disease reintroduction. A lot of research is currently conducted in order to optimize both efficacy and safety of the graft and to develop alternative techniques to restore fertility. These advances will allow oncologists to offer this technique to a growing number of patients in the context of fertility preservation (for medical or social indications), but also in other indications such as puberty induction or menopause treatment.

Selenium has a protective effect on ischemia/reperfusion injury in a rat ovary model: biochemical and histopathologic evaluation. J Pediatr Surg 2012; 47:1735-41. [PMID: 22974615 DOI: 10.1016/j.jpedsurg.2012.03.053] [Citation(s) in RCA: 45] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2011] [Revised: 03/15/2012] [Accepted: 03/19/2012] [Indexed: 11/30/2022]
Abstract
BACKGROUND/PURPOSE The aim of the study was to evaluate the effects of selenium (Se) on ischemia/reperfusion (I/R) injury in rat ovaries. METHODS Thirty-five female Sprague-Dawley rats were randomly divided into 5 groups (n = 7): sham (S), I/R1, I/R2, Se1, and Se2. In the I/R1 and Se1 groups, 4 hours of ischemia was followed by 6 hours of reperfusion, and in the I/R2 and Se2 groups, 4 hours of ischemia was followed by 12 hours of reperfusion. In the Se groups, 30 minutes before reperfusion, a single dose of 0.2 mg/kg Se was administered intraperitoneally. The ovarian tissue levels of malondialdehyde (MDA) and nitric oxide (NO), and the activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were measured biochemically. Tissue damage to ovarian tissue was scored by histopathologic examination. RESULTS The I/R groups had significantly higher MDA levels and lower CAT, SOD, and GPx activities than the sham group (P < .05). Although NO levels were significantly higher in the I/R1 group than in the sham group (P < .05), the NO levels in the I/R2 and sham groups were similar. Selenium pretreatment significantly lowered tissue MDA and NO levels and increased tissue SOD and GPx activities in the Se groups, compared with those in the I/R groups (P < .05). Catalase activities were significantly higher in the Se2 group than in the I/R2 group (P < .05). Catalase activities were higher in the Se1 group than in the I/R1 group, but the difference was not statistically significant. Treatment with Se significantly decreased the ovarian tissue damage scores in the Se2 group compared with those in the I/R2 group (P < .05). CONCLUSION Selenium is effective in preventing tissue damage induced by I/R in rat ovaries.
